I have spent whole day today to get MPMoviePlayerViewController working on iOS5 but somehow not able to get it working no matter what I do! Following code works absolutely fine on any iOS other than iOS 5.0. Couldn't get much help related to this topic. Could anyone know what has been changed in iOs 5.0 that made following simple code burst! I noticed that on iOS 5.0, it goes in infinite loop of checking loadstate to MPMovieLoadStateUnknown! It never becomes Playable!
#import "MyMoviePlayer.h"
#implementation MyMoviePlayer
#synthesize moviePlayerViewController;
- (void) checkAndPlay:(UIViewController *)view {
if ([[moviePlayerViewController moviePlayer] loadState] == MPMovieLoadStateUnknown) {
NSLog(#"Rechecking");
[NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:#selector(checkAndPlay:) userInfo:nil repeats:NO];
} else {
[moviePlayerViewController setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[view presentModalViewController:moviePlayerViewController animated:YES];
}
}
- (void)play:(NSURL*)movieURL andWithView:(UIViewController *)view {
moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[self checkAndPlay:view];
}

I'm having a very strange problem. I want a video to appear in landscape mode, but I can't seem to make it work. Even if I can't make it always show Landscape, at least I want it to show ok, and I can't make that either!! Here is my code:
#import "SplashViewController.h"
#import "MainViewController.h"
#import "MediaPlayer/MediaPlayer.h"
#interface SplashViewController ()
#property (nonatomic, retain) NSTimer *timer;
#end
#implementation SplashViewController
#synthesize timer = _timer;
-(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)toInterfaceOrientation
{
return YES;
}
- (id)init
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self = [self initWithNibName:#"SplashViewController_iPhone" bundle:nil];
} else {
self = [self initWithNibName:#"SplashViewController_iPad" bundle:nil];
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self.navigationController setNavigationBarHidden:YES];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewWillAppear:animated];
NSString *url = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"intro.mp4"];
playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:[playerViewController moviePlayer]];
[playerViewController shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
[self.view addSubview:playerViewController.view];
//play movie
MPMoviePlayerController *player = [playerViewController moviePlayer];
player.scalingMode = MPMovieScalingModeAspectFill;
[player play];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player stop];
[player.view removeFromSuperview];
[self loadMainView];
}
- (void)loadMainView
{
MainViewController *mainVC = [[MainViewController alloc] init];
[self.navigationController pushViewController:mainVC animated:YES];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
#end
And here comes the weirdness...
If I start the app with my iPad physically in Landscape Mode, the video shows like this (please not that the bar at the top is shorter than the widht! :O)
If I then rotate the iPad to Portrait, it looks like this:
But then, if I start the app with my iPad physically in Portrait Mode, the video shows like this:
And if I then rotate the iPad to Landscape, it looks like this:
Which is GREAT! This final image is what I would like the video to always look like.
Any ideas what I might be doing wrong???
Thanks!
EDIT 1
Ok, with #Tark answer I was able to fix the player display issue. Now it's showing fine no matter how I start the app. Thanks for that!! What is missing now is the always landscape mode.
I tried with the following methods:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (interfaceOrientation==UIInterfaceOrientationLandscapeRight)
return YES;
return NO;
}
I also tried inserting the row
Initial interface orientation = Landscape (right home button)
In the Info.plist
What I'm getting is that if I start the app in Landscape mode, if I rotate the iPad to Portrait, it stays in Landscape. GREAT!
But if I start the app in Portrait mode, the video shows in Portrait mode. Once I rotate it to Landscape, I can't rotate it back to Portrait, which is good, but I don't want it to start in Portrait!
EDIT 2
Ok, now this is even more weird. If I try it on an iPhone, it works great. No matter if I start the app in Landscape or Portrait, the video is shown always in Landscape.
But if I try it on an iPad, the problem in EDIT 1 arises... :S
Any ideas?
Thanks!
Have you tried setting the frame of the MPMoviePlayerViewControllers view when you add it as a subview?
...
playerViewController.view.frame = self.view.bounds;
[self.view addSubview:playerViewController.view];
...
