首先要在framework中引入QuatrtzCore.framework,在標頭檔案中需要

#import <QuartzCore/QuartzCore.h>

CATransition *animation = [CATransition animation];
    [animation setDuration:1.25f]; 
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; 
    [animation setType:@"cube"];
    [animation setSubtype: kCATransitionFromBottom];
    CGRect rect = [text frame];
    CGRect rect1=[btn frame];
    
    [btn setFrame:rect1];
    [text setFrame:rect];
    if([text isHidden]){
        [text setHidden:NO];
    }else{
        [text setHidden:YES]; 
    }
    
    [UIView commitAnimations];
    [text.layer addAnimation:animation forKey:@"Reveal"];
