I need to show a message that appears with animation and hide after a few seconds also with animation.
Does anyone know how this is possible?
Thank you very much for everything.

Its easy, try chaining your animations together. First fadeIn, then fadeOut. What below code does is first set alpha
to 0. Then animate the appearance of the label in 1 sec. As soon as this is done, wait for 4 seconds, then start the fadeOut animation in the same manner.
[label setText:@"some text"];
[label setAlpha:0.0];
[UIView animateWithDuration:1.0
delay:0
options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction
animations:^(void)
{
[label setAlpha:1.0];
}
completion:^(BOOL finished)
{
if(finished)
{
[UIView animateWithDuration:1.5
delay:4
options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction
animations:^(void)
{
[label setAlpha:0.0];
}
completion:^(BOOL finished)
{
if(finished)
NSLog(@"Hurray. Label fadedIn & fadedOut");
}];
}
}];
This way of chaining animation in iOS is one of the most effective ways to do so.
