1.水平晃动（登录失败，请求错误）
CAKeyframeAnimation *keyframeAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform.translation.x"];
keyframeAnimation.values = @[@-5, @0, @5, @0];
keyframeAnimation.repeatCount = 3;
keyframeAnimation.duration = 0.1;
[SomeView.layer addAnimation:keyframeAnimation forKey:nil];
2.抖动效果（删除控件）
#define angelToRandian(x) ((x)/180.0 * M_PI)
CAKeyframeAnimation *keyframeAnimation = [CAKeyframeAnimation animation];
keyframeAnimation.keyPath = @"transform.rotation";
keyframeAnimation.values = @[@(angelToRandian(-1.5)),@(angelToRandian(1.5)),@(angelToRandian(-1.5))];
keyframeAnimation.repeatCount = MAXFLOAT;
keyframeAnimation.duration = 0.2;
[SomeView.layer addAnimation:keyframeAnimation forKey:nil];`
3.弹出、缩小隐藏效果（自定义一个视图，在设置其隐藏属时触发动画）
// 自定义初始化方法
- (instancetype)init {
if (self = [super init]) {
// 初始化视图
[self initViews];
}
return self;
}
// 初始化视图
- (void)initViews {
// 这里创建了三个button
_qqLoginBtn = [[UIButton alloc] initWithFrame:CGRectMake(15, 10, 80, 80)];
[_qqLoginBtn setImage:[UIImage imageNamed:@"Icon_qq.png"] forState:UIControlStateNormal];
[self addSubview:_qqLoginBtn];
_weChatLoginBtn = [[UIButton alloc] initWithFrame:CGRectMake(110, 10, 80, 80)];
[_weChatLoginBtn setImage:[UIImage imageNamed:@"Icon_weChat.png"] forState:UIControlStateNormal];
[self addSubview:_weChatLoginBtn];
_sinaLoginBtn = [[UIButton alloc] initWithFrame:CGRectMake(205, 10, 80, 80)];
[_sinaLoginBtn setImage:[UIImage imageNamed:@"Icon_sina.png"] forState:UIControlStateNormal];
[self addSubview:_sinaLoginBtn];
}
// 设置出现、隐藏动画
- (void)setHidden:(BOOL)hidden {
if (hidden) {
// 隐藏动画
[UIView animateWithDuration:.35 delay:0 usingSpringWithDamping:1 initialSpringVelocity:30 options:UIViewAnimationOptionCurveEaseInOut animations:^{
_qqLoginBtn.transform = CGAffineTransformMakeScale(0.01, 0.01);
_weChatLoginBtn.transform = CGAffineTransformMakeScale(0.01, 0.01);
_sinaLoginBtn.transform = CGAffineTransformMakeScale(0.01, 0.01);
} completion:^(BOOL finished) {
[super setHidden:hidden];
}];
}else {
// 显示动画
[super setHidden:hidden];
[UIView animateWithDuration:.35 delay:0 usingSpringWithDamping:0.5 initialSpringVelocity:10 options:UIViewAnimationOptionCurveEaseInOut animations:^{
_qqLoginBtn.transform = CGAffineTransformMakeScale(1, 1);
_weChatLoginBtn.transform = CGAffineTransformMakeScale(1, 1);
_sinaLoginBtn.transform = CGAffineTransformMakeScale(1, 1);
} completion:nil];
}
}
