My iPhone is a iOS4(3.1.3 update).
I tryid this code.
#import <UIKit/UIKit.h>
#interface testViewController : UIViewController {
}
#end
//-------------------------------------------------
#import <MediaPlayer/MediaPlayer.h>
#import "testViewController.h"
#implementation testViewController
- (void)viewDidLoad {
[super viewDidLoad];
NSBundle *Bundle = [NSBundle mainBundle];
NSString *moviePath = [Bundle pathForResource:#"test" ofType:#"MOV"];
NSURL *videoURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerViewController *theMovie = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];
[self presentMoviePlayerViewControllerAnimated:theMovie];
theMovie.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[theMovie.moviePlayer play];
}
- (void)dealloc {
[super dealloc];
}
#end
when I run the aplication the video didn't work just only plays sound.
What is wrong with this code?
Thanks.
just add below source to code:-
[themovie.view setFrame: self.view.bounds];
[self.view addSubview:themovie.view];
Then it will worked sure......

I was trying out a project I worked on during iOS6. Tried running the same on iOS8 and the video is playing. Is there anything else I need to do?
- (void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"Mcdonald" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[moviePlayerController.view setFrame:[UIScreen mainScreen].bounds];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playMovie:) name:MPMoviePlayerLoadStateDidChangeNotification object:moviePlayerController];
}
- (void)playMovie:(NSNotification *)notification {
MPMoviePlayerController *player = notification.object;
if (player.loadState & MPMovieLoadStatePlayable)
{
NSLog(#"Movie is Ready to Play");
[player play];
}
}
Thanks.
Finally. Adding it to the UIWindow solved the problem for me.
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:#"disc" ofType:#"mp4"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
theMoviPlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMoviPlayer.controlStyle = MPMovieControlStyleFullscreen;
theMoviPlayer.view.transform = CGAffineTransformConcat(theMoviPlayer.view.transform, CGAffineTransformMakeRotation(M_PI_2));
UIWindow *backgroundWindow = [[UIApplication sharedApplication] keyWindow];
[theMoviPlayer.view setFrame:backgroundWindow.frame];
[backgroundWindow addSubview:theMoviPlayer.view];
[theMoviPlayer play];
Init your MPMoviePlayerController in .h file like below :
#property(strong,nonatomic)MPMoviePlayerController *moviePlayerController;
After above changes it will work .
Sample Code:
#interface ViewController : UIViewController
#property(strong,nonatomic)MPMoviePlayerController *moviePlayerController;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"Mcdonald" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
_moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
_moviePlayerController.allowsAirPlay = NO;
_moviePlayerController.shouldAutoplay = YES;
[_moviePlayerController.view setFrame:[UIScreen mainScreen].bounds];
_moviePlayerController.controlStyle=MPMovieControlStyleEmbedded;
[self.view addSubview:_moviePlayerController.view];
_moviePlayerController.fullscreen = YES;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playMovie:) name:MPMoviePlayerLoadStateDidChangeNotification object:moviePlayerController];
}
- (void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
}
- (void)playMovie:(NSNotification *)notification {
MPMoviePlayerController *player = notification.object;
if (player.loadState & MPMovieLoadStatePlayable)
{
NSLog(#"Movie is Ready to Play");
[player play];
}
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
I am trying to play a 2 musics they should play after each other with loop option ,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSString * music = [[NSBundle mainBundle] pathForResource:#"music" ofType:#"wav"];
myMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:music] error:NULL];
myMusic.delegate = self;
[myMusic play];
}
and play second music :
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
NSString * music = [[NSBundle mainBundle] pathForResource:#"music2" ofType:#"wav"];
myMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:music] error:NULL];
myMusic.delegate = self;
[myMusic play];
NSLog(#"MUSIC FINISH");
}
now the problem is how can I play previous music ?
