iOS动画-定时对UIView进行翻转和抖动的方法

[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;      // 切换界面保证动画不停止      rotationAnimation.removedOnCompletion = NO;      rotationAnimation.repeatCount = 1;      [self.bindCardImageView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];    }];

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"];

CABasicAnimation* shake = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];  //设置抖动幅度  shake.fromValue = [NSNumber numberWithFloat:-0.2];  shake.toValue = [NSNumber numberWithFloat:+0.2];  shake.duration = 0.1;  shake.autoreverses = YES; //是否重复  shake.repeatCount = 3;  [itemView.iconImageView.layer addAnimation:shake forKey:@"imageView"];
