Difficulty chaining two UIView animations - objective-c

Question

Here's what I'm trying to accomplish.
A UILabel will appear on screen at 100% alpha and move up 80pts using a UIView animation. As soon as that animation ends, I want it to continue 80pts higher while fading out to alpha 0. I want these two animations to appear as one seamless animation.
I thought maybe I could do this with a UIView animation and then put a second UIView animation in the completion block as shown below. However, there appears to be a delay before the completion block is executed which prevents the two animations from appearing seamless.
Can anyone tell me the best way to do what I'm trying to do?
Thanks!
[UIView animateWithDuration:1.2 delay:0 options:UIViewAnimationCurveLinear animations:^{
myLabel.center = endPoint;
}
completion:^(BOOL finished) {
[UIView animateWithDuration:1.2 delay:0 options:UIViewAnimationCurveLinear animations:^{
myLabel.center = endPoint2;
myLabel.alpha = 0;
}
completion:^(BOOL finished) {
NSLog(#"animations complete");
}];
}];

This should work. I see no reason why not. Just a small addition, check for animation completion in finished block. As this will take care of any errors during animation. Also if you are planning to make this UILabel tappable then you need to make it so by setting the flag UIViewAnimationOptionAllowUserInteraction.
[UIView animateWithDuration:1.2 delay:0 options:UIViewAnimationCurveLinear | UIViewAnimationOptionAllowUserInteraction animations:^{
myLabel.center = endPoint;
myLabel.alpha = 1;
}
completion:^(BOOL finished) {
if(finished){
[UIView animateWithDuration:1.2 delay:0 options:UIViewAnimationCurveLinear | UIViewAnimationOptionAllowUserInteraction animations:^{
myLabel.center = endPoint2;
myLabel.alpha = 0;
}
completion:^(BOOL finished) {
NSLog(#"animations complete");
}];
}
}];
