On iPhone all ok. On iPads iAds ads looks like corrupted. But when it loads new ads (blue, red etc..) all looks great. Where is my mistake?
// in applicationDidFinishLaunchingWithOptions
CGSize winSize = [[CCDirector sharedDirector] viewSize];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
adsBanner = [[ADBannerView alloc] initWithFrame:CGRectMake(0, winSize.height - 66, 768, 66)];
}
else
{
adsBanner = [[ADBannerView alloc] initWithFrame:CGRectMake(0, winSize.height - 50, 320, 50)];
}
// somewhere in AppDelegate
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
[self.window.rootViewController.view addSubview:banner];
}
Here is image from iPad with corrupted ads:
Your question has nothing to do with iPad. Why are you initializing the ADBannerView like this? You are not using the API correctly. Use the designated initializer method initWithAdType: to get the correct result (you most likely need to use ADAdTypeBanner as the type).
To resize to fit to a specific view, you need to use what is recommended here.

In iOS 7 my app presented an authentication screen when the app went into the background (by subscribing to UIApplicationDidEnterBackgroundNotification). The authentication controller removed sensitive information so the background screenshot did not show any user info. In iOS 8 this does not work anymore. The background screenshot now shows the view the user was last working in and not the authentication controller... even though when the app comes back into the foreground the authentication controller is active.
I found a work around for now. Instead of using UIApplicationDidEnterBackgroundNotification I can use name:UIApplicationWillResignActiveNotification however this causes a flash as the user leaves the app.
Is this a bug or did apple provide a new way to remove sensitive information from views before moving to the background.
Note: putting ignoreSnapshotOnNextApplicationLaunch in applicationWillResignActive:
and applicationDidEnterBackground: did not help.
Update: created a bug report
Similar approach to #Gurudev0777, but uses UIBlurEffect instead to obscure the content, and doesn't have the downside of worrying about different device screen metrics. Application delegate:
#define MY_BACKGROUND_SCREEN_TAG 1001//or any random but UNIQUE number.
- (void)applicationDidEnterBackground:(UIApplication *)application
{
// Visual effect view for blur
UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView *blurView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
[blurView setAutoresizingMask:(UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight)];
[blurView setFrame:self.window.frame];
blurView.tag = MY_BACKGROUND_SCREEN_TAG;
[self.window addSubview:blurView];
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
// remove blur view if present
UIView *view = [self.window viewWithTag:MY_BACKGROUND_SCREEN_TAG];
if (view != nil)
{
[UIView animateWithDuration:0.2f animations:^{
[view setAlpha:0];
} completion:^(BOOL finished) {
[view removeFromSuperview];
}];
}
}
works like a charm...
Edited 5/18/2015: Thanks #Simeon Rice for observation about modal dialogs, revised to add blur view to self.window instead of rootViewController.view
Edited 8/23/2016: Thanks #tpankake for observation re: auto-resizing mask.
- (void)applicationWillResignActive:(UIApplication *)application
{
// show splash when app goto background
UIImageView *imageView = [[UIImageView alloc] initWithFrame:self.window.bounds];
imageView.tag = 101; // assign image tag
// imageView.backgroundColor = [UIColor redColor];
[imageView setImage:[UIImage imageNamed:#"Default.png"]];
[UIApplication.sharedApplication.keyWindow.subviews.lastObject addSubview:imageView];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// remove splash when app goto foreground
UIImageView *imageView = (UIImageView *)[UIApplication.sharedApplication.keyWindow.subviews.lastObject viewWithTag:101]; // lookup image by image tag
[imageView removeFromSuperview];
}
here we are putting an imageview while the app animate to background -
-(void)applicationWillResignActive:(UIApplication *)application
{
imageView = [[UIImageView alloc]initWithFrame:[self.window frame]];
[imageView setImage:[UIImage imageNamed:#"Default#2x.png"]];
[self.window addSubview:imageView];
}
Here is the code to remove the imageview:
- (void)applicationDidBecomeActive:(UIApplication *)application
{
if(imageView != nil) {
[imageView removeFromSuperview];
imageView = nil;
}
}
It is working and tested many times.
*** Please test this scenario into the device not in simulator.
I have a problem with modalviewcontrollers that I want to represent on iPad screen. If I leave the size as it is, then it's all centred fine. But I have very few info on these views, so I need to resize them.
