How to play video in iphone using programming?

Play video in iPhone using programming is very simple. Many framworks are available for playing video in iphone . I am giving simple class file playvideo with your xib file. Regarding this project complete source code is also given below.

playvideo.h

#import <UIKit/UIKit.h>
#import <MobileCoreServices/UTCoreTypes.h>
#import <MediaPlayer/MediaPlayer.h>
@interface PlayVideo : UIViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate>
//Button Backend Function
- (IBAction)PlayVideo:(id)sender;
//For Opening UIImagePickerController
- (BOOL) startMediaBrowserFromViewController: (UIViewController*) controller
                               usingDelegate: (id <UIImagePickerControllerDelegate,
                                               UINavigationControllerDelegate>) delegate;
@end

playvideo.m

#import "PlayVideo.h"
@implementation PlayVideo

        // Custom initialization
    }
    return self;
}
- (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.
}
#pragma mark - View lifecycle
- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
