Hi Guys What Do You Think Should I Use In The Handle Notifications (hideAd,showAd) to show and hide my iAd Banner In My Project and here is what i use to show iAd Banner `#import "GameViewController.h"
import "GameScene.h"
#interface GameViewController(){
bool adOnTop;
bool iadsBannerIsVisible;
ADBannerView* theBanner;
}
#end
#implementation GameViewController

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.
i have tried below code. As result its gets image some time, not in every call of this method.
is there any solution.
-(UIImage *)thumbnailFromVideoAtURL:(NSString *)urlstr
{
NSURL *url = [NSURL URLWithString:urlstr];
AVAsset *asset = [AVAsset assetWithURL:url];
// Get thumbnail at the very start of the video
CMTime thumbnailTime = [asset duration];
thumbnailTime.value = 0;
// Get image from the video at the given time
AVAssetImageGenerator *imageGenerator = [[AVAssetImageGenerator alloc] initWithAsset:asset];
CGImageRef imageRef = [imageGenerator copyCGImageAtTime:thumbnailTime actualTime:NULL error:NULL];
UIImage *thumbnail = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef);
return thumbnail;

Use getVideoThumbnail to get image from video.
My question is :
When I write a user login UI, because the keyboard hide the password textfield, so I write some code to scroll up the login UI, but when the keyboard is hidden and the UI is scrolled to the old position, I find I touch the textfield which I can't get any response.
registe notification:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillshow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillhide:)
name:UIKeyboardWillHideNotification
object:nil];
_username.delegate = self;
_password.delegate = self;
will show keyboard code:
- (void) keyboardWillshow:(NSNotification *)noti
{
NSDictionary *userInfo = [noti userInfo];
NSValue *keyValue = [userInfo objectForKey:UIKeyboardFrameEndUserInfoKey];
CGRect keyboardRect = [keyValue CGRectValue];
int height = keyboardRect.size.height;
userInfo = nil;
keyValue = nil;
[UIView animateWithDuration:0.5f animations:^{
self.containView.frame = CGRectMake(0, -height+20, WIDTH/2, HEIGHT/2-20);
}];
}
will hide keyboard code:
- (void)keyboardWillhide:(NSNotification *)noti
{
[UIView animateWithDuration:0.5f animations:^{
self.containView.frame = CGRectMake(0, 20, WIDTH/2, HEIGHT/2-20);
}];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[_password resignFirstResponder];
[_username resignFirstResponder];
}
Could some one help me? I use the storyboard to write the code.
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;

}

{

}
return self;
}
- (void)loadView
{
UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[contentView addSubview:_bannerView];
[self addChildViewController:_contentController];
[contentView addSubview:_contentController.view];

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;
}

#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.
I have a small project that contains a few UITextFields with a number keypad. When the keyboard is displayed I'm adding a button as a subview for the user to dismiss the keyboard.
However, if the keyboard is active and I close the application, the button I've added will disappear upon relaunching the app. (The app stays inactive, through multitasking, and therefore not quit completely.)
This is the code im using to add the button (my "done" button configured in the xib).
- (void)viewDidLoad

[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow)name:UIKeyboardWillShowNotification object:nil];

// Add the button to foundKeyboard.
}

i think your problem because you are removing the observer in the - (void)keyboardWillShow .. try to put this line [[NSNotificationCenter defaultCenter] removeObserver:self]; in the -(void)viewDidUnload
