之前的一个iOS项目，编译出错：
AppDelegate.m:98:10: No visible @interface for ‘OLCMigrator’ declares the selector ‘makeTable:withTableVersion:’
搜：
No visible interface for OLCMigrator declares the selector makeTable withTableVersion
重新更新了下库：

［总结］
－》后来证实,好像是由于此处所涉及到的库OLCOrm，在最开始的pod update安装的可能有问题
－》Xcode中的Podfile中的现实OLCOrm异常的红色了：
导致此处的无法正常使用。
－》换了另外一个项目，正常安装了OLCOrm：
就可以正常编译了。
－》以后再遇到类似问题，可以考虑：
重新得到干净的代码，然后
pod update
确保正常
然后再去项目中，确保
Xcode中的Podfile中，所有的库，都是正常的，没有红色的
然后再去编译，估计就可以正常编译了。
