  1. PONSNotification observer in custom UITableViewCell?
    text
    copied!<p>I'm building an app with iPod-like controls (play, pause, etc). The app has tableView with track names in each cell. I have a <code>MainViewController</code> with a <code>UITableView</code> and a custom <code>UITableViewCell</code> class. The player controls exist in the <code>MainViewController</code>.</p> <p>I also have a play/pause button in each cell. I've successfully set up <code>NSNotifications</code> to post a notification when the play button is pressed in the cell, so the track info is sent to the observer and responder method in <code>MainViewController</code> and the player controls (driven by <code>MPMoviePlayerController</code>) is initiated.</p> <p>This works, but once the track is playing, I can't figure out how to make the play/pause button in the cell "mirror" the state of the play/pause button in my iPod controls. I don't think adding a <code>NSNotification observer</code> in every cell is the correct way of doing this. </p> <p>Additional info: The play/pause button image in the <code>MainViewController</code> player is determined by a method that fires every half second and checks the <code>playbackstate</code> of the <code>MPMoviePlayerController</code>. If playing, the player button set's the play image. If paused, it set's the pause image. I'm thinking the implementation to also set the tableCell play/pause button will go here. </p> <p><strong>Edit</strong> This method is called whenever the playback state changes (via NSNotification), within my UITableViewController. (<code>playButton</code> is the play/pause button in the player controls, not the play/pause in the table cell in which I'm trying to update according to playback state).</p> <pre><code>- (void) updateViewForPlayerState { // Change playButton image depending on playback state [playButton setImage:((moviePlayer.playbackState == MPMoviePlaybackStatePlaying) ? pauseBtnBG : playBtnBG) forState:UIControlStateNormal]; } </code></pre>