To make the app only run in landscape mode, you should make sure that you have only selected the orientations you want in the app plist. In Xcode 4 there is a handy Supported Interface Orientations section in the target settings, make sure you only select landscape here. If you still have the issue, you have to make sure that you are disabling autorotation on all visible controllers in the view stack.
shouldAutorotateToInterfaceOrientation is deprecated as of iOS 6, Have you tried using supportedInterfaceOrientations?
If you are trying to support iOS 5 & 6 then I believe you need to use both:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
I haven't tested this so take it for what it's worth.
I have NSTimer in ViewController Class.. And all the methods for NStimer are in that class.. My NSTimer is working properly for play and pause... When i press home button on iPhone also the timer is working properly(it starts running from the time where the application enters into background when the application enters into foreground)... In my application i am rising an alert quickly when my application enters into foreground(UIAlertview in application didEnterForeGround). Here my NSTimer is running when the alert is on the screen(didn't give response to alert).. I want stop the NSTimer Upto the User responding to my alert... After that I want to start the NSTimer... How Can i do that...? Please help me... Thanks in Advance... I want call the NSTimer methods from Appdelegate.m file... Iam calling these methods properly... And the methods in ViewController are called.. But the action is Not Performing... For the Same method when call from viewController class it is working...
enter code here
ViewController.h
+(ExamViewController *)evcInstance;
ViewController.m
ExamViewController *evc = nil;
#implementation ExamViewController
+(ExamViewController *)evcInstance
{
if(!evc)
{
evc = [[ExamViewController alloc] init];
}
return evc;
}
- (void)onStartPressed
{
stopwatchtimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:#selector(updateTimer:) userInfo:nil repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:stopwatchtimer forMode:NSRunLoopCommonModes];
resume.hidden = YES;
resume.enabled=NO;
pause.hidden = NO;
pause.enabled=YES;
}
- (void)onStopPressed
{
[stopwatchtimer invalidate];
stopwatchtimer = nil;
pause.hidden = YES;
pause.enabled=NO;
resume.hidden = NO;
resume.enabled=YES;
}
Appdelegate.m
- (void)applicationWillEnterForeground:(UIApplication *)application
{
[[ExamViewController evcInstance] onStopPressed];
NSLog(#"applicationWillEnterForeground");
if(viewCalled ==YES)
{
UIAlertView *alertview=[[UIAlertView alloc]initWithTitle:#"" message:#"DO! You Want To continue" delegate:self cancelButtonTitle:#"YES" otherButtonTitles:#"NO", nil];
[alertview show];
[alertview release];
}
/*
Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
*/
}
a few things:
1) It looks like an incomplete singleton design. If you really want a singleton, refer to a post like this one.
2) No need to add stopwatchtimer to the current run loop. The scheduledTimerWithTimeInterval method schedules it for you.
3) I don't see where you declare stopwatch timer, but be sure to declare it as a retained property (or strong in ARC).
4) To stop the timer, just call [stopwatchtimer invalidate]; To restart it, re-instantiate and overwrite the old one using the same scheduledTimerWithTimeInterval class method that you called originally.
5) To do anything when an alert view completes, implement the delegate method:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
So you can invalidate the timer before presenting the alert, then rebuild it when you get notified the alert is finished.
Im having a strange problem that only occurs on the iPad version of my game. When I bring up the GameCenter leaderboard, it appears like normal. No issues there. But when you tap the close button the leader board disappears and the cocos2d scene goes black. No errors, nothing. Nothing I do can bring the screen back. Ive tried resuming the director and even tried some solutions on a similar thread.
Here is my code in the cocos2d scene. GCController is just a subclass of the RootViewController, nothing special:
tempVC = [[GCController alloc] init];
GKLeaderboardViewController *leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];
if (leaderboardController != nil)
{
leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
leaderboardController.category = [NSString stringWithFormat:#"%#%#", [self cleanString:selectedSong], #"TotalHD"];
leaderboardController.leaderboardDelegate = self;
[[[CCDirector sharedDirector] openGLView] addSubview:tempVC.view];
[tempVC presentModalViewController:leaderboardController animated:YES];
}
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
[tempVC dismissModalViewControllerAnimated:YES];
[tempVC.view.superview removeFromSuperview];
[tempVC release];
}
Anyone have any ideas? If I can provide any more information let me know. Thanks.
