错误:reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key icon.'

报错如下:

2016-03-11 17:11:38.452布可[1083:80957] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key icon.'


原因:这种错误一般是xib拖线删除了变量,没有在XIB中删除,(这样xib生成的XML文件中依然有相关变量)只需要在XIB中选中“icon”这个VIEW删除就可以了。
