I have gone through many tutorials and believe have done everything, but still can not figure it out, the bannerview does not show ad anytime, I have even put log messages in bannerViewDidLoadAd, didFailToReceiveAdWithError , but those do not get displayed also. Here is the code
I have registered my account in iTunesConnect under monetize, but tax information is pending.Also my app runs only in potrait mode, so no need to handle landscape.
In .h file :
#import <UIKit/UIKit.h>
#import <iAd/iAd.h>
#interface MBViewController : UIViewController <ADBannerViewDelegate>
#property (strong, nonatomic) ADBannerView *bannerView;
#end
In .m file :
- (void)viewDidLoad
{
[super viewDidLoad];
_bannerView = [[ADBannerView alloc] initWithFrame:CGRectZero];
_bannerView.delegate = self;
_bannerView.hidden = YES;
[self.view addSubview:_bannerView];
}
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
NSLog(#"bannerViewDidLoadAd");
CGRect bannerFrame = CGRectMake(0.0, (self.view.frame.size.height - 50), 0.0, 0.0);
[self.bannerView setFrame:bannerFrame];
self.bannerView.hidden = NO;
}
-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
NSLog(#"Error receive ad: %#", error);
self.bannerView.hidden = YES;
}
- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner
willLeaveApplication:(BOOL)willLeave
{
return YES;
}
- (void)bannerViewActionDidFinish:(ADBannerView *)banner
{
}
What about giving a size to your bannerView ?
From your code:
_bannerView = [[ADBannerView alloc] initWithFrame:CGRectZero];
Width = 0, Height = 0
And here you just update the position:
CGRect bannerFrame = CGRectMake(0.0, (self.view.frame.size.height - 50), 0.0, 0.0);
Width = 0, Height = 0
I had the same problem. I ended up going to iTunes Connect, and clicked on the iAd section. Then I agreed to some contract and went to the iAd Workbench area. There, I didn't bother doing anymore because I'm not at the point where I want to advertise the game I'm developing yet.
I didn't change any code, but my iOS game was still running. To my surprise, the ads started to show up right after I agreed to the iAd agreement in iTunes Connect!

All,
I want to add UISearchBar to UINavigationbar, I dont dont want to use UISearchController, Just UISearchbar programmatically and it must work in landscape as well.
I tried it is working well in Portrait well, but in Landscape, i have issues in iPhone X width. Can we use Constraints.
Below is the code
CGFloat width = [UIScreen mainScreen].bounds.size.width;
search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, width - 2 * 44 - 2 * 15, 44)];
search.delegate = self; // search.tintColor = [UIColor redColor];
search.searchBarStyle = UISearchBarStyleMinimal;
search.placeholder = #"Search";
search.translucent = NO;
search.opaque = NO;
search.showsCancelButton = NO;
[search setBackgroundImage:[[UIImage alloc] init]];
//customize textfield inside UISearchBar
#try {
for (id object in [[[search subviews] firstObject] subviews])
{
if (object && [object isKindOfClass:[UITextField class]])
{
UITextField *textFieldObject = (UITextField *)object;
textFieldObject.backgroundColor = [UIColor whiteColor];
textFieldObject.borderStyle = UITextBorderStyleRoundedRect;
textFieldObject.layer.borderColor = (__bridge CGColorRef _Nullable)([brandingObj getValueForKey:navBarTitleColor]);
textFieldObject.layer.borderWidth = 1.0;
break;
}
}
}
#catch (NSException *exception) {
NSLog(#"Error while customizing UISearchBar");
}
#finally {
}
I don't understand why you want to use UISearchDisplayController, its highly configurable and recommended by apple, working with geometry (CGRecr, CGFrame, etc.) to adjust UIKit objects layout could be a pain, use auto layout avoiding UIKits convenience initializers, to adjust later constraints.
Anyway if you want explicitly do with this way, this should work.
#import "ViewController.h"
#interface ViewController ()<UISearchBarDelegate>
#property UISearchBar *searchbar;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
_searchbar = [UISearchBar new];
_searchbar.delegate = self;
_searchbar.searchBarStyle = UISearchBarStyleMinimal;
self.navigationItem.titleView = self.searchbar;
// Do any additional setup after loading the view, typically from a nib.
}
Maybe you should need configure appearance , take a look here
Cheers.
I have a UITextView where the user can create notes and save into a plist file.
