Question

我有一个属性：

@property（nonatomic，retain）QBChatDialog *对话框;

当我在viewWillDisappear中将其设为nil时，它会给我错误

- (void)viewWillDisappear:(BOOL)animated {

      self.dialog = nil;

}

我收到以下错误：

-[__NSArrayM removeObjectAtIndex:]: index 2147483647 beyond bounds for empty array'

即使我不使用＆＃34; removeObjectAtIndex＆＃34;。我认为这是在内部调用。

如何追踪这一点。

请建议我。怎么办？

Answer 1

错误告诉你

你有一个空/零的数组

之后你将删除一个对象项，该对象在该数组中不再存在

诀窍：快速修复搜索' removeObjectAtIndex '全部超出项目（从左上角的第3个搜索按钮）。如果找到一个/批次观察那些

Answer 2

您可能无法在removeObjectAtIndex:内拨打viewWillDisappear:，但是您在-[TWMessageBarViewController statusBarHidden]内呼叫它。看那里，我想你会找到崩溃的根源！