So, when I resize them, I can't force them to appear in the middle of the screen. Even if I manage to center one of them in one orientation, it's messed up in other one.
Here is my current code:
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:acvc];
[nav setModalPresentationStyle:UIModalPresentationFormSheet];
[nav setModalTransitionStyle: UIModalTransitionStyleCoverVertical];
[[acvc view] setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"main_bg.jpg"]]];
[self presentViewController:nav animated:YES completion:nil];
nav.view.superview.frame = CGRectMake(self.view.bounds.size.width/2 + 175, self.view.bounds.size.height/2 - 125, 350, 250);
// nav.view.superview.center = self.view.window.center;
Would appreciate any help, thank you.
Here's a method that works on iOS7 as well as iOS6 and iOS5 and still allows you to use UIModalTransitionStyleCoverVertical:
-(void)presentController:(UIViewController*)controller fromRootController:(UIViewController*)rootController withSize:(CGSize)size
{
UINavigationController* nav = [[UINavigationController alloc] initWithRootViewController:controller];
nav.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
nav.modalPresentationStyle = UIModalPresentationFormSheet;
[rootController presentModalViewController:nav animated:YES];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)
{
nav.view.superview.backgroundColor = [UIColor clearColor];
nav.view.bounds = CGRectMake(0, 0, size.width, size.height);
}
else
{
nav.view.superview.bounds = CGRectMake(0, 0, size.width, size.height);
}
}
Change your last line to the following:
nav.view.superview.bounds = CGRectMake(0, 0, 350, 250);
Stopped working in iOS7, unfortunately.
Only changing ModalTransitionStyle to Dissolve solves the problem. Maybe it's a bug in iOS 7...
in ios 7 you can use :
- (void)viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
self.view.superview.bounds = CGRectMake(0, 0, width, height);
}
it works.
My client wants his splash image to fade out and then show the UI. I am not sure how to do this. As of right now it just appears once it loads. Is there a simple way to do this ?
UIImageView *splash=[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"splash"]];
[UIView animateWithDuration:1
animations:^{
splash.alpha = 0.0;
}
completion:^(BOOL finished)
{
[splash release];
}];
I was looking at this tutorial but decided not to implement it so I cant vouch as to whether it works or not but everything looks in check
http://www.dobervich.com/2010/10/22/fade-out-default-ipad-app-image-with-proper-orientation/
Beware though adding to much to your app startup is grounds for app rejection.
Avoid displaying an About window or a splash screen. In general, try
to avoid providing any type of startup experience that prevents people
from using your application immediately.

As I just explained on a closely related question, don't use splash screens! Please relate this to your client, who might not be familiar with the Human Interface Guidelines.
That said, if you can't convince you client otherwise, you can just fade out the UIImageView that I mentioned in my other response.
You can implement your own UIViewController as a splash screen:
#interface SplashScreenViewController : UIViewController {
UIImageView *splashView;
}
#end
//
#import "SplashScreenViewController.h"
#implementation SplashScreenViewController
#pragma mark - View lifecycle
- (void)loadView {
self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[splashView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
[self.view addSubview:splashView];
}
- (void)viewWillAppear:(BOOL)animated {
if (isIPad) {
if (UIInterfaceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation]))
splashView.image = [UIImage imageNamed:#"Default-Portrait~ipad.png"];
else
splashView.image = [UIImage imageNamed:#"Default-Landscape~ipad.png"];
}
else
splashView.image = [UIImage imageNamed:#"Default.png"];
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if (isIPad) {
if (UIInterfaceOrientationIsPortrait(toInterfaceOrientation))
splashView.image = [UIImage imageNamed:#"Default-Portrait~ipad.png"];
else
splashView.image = [UIImage imageNamed:#"Default-Landscape~ipad.png"];
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (isIPad ? YES : UIInterfaceOrientationIsPortrait(interfaceOrientation));
}
#end
Then, after showing, you can hide this UIViewController with any transition you want.
I have a simple app that is targeting iPad and iOS 5+ only. The app is landscape-only. Now, I want to take advantage of AirPlay mirroring on the iPad 2.
I have followed all of Apple's examples/documentation I can find and can't get past this drawing problem. The secondary display doesn't draw in the correct orientation.
