Customizing Video Controllers in iOS Apps

In this article, we’ll explore how to create a video controller similar to VEVO’s in an iOS app. We’ll dive into the world of MPMoviePlayerController and discuss customizing its view, adding progress bars, and more.

Understanding MPMoviePlayerController

MPMoviePlayerController is a built-in class in Apple’s iOS SDK that allows you to play movies and other video content in your app. It provides a convenient way to display video playback controls, such as play, pause, and seek bars.

Creating an MPMoviePlayerController Instance

To create an instance of MPMoviePlayerController, you’ll need to provide it with a URL pointing to the video file you want to play:

{< highlight objective-c >}
- (void)viewDidLoad {
    // ...
    NSURL *videoURL = [NSURL URLWithString:@"https://example.com/video.mp4"];
    self.player = [[MPMoviePlayerControllerViewController alloc] initWithContentURL:videoURL];
    self.player.view.frame = self.view.bounds;
    [self addChildViewController:self.player];
    [self.view addSubview:self.player.view];
}
{< /highlight >}

In this example, we’re creating a MPMoviePlayerController instance and passing it a URL pointing to our video file. We’re also setting the frame of its view to match our app’s main view.

Customizing the MPMoviePlayerController View

One of the most powerful features of MPMoviePlayerController is its ability to customize its view. You can add subviews to its view property, such as custom buttons or other UI elements:

{< highlight objective-c >}
- (void)viewDidLoad {
    // ...
    self.player.view.backgroundColor = [UIColor blackColor];
    
    UIButton *playButton = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 50, 30)];
    playButton.backgroundColor = [UIColor redColor];
    playButton.setTitle(@"Play", forState:UIControlStateNormal);
    [self.player.view addSubview:playButton];
}
{< /highlight >}

In this example, we’re setting the background color of the MPMoviePlayerController view and adding a custom button on top of it.

Adding Progress Bars

To add progress bars to your video controller, you can use the view property of MPMoviePlayerController. Here’s an example:

{< highlight objective-c >}
- (void)viewDidLoad {
    // ...
    self.player.view.backgroundColor = [UIColor blackColor];
    
    UILabel *progressLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 50, 200, 20)];
    progressLabel.backgroundColor = [UIColor grayColor];
    progressLabel.text = @"0.00%";
    [self.player.view addSubview:progressLabel];
}
{< /highlight >}

In this example, we’re creating a label and adding it to the MPMoviePlayerController view.

Handling Video Playback Events

To respond to video playback events, such as when the player starts or stops playing, you’ll need to implement the delegate methods of MPMoviePlayerController. Here’s an example:

{< highlight objective-c >}
- (void)playerStateChanged:(MPMoviePlayerController *)player state:(int)state {
    switch (state) {
        case MPMoviePlayerStatePlaying:
            NSLog(@"Video is playing");
            break;
        case MPMoviePlayerState Paused:
            NSLog(@"Video is paused");
            break;
        default:
            NSLog(@"Unknown player state");
            break;
    }
}
{< /highlight >}

In this example, we’re implementing the playerStateChanged method and logging a message when the video starts or stops playing.

Customizing Other Video Controllers

While MPMoviePlayerController is a great starting point for creating video controllers, there are other options available. Here are a few examples:

AVPlayer

AVPlayer is another powerful class in Apple’s iOS SDK that allows you to play movies and other video content. It provides many more features than MPMoviePlayerController, including support for multiple video tracks and chapters.

To create an instance of AVPlayer, you’ll need to provide it with a URL pointing to the video file you want to play:

{< highlight objective-c >}
- (void)viewDidLoad {
    // ...
    NSURL *videoURL = [NSURL URLWithString:@"https://example.com/video.mp4"];
    self.player = [[AVPlayer alloc] initWithURL:videoURL];
    AVPlayerItem *item = [AVPlayerItem playerItemWithURL:videoURL];
    self.player.addItem:item;
}
{< /highlight >}

In this example, we’re creating an instance of AVPlayer and passing it a URL pointing to our video file. We’re also creating an AVPlayerItem instance and adding it to the AVPlayer.

AVAudioPlayer

AVAudioPlayer is another class in Apple’s iOS SDK that allows you to play audio files. It provides many more features than MPMusicPlayerController, including support for multiple audio tracks and chapters.

To create an instance of AVAudioPlayer, you’ll need to provide it with a URL pointing to the audio file you want to play:

{< highlight objective-c >}
- (void)viewDidLoad {
    // ...
    NSURL *audioURL = [NSURL URLWithString:@"https://example.com/audio.mp3"];
    self.player = [[AVAudioPlayer alloc] initWithURL:audioURL];
}
{< /highlight >}

In this example, we’re creating an instance of AVAudioPlayer and passing it a URL pointing to our audio file.

Conclusion

Creating a video controller similar to VEVO’s in an iOS app requires some knowledge of Apple’s iOS SDK and its various classes. In this article, we’ve explored how to create an instance of MPMoviePlayerController, customize its view, add progress bars, and handle video playback events. We’ve also discussed other options available for creating video controllers, including AVPlayer and AVAudioPlayer.

By following the examples and code snippets provided in this article, you should be able to create a video controller that rivals VEVO’s in terms of functionality and user experience.
