    1、Automatic Preferred Max Layout Width is not available on iOS versions prior to 8.0

    解决办法:Xib中选中某个Controller-》Show the file inspector -> Interfaces Builder Document -> Builds for ->ios8以上(但是做好的布局需要在ios7以上验证)

    2、Storyboard:Scene is unreachable due to lack of entry points and does not have an identifier for runtime access

    解决办法: 是因为在storyboard中的某个controller没有设置storyboardID的原因,给Controller添加一个storyboardID就行了

    解决办法:  转换成对应的数据类型

    解决办法:在storyboard或xib中选中对应的controller->NavigationItem-》 Left/Right Bar Button Items ->选中某个Bar Button Item——》右侧Style-》Plain改为Bordered