Below is the output I am seeing from a small test app. The blue box is just a simple UIView that should be taking up the entire screen, but is not. It seems to be drawing correctly in landscape, but the view is rotated 90 degrees. Notice how the blue extends past the margin on the bottom of the TV:
I think I need to somehow force the ViewController of the external window to correctly draw in landscape, but I don't know the proper way to do this. Any ideas?
Below are the relevant pieces code:
AppDelegate.m:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(screenDidConnect:)
name:UIScreenDidConnectNotification
object:nil];
[self initScreens];
return YES;
}
- (void)screenDidConnect:(NSNotification *)note
{
[self initScreens];
}
- (void)initScreens
{
if ([[UIScreen screens] count] > 1)
{
UIScreen *screen = [[UIScreen screens] lastObject];
if (!self.secondaryWindow)
{
self.secondaryWindow = [[UIWindow alloc] initWithFrame:screen.bounds];
self.secondaryWindow.screen = screen;
self.secondaryWindow.hidden = NO;
}
if (!self.secondaryViewController)
{
self.secondaryViewController = [[CCKSecondaryViewController alloc] init];
}
self.secondaryWindow.rootViewController = self.secondaryViewController;
}
}
CCKSecondaryViewController.m: This is the rootViewController of the external window
- (void)loadView
{
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
view.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
view.backgroundColor = [UIColor blueColor];
self.view = view;
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.text = #"Secondary Screen";
[label sizeToFit];
[self.view addSubview:label];
label.center = self.view.center;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
You can find the sample app here:
http://dl.dropbox.com/u/360556/AirplayTest.zip
It's displaying in portrait on the connected screen. Having your shouldAutorotateToInterfaceOrientation method always return NO should sort it out for you.
I am interested to know on how I can resize the view when using UIModalPresentationFormSheet of modalPresentationStyle, it looks like it has a fixed size so I was wondering if anyone out there did managed to manipulate the popup view from the sizing perspective.
So there is either UIModalPresentationFormSheet with a fixed view size or full views and I am after something in between.
MyModalViewController *targetController = [[[MyModalViewController alloc] init] autorelease];
targetController.modalPresentationStyle = UIModalPresentationFormSheet;
targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:targetController animated:YES];
// it is important to do this after presentModalViewController:animated:
targetController.view.superview.bounds = CGRectMake(0, 0, 200, 200);
You are able to adjust the frame of a modal view after presenting it:
Tested in iOS 5.1 - 6.1, using XCode 4.62
MyModalViewController *targetController = [[[MyModalViewController alloc] init] autorelease];
targetController.modalPresentationStyle = UIModalPresentationFormSheet;
targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; //transition shouldn't matter
[self presentModalViewController:targetController animated:YES];
targetController.view.superview.frame = CGRectMake(0, 0, 200, 200);//it's important to do this after presentModalViewController
targetController.view.superview.center = GPointMake(roundf(self.view.center.x), roundf(self.view.center.y));//self.view assumes the base view is doing the launching, if not you might need self.view.superview.center etc.
Update The preferred iOS 6.0 view controller presentation method also works correctly:
- (void)presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion
In ios8 and earlier works:
AboutViewController * _aboutViewController = [[AboutViewController alloc] init];
_aboutViewController.modalPresentationStyle = UIModalPresentationFormSheet;
if(IS_IOS8)
{
_aboutViewController.preferredContentSize = CGSizeMake(300, 300);
}
[self presentViewController:_aboutViewController animated:YES completion:nil];
In AboutViewController.m
- (void)viewWillLayoutSubviews{
[super viewWillLayoutSubviews];
if(!IS_IOS8)
{
self.view.superview.bounds = CGRectMake(0, 0, 300, 300);
}
}
IS_IOS8
#define IS_IOS8 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8)
In iOS 8 you can also use UIPresentationController which gives you more customization options.
For iOS 8, simply implement the delegate method (CGSize)preferredContentSize on each view controller. It should resolve all the size issue.
Just to extent Fatos solution (great one)
If your are creating the view controller using a .xib file after the alloc initWithNibName you could store the view frame:
CGRect myFrame = targetController.view.frame;
...
targetController.view.superview.bounds = myFrame;
And then use it for superview.bounds, so the view's size in the .xib will be used and you could change the size more visually.
I put this code in the form sheet view controller:
-(void) viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
self.view.superview.bounds = CGRectMake(0, 0, 540, 500); // your size here
}
Note that the resizing occurs early enough that the the presentation animation looks correct.
