Introduction
This blog entry adds methods to the UIViewController class for presenting and dismissing a movie player using a specific set of animations. The transitions used by these methods are the same ones used by the YouTube and iPod applications to display video content.
Steps :-
1. Add "MediaPlayer.framework " as existing framework
2. Make another viewController class, suppose we name it "MoviePlayerViewController"
3. In "MoviePlayerViewController.h", add the below code,
#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
@interface MoviePlayerViewController : UIViewController
{ MPMoviePlayerController *mp;
NSURL *movieURL;
}
- (id)initWithPath:(NSString *)moviePath;
- (void)readyPlayer;
- (void) changeTheViewToPortrait:(BOOL)portrait andDuration:(NSTimeInterval)duration;
@end
4. In "MoviePlayerViewController.m", add the below code,
#import "MoviePlayerViewController.h"
#pragma mark -
#pragma mark Compiler Directives & Static Variables
@implementation MoviePlayerViewController
-(void)viewWillDisappear:(BOOL) animated
{ if(mp) {[mp stop];
}
}
- (id)initWithPath:(NSString *)moviePath
{ mp.controlStyle = MPMovieControlStyleNone;
// Initialize and create movie URL
if (self = [super init])
{movieURL = [NSURL fileURLWithPath:moviePath];
[movieURL retain];
}
return self;
}
- (void) moviePlayerLoadStateChanged:(NSNotification*)notification
{ [mp setControlStyle:MPMovieControlStyleFullscreen];
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
NSString *deviceModel = [NSString stringWithFormat: @"Device Type: %@\n", [[UIDevice currentDevice] model]];
NSRange range = [deviceModel rangeOfString:@"iPad"];
if(range.location != NSNotFound){if ([mp loadState] != MPMovieLoadStateUnknown)
{[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
//view bounds are defined as par iPad screen, so adjust accordingly
[[self view] setBounds:CGRectMake(0, 0, 1024, 748)];
UIInterfaceOrientation interfaceOrientation = [self interfaceOrientation];
if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft ){[[mp view] setFrame:CGRectMake(0, 0, 1024, 748)];
}
else if(interfaceOrientation == UIInterfaceOrientationLandscapeRight ){[[mp view] setFrame:CGRectMake(0, 0, 1024, 748)];
}
[[self view] addSubview:[mp view]];
[mp play];
}
}
else
{ if ([mp loadState] != MPMovieLoadStateUnknown)
{[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
UIInterfaceOrientation interfaceOrientation = [self interfaceOrientation];
if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight){[[UIApplication sharedApplication] setStatusBarOrientation:interfaceOrientation animated:NO];
}
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
[[self view] setBounds:CGRectMake(0, 0, 1024, 768)];
[[self view] setCenter:CGPointMake(160, 240)];
[[mp view] setFrame:CGRectMake(0, 0, 1024, 748)];
[[self view] setTransform:CGAffineTransformMakeRotation(M_PI / 2)];
[[self view] addSubview:[mp view]];
[mp play];
}
}
#endif

5. Now wherever , you want to play the movie file, add the below code,
NSString *movieFile=[[NSBundle mainBundle] pathForResource:@"test" ofType:@"mp4"];
// Create custom movie player
moviePlayer = [[[MoviePlayerViewController alloc] initWithPath:movieFile] autorelease];
[self presentModalViewController:moviePlayer animated:NO];
[moviePlayer readyPlayer]; In this class, import "MoviePlayerViewController.h" & "moviePlayer" is a global object of MoviePlayerViewController
