Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM enqueue:]: unrecognized selector sent to instance 0x126ea4a10'

解决方法：
在项目的“build settings” 中找到other linker flags 添加值 -ObjC，运行还是报 这个错误，改为添加值-all_load，再次运行，问题才解决了。

解决方法：
检查Build Phases->Link Binary With Libraries 是否包含了libstdc++.dylib库 或直接把libstdc++.dylib换成libstdc++.6.0.9.dylib