You are not providing enough code. I see no fault in the code you are showing at the moment. Your most likely cause of a black screen (depending on how you do things) is that timers have been interrupted and you may need to reset them with
- (void) onEnter;
or
- (void) onEnterTransitionDidFinish;
If that isn't it then post more code and I will check back. We need to see when the view is presented and what it should return to.
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
[tempVC dismissModalViewControllerAnimated:YES];
**[tempVC.view removeFromSuperview];**
}
I'm looking to stop an audio file from playing when the view is changed.
I'm using a tabController and I would like the audio that's playing to stop when the user moves to a different view. I'm not sure where and how I would do this. in the viewDidUnload perhaps?
here's the method I'm using to play the audio file:
-(void)startPlaying {
[NSTimer scheduledTimerWithTimeInterval:15 target:self selector:#selector(startPlaying) userInfo:nil repeats:NO];
NSString *audioSoundPath = [[ NSBundle mainBundle] pathForResource:#"audio_file" ofType:#"caf"];
CFURLRef audioURL = (CFURLRef) [NSURL fileURLWithPath:audioSoundPath];
AudioServicesCreateSystemSoundID(audioURL, &audioID);
AudioServicesPlaySystemSound(audioID);
}
thanks for any help
Something like this in your view controller (untested):
- (void)viewDidLoad
{
[super viewDidLoad];
// Load sample
NSString *audioSoundPath = [[NSBundle mainBundle] pathForResource:#"audio_file"
ofType:#"caf"];
CFURLRef audioURL = (CFURLRef)[NSURL fileURLWithPath:audioSoundPath];
AudioServicesCreateSystemSoundID(audioURL, &audioID)
}
- (void)viewDidUnload
{
// Dispose sample when view is unloaded
AudioServicesDisposeSystemSoundID(audioID);
[super viewDidUnload];
}
// Lets play when view is visible (could also be changed to viewWillAppear:)
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self startPlaying];
}
// Stop audio when view is gone (could also be changed to viewDidDisappear:)
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
if([self.audioTimer isValid]) {
[self.audioTimer invalidate];
}
self.timer = nil;
}
// Start playing sound and reschedule in 15 seconds.
-(void)startPlaying
{
self.audioTimer = [NSTimer scheduledTimerWithTimeInterval:15 target:self
selector:#selector(startPlaying)
userInfo:nil
repeats:NO];
AudioServicesPlaySystemSound(audioID);
}
Missing:
Error checking
Property or ivar for audioTimer.
Could also keep the same timer, with repeats YES.
Freeing resources in dealloc.
Testing
I have created a voice recording app. It works fine on an iPhone 3G but crashes on an original 2G iPhone.
The crash occurs in the following methods:
-(void)RecordbtnPressed:(UIButton *)sender {
[Record removeFromSuperview];
stop.alpha=1;
T=[NSTimer scheduledTimerWithTimeInterval:1 target:self :#selector(startTimer) userInfo:nil repeats:YES];
persistance_Obj->recordClicked=TRUE;
[AudioViewController_Obj startRecording];
}
-(void)StopbtnPressed:(UIButton *)sender {
printf("\n stop pressed");
persistance_Obj->recordClicked=FALSE;
[T invalidate];
T=nil;
[AudioViewController_Obj stopRecording];
MainMenu * obj_RV=[[MainMenu alloc] init];
[self.navigationController pushViewController:obj_RV animated:YES];
[obj_RV release];
}
The crash occurs right when I click the stop button, calling the second method. What could be the cause of this crash?
Ok, just get clear? The iPhone 1G you are talking about is actually the first released one and the iPhone 2G you are talking about is actually the iPhone 3G?
Maybe you could show us some code on where the app crashes?