Try this
ViewController.h
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#interface ViewController : UIViewController<AVAudioPlayerDelegate>
{
AVAudioPlayer *player;
int nIndex;
NSArray *arrPlayList;
}
#end
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
arrPlayList =[[NSArray alloc]initWithObjects:#"music1.wav",#"music2.wav",#"music3.wav", nil];
nIndex =[arrPlayList count]-1;
[self playSound:nIndex];
}
-(void)playSound:(int )index
{
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *strFilePath = [path stringByAppendingPathComponent:[arrPlayList objectAtIndex:index]];
NSURL *filePath = [NSURL fileURLWithPath:strFilePath];
player= [[AVAudioPlayer alloc] initWithContentsOfURL:filePath error:nil];
player.delegate=self;
[player play];
}
#pragma mark - AVFoundation Delegate Methods
-(void)audioPlayerDidFinishPlaying: (AVAudioPlayer *)player successfully:(BOOL)flag
{
NSLog(#"MUSIC FINISH");
if (nIndex==0) {
return;
}
nIndex--;
[self playSound:nIndex];
}
-(void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
NSLog(#"Decode Error occurred");
}
I am using following code: mY Sound is placed in myapp/Shared Resources/background_music.aiff
#synthesize window = _window;
- (void)dealloc
{
[backgroundSound release];
[_window release];
[super dealloc];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
sleep(3);
//this variable can be named differently
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/background_music.aiff",[[NSBundle mainBundle] resourcePath]]];
NSError *error;
backgroundSound = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
backgroundSound.numberOfLoops = -1;
//>> this will allow the file to //play an infinite number of times */
return YES;
}
#interface AppDelegate : UIResponder <UIApplicationDelegate>{
AVAudioPlayer *backgroundSound;
}
#property (strong, nonatomic) UIWindow *window;
#end
There are no errors and there is no looping sound.Kindly tell me what is going on.
Best Regards
ok i added [background play]; and it has started working fine..... that wasn't mentioned in the tutorial which i was following..
player = [[MPMoviePlayerController alloc] initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeStreaming;
if(player.playbackState == MPMoviePlaybackStatePlaying)
[player stop];
[player play];
I'm having some kind of problems with one thing, i'm making an app and i have a webview that shows a pdf file, and i have a button if clicked will call an UIDocumentInteractionController (open the pdf in a new window).
I will leave screenshots to make it easier:
When i open the app:
http://imgur.com/dpIEd
After i open the UIDocumentInteractionController:
http://imgur.com/VYV2N
Here's the code too
.h file
#interface pdfView : UIViewController <UIDocumentInteractionControllerDelegate>
{
IBOutlet UIActivityIndicatorView *loading;
IBOutlet UIWebView *Wview;
UIDocumentInteractionController *controller;
}
#property (nonatomic, retain) IBOutlet UIActivityIndicatorView *loading;
#property (nonatomic, retain) IBOutlet UIWebView *Wview;
#property (nonatomic, retain) UIDocumentInteractionController *controller;
-(void)buttonPressed;
-(IBAction)open_in:(id)sender;
-(IBAction)back:(id)sender;
#end
.m file
#import "pdfView.h"
#implementation pdfView
#synthesize loading,Wview;
#synthesize controller;
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
- (void)viewDidLoad
{
[loading startAnimating];
[super viewDidLoad];
Wview.scalesPageToFit = TRUE;
Wview.multipleTouchEnabled = TRUE;
[Wview setOpaque:NO];
NSString *path = [[NSBundle mainBundle] pathForResource:#"guia_seguranca_2" ofType:#"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[Wview loadRequest:request];
[loading stopAnimating];
}
-(IBAction)open_in:(id)sender
{
NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:#"guia_seguranca_2" ofType:#"pdf"];
UIDocumentInteractionController* preview = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:fileToOpen]];
preview.delegate = self;
[preview presentPreviewAnimated:YES];
[preview retain];
}
-(IBAction)back:(id)sender
{
[self.view removeFromSuperview];
}
-(void)buttonPressed
{
//[self.view removeFromSuperview];
NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:#"guia_seguranca_2" ofType:#"pdf"];
UIDocumentInteractionController* preview = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:fileToOpen]];
preview.delegate = self;
[preview presentPreviewAnimated:YES];
[preview retain];
}
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
return self;
}
- (UIView *)documentInteractionControllerViewForPreview:(UIDocumentInteractionController *)controller
{
return self.view;
}
- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller
{
return self.view.frame;
}
- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)controller
{
[self.controller autorelease];
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc
{
[super dealloc];
[Wview release];
[loading release];
}
#end
Thanks in advance.....
