    //如何动态添加控件
    //1.new 一个按钮
    UIButton *uibutton=[[UIButton alloc]init];
    //2.设置不同状态下标题及颜色
    [uibutton setTitle:@"hello,world" forState:UIControlStateNormal];
    [uibutton setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    [uibutton setTitle:@"hello,china" forState:UIControlStateHighlighted];
    [uibutton setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];
    //3.设置不同状态下背景图片
    UIImage *uiImageNormal=[UIImage imageNamed:@"star"];
    [uibutton setBackgroundImage:uiImageNormal forState:UIControlStateNormal];
    UIImage *uiImageHignlighted=[UIImage imageNamed:@"diamond"];
    [uibutton setBackgroundImage:uiImageHignlighted forState:UIControlStateHighlighted];

    //4.设置坐标及长和宽
    CGRect rect=CGRectMake(10, 20, 100, 100);
    uibutton.frame=rect;
    
    //5.添加按钮事件
    [uibutton addTarget:self action:@selector(customClick) forControlEvents:UIControlEventTouchUpInside];
    //6.添加到父视图
    [self.view addSubview:uibutton];

}
- (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;
     */
