下面小編就為大家?guī)硪黄猧OS動畫-定時對UIView進行翻轉(zhuǎn)和抖動的方法。小編覺得挺不錯的，現(xiàn)在就分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

（翻轉(zhuǎn)）方式一：

[NSTimer scheduledTimerWithTimeInterval:3.f repeats:YES block:^(NSTimer * _Nonnull timer) {
      CABasicAnimation* rotationAnimation = [CABasicAnimation animation];;
      rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
      rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];
      rotationAnimation.duration = 1;
      // 切換界面保證動畫不停止
      rotationAnimation.removedOnCompletion = NO;
      rotationAnimation.repeatCount = 1;
      [self.bindCardImageView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
    }];

（翻轉(zhuǎn)）方式二（這種方式較好一些）：

CABasicAnimation *waitAnimation = [CABasicAnimation animation];
    waitAnimation.toValue = [NSNumber numberWithFloat:1.0];
    waitAnimation.duration = 3.f;
    waitAnimation.beginTime = 3.f;

    CABasicAnimation* rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
    rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];
    rotationAnimation.duration = 1.f;

    CAAnimationGroup *group = [CAAnimationGroup animation];
    group.duration = 4.f;
    group.repeatCount = CGFLOAT_MAX;
    group.removedOnCompletion = NO;

    [group setAnimations:@[waitAnimation, rotationAnimation]];

    [self.bindCardImageView.layer addAnimation:group forKey:@"bindCardImageViewAnimation"];

抖動：

CABasicAnimation* shake = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
  //設(shè)置抖動幅度
  shake.fromValue = [NSNumber numberWithFloat:-0.2];
  shake.toValue = [NSNumber numberWithFloat:+0.2];
  shake.duration = 0.1;
  shake.autoreverses = YES; //是否重復(fù)
  shake.repeatCount = 3;

  [itemView.iconImageView.layer addAnimation:shake forKey:@"imageView"];

以上這篇iOS動畫-定時對UIView進行翻轉(zhuǎn)和抖動的方法就是小編分享給大家的全部內(nèi)容了，希望能給大家一個參考，也希望大家多多支持腳本之家。
