有人可以帮我弄清楚出了什么问题吗?

1 个答案:

答案 0 :(得分:2)

因为你正在使用[super dealloc]我想你的项目是非ARC的。在这种情况下,当您使用xImg创建oImg-imageNamed时,您不会保留它们(并且在-dealloc中您会释放它们。也许,您应该更好地阅读iOS中的内存管理?)。所以在-touchBegan中你正在访问被解除分配的对象,这会导致错误。改为使用

oImg = [[UIImage imageNamed:@"O copy.jpg"] retain];

您还可以通过编辑将您的项目转换为ARC - >重构 - >转换为ARC。

另外,我强烈建议使用按钮来捕捉触摸,尽量避免复制粘贴代码,并且,如NSElvis所述,使用&&而不是&
