静态库bug

错误提示： Undefined symbols for architecture i386:

                   "_OBJC_CLASS_$_MyView", referenced from:

                     objc-class-ref in ViewController.o

                    ld: symbol(s) not found for architecture i386

                     clang: error: linker command failed with exit code 1 (use -v to see invocation)

后来发现是加错了静态库，在模拟器上运行和真机上运行所加的静态库是不一样的。
