    <p>I’m making a video that shows overlays at certain intervals of a video. I’ve managed to get the video to play. Now my objective is to watch/observe the currentPlaybackTime value and pause the video when it hits 2 seconds. </p> <p>After some research found that currentPlaybackTime does not support KOV. So I need to implement <a href="https://stackoverflow.com/questions/5791273/how-to-add-a-kvo-to-mpmovieplayer-currentplaybacktime">this solution</a> but I have no idea where to put the code - I’m very new to Objective C. I keep trying to put it in the ViewController (My only view) but the way its written hints to it being placed somewhere else… </p> <p>Should I create a new controller for it? Or do I override methods from the MediaPlayer framework?</p> <p>Here's my code:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import &lt;MediaPlayer/MediaPlayer.h&gt; @interface ViewController : UIViewController @property (strong, nonatomic) MPMoviePlayerController *movieController; @property(nonatomic) NSTimeInterval currentPlaybackTime; @end #import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (void)viewDidAppear:(BOOL)animated { self.movieController = [[MPMoviePlayerController alloc] init]; NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"m4v"]; NSURL *movieURL = [NSURL fileURLWithPath:moviePath]; self.movieController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; [self.movieController.view setFrame:CGRectMake (0, 0, 480, 326)]; [self.view addSubview:self.movieController.view]; [self.movieController play]; [self.movieController currentPlaybackTime]; } @end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
