MediaPlayer Framework

In this post we will have a look at the MediaPlayer framework but before beginning I would like you to have a look at the AVFoundatioin framework post which will explain you how to add a framework into your current project, read that post first if you are a beginner else continue reading.

Design Phase: In this post we will try to run a video on the button touch and that video will be displayed in the iphone simulator, here's a look at the final output

Step 1: Open Xcode create a window based application project add a UIViewController subclass file and name it Myview, now you must be having two files into your class folder that’s Myview.h and Myview.m so now its time to add a video into the project

Refer AVFoundation post for this as well

Step 2: Now once you have added the MediaPlayer framework and a video file into your project its time to code now, declare an object of UIButton in the .h file of Myview also declare a function called PlayMovie which will play the movie for you. here's how the code looks

@interface Myview : UIViewController {

UIButton *btn;

}

-(void) PlayMovie;

@end

Step 3: Select the .m file of Myview and allocate memory for the UIButton object into the init method,

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {

    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {

        // Custom initialization

//setting the button type

btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

//setting the button frame

[btn setFrame: CGRectMake(105, 99, 72, 37)];

//setting the title for the button

[btn setTitle:@"Play" forState:UIControlStateNormal];

//adding function to the button

[btn addTarget:self action:@selector(PlayMovie) forControlEvents:UIControlEventTouchUpInside];

    }

    return self;

}

now its time to give body to the PlayMovie function here’s the code for that

-(void) PlayMovie

{

//specifying the location of the video file

NSURL *movieurl = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"TAJ" ofType:@"mp4"]];

//creating the object of MPMoviePlayerController and suppling the URL of the file to the object of the movie player controller

MPMoviePlayerController *movieplayerController = [[MPMoviePlayerController alloc]initWithContentURL:movieurl];

//play the movie

[movieplayerController play];

}

Code Explanation: In the above code we have created the object of the MediaPlayerController and this class has a init method which takes a parameter of NSURL so in the NSURL object called movieurl I have supplied the location of the video file which is present into the bundle (groups & files) with the help of NSBundle class.

Step 4: Go to the loadView method present into the .m file of the Myview and add the Button view to the current view 

- (void)loadView {

[super loadView];

[self.view addSubview:btn];

}

after that go to the AppDelegate.m file of your project and add the current view to your iPhone window

#import "VideProjectAppDelegate.h"

#import "Myview.h"

@implementation VideProjectAppDelegate

@synthesize window;

- (void)applicationDidFinishLaunching:(UIApplication *)application {    

    // Override point for customization after application launch

Myview * obj = [[Myview alloc]init];

[window addSubview:obj.view];

        [window makeKeyAndVisible];

}

Step 5: Press Build and Go and get the following output
