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"];
以上这篇iOS动画-定时对UIView进行翻转和抖动的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持武松娱乐。
