I am trying to create a shared iADBannerView across multiple View Controllers in a Tabbed Application. I have tried different ways to create this, including Apple's iAdSuite but have been unsuccessful.
Currently with my code, which works but I have received errors such as:
"The operation couldn’t be completed. Ad was unloaded from this banner"
App Delegate .h
#import <iAd/iAd.h>
#interface AppDelegate : UIResponder <ADBannerViewDelegate>{
BOOL bannerIsVisible;
}
#property BOOL bannerIsVisible;
#property (nonatomic, strong) ADBannerView *adView;
App Delegate .m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
return YES;
}
View Controller .m
- (void)viewDidLoad
{
...
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
appDelegate.adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
appDelegate.adView.delegate = self;
appDelegate.adView.frame = CGRectOffset(appDelegate.adView.frame, 0, self.view.frame.size.height);
[appDelegate.adView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[self.view addSubview:appDelegate.adView];
appDelegate.bannerIsVisible = NO;
}
-(void)bannerViewDidLoadAd:(ADBannerView *)banner
{
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
if (!appDelegate.bannerIsVisible){
[UIView beginAnimations:#"animateAdBannerOn" context:NULL];
banner.frame = CGRectOffset(banner.frame, 0, -50);
[UIView commitAnimations];
appDelegate.bannerIsVisible = YES;
}
}
-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
if (appDelegate.bannerIsVisible){
[UIView beginAnimations:#"animateAdBannerOff" context:NULL];
banner.frame = CGRectOffset(banner.frame, 0, 50);
[UIView commitAnimations];
appDelegate.bannerIsVisible = NO;
}
}
If anyone has implemented shared iAds, help would be appreciated, thanks in advance!
Edit: Found a solution by following this video
This is possible, all you have to do is make a master UIViewController with the ad and then use a container view controller with the Tab stuff. See the following links:
Apple documentation on container views:
https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/CreatingCustomContainerViewControllers/CreatingCustomContainerViewControllers.html
This is an awesome library that does all the management for you.

I use keyWindow to add a subView, it add success but did not shows in the front of the screen hierarchy.
The deep gray view is my added view:
My code is:
#interface ViewController ()
{
LMLUpspringView *pop_v;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
pop_v = [[LMLUpspringView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
UIWindow *keywindow = [[[UIApplication sharedApplication] delegate] window];
[keywindow addSubview:pop_v];
//[keywindow bringSubviewToFront:pop_v];
//[self.view addSubview:pop_v];
}
I have tried use [keywindow bringSubviewToFront:pop_v] to bring to front.But do not work.
And if I use [self.view addSubview:pop_v], it shows in the front.
You run into this issue, is caused by you do not know the difference between the viewDidLoad method and the viewDidAppear: method.
viewWillAppear:
Called before the view is added to the windows’ view hierarchy
viewDidAppear:
Called after the view is added to the view hierarchy
The controller's view add to the window's view hierarchy is betweenviewWillAppear: and viewDidAppear:, the viewDidLoad is in front of viewWillAppear:, so you can not do that. you should in viewDidAppear: add your view.
You can solve this problem using appdelegate's Windows :
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate.window addSubview:pop_v]
Use this:
#interface ViewController ()
{
LMLUpspringView *pop_v;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
pop_v = [[LMLUpspringView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
UIWindow *keywindow = [[UIApplication sharedApplication] keyWindow];
[keywindow addSubview:pop_v];
//[keywindow bringSubviewToFront:pop_v];
//[self.view addSubview:pop_v];
}
I've been developing for iOS for quite a while now, but I always got problems with custom alerts / popups, I just don't know what is the right way to add a custom view as a popup on top of all other views in app.
I've checked online and there are several ways to do it, but what is the best way for creating those custom alerts / popups?
