iAds still refuse to work - cocoa-touch

Edit: Here's my AppDelegate as well (part of it)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]];
GameViewController *gameViewController = [[GameViewController alloc]init];
NSLog(#"NSLOG %#", [[gameViewController view]class]);
_bannerViewController = [[BannerViewController alloc]initWithContentViewController:gameViewController];
self.window.rootViewController = _bannerViewController;
[self.window makeKeyAndVisible];
return YES;
}
I am about to give up. I have tried 5 different ways just these past few days to get literally one single iAd to show correctly and as simple as Apple makes it seem, literally 100% of the time I either see no ad or get an error. I have followed the Apple documentation EXACTLY.
The only clue I have is in these two lines
GameViewController *gameViewController = [[GameViewController alloc]init];
NSLog(#"NSLOG %#", [[gameViewController view]class]);
Which are in my app delegate. The NSLog gives me "UIView". No. Why? Why would that ever be a UIView, it should be an SKView, because GameViewController was pre-written for me by apple for sprite kit. How could that possibly give me the wrong object?
I am getting 'NSInvalidArgumentException', reason: '-[UIView scene]: unrecognized selector sent to instance 0x174191780' which others have recommended to fix by putting the originalContent statement but I already have that and it isn't working.

I figured it out. The answer, as I thought it would be, was incredibly simple and quite mind-boggling that Apple wouldn't put some sort of warning in their documentation, but then again maybe I am just too much of a noob and we are expected to know these kinds of things.
The answer, is that init was never being called in GameViewController, instead, initWithCoder: was being called. Once I NSLogged the init method and saw it wasn't being called, I figured this out.

AdMob integration destorts the Hello World Label text

I have created a simple hello world project for cocos2d-x 3.2. Added AdMob banner. The essence of adding banner is to create a view, then add into that view first the cocos2d-x content and then banner content:
UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self addChildViewController:_contentController];
[contentView addSubview:_contentController.view];
[_contentController didMoveToParentViewController:self];
[contentView addSubview:_bannerView];
self.view = contentView;
The result is that on iPhone, iPhone Retina, iPad Retina (but not in iPad) the Hello World text is distorted like this:
At the same time that stats text is not distorted:
I cannot understand what happens and why. Here is my full code:
.hfile
#import <UIKit/UIKit.h>
#interface BannerViewController : UIViewController
- (instancetype)initWithContentViewController:(UIViewController *)contentController;
- (void) hideBanner;
- (void) showBanner;
#end
and hers is .mm file
#import "BannerViewController.h"
#import "GADBannerView.h"
#interface BannerViewController () <GADBannerViewDelegate>
#end
#implementation BannerViewController {
GADBannerView *_bannerView;
UIViewController *_contentController;
Boolean _bannerLoaded;
}
- (instancetype)initWithContentViewController:(UIViewController *)contentController
{
self = [super init];
if (self != nil) {
// use kGADAdSizeBanner for a small banner in iPad
_bannerView = [[GADBannerView alloc] initWithAdSize: kGADAdSizeSmartBannerPortrait]; // scaled banner dependent on device size
_bannerView.adUnitID = #"ca-app-pub-874958723945898/8247587858";

self.view = contentView;
}

#else
bannerFrame.size = [_bannerView sizeThatFits:contentFrame.size];
#endif
bannerFrame.origin.x = (contentFrame.size.width - bannerFrame.size.width) / 2;
if (_bannerLoaded) {
//contentFrame.size.height -= bannerFrame.size.height;
bannerFrame.origin.y = contentFrame.size.height - bannerFrame.size.height;
} else {
bannerFrame.origin.y = contentFrame.size.height;
}

_bannerView.frame = bannerFrame;
}
- (void)viewDidLoad {

[self.view addSubview:_bannerView];