I want to be able to show lines just like a normal notebook. The problem I have is
that the text won't align properly.
The image below explains the problem quite well.
This is the background I use to create the lines like the Notes.app
This is my code for creating the background for my UITextView:
textView.font = [UIFont fontWithName:#"MarkerFelt-Thin" size:19.0];
textView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed: #"Notes.png"]];
I know that the UIFont.lineHeight property is only available in > iOS 4.x.
So I wonder if there is another solution to my problem?
You should try and draw your lines programmatically rather than using an image. Here's some sample code of how you could accomplish that. You can subclass UITextView and override it's drawRect: method.
NoteView.h
#import <UIKit/UIKit.h>
#interface NoteView : UITextView <UITextViewDelegate> {
}
#end
NoteView.m
#import "NoteView.h"
#implementation NoteView
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.backgroundColor = [UIColor colorWithRed:1.0f green:1.0f blue:0.6f alpha:1.0f];
self.font = [UIFont fontWithName:#"MarkerFelt-Thin" size:19];
}
return self;
}
- (void)drawRect:(CGRect)rect {
//Get the current drawing context
CGContextRef context = UIGraphicsGetCurrentContext();
//Set the line color and width
CGContextSetStrokeColorWithColor(context, [UIColor colorWithRed:0.0f green:0.0f blue:0.0f alpha:0.2f].CGColor);
CGContextSetLineWidth(context, 1.0f);
//Start a new Path
CGContextBeginPath(context);
//Find the number of lines in our textView + add a bit more height to draw lines in the empty part of the view
NSUInteger numberOfLines = (self.contentSize.height + self.bounds.size.height) / self.font.leading;
//Set the line offset from the baseline. (I'm sure there's a concrete way to calculate this.)
CGFloat baselineOffset = 6.0f;
//iterate over numberOfLines and draw each line
for (int x = 0; x < numberOfLines; x++) {
//0.5f offset lines up line with pixel boundary
CGContextMoveToPoint(context, self.bounds.origin.x, self.font.leading*x + 0.5f + baselineOffset);
CGContextAddLineToPoint(context, self.bounds.size.width, self.font.leading*x + 0.5f + baselineOffset);
}
//Close our Path and Stroke (draw) it
CGContextClosePath(context);
CGContextStrokePath(context);
}
#end
MyViewController.h
#import <UIKit/UIKit.h>
#import "NoteView.h"
#interface MyViewController : UIViewController <UITextViewDelegate> {
NoteView *note;
}
#property (nonatomic, retain) NoteView *note;
#end
MyViewController.m
#import "MyViewController.h"
#import "NoteView.h"
#define KEYBOARD_HEIGHT 216
#implementation MyViewController
#synthesize note;
- (void)loadView {
[super loadView];
self.note = [[[NoteView alloc] initWithFrame:self.view.bounds] autorelease];
[self.view addSubview:note];
note.delegate = self;
note.text = #"This is the first line.\nThis is the second line.\nThis is the ... line.\nThis is the ... line.\nThis is the ... line.\nThis is the ... line.\nThis is the ... line.\n";
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
[note setNeedsDisplay];
}
- (void)textViewDidBeginEditing:(UITextView *)textView {
CGRect frame = self.view.bounds;
frame.size.height -= KEYBOARD_HEIGHT;
note.frame = frame;
}
- (void)textViewDidEndEditing:(UITextView *)textView {
note.frame = self.view.bounds;
}
- (void)dealloc {
[note release];
[super dealloc];
}
Take a look at Apple's documentation for Managing the Keyboard, specifically "Moving Content That Is Located Under the Keyboard". It explains how to listen for NSNotifcations and adjust your views properly.
I think the problem is with your image, the yellow space over the line is creating the problem.
You should edit the image.
And nice work.
When i try to add ATMHud to uitableviewcontroller subview it does work but it doesn't disable the scrolling and if the tableview is not on top i can't see the hud view. What i did was added to teh tabBarController.view that works but i want find out if this is a good idea or later on i might have issues with it.
Another question is tabBarController.view frame is that the whole screen or just the bottom part. How come atmhud shows in the middle of the screen?
Thanks in advance!