There is a CustomViewController class and this is how I've created it and add it as a popup:
Create a new UIViewController
Add a UIView inside the UIViewController's XIB file as a child of self.view (This will hold the popup elements inside)
Add this method inside the UIViewController for presenting the view:
- (void)presentViewController
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.windowLevel = UIWindowLevelStatusBar;
self.window.screen = [UIScreen mainScreen];
[self.window makeKeyAndVisible];
UIWindow *mainWindow = [[[UIApplication sharedApplication] delegate] window];
[mainWindow setUserInteractionEnabled:NO];
[self.window addSubview:self.view];
self.view.alpha = 0.0f;
self.backgroundImage.image = [self takeSnapshot];
[UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
self.view.transform = CGAffineTransformIdentity;
self.view.alpha = 1.0f;
} completion:nil];
}
Add this method inside the UIViewController for removing the view:
- (void)dismissShareViewController
{
[UIView animateWithDuration:DEFAULT_ANIMATION_DURATION
animations:^{
self.view.alpha = 0.0f;
} completion:^(BOOL finished) {
[self.view removeFromSuperview];
self.window = nil;
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
UIWindow *mainWindow = [[[UIApplication sharedApplication] delegate] window];
[mainWindow setUserInteractionEnabled:YES];
}];
}
Usage:
Creating a property for the UIViewController
#property (strong, nonatomic) CustomViewController *viewController;
Initialize and present
- (void)showCustomViewController
{
self.viewController = [[CustomViewController alloc] init];
[self.viewController presentViewController];
}
The problem is that I always get a Received Memory Warning. Also I've added a - (void)dealloc method inside the CustomViewController to know if the UIViewController is releasing properly, but for some reason the dealloc method is getting called right after the presentViewController and not after the dismissShareViewController as it should.
Another thing that I want to achieve: This CustomViewController has no UIStatusBar and when I try to present MFMailComposeViewController, I always get the MFMailComposeViewController to show without a UIStatusBar or with white status bar, but I can't change it to default back again. I've tried several question here on StackOverflow but without any luck, it just won't change.
Putting a UIView or UIWindow above Statusbar
Please, for once and for all, someone will help me with it.
UIAlertView is a subclass of UIView. If you wanted to create a custom alert view, I would also subclass UIView so that it is easy to swap out your existing UIAlertView's with your new custom view.
You can place your custom alert view atop your topmost UIWindow to cover everything.
#interface MyAlertView : UIView
- (void)duplicateAllTheFunctionsOfUIAlertViewHere;
#end
#implementation MyAlertView : UIView
- (id)initWithFrame:(CGRectMake)frame {
// add your custom subviews here
// An example of a custom background color:
self.backgroundColor = [UIColor colorWithRed:1.0 green:0.0 blue:0.0 alpha:0.5];
}
- (void)duplicateAllTheFunctionsOfUIAlertViewHere {
//re-implement all the functionality in your custom ways
}
- (void)show
{
UIView* superview = [UIApplication sharedApplication].keyWindow;
self.frame = superview.bounds;
[superview addSubview:self];
// Do an animation if you want to get fancy
}
#end
Usage in a view controller:
- (void)showAlertView
{
UIView* alertView = [[MyAlertView alloc] initWithTextAndButtons:#"blah"];
[alertView show];
}
I have a project that starts off with a tableView, however when the user taps the Setup button, I want to animate the change to a splitViewController.
I can easily change the rootViewController, however the animation isn't as advertised:
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"SetupViewController"];
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[UIView transitionWithView:self.navigationController.view
duration:0.75
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^{
app.window.rootViewController = controller;
}
completion:nil];
Is there a way I can animate this change of rootViewController?
It is a little hackie, but try setting the root before the animation and back again, so the new ViewController gets the right size when you start the animation:
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"SetupViewController"];
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
UIViewController *currentController = app.window.rootViewController;
app.window.rootViewController = controller;
app.window.rootViewController = currentController;
[UIView transitionWithView:self.navigationController.view.window
duration:0.75
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^{
app.window.rootViewController = controller;
}
completion:nil];
This solution worked for me.