[_bannerView loadRequest:request];
}
- (void)adViewDidReceiveAd:(GADBannerView *)bannerView
{
NSLog(#"adViewDidReceiveAd");
_bannerLoaded = YES;
[UIView animateWithDuration:0.25 animations:^{
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];
}
- (void)adView:(GADBannerView *)view didFailToReceiveAdWithError:(GADRequestError *)error
{

//TODO:
}
- (void)dealloc {
_bannerView.delegate = nil;
[_bannerView release];
[super dealloc];
}
#end
// </GADBannerViewDelegate>
And I use it in AppController.mm like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Add the view controller's view to the window and display.
window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];
// Init the CCEAGLView
CCEAGLView *eaglView = [CCEAGLView viewWithFrame: [window bounds]
pixelFormat: kEAGLColorFormatRGBA8
depthFormat: GL_DEPTH24_STENCIL8_OES
preserveBackbuffer: NO
sharegroup: nil
multiSampling: NO
numberOfSamples: 0];
// Use RootViewController manage CCEAGLView
_viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
_viewController.wantsFullScreenLayout = YES;
_viewController.view = eaglView;
_bannerViewController = [[BannerViewController alloc] initWithContentViewController:_viewController];
// Set RootViewController to window
if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)
{
// warning: addSubView doesn't work on iOS6
[window addSubview: _bannerViewController.view];
//[window addSubview: _viewController.view];
}
else
{
// use this method on ios6
[window setRootViewController:_bannerViewController];
// [window setRootViewController:_viewController];
}
[window makeKeyAndVisible];
[[UIApplication sharedApplication] setStatusBarHidden:true];
// IMPORTANT: Setting the GLView should be done after creating the RootViewController
cocos2d::GLView *glview = cocos2d::GLView::createWithEAGLView(eaglView);
cocos2d::Director::getInstance()->setOpenGLView(glview);
cocos2d::Application::getInstance()->run();
return YES;
}
What is wrong here?
I have found the problem. I appears that there is a time in hours written with black color like in the image, which on on the Hello World label and hence it distorts:
The time is shown is simulators status bar. In order to hide it I added this:
//fix not hide status on ios7
- (BOOL)prefersStatusBarHidden
{
return YES;
}
into BannerViewController class and that's it!

UIImagePIckerController appears but the camera does not start

Yes, It might be a duplicate question of this. But since it didn't get an answer, I will be more specific on the case and code:
I have 3 involved UIViewControllers:
WelcomeView - the first one
TakePhotoViewController - the second one who is delegate of the OverlayviewController
OverlayViewController - custom view for the camera.
Scenario:
User enter WelcomeView and clicks on a button to be transfered with segue to TakeView.
UIImageViewController is being opened to take a photo.
The user clicks on cancel button - didCancelCamera method in TakePhotoViewController is being invoked and he returns to WelcomeView
The user leaves the app.
The user re-opens the app and perform step 1 again.
THE IMAGE PICKER IS NOT BEING OPENED. I COULD TAKE A PHOTO AND IT'S OK - BUT THE USER CAN'T SEE WHAT HE IS TAKING.
OverlayViewController.h
#interface OverlayViewController : BaseViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate>
#property (nonatomic,weak) id<OverlayViewControllerDelegate> delegate;
#property (nonatomic,retain) UIImagePickerController *imagePickerController;
#end
OverlayViewController.m:

self.imagePickerController.delegate = self;
}
return self;
}

self.view.backgroundColor = [UIColor clearColor];

