这是我的代码
-(void)gridCell:(GridCell *)gCell didSelectImageAtIndex:(NSInteger)index imagSize:(CGRect )frameSize
{
UIImage *img=[UIImage imageNamed:@"Overlay"];
UIImageView *imgView=[[UIImageView alloc]initWithFrame:frameSize];
imgView.image=img;
[_scrPage addSubview:imgView];
[self.view addSubview:_scrPage];
}
请帮我如何删除覆盖..
