我在NSView中有一个基于NSOutlineView的视图。当视图显示在我的应用程序中时，outlineview会不断闪烁。 awakeFromNib被重复调用，其中包含[myOutlineView reloadData]。但是，一旦我调整窗口大小（因此视图），闪烁消退并且不再调用awakeFromNib。
我认为闪烁是由awakeFromNib中重复调用reloadData引起的。我无法确定为什么连续调用awakeFromNib。我知道每次NSOutline (here)创建NSTableCellView时都会调用它，但这并不能解释为什么它会被连续调用。
由于在我调整窗口大小后这种行为会停止，我怀疑嵌入了NSOutlineview的NSScrollView，但我现在不知道如何确认这一点，或者更重要的是如何解决它。
那么有人可以就可能导致这种行为的原因给我一些指导吗？
修改
这是在awakeFromNib中断的堆栈跟踪，基于此看起来像创建一个调用awakeFromNib的NSTableCellView，但为什么这样做会持续完成？