[self.delegate didCancelCamera];
}

{
self.imagePickerController.sourceType = sourceType;
if (sourceType == UIImagePickerControllerSourceTypeCamera)
{
self.imagePickerController.showsCameraControls = NO;
if ([[self.imagePickerController.cameraOverlayView subviews] count] ==0)
{
CGRect overlayViewFrame = self.imagePickerController.cameraOverlayView.frame;
CGRect newFrame = CGRectMake(0.0, CGRectGetHeight(overlayViewFrame)-self.view.frame.size.height-10.0, CGRectGetWidth(overlayViewFrame), self.view.frame.size.height + 10.0);
self.view.frame = newFrame;
[self.imagePickerController.cameraOverlayView addSubview:self.view];
}
}
}
- (void)finishAndUpdate
{
[NSThread detachNewThreadSelector:#selector(threadStartAnimating:) toTarget:self withObject:nil];
[self.delegate didFinishWithCamera]; // tell our delegate we are done with the camera
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self finishAndUpdate];
}
TakePhotoViewController.h
#interface TakePhotoViewController : BaseViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate,OverlayViewControllerDelegate>
#property (nonatomic, retain) OverlayViewController *overlayViewController;
#end
TakePhotoViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
// Insert the overlay
self.overlayViewController = (OverlayViewController *)[sb instantiateViewControllerWithIdentifier:#"Overlay"];
self.overlayViewController.delegate = self;
}
- (void)viewDidUnload
{
self.overlayViewController = nil;
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (void)openImagePicker {
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
[self showImagePicker:UIImagePickerControllerSourceTypeCamera];
}
else{
[self showImagePicker:UIImagePickerControllerSourceTypePhotoLibrary];
}
}
- (void)viewDidAppear:(BOOL)animated{
if (appDelegate.shouldOpenPicker){
[self openImagePicker];
}
}
- (void)showImagePicker:(UIImagePickerControllerSourceType)sourceType
{
if ([UIImagePickerController isSourceTypeAvailable:sourceType])
{
[self.overlayViewController setupImagePicker:sourceType];
[self presentViewController:self.overlayViewController.imagePickerController animated:YES completion:nil];
}
}
-(void)didCancelCamera{
[[self.overlayViewController.imagePickerController presentingViewController] dismissViewControllerAnimated:NO completion:^ {
[self performSegueWithIdentifier:#"fromTakeToWelcome" sender:self];
}];
}
I found the bug.
The method
-(void)didCancelCamera from TakePhotoViewController is being called when the user clicks on - (IBAction)cancelImagePicker:(id)sender in OverlayViewController.
However, somehow the code in didCancelCamera causes viewDidAppear method of TakePhotoViewController to be invoked again and reopen the image picker.
I have no idea why
[[self.overlayViewController.imagePickerController presentingViewController] dismissViewControllerAnimated:NO completion:^ {
[self performSegueWithIdentifier:#"fromTakeToWelcome" sender:self];
}];
causes the viewDidAppear method of that view (TakePhoto) being recalled again.
Hope that it will help someone

ADBannerView Full Ad Orientation Not Changing

I use the code right out of the Apple iAd Suite demo code to implement my banner ad with a tab bar controller. It was working fine until recently, when I noticed that the test ads became more colorful, and not just black rectangles with the words "test ad" in them.
However, I am now seeing that, while the banner view rotates okay, the full ad is only showing in landscape orientation. The rest of the app rotates okay, but no matter what orientation the device is in, the full add only shows in landscape.
I don't see how to control this.
Here is the code:
#import "BannerViewController.h"
NSString * const BannerViewActionWillBegin = #"BannerViewActionWillBegin";
NSString * const BannerViewActionDidFinish = #"BannerViewActionDidFinish";
#implementation BannerViewController
{
ADBannerView *_bannerView;
UIViewController *_contentController;
}
- (id)initWithContentViewController:(UIViewController *)contentController
{
self = [super init];
if (self != nil) {
_bannerView = [[ADBannerView alloc] init];
_bannerView.delegate = self;
_contentController = contentController;
}
return self;
}
- (void)loadView
{
UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[contentView addSubview:_bannerView];
[self addChildViewController:_contentController];
[contentView addSubview:_contentController.view];
[_contentController didMoveToParentViewController:self];
self.view = contentView;
}
- (void)viewDidUnload
{
[super viewDidUnload];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return [_contentController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}
- (void)viewDidLayoutSubviews
{
if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation)) {
_bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
} else {
_bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
}
CGRect contentFrame = self.view.bounds;
CGRect bannerFrame = _bannerView.frame;
if (_bannerView.bannerLoaded) {
contentFrame.size.height -= _bannerView.frame.size.height;
bannerFrame.origin.y = contentFrame.size.height;
} else {
bannerFrame.origin.y = contentFrame.size.height;
}
_contentController.view.frame = contentFrame;
_bannerView.frame = bannerFrame;
}
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
[UIView animateWithDuration:0.25 animations:^{
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];
}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
[UIView animateWithDuration:0.25 animations:^{
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];
}
- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave
{
[[NSNotificationCenter defaultCenter] postNotificationName:BannerViewActionWillBegin object:self];
return YES;
}
- (void)bannerViewActionDidFinish:(ADBannerView *)banner
{
[[NSNotificationCenter defaultCenter] postNotificationName:BannerViewActionDidFinish object:self];
}
#end
In the shouldAutorotateToInterfaceOrientation: method, the interfaceOrientation is portrait, and it is evaluating to true. The full ad still shows in landscape.
What is causing this and how can I control it?
It seems only one orientation is supported in Sandboxing mode.

