I have a problem regarding to MPMoviePlayer. I am using [self presentModalViewController:moviePlayer animated:YES]; to display player. When I click on Done button
(void) moviePlayBackDidFinish:(NSNotification*)notification
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
// Remove observer
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
//[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:1] animated:YES];
[self dismissModalViewControllerAnimated:YES];
//[self.view removeFromSuperview];
}
method calls. When it navigates to previous view, previous view's x and y ordinates get disturbed and everything is changed, means, the view gets changed. Any suggestions ?
Try using the methods presentMoviePlayerViewControllerAnimated: and dismisMoviePlayerViewControllerAnimated: instead of using presentModalViewController:animated: / dismissModalViewControllerAnimated:
Solved the problem by removing [[UIApplication sharedApplication] setStatusBarHidden:YES]; code.

I'm trying to present another viewController from my "SkScene".
This is my main viewController(tuViewController)
Code:
-(void) openTweetSheet{
FacebookLikeViewDemoViewController *ctrl = [[FacebookLikeViewDemoViewController alloc] initWithNibName:#"FacebookLikeViewDemoViewController" bundle:nil];
[self presentViewController:ctrl animated:YES completion:nil];
}
This is my "SkScene":
tuViewController *viewController = [[tuViewController alloc]init];
[viewController openTweetSheet];
And the viewController which i want to present is FacebookLikeViewDemoViewController and i need to have way back to "SkScene".
And i got sigabrt error, i tried few ways to present viewController but always with failure, one time i got swap to viewController but it was entirely black. I read a lot how to perform that, but i personally can't figure out. I appreciate your help.
I tried too with Notification Center.
Main viewController
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(goToGameOverViewController:)
name:#"GoToGameOverViewController"
object:nil];
-(void)goToGameOverViewController:(NSNotification *) notification {
FacebookLikeViewDemoViewController *helpVC = [[FacebookLikeViewDemoViewController alloc]initWithNibName:#"HelpViewController" bundle:nil];
UIViewController *rootVC = [UIApplication sharedApplication].keyWindow.rootViewController;
[rootVC presentViewController:helpVC animated:YES completion:nil];
}
SkScene
[[NSNotificationCenter defaultCenter]
postNotificationName:#"GoToGameOverViewController" object:self];
But i got the same error. I prefer to figure out why the way with notification won't work.
I assume by your question that you are looking to do some social media posting.
You can either pass a reference for your View Controller to your SKScene or you can use NSNotificationCenter instead. I prefer to use the latter.
First make sure you have added the Social.framework to your project.
Import the social framework into your View Controller #import <Social/Social.h>
Then in your View Controller's viewDidLoad method add this code:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(createTweet:)
name:#"CreateTweet"
object:nil];
Next add this method to your View Controller:
-(void)createTweet:(NSNotification *)notification
{
NSDictionary *tweetData = [notification userInfo];
NSString *tweetText = (NSString *)[tweetData objectForKey:#"tweetText"];
NSLog(#"%#",tweetText);
// build your tweet, facebook, etc...
SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
At the appropriate location in your SKScene, (won game, lost game, etc...) add this code:
NSString *tweetText = #"I just beat the last level.";
NSDictionary *userInfo = [NSDictionary dictionaryWithObject:tweetText forKey:#"tweetText"];
[[NSNotificationCenter defaultCenter] postNotificationName:#"CreateTweet" object:self userInfo:userInfo];
The above code sends a NSNotification, with text, which your View Controller will pick up and execute the specified method (which is createTweet in the above example).
After a long period of trying and searching the Internet and StackOverflow I could not find the answer I need.
My Problem is a warning:
Warning: Attempt to present <PAPasscodeViewController: 0x81cc8a0> on <ServerViewController: 0x75864b0> whose view is not in the window hierarchy!
I am using a Custom Control called "PAPasscodeViewController", the thing itself is working but when I try to display the view on the ApplicationDidBecomeActive method it displays this warning in the Consoleoutput.
