    <p>1) <code>AVPlayer</code> will buffer the video in several cases, none cleary documented. I'd say you can expect buffering when you init the video, and when you replace the current item. You can observe <code>currentItem.loadedTimeRanges</code> to know what's going on. That property will tell you which video time ranges has been loaded.</p> <p>Also, there is a few other <code>currentItem</code> properties that may help you: <code>playbackLikelyToKeepUp</code>, <code>playbackBufferFull</code> and <code>playbackBufferEmpty</code>.</p> <p>Achieving a perfect gapless playback is not easy.</p> <pre><code>/* player is an instance of AVPlayer */ [player addObserver:self forKeyPath:@"currentItem.loadedTimeRanges" options:NSKeyValueObservingOptionNew context:kTimeRangesKVO]; </code></pre> <p>In <code>observeValueForKeyPath:ofObject:change:context:</code>:</p> <pre><code>if (kTimeRangesKVO == context) { NSArray *timeRanges = (NSArray *)[change objectForKey:NSKeyValueChangeNewKey]; if (timeRanges &amp;&amp; [timeRanges count]) { CMTimeRange timerange = [[timeRanges objectAtIndex:0] CMTimeRangeValue]; NSLog(@" . . . %.5f -&gt; %.5f", CMTimeGetSeconds(timerange.start), CMTimeGetSeconds(CMTimeAdd(timerange.start, timerange.duration))); } } </code></pre> <p>2) Just keep an eye on <code>player.rate</code>.</p> <pre><code>[player addObserver:self forKeyPath:@"rate" options:NSKeyValueObservingOptionNew context:kRateDidChangeKVO]; </code></pre> <p>Then in your <code>observeValueForKeyPath:ofObject:change:context:</code>:</p> <pre><code> if (kRateDidChangeKVO == context) { NSLog(@"Player playback rate changed: %.5f", player.rate); if (player.rate == 0.0) { NSLog(@" . . . PAUSED (or just started)"); } } </code></pre> <p>3) You can <a href="https://stackoverflow.com/search?q=movie%20images%20avfoundation%20answers:1%20isquestion:1&amp;submit=search">build a movie of a given length using a still image</a> but it's easier to use a regular <code>UIImageView</code> on top of the player. Hide/show it when needed. </p> <p><strong>Sample project</strong>: feel free to play with <a href="https://github.com/djromero/AVFoundationQuestions/tree/10648963" rel="nofollow noreferrer">the code I wrote to support my answer</a>.</p>

    2. COAFAIK there is no public api to work with AVPlayer buffer. If you want to keep buffering beyond the pause point you can fake the pause: keep playing w/out volume and with the view hidden, then use seekToTime to resume playback.

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.
