- (void) customClick{NSLog(@"动态添加事件");}- (IBAction)xigua:(id)sender {NSLog(@"这里是西瓜！");//1.通过frame设置位置(+是向右和向下)和大小/** */
//    CGRect originFrame=_xigua.frame;
//    originFrame.size.width+=10;
//    originFrame.size.height+=10;
//    originFrame.origin.x+=10;
//    originFrame.origin.y+=10;
//    _xigua.frame=originFrame;//2.通过center设置位置,center是中心点/** */CGPoint centerPoint=_xigua.center;centerPoint.x+=100;centerPoint.y+=100;//方法一：头尾式，执行动画//1).开启动画,会平滑一点
//    [UIView beginAnimations:nil context:nil];
//    //2).设置动画执行时间，单位秒
//    [UIView setAnimationDuration:1];
//    _xigua.center=centerPoint;//3).提交动画 注释后，动画也可以执行
//    [UIView commitAnimations];//方法二：block方式执行动画[UIView animateWithDuration:1 animations:^{_xigua.center=centerPoint;}];//3.通过bounds设置位置(+是向左和向上)和大小/**CGRect originBounds=_xigua.bounds;originBounds.size.width+=10;originBounds.size.height+=10;originBounds.origin.x+=10;originBounds.origin.y+=10;_xigua.bounds=originBounds;*/
