View的放大->旋转->还原动画
以UIButton为例,创建一个类，继承于UIButton
/*页面的创建用storyboard*/
.h文件
@interface PTSRecommendButton : UIButton
- (void)viewTransform;
@end
.m文件
@implementation PTSRecommendButton
- (void)viewTransform {
//
[self.layer setAnchorPoint:CGPointMake(1, 0.5)];
CGRect btnFrame = self.frame;
//设置中心点 AnchorPoint默认是0.5
btnFrame.origin.x += btnFrame.size.width / 2 ;
self.frame = btnFrame;
//放大
[UIView transitionWithView:self duration:0.5 options:UIViewAnimationOptionAllowUserInteraction animations:^{
//因为是button在动画之行的过程点击如果没有页面跳转的操作。要设置不能狗被点击 否则会引起动画方法的覆盖
//self.userInteractionEnabled = NO;
self.transform = CGAffineTransformMakeScale(1.2, 1.2);
} completion:^(BOOL finished) {
//还原中心点
[self.layer setAnchorPoint:CGPointMake(0.5, 0.5)];
CGRect btnFrame = self.frame;
btnFrame.origin.x -= btnFrame.size.width / 2 ;
self.frame = btnFrame;
//旋转
[UIView transitionWithView:self duration:0.25 options:UIViewAnimationOptionAllowUserInteraction animations:^{
//
self.transform = CGAffineTransformRotate(self.transform, M_PI*0.05);
} completion:^(BOOL finished) {
//反向旋转
[UIView transitionWithView:self duration:0.5 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.transform = CGAffineTransformRotate(self.transform, -M_PI*0.1);
} completion:^(BOOL finished) {
//回到最初旋转状态
[UIView transitionWithView:self duration:0.25 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.transform = CGAffineTransformRotate(self.transform, M_PI*0.05);
} completion:^(BOOL finished) {
//中心点还原
[self.layer setAnchorPoint:CGPointMake(1, 0.5)];
CGRect btnFrame = self.frame;
btnFrame.origin.x += btnFrame.size.width / 2 ;
self.frame = btnFrame;
//恢复初始的状态
[UIView transitionWithView:self duration:0.5 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished) {
[self.layer setAnchorPoint:CGPointMake(.5, 0.5)];
CGRect btnFrame = self.frame;
//设置中心点 AnchorPoint默认是0.5
btnFrame.origin.x -= btnFrame.size.width / 2 ;
self.frame = btnFrame;
//self.userInteractionEnabled = YES ;
}];
}];
}];
}];
}];
}
