UIView 动画

//第一种动画方式

- (void) first_animations

{

    [UIView beginAnimations:nilcontext:nil]; //启动动画动作

    [UIView setAnimationRepeatCount:1];//设置是否重复播放

    [UIView setAnimationDuration:1];//设置动画持续时间

    [UIView setAnimationCurve:UIViewAnimationCurveEaseIn];//动画曲线,具体的应用 ,可以经过实验检测

    [UIView setAnimationDelegate:self];//动画块的某个方法(最下方),委托到本类的实例

    [UIView setAnimationDidStopSelector:@selector(resetView)];//动画结束后去执行的方法

    

    CGAffineTransform oneTransform = CGAffineTransformRotate(self.animatView.transform, degreesToRadian(180));//进行  CGAffineTransform 方式的动作(旋转拉伸等等)===>(对于CGAffineTransform 可以另外开辟一个关于CGAffineTransform使用详情的文章进行专门介绍 )

    

   CGAffineTransform twoTransform = CGAffineTransformTranslate(self.animatView.transform,0,-100);

   CGAffineTransform newTransform =CGAffineTransformConcat(oneTransform, twoTransform);

    [self.animatView setTransform:newTransform];

    [UIViewcommitAnimations];//有些网友说,这是动画结束.起始经过本人尝试试验.其实应该是,执行上方定义的动画块内容.

}