Yan
============
Found a blog post that shows how to reset self.view and add tableview separately in uitableviewcontroller
UITableViewController and fixed sub views
- (void)viewDidLoad {
[super viewDidLoad];
if (!tableView &&
[self.view isKindOfClass:[UITableView class]]) {
tableView = (UITableView *)self.view;
}
self.view = [[[UIView alloc] initWithFrame:
[UIScreen mainScreen].applicationFrame] autorelease];
self.tableView.frame = self.view.bounds;
self.tableView.contentInset = UIEdgeInsetsMake(44.0, 0.0, 0.0, 0.0);
[self.view addSubview:self.tableView];
UIView *fixedBar = [[UIView alloc] initWithFrame:
CGRectMake(0.0, 0.0, self.view.bounds.size.width, 44.0)];
fixedBar.backgroundColor = [UIColor colorWithRed:
0.0 green:1.0 blue:0.0 alpha:0.7];
[self.view addSubview:fixedBar];
[fixedBar release];
}
After this when add hud to self.view you will be able to disable the tableview on the bottom.
Let me know if this a good way to setup the tableview
The problem with using the tab bar is that the hud is now modal, and the user cannot change the tab.
It sounds like the tableview is not your primary viewm, as it can get "covered up". If its not the primary view, then add the ATMHud to self.view. If the tableView is the same as self.view, then add a new transparent view to it, then add the HUD to that view.
The tabBarController.view is the view that hosts the tabbed views - if you want to see its size (or frame) log it using NSStringFromCGRect(self.tabBarController.frame);
EDIT: I just did a test, the ATMHud DOES block the UI. All I can think of is that you have not inserted it where you need to (at the top of current view's subviews.) I have a demo project where I do this:
hud = [[ATMHud alloc] initWithDelegate:self];
[self.view addSubview:hud.view];
[hud setCaption:#"Howdie"];
[hud setActivity:YES];
[hud show];
[hud hideAfter:5];
A button under the hud is not active - in fact nothing in the view is active (probably the Nav Bar would be live though)
If you want an ARCified and field tested version, you can grab it here
EDIT2: The solution to your problem is below. Note that ATMHud blocks clicks from getting to the table, and the code below stops the scrolling:
- (void)hudWillAppear:(ATMHud *)_hud
{
self.tableView.scrollEnabled = NO;
}
- (void)hudDidDisappear:(ATMHud *)_hud
{
self.tableView.scrollEnabled = YES;
}
Dump the views:
#import <QuartzCore/QuartzCore.h>
#import "UIView+Utilities.h"
#interface UIView (Utilities_Private)
+ (void)appendView:(UIView *)v toStr:(NSMutableString *)str;
#end
#implementation UIView (Utilities_Private)

[str appendFormat:#" %#: frame=%# bounds=%# layerFrame=%# tag=%d userInteraction=%d alpha=%f hidden=%d\n",
NSStringFromClass([a class]),
NSStringFromCGRect(a.frame),
NSStringFromCGRect(a.bounds),
NSStringFromCGRect(a.layer.frame),
a.tag,
a.userInteractionEnabled,
a.alpha,
a.isHidden
];
}
#end
#implementation UIView (Utilities)
+ (void)dumpSuperviews:(UIView *)v msg:(NSString *)msg
{
NSMutableString *str = [NSMutableString stringWithCapacity:256];
while(v) {
[self appendView:v toStr:str];
v = v.superview;
}
[str appendString:#"\n"];
NSLog(#"%#:\n%#", msg, str);
}
+ (void)dumpSubviews:(UIView *)v msg:(NSString *)msg
{
NSMutableString *str = [NSMutableString stringWithCapacity:256];
if(v) [self appendView:v toStr:str];
for(UIView *a in v.subviews) {
[self appendView:a toStr:str];
}
[str appendString:#"\n"];
NSLog(#"%#:\n%#", msg, str);
}
#end
In my TestApp, I created a class "Carousel" which should let me create a swipe menu with a UIPageControl in an easy way (by simply creating an instance of the class Carousel).
Carousel is a subclass of UIView
At init, it creates an UIView, containing UIScrollView, UIPageControl
I can add further UIViews to the scroll view
I don't know if this is the proper way to do it, but my example worked quite well in my TestApp. Swiping between pages works perfectly and the display of the current page in the UIPageControl is correct.
If there were not one single problem: The UIPageControl sometimes reacts to clicks/taps (I only tested in Simulator so far!), sometimes it doesn't. Let's say most of the time it doesn't. I couldn't find out yet when it does, for me it's just random...
