去除這裏的疊加圖像是我的代碼如何添加和使用柵格單元指數
-(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];
}
請幫助我如何去除覆蓋..
