You can use UIView animation.
Here is simple implementation:

// to hide
[UIView animateWithDuration:0.5
    delay:1.0
    options: UIViewAnimationCurveEaseOut
    animations:^{
        myButton.alpha = 0.0
    } 
    completion:^(BOOL finished){
        NSLog(@"Done!");
    }];

// to show (implement in another method)
[UIView animateWithDuration:0.5
    delay:1.0
    options: UIViewAnimationCurveEaseOut
    animations:^{
        myButton.alpha = 1.0;
    } 
    completion:^(BOOL finished){
        NSLog(@"Done!");
    }];

Here is a good tutorial for this: How To Use UIView Animation Tutorial

You might want to take a look at the documentation too: UIView Class Reference

There are also similar QA’s in this website: e.g. How can I animate a UIButton Alpha property
