這篇文章主要介紹了iOS字體抖動(dòng)動(dòng)畫的實(shí)現(xiàn)代碼，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了iOS字體抖動(dòng)的具體實(shí)現(xiàn)代碼，供大家參考，具體內(nèi)容如下

一、效果圖

二、代碼

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
 [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
 
 UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
 button.frame=CGRectMake(10, 100, 100, 200);
 button.backgroundColor=[UIColor redColor];
 [button setTitle:@"按鈕" forState:UIControlStateNormal];
 [self.view addSubview:button];
 
 //按鈕的動(dòng)畫效果
 [self buttonAnimation:button];
 
 
}

//按鈕出現(xiàn)的時(shí)候有一個(gè)動(dòng)畫效果
- (void)buttonAnimation:(UIButton *)sender
{
 CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"];
 
 CATransform3D scale1 = CATransform3DMakeScale(0.5, 0.5, 1);
 CATransform3D scale2 = CATransform3DMakeScale(1.2, 1.2, 1);
 CATransform3D scale3 = CATransform3DMakeScale(0.9, 0.9, 1);
 CATransform3D scale4 = CATransform3DMakeScale(1.0, 1.0, 1);
 
 NSArray *frameValues = [NSArray arrayWithObjects:
       [NSValue valueWithCATransform3D:scale1],
       [NSValue valueWithCATransform3D:scale2],
       [NSValue valueWithCATransform3D:scale3],
       [NSValue valueWithCATransform3D:scale4],
       nil];
 
 [animation setValues:frameValues];
 
 NSArray *frameTimes = [NSArray arrayWithObjects:
       [NSNumber numberWithFloat:0.0],
       [NSNumber numberWithFloat:0.5],
       [NSNumber numberWithFloat:0.9],
       [NSNumber numberWithFloat:1.0],
       nil];
 [animation setKeyTimes:frameTimes];
 
 animation.fillMode = kCAFillModeForwards;
 animation.duration = 0.3f;
 
 [sender.layer addAnimation:animation forKey:@"DSPopUpAnimation"];
}

以上就是本文的全部內(nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
