LazyFadeInView is a cool way to animate the apperance of a label. This effect is a clone of Secret app.
To use LazyFadeInView, create a LazyFadeInView and add it to your view. It will animate to show up once it's text is set.
An example of making a lazy fade in view:
LazyFadeInView *fadeInView = [[LazyFadeInView alloc] initWithFrame:CGRectMake(20, 120, 280, 200)];
self.fadeInView.text = @"Stray birds of summer come to my window to sing and fly away.";
[self.view addSubview:self.fadeInView];
