本文介绍如何使用UIKit中的视图动画，包括基本属性frame、center、bounds和transform的调整方法，通过具体的Swift代码示例展示了如何实现图片的放大缩小、旋转和平移等效果，并介绍了动画效果的配置方法。

判断是否在执行动画

if(self.image.isanimation) return;

1. frame\center\bounds\transform

1> frame:能修改位置和尺寸

2> center:能修改位置

3> bounds:能修改尺寸(x\y一般都是0)以自己左上角为原点

4> transform:能修改大小尺寸旋转角度

2.transform操作图片

//    放大缩小
- (IBAction)bigAndSmall:(UIButton*)sender {
if(sender.tag== 10)
{
    CGAffineTransformtrans = self.MyView.transform;
    CGAffineTransformform = CGAffineTransformScale(trans, 1.2, 1.2);
    self.MyView.transform= form;
}else if (sender.tag== 20)
{
      CGAffineTransformtrans = self.MyView.transform;
      CGAffineTransformform = CGAffineTransformScale(trans, 0.9, 0.9);
      self.MyView.transform= form;
}
}
//    旋转
- (IBAction)rotate:(UIButton*)sender {
    CGAffineTransformtrans = self.MyView.transform;
    CGAffineTransformform = CGAffineTransformRotate(trans, M_PI_4);
    self.MyView.transform= form;

}
//    平移
- (IBAction)translation:(UIButton*)sender {
    CGAffineTransformtrans = self.MyView.transform;
    CGAffineTransformform = CGAffineTransformTranslate(trans, 0, 10);
    self.MyView.transform= form;

}
//    复位
- (IBAction)recove:(UIButton*)sender {
    self.MyView.transform= CGAffineTransformIdentity;

}

3. 动画效果代码

[UIView beginAnimations:nil context:nil];//开始动画

[UIView setAnimationDuration:2.0]; //设置时间 s

[UIViewsetAnimationRepeatCount:100];//执行次数

要执行动画的代码

[UIView commitAnimations]; //提交动画

4.block实现动画

UIView animateWithDuration:<#(NSTimeInterval)#> animations:^{
<#code#>

}

5.延迟调用

//延迟调用

[selfperformSelector:@selector(dismissViewControllerAnimated:completion:)withObject:nilafterDelay:1.0f];

6.转场动画

- (void)rightBtnAction

{

//设置动画的翻转方向

UIViewAnimationTransition transition =_listBtn.hidden? UIViewAnimationTransitionFlipFromLeft:UIViewAnimationTransitionFlipFromRight;

[UIViewanimateWithDuration:.35animations:^{

[UIViewsetAnimationTransition:transitionforView:_imagecache:YES];

    }];

    _rightBtn.hidden= !_rightBtn.hidden;
    _rightBtn1.hidden= !_rightBtn1.hidden;

}

7.实现动画左翻转然后右翻转回来

- (void)buttonAction {

     UIView *customView =self.navigationItem.rightBarButtonItem.customView;

    //切换按钮的显示
    UIButton *postButton = (UIButton*)[customView viewWithTag:100];
    UIButton *listButton = (UIButton*)[customView viewWithTag:101];
    postButton.hidden= !postButton.hidden;
    listButton.hidden= !listButton.hidden;

    //设置动画的翻转方向
    UIViewAnimationTransition transition = postButton.hidden? UIViewAnimationTransitionFlipFromLeft:UIViewAnimationTransitionFlipFromRight;

    //翻转动画
    [UIViewbeginAnimations:nilcontext:nil];
    [UIViewsetAnimationDuration:.35];

    [UIViewsetAnimationTransition:transitionforView:customViewcache:YES];

    [UIViewcommitAnimations];

}
