    <p>If avPlayerLayer is the only class interacting with the avPlayer, you don't need to maintain a reference to it with a property in the class you're using to present it (unless this class uses it outside the code you've shared). In fact, this is probably why it isn't working the way you expect.</p> <p>The reason the clip continues to play (I think) is because the player isn't being deallocated. You create it, own it with the <em>strong</em> property in your class, than it's owned again by the AVPlayerLayer class you hand it to. So when the AVPlayerLayer is deallocated, the AVPlayer looses one owner. But it still has an owner (your class), so it isn't deallocated, and it keeps playing. The solution here is to get rid of your owning property altogether for *avPlayer. You don't need it. Create the AVPlayer and pass it to AVPlayerLayer. That should be all that's needed.</p> <p>Something else you could do which might fix the behavior but not the problem, call:</p> <pre><code>[avPlayer pause] </code></pre> <p>In your AVPlayerLayer's dealloc method.</p> <p>Re: Strong vs. Weak references: A strong reference implies ownership. As ARC is managing memory, it'll be doing all the [object retain]ing and [object release]ing that you previously would have done in code OR that you would have done with properties, ie:</p> <pre><code>@property (retain) NSObject *iAmRetainedWhenProperyIsAssigned; </code></pre> <p>So <em>now</em> with ARC, we simple users don't use words like retain or release in code or when defining properties. But we still design software. ARC is smart, but not smart enough to infer the architectural implications of relationships that we're defining. It still needs to be told that a class "owns" a reference to the object that the property refers to. Which reduces us, in the most basic terms:</p> <p>(strong) means to ARC what (retain) meant to properties pre-ARC (owned/retained)</p> <p>(weak) means to ARC what (assign) meant to properites pre-ARC (not owned/not retained)</p>

    1. COThanks for the suggestions. I'll try some of this out tomorrow and see what I come up with. I originally had the AVPlayer as just an iVar, but when I started having problems with it I switched it. Also there is no stop property on the AVPLayer class. That is only available on the AVAudioPlayer class from what I've read in the docs. In any case thanks again for taking the time to write up such a detailed post.

    2. COEdited [avPlayer stop] to [avPlayer pause]. I mistakenly thought that AVPLayerLayer was your own subclass, I didn't realize it was a CALayer subclass.

    3. COFrom what I understand releasing and deallocating is all managed by ARC and you're not even allowed to call those functions. Is that wrong?

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.
