    <p>I have 2 buttons in my UIView underneath a video,a play and a stop button.When Play button is clicked,it turns out to pause button and vice-versa.Here is the implementation code:</p> <pre><code>-(UIView *)subViewControlsView{ UIView *subViewWithControls = [[[UIView alloc]init]autorelease]; subViewWithControls = [[UIView alloc]initWithFrame:CGRectMake((self.view.frame.size.width - xPoint_Pad) - 147, 630, 147, 44)]; [subViewWithControls setBackgroundColor:[UIColor clearColor]]; playButton = [UIButton buttonWithType:UIButtonTypeCustom]; [playButton setFrame:CGRectMake(0, 0, 44, 44)]; [playButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal]; [playButton setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateSelected]; [playButton addTarget:self action:@selector(play:) forControlEvents:UIControlEventTouchUpInside]; [subViewWithControls addSubview:playButton]; stopButton = [UIButton buttonWithType:UIButtonTypeCustom]; [stopButton setFrame:CGRectMake(94, 0, 44, 44)]; [stopButton setImage:[UIImage imageNamed:@"stop.png"] forState:UIControlStateNormal]; [stopButton addTarget:self action:@selector(stop:) forControlEvents:UIControlEventTouchUpInside]; [subViewWithControls addSubview:stopButton]; return subViewWithControls; } </code></pre> <p>and here is the play button action:</p> <pre><code>-(void)play:(UIButton *)sender { if(sender.selected == NO){ sender.selected = YES; [self setButtonCurrentState:YES]; [self.moviePlayerController setInitialPlaybackTime:self.currentTime]; [self playMovieFile:[self localMovieURL]]; } else{ sender.selected = NO; [self setButtonCurrentState:NO]; self.currentTime = self.moviePlayerController.currentPlaybackTime; [self.moviePlayerController pause]; } } </code></pre> <p>My requirement is I need to change the play image to pause for play button once the video is stopped i.e. when user clicks stop button.I have tried the below way:</p> <pre><code>-(void)stop:(UIButton *)sender{ if (self.buttonCurrentState == YES) { [playButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal]; } self.currentTime = 0.0; [[self moviePlayerController] stop]; [self deletePlayerAndNotificationObservers]; } </code></pre> <p>It is validating the condition in stop button action,I have already debugged and tested,but the image change doesn't affect.Wonder the reason why??</p> <p>I have also tried changing the images in play button action instead of doing in <code>-(UIView *)subViewControlsView</code> method.But what happens is to my surprise,I can't see the button as the image is not set in the view method.I have tried to set up the image as play initially for control state normal and then change in play action.Now what happens is the play button doesn't turn to pause button,which is a double blow.I tried setting tags,boolean values and lot more.None of them seem to work!!!</p> <p>Can any one please suggest me a solution?</p> <p>Thanks all in advance :)</p>

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.