I would suggest not useing the webview and using a pdf app (ibook, cloudreader) like this.
//name of pdf
NSString * pathString = #"userguide";
//get pdf path
NSString * filePath = [[NSBundle mainBundle] pathForResource:pathString ofType:#"pdf"];
NSURL *url = [NSURL fileURLWithPath:filePath];
self.docController = [UIDocumentInteractionController interactionControllerWithURL:url];
BOOL isValid = [self.docController presentOpenInMenuFromRect:self.handBookLaunch.frame inView:self.view animated:YES];
if (!isValid) {
NSString * messageString = [NSString stringWithFormat:#"No PDF reader was found on your device. Please download a PDF reader (eg. iBooks)."];
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"Error" message:messageString delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
Solved, added this code for layout verification:
-(void) viewWillAppear:(BOOL)animated
{
CGRect arect=[[UIScreen mainScreen]applicationFrame];
CGRect anotherrect=[[UIApplication sharedApplication]statusBarFrame];
if(self.view.center.y==arect.size.height/2)
self.view.center=CGPointMake(self.view.center.x, self.view.center.y+anotherrect.size.height); // fix silliness in IB that makes view start 20 pixels higher than it should on iPhone
}

Im doing an application that needs to play alot of short sounds (mp3-files). Im using AvAudioPlayer and the sounds are playing just fine, BUT the leaks are building up until my app crashes.
I have a seperate class for the player
AVSnd.h
#import <Foundation/Foundation.h>
#import <AVFoundation/AVFoundation.h>
#interface AVSoundPlayer : NSObject <AVAudioPlayerDelegate> {
AVAudioPlayer *msoundPlayer;
}
#property (nonatomic, retain) AVAudioPlayer *msoundPlayer;
-(id)initWithMp3File: (NSString *)inString;
-(void) playNum:(int)num;
#end
AVSND.m
#implementation AVSoundPlayer
#synthesize msoundPlayer;
-(id)initWithMp3File: (NSString *)fileName{
if (self = [super init]){
NSBundle *mainBundle = [NSBundle mainBundle];
NSError *error;
NSURL *sURL = [NSURL fileURLWithPath:[mainBundle
pathForResource:fileName ofType:#"mp3"]];
self.msoundPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:sURL error:&error];
if (!self.msoundPlayer) {
NSLog(#"Sound player problem: %#", [error localizedDescription]);
}
}
return self;
}
-(void) playNum:(int)num{
self.msoundPlayer.numberOfLoops = num;
[self.msoundPlayer prepareToPlay];
AVAudioPlayer *tmpPlayer = self.msoundPlayer;
[tmpPlayer play];
}
- (void)dealloc {
[self.msoundPlayer release];
[super dealloc];
}
#end
Then I make an instance of this object in the views i want sound.
in .h files I add following lines:
#class AVSnd;
AVSnd *mPlayer;
#property (nonatomic, retain) AVSnd *mPlayer;
and in .m files i use:
#synthezise mPlayer;
[self.mPlayer initWithMp3File:#"soundFileName"];
[self.mPlayer playNum:1];
[self.mPlayer release];
But why do I get memory-leaks every time i play a sound? Should i implement the player in another way?
Thank you so much for any help!
I had the same problem and solved it with autorelease:
self.audioPlayer = [[[AVAudioPlayer alloc]
initWithContentsOfURL:url error:&error] autorelease];
self.msoundPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:sURL error:&error];
Here you are retaining the object twice, in self. (because of the property), and when alloc. It could be the reason.