I have two xib files and for each it's own class which overrides UIViewController class. I have a button in first xib file which should take me to new UIViewController when it's pressed. I have managed to make that transition in different ways:
UIViewController* secondViewController = [[UIViewController alloc] initWithNibName:#"SecondViewControllerName" bundle:[NSBundle mainBundle]];
[self.view addSubview:secondViewController.view];
or
UIViewController* secondViewController = [[UIViewController alloc] initWithNibName:#"SecondViewControllerName" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:secondViewController animated:YES];
In second UIViewController xib file I have also one button which should take me back to first UIViewController. But I don't know how to navigate back to first UIViewController.
I tried:
[self.navigationController popViewControllerAnimated:YES];
for second way of navigating to second UIViewController, but I get unrecognized selector sent to instance error.
Many thanks in advance for any kind of help.

Entire project is made as Single View Application and targeted for iOS 5.1 in XCode 4.3. I have found sample project which does the same thing I am having trouble with. Here's URL for that project: http://www.devx.com/wireless/Article/42476/0/page/2
It is just written for earlier iOS version. Is anyone able to see what am I doing wrong, since I am really out of ideas?
PS: With this animations in code, or without - same problem occurs, so animations aren't problem, I've checked that.
[edit #2: Adding error info]
Here's error description. In main method on return line as listed below:
int main(int argc, char *argv[])
{
#autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
I get this error:
Thread 1: EXC_BAD_ACCESS (code=1, address=0xc00000008)
[edit #3: SOLUTION]
I would like to thank #btype for his solution below. I found out why code from edit #2 didn't work. Problem was doing this:
SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
INSIDE OF IBAction METHOD! Looks like ARC wiped my UIViewController as soon as end of scope was reached and that's why I was getting informations about sending messages to released instance. I made SecondViewController private field in my ViewController class and after that everything worked just fine.
If anyone thinks my explanation is wrong and knows what really bothered me, feel free to answer to this question and correct me.
Edit the code:
in AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
ViewController *viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
FirstViewController.m
- (IBAction)switchToSecondPage:(id)sender
{
[self.navigationController pushViewController:secondViewController animated:YES];
}
SeconViewController.m
- (IBAction)switchToFirstPage:(id)sender
{
[self.navigationController popToRootViewControllerAnimated:YES];
}
This should help.
My situation is very similar to this question . I have an app that is universal where iPhone is in portrait orientation and the iPad is in Landscape and I switch between all of my main screens using the appDelegate.window.rootViewController = newScreen; The iPhone app works perfectly. The iPad app will sometime throw the screen up in portrait orientation instead of landscape. Here is some sample transition code:
AppDelegate* appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
ViewController* v = nil;
if (IS_IPAD()) {
v = [[ViewController alloc] initWithNibName:#"ViewController-iPad" bundle:nil];
}else{
v = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
}
[appDelegate.window setRootViewController:(UIViewController*)v];
I also tried this from this other question :
AppDelegate* appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
ViewController* v = nil;
if (IS_IPAD()) {
v = [[ViewController alloc] initWithNibName:#"ViewController-iPad" bundle:nil];
}else{
v = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
}
[UIView
transitionWithView:appDelegate.window
duration:0.5
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^(void) {
BOOL oldState = [UIView areAnimationsEnabled];
[UIView setAnimationsEnabled:NO];
[appDelegate.window setRootViewController:(UIViewController*)v];
[UIView setAnimationsEnabled:oldState];
}
completion:nil];
But nothing has fixed it.
Also tried using [appDelegate.window makeKeyAndVisable] and [appDelegate.window makeKeyWindow] in the hopes that this would "shock" it into doing the correct orientation.
I've got it!
Here's what my transition block looks like. The key thing I did was copy the transform (the thing that does the actual rotation) from the CALayer. Note that you'll have to include the Quartz framework and #import <QuartzCore/QuartzCore.h> at the top of your file.
[UIView transitionWithView:self.window
duration:0.5
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^{
BOOL oldState = [UIView areAnimationsEnabled];
[UIView setAnimationsEnabled:NO];
target.view.layer.transform = window.rootViewController.view.layer.transform;
window.rootViewController = target;
[UIView setAnimationsEnabled:oldState];
} completion:nil];
