erminating app due to uncaught exception 'NSUnknownKeyException', reason: '[setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key messageImage1.'
我的是因为lib组件关联IBOutlet的时候关联到了file's ower了。改成直接关联lib对应的那个class即可..
按钮出发事件的时候同样有类似解决方法的错误，错误如下
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MainTableViewController gotoThat:]: unrecognized selector sent to instance 0xb91feb0'
解决方法同上
