loaded the "BlueView" nib but the view outlet was not set 错误的解决办法

[UIViewController _loadViewFromNibNamed:bundle:] loaded the "BlueView" nib but the view outlet was not set.



查书才知道，没有做nib文件到xxxViewControler程序的关联，特此记录下来:



1, 打开nib文件

2, 点击"File's Owner", 按command+4,设置Class为xxxViewControler

3, 按Control+"Files's Owner"或选中File‘s Owner，点右键, 里面有个默认的IBOutlet变量view, 看一下后面有没有做关联，如果没有就拉到下面的View和视图做个关联
