每当我在EliteQuestionScreen应用程序中没有按钮点击时，崩溃错误是
[EliteQuestionScreen performSelector:withObject:withObject:]: message sent to deallocated instance 0x7586c60
答案 0 :(得分：0)
在ScrollTestViewController.m你做：
self.opt = [[EliteQuestionScreen alloc]
initWithNibName:@"EliteQuestionScreen"
bundle:[NSBundle mainBundle]];
查看次数。
除了最后一个之外的所有内容都将被释放。最后一个保留在self.opt中。如果你试图引用其他的那些，你就会崩溃。
这里没有简单的解决方法。您正尝试将UIViewController笔尖用于其视图，这不是一个好方法。仔细查看代码，我认为您可能需要重新考虑您的架构。例如，您可能希望切换到UITableView或UICollectionView，而不是加载此视图控制器n次。
