iOS动画-定时对UIView进行翻转和抖动的方法
(翻转)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;
// 切换界面保证动画不停止
rotationAnimation.removedOnCompletion = NO;
rotationAnimation.repeatCount = 1;
[self.bindCardImageView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
}];
(翻转)方式二(这种方式较好一些):
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"];
抖动:
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"];