Objective-C, Need help creating an AVAudioPlayer singleton

I'm working on a soundboard app, that has several pages of buttons to play sound effects with a stop button on every page should the user wish to manually interrupt the clip. I'm using avaudioplayer in each view to play the sound upon pressing the button for that clip. It works fine until the view is changed. If a user jumps to a new page the sound keeps playing and the stop button stops working even if they return to the original view. Pressing a sound button no longer interrupts the running sound resulting in two sounds over each other.
From googling and searching this site, I know the issue is that each view change creates a new instance of the player and the remedy is to create a singleton class. Unfortunately I have yet to find any further examples of how to actually do this. If someone could provide or point the way to a beginners guide for creating an avaudioplayer singleton I would really appreciate it. All I need to be able to do is pass the file name to the shared player and start play with a sound clip button and have the stop button stop sounds no matter what view the user is on. I am using the ios 5.1 sdk with storyboards and ARC enabled.
My solution, as used in one of my own projects, is posted beneath. Feel free to copy-and-paste, I intend to open-source this project once it's finished :)
A preview of the player can be seen on YouTube: http://www.youtube.com/watch?v=Q98DQ6iNTYM

From any view controller inside the app I start audio with the following code:
- (void)playAudioWithURL:(NSURL *)URL title:(NSString *)title
{
OnsNieuwsAppDelegate *appDelegate = (OnsNieuwsAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate.audioPlayer playAudioAtURL:URL withTitle:title];
}

For the above example, the following assets can be used (button images are white, so hard to see against background):

There's a lot of discussion (and links to blogs, etc.) about singletons over at What should my Objective-C singleton look like?, and I see a fair number of tutorials as a result of this Google search: http://www.google.com/search?q=+cocoa+touch+singleton+tutorial, but the real answer to your question, I believe, is that you should do one of two things:
If you do want the sound for a particular view to continue playing when the user switches, create the player as you're doing now, but when the view (re)appears, check that a player exists, and don't make a new one.
If you want the sound to stop, then stop the sound when the view changes (i.e., in viewWillDisappear:).

