loaded the "XXXView" nib but the view outlet was not set 解决方案

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

nib没有和vc链接上，修改：

1, 在nib文件上，点击"File's Owner", 按command+4,设置Class为xxxViewControler

2, 按Control+"Files's Owner", 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