I am using this method to keep track of the Notification:
[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(wait)
name:UIApplicationDidBecomeActiveNotification object:nil];
my -(void)wait is containing this:
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIApplicationDidBecomeActiveNotification object:nil];
NSLog(#"waiting");
[self performSelector:#selector(enterPasscode) withObject:nil afterDelay:.3f];
The App is having a RootViewController and a GeneralViewController, if the User already downloaded a Config package the GeneralViewController gets pushed in after starting as a modalView like this (in the viewDidLoad):
GeneralView = [[GeneralViewController alloc] initWithNibName:#"GeneralViewController" bundle:[NSBundle mainBundle]];
GeneralView.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
[self presentViewController:GeneralView animated:YES completion:nil];
In the GeneralView the User has more Options to open new Views through Buttons and they get pushed in through IBActions like the GeneralViewController.
So the Problem is occuring when this happens:
I am starting the App, Config Package was already installed and the User wants to track his ServerData on "ServerViewController", so he touches the appropriate Button for this.
Then the View gets pushed in (its now RootViewController (managed by AppDelegate)-> GeneralViewController(pushed in)-> ServerViewController(pushed in)), everything works fine.
Now when the User goes back to his Homescreen I am closing the modal View "ServerViewController" as follows:
-(void)viewDidAppear:(BOOL)animated{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(close:)
name:UIApplicationDidEnterBackgroundNotification object:nil];}
-(IBAction)close:(id)sender{
[self dismissViewControllerAnimated:YES completion:nil];
}
so when the App enters Backgrounding the ServerViewController gets dismissed, after resuming the App the GeneralViewController is now the active View Controller, and in his -(void)viewDidAppear I am calling the -(void)wait from above, it calls this function:
- (void)enterPasscode{
PAPasscodeViewController *passcodeViewController = [[PAPasscodeViewController alloc] initForAction:PasscodeActionEnter];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
passcodeViewController.backgroundView = [[UITableView alloc] initWithFrame:[UIScreen mainScreen].bounds style:UITableViewStyleGrouped];
}
passcodeViewController.delegate = self;
passcodeViewController.passcode = [configArray objectAtIndex:3];
passcodeViewController.simple = YES;
[self presentViewController:passcodeViewController animated:YES completion:nil];
}
This is working fine but then I am getting the annoying warning from above (here again so you dont have to scroll up)
Warning: Attempt to present <PAPasscodeViewController: 0x75d1c10> on <ServerViewController: 0x818b390> whose view is not in the window hierarchy!
actually this is confusing because I think my GeneralViewController is now the Active ViewController again...
Maybe I am just blinded by the simplicity of this Problem... but maybe someone here can help me understand.
I did NOT find any solution in any other post here in StackOverflow or other sites concerning that exact problem!
You have to remove self as observer when your ServerViewController is not shown. Add the following code to ServerViewController:
- (void)viewDidDisappear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
I have this question asked few times and I have tried a few different methods but have not been successful.
The latest method I have tried is as followed :
I included the ViewController that I wanted to show. I then put this code in the didReceiveRemoteNotification method.
CarFinderViewController *pvc = [[CarFinderViewController alloc] init];
// [self.window.rootViewController presentViewController:pvc animated:YES completion:nil];
[(UINavigationController *)self.window.rootViewController pushViewController:pvc animated:NO];
This did not work. I think the problem I may be having is that my initial view is not a navigation controller like a lot of the examples show.
This is a picture of my story board> The VC that I want to send the user to is the car finder (bottom right)
Can someone explain to me what I might be doing wrong?
You could use basically postNotification when you receive the Remote Notification
for exmaple in your didReceiveRemoteNotification post notification like this
[[NSNotificationCenter defaultCenter] postNotificationName:#"pushNotification" object:nil userInfo:userInfo];
now in your FirstViewController's you can register the FirstViewController for this notification like this
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(pushNotificationReceived) name:#"pushNotification" object:nil];
and in your method
-(void)pushNotificationReceived{
CarFinderViewController *pvc = [[CarFinderViewController alloc] init];
[self presentViewController:pvc animated:YES completion:nil];
}
don't forget to remove the observer from notification in your dealloc method
-(void)dealloc {
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
I think the simplest solution would be to show the CarFinderViewController as a modal view instead of trying to push it to a navigation controller which may or may not be visible at the time.