UITextField Example in Cocos2d

Can anyone please suggest some links for using UITextField in cocos2d.
I want to press on label, then the UITextField should get selected and I need to edit on that UITextField.
I'm doing this in a current project to allow for entering the number of the level to start playing at, so that's why my variables and methods are named the way they are; you should probably adjust these to make sense for you.
In your app controller, define this as an instance variable:
UITextField *levelEntryTextField;
Create it inside applicationDidFinishLaunching:
levelEntryTextField = [[UITextField alloc] initWithFrame:
CGRectMake(60, 165, 200, 90)];
[levelEntryTextField setDelegate:self];
Define a method to activate the text field. You should also declare it in the header file for your app controller.
- (void)specifyStartLevel
{
[levelEntryTextField setText:#""];
[window addSubview:levelEntryTextField];
[levelEntryTextField becomeFirstResponder];
}
This will make pressing "return" on the keypad end editing
- (BOOL)textFieldShouldReturn:(UITextField*)textField {
//Terminate editing
[textField resignFirstResponder];
return YES;
}
This is triggered when the editing is actually done.
- (void)textFieldDidEndEditing:(UITextField*)textField {
if (textField==levelEntryTextField) {
[levelEntryTextField endEditing:YES];
[levelEntryTextField removeFromSuperview];
// here is where you should do something with the data they entered
NSString *result = levelEntryTextField.text;
}
}
Now to actually set things in motion, you put this somewhere. I call this from within one of my Scene classes, in response to a user action:
[[[UIApplication sharedApplication] delegate] specifyStartLevel];
I took the example that Jack provided and actually created a working project, this was done using the Cocos2D 0.7.1 XCode Template, and then just editting the *AppDelegate.m/.h files, which are provided below in there entirety. I also modified some of what Jack said, because I feel that creating the UITextField in the appDidFinishLoading would utilize a bit too much memory, especially if the text field is not used all the time ... this solution creates the text field only when it is needed, the sample draws an empty Cocos2D Layer scene, and on screen touch, it displays the text field for you to start entering text into. It will spit out the result of what you entered to the Console - you can pass this to whatever is necessary in your own code.
the .h
#import <UIKit/UIKit.h>
#import "cocos2d.h"
#interface MYSCENE : Layer <UITextFieldDelegate>
{
UITextField *myText;
}
-(void)specificStartLevel;
#end
#interface textFieldTestAppDelegate : NSObject <UIAccelerometerDelegate, UIAlertViewDelegate, UITextFieldDelegate, UIApplicationDelegate>
{
UIWindow *window;
}
#end
and then the .m
#import "textFieldTestAppDelegate.h"
#implementation MYSCENE
-(id) init
{
self = [super init];
isTouchEnabled = YES;
return self;
}

}

myText = [[UITextField alloc] initWithFrame:CGRectMake(60, 165, 200, 90)];
[myText setDelegate:self];
[myText setText:#""];
[myText setTextColor: [UIColor colorWithRed:255 green:255 blue:255 alpha:1.0]];
[[[[Director sharedDirector] openGLView] window] addSubview:myText];
[myText becomeFirstResponder];
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField {
[myText resignFirstResponder];
return YES;
}
-(void)textFieldDidEndEditing: (UITextField *)textField {
if(textField == myText) {
[myText endEditing:YES];
[myText removeFromSuperview];
NSString *result = myText.text;
NSLog([NSString stringWithFormat:#"entered: %#", result]);
} else {
NSLog(#"textField did not match myText");
}
}

To add Text field in cocos2d as below code
first of all you add view in Scene and afetr add textfield add in view thats very easy.
-(id) init
{
if( (self=[super init]) )
{
// add view in scene
UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];
view.backgroundColor = [UIColor redColor];
// add textfield in view
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 140, 300, 30)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.placeholder = #"enter text";
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.delegate = self;
[view addSubview:textField];
// add view in scene
[[[CCDirector sharedDirector] view] addSubview:view];
}
return self;
}
you can also use CCTextfield in cocos2d best example is https://github.com/iNinja/CCTextField
Try the following CCNode subclass, CCMenuItemTextField, to use text fields in cocos2d.
The class is directly subclassed from CCMenuItemSprite. When tapped, the "selected" method is called and a UITextField is added to the main window. After editing is done, "unselected" method is called and the UITextField is removed from screen. User's input is saved to a CCLabelTTF node, which position itself exactly as the original UITextField.
