Xcode" - [UIViewController _loadViewFromNibNamed:bundle:]加载了笔尖,但未设置视图插座." 错误

Question

我正在使用Xcode 4,当我运行我的应用程序时,第一个屏幕无法加载.它在模拟器和设备上失败.我已经搜索了答案,他们都说要确保我已经将文件所有者中的圈子拖到了正确的视图中.对不起,我不记得事情的名字,我是Xcode的新手.我把圆圈拖到正确的视图并尝试了很多东西,但没有一个能够工作.我能做错什么？

这是完整的错误:

Answer 1

你确定你有一个UIView(或子类)分配给PonyboardViewController的"view"属性？右键单击xib左侧窗格中的"File Owner"以获取PonyboardViewController并验证是否设置了"view"插座.

如果没有,请将其设置为视图!
