对于旧的编译器/ iOS:

// set the original frame
button.frame = CGRectMake(30, 50, 100, 100);

// animate to the new one
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.75];
button.frame = CGRectMake(10, 70, 100, 100);
[UIView commitAnimations];

对于较新的编译器/ iOS:

// set the original frame
button.frame = CGRectMake(30, 50, 100, 100);

// animate
[UIView animateWithDuration:0.75 animations:^{
    button.frame = CGRectMake(10, 70, 100, 100);
}];