As you can see below, I added
[pageControl addTarget:self action:#selector(pageChange:) forControlEvents:UIControlEventValueChanged];
to my code. I thought this would do the proper handling of taps? But unfortunately, pageChange doesn't get always called (so the value of the UIPageControl doesn't change every time I click).
I would appreciate any input on this because I couldn't find any solution on this yet.
This is what I have so far:
Carousel.h
#import <UIKit/UIKit.h>
#interface Carousel : UIView {
UIScrollView *scrollView;
UIPageControl *pageControl;
BOOL pageControlBeingUsed;
}
- (void)addView:(UIView *)view;
- (void)setTotalPages:(NSUInteger)pages;
- (void)setCurrentPage:(NSUInteger)current;
- (void)createPageControlAt:(CGRect)cg;
- (void)createScrollViewAt:(CGRect)cg;
#end
Carousel.m
#import "Carousel.h"
#implementation Carousel
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
// Create a scroll view
scrollView = [[UIScrollView alloc] init];
[self addSubview:scrollView];
scrollView.delegate = (id) self;
// Init Page Control
pageControl = [[UIPageControl alloc] init];
[pageControl addTarget:self action:#selector(pageChange:) forControlEvents:UIControlEventValueChanged];
[self addSubview:pageControl];
}
return self;
}
- (IBAction)pageChange:(id)sender {
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * pageControl.currentPage;
frame.origin.y = 0;
[scrollView scrollRectToVisible:frame animated:TRUE];
NSLog(#"%i", pageControl.currentPage);
}
- (void)addView:(UIView *)view {
[scrollView addSubview:view];
}
- (void)createPageControlAt:(CGRect)cg {
pageControl.frame = cg;
}
- (void)setTotalPages:(NSUInteger)pages {
pageControl.numberOfPages = pages;
}
- (void)setCurrentPage:(NSUInteger)current {
pageControl.currentPage = current;
}
- (void)createScrollViewAt:(CGRect)cg {
[scrollView setPagingEnabled:TRUE];
scrollView.frame = cg;
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width*pageControl.numberOfPages, scrollView.frame.size.height);
[scrollView setShowsHorizontalScrollIndicator:FALSE];
[scrollView setShowsVerticalScrollIndicator:FALSE];
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
float frac = scrollView.contentOffset.x / scrollView.frame.size.width;
NSUInteger page = lround(frac);
pageControl.currentPage = page;
}
#end
ViewController.m (somewhere in viewDidLoad)
Carousel *carousel = [[Carousel alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
for (int i=0; i<5; i++) {
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(i * 320, 0, 320, 420)];
UIColor *color;
if(i%3==0) color = [UIColor blueColor];
else if(i%3==1) color = [UIColor redColor];
else color = [UIColor purpleColor];
view.backgroundColor = color;
[carousel addView:view];
view = nil;
}
[carousel setTotalPages:5];
[carousel setCurrentPage:0];
[carousel createPageControlAt:CGRectMake(0,420,320,40)];
[carousel createScrollViewAt:CGRectMake(0,0,320,420)];
Your code is correct. Most likely the frame of your pageControl is pretty small, so theres not a lot of area to look for touch events. You would need to increase the size of the height of pageControl in order to make sure taps are recognized all of the time.
I'm looking for some guidance on the best way to implement stock ticker style right-to-left scrolling of CALayers in Core Animation on OSX. I'm pretty new to Cocoa and don't know the best way to implement this.
I have a continuous stream of news items and stock details that I turn into CALayers (made up of 1 image and a CATextLayer) and I want to animate the CALayers from right to left of my custom view.
The news and stock information is constantly updating so I would like to add 1 item at a time to the view, scroll it right to left until the right-most point of the CALayer is showing, then add another CALayer to the view and start scrolling that as well. I would like to do this dynamic updating instead of taking a big snapshot of all my data, turning it into a big horizontal CALayer and scrolling that.
I'm looking for guidance on how to achieve this sort of effect -
do I manually animate each new CALayer along a path in the view? Or should I be using CAScrollLayer to achieve this effect?
Many thanks
Glen.
I'd do this with Quartz Composer and put a QCView in your app. It's a lot less work than you imagine.
You perhaps don't need to customize anything to do this. Here self is an object of class extending UIScrollView and with a UILabel to display the text.