Another important point to avoid further inconsistencies I'd recommend you instantiate your CarFinderViewController from the storyboard instead of directly through the class methods.
Something like:
UIViewController * vc = self.window.rootViewController;
// You need to set the identifier from the Interface
// Builder for the following line to work
CarFinderViewController *pvc = [vc.storyboard instantiateViewControllerWithIdentifier:#"CarFinderViewController"];
[vc presentViewController:pvc animated:YES completion:nil];
My app has to be work in Ios5 and later Versions. I am adding MPMoviePlayerViewController to mainWindow When clicking on a button.the Done button of moviePlayerController is not removing the moviePlayerController from window.
My code is
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"001 ATSW" ofType:#"m4v"]];
self.player = [[MPMoviePlayerViewController alloc]
initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[self.player.view setFrame:[UIScreen mainScreen].bounds];
[[[UIApplication sharedApplication] keyWindow] addSubview:self.player.view];
[[self.player moviePlayer] play];
}
-(void)videoPlayBackDidFinish:(NSNotification*)notification {
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[self.player.moviePlayer stop];
self.player = nil;
[self.player.view removeFromSuperview];
}
How to remove the moviePlayerController on clicking the Done Button.
Any help please.
As stated in the documentation:
To dismiss a modally presented movie player view controller, call the dismissMoviePlayerViewControllerAnimated method.
As with other preconfigured controllers by Apple (such as the mail compose controller or image picker controller), you are responsible to dismiss the controller.
What you'll probably need to do is to actually using the
presentMoviePlayerViewControllerAnimated:(MPMoviePlayerViewController *)playerVC
method to present the MPMoviewPlayerViewController, and not inserting the view directly. As MPMoviewPlayerViewController is trying to dismiss itself when pressing the done button. And from what I can see there's no good way to listen for that and do it like when the movie finishes.
It might depend on how your app is built, but with something like
[[[[UIApplication sharedApplication] keyWindow] rootViewController] presentMoviePlayerViewControllerAnimated:player];
You should be able to replace all of the code to insert a view maualy, and then just using
[[[[UIApplication sharedApplication] keyWindow] rootViewController] dismissMoviePlayerViewControllerAnimated];
I am opening video in UIWebView with following code.
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(#"Navigatin Type %d %#",navigationType, request);
if (navigationType == 0) {
self.navigationItem.leftBarButtonItem = backBarBtn;
[self showVideoInWebView:[request.URL absoluteString]];
return NO;
}
return YES;
}
-(void)showVideoInWebView:(NSString *)urlStr
{
[mainWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlStr]]];
}
but when my mainWebView opens in full screen it hides my status bar.
I don't want to hide status bar
then how can I show my status bar?
You Can set Notification For making Status bar Visible.
Set The Notification for FullScreen Entry And Exit Notification ,SO that you could SHow And Hide The Status bar As Needed.
// For FullSCreen Entry
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoFullScreen:) name:#"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
// For FullSCreen Exit
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(videoExitFullScreen:) name:#"UIMoviePlayerControllerDidExitFullscreenNotification" object:nil];
- (void)videoFullScreen:(id)sender
{
[[UIApplication sharedApplication] setStatusBarHidden:NO animated:NO];
}
- (void)videoExitFullScreen:(id)sender
{
//Here do WHat You want
}
I am Sure It'll be helpful to you.
that is the behaviour of the built-in movie player AFAIK you cant change it ... maybe with an alternative HTML5 control.
when your UIWebView begin Fullscreen at that time write this line..
just try with this line..
-(void)moviePlayerEvent:(NSNotification*)aNotification{
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];
NSLog(#"%i", [UIApplication sharedApplication].statusBarHidden);
}
Another Way:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(VideoFullScreenExit:) name:UIWindowDidBecomeHiddenNotification object:self.view.window];
- (void)VideoFullScreenExit:(id)sender {
[[UIApplication sharedApplication] setStatusBarHidden:NO];
}
