POSequential Highlighting of a UILabels with sound clips

Body
copied!<p>I have been searching for a answer for this issue for a while now, and haven't had any luck.</p> <p>Here is the issue: I have four UILabels, and sound clips to go with them. I want each label to show highlighted text when it's sound clip is played.</p> <p>The problem is that only the last label is gets highlighted when I test it on simulator.</p> <p>Here are some things that I've tried:</p> <pre><code>[self playSound:@"this"]; [thisLabel setTextColor:[UIColor orangeColor]]; sleep(1); [self playSound:@"is"]; [thisLabel setTextColor:[UIColor blackColor]]; [isLabel setTextColor:[UIColor orangeColor]]; [self playSound:@"a"]; [isLabel setTextColor:[UIColor blackColor]]; [aLabel setTextColor:[UIColor orangeColor]]; [self playSound:@"word"]; [aLabel setTextColor:[UIColor blackColor]]; [currentWord setTextColor:[UIColor orangeColor]]; </code></pre> <p>This is when I discovered that only the last label would show up highlighted when I tested it in the simulator.</p> <p>The next thing I tried is putting a call to this function at the end of t he playSound function.</p> <pre><code>- (void)shiftHighlight:(NSString *)word { UILabel *currentWord = [self currentWord]; UILabel *thisLabel = [self thisLabel]; UILabel *isLabel = [self isLabel]; UILabel *aLabel = [self aLabel]; if ([word isEqualToString:@"this"]) { [thisLabel setHighlighted:YES]; [isLabel setHighlighted:NO]; [aLabel setHighlighted:NO]; [currentWord setHighlighted:NO]; } else if ([word isEqualToString:@"is"]) { [isLabel setHighlighted:YES]; [thisLabel setHighlighted:NO]; [aLabel setHighlighted:NO]; [currentWord setHighlighted:NO]; } else if ([word isEqualToString:@"a"]) { [aLabel setHighlighted:YES]; [thisLabel setHighlighted:NO]; [isLabel setHighlighted:NO]; [currentWord setHighlighted:NO]; } else { [currentWord setHighlighted:YES]; [thisLabel setHighlighted:NO]; [isLabel setHighlighted:NO]; [aLabel setHighlighted:NO]; } } </code></pre> <p>With the color of the highlighted text set as orange elsewhere. This had the same effect as the first attempt.</p> <p>Most recently I tried putting successive calls to this function:</p> <pre><code>- (void)readSection:(NSString *)section { [self playSound:section]; [self shiftHighlight:section]; } </code></pre> <p>I've also tried something with NSTimers, but that got very confusing and it seemed like I was barking up the wrong tree with them.</p> <p>Behavior is enabled on all labels.</p> <p>So, if anyone has a solution for me, or can carefully explain how to use NSTimers for this issue, I'd her very thankful.</p>
