I think u should use UIWebView rather than UITextView, and dynamically u can
highlight the text by adding html tags and style tag around a particular string. But
for that u need to track which string or text audio is playing. Both of these operations
should be performed simultaneously,i.e., Audio Playing and attaching tags aroynd the tags.
Now if u want to fade off the color of the text after two seconds , simply call function
after delay of two seconds, in which u can change the text color back to earlier on.
To call function after delay u should go for
[self performSelector:@selector(changeTooriginalColor) withObject:nil afterDelay:2];
Anawer вашего второго вопроса:
UIWebView *wizardSpeechWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0,100,320,265)];
wizardSpeechWebView.backgroundColor = [UIColor clearColor];
wizardSpeechWebView.opaque = NO;
wizardSpeechWebView.delegate = self;
[self.view addSubview:wizardSpeechWebView];
