在我的应用程序中，我正在使用custom table view，
所以在一个单元格中有很多图像设置为server url，
还使用一个scrollview进行图像和视频显示，文本信息也在那里。所以应用程序获取内存警告和应用程序崩溃，我试图解决，但我没有解决。你有任何想法，所以帮助我。
下面是我的代码，请检查并帮助我解决此问题

尝试使用UICollectionView代替UIScrollView。
在方法InnerScrollView:jsonValue:中，您要向UIButton添加多个ImgScroll，这可能会在调用dequeueReusableCellWithIdentifier时重复使用。
在initWithStyle:reuseIdentifier:创建单元格时创建所有子视图。
或者您可以尝试在ImgScroll之前删除addSubview中的所有子视图。
