Just build ZKSwizzle.h and ZKSwizzle.m, then in ZKSwizzle.m, at line 293, there're 2 errors:

'retain' is unavailable: not available in automatic reference counting mode
ARC forbids explicit message send of 'retain'

1.点击项目导航文件--> 选中Targets--> 选择 Build Phases --> 展开Compile Sources
这个时候，我们看到第二列的名称为：Compiler Flags

双击你所要使用ARC的文件，并输入 -fobjc-arc，

那么现在这个文件就可以在编译时使用ARC机制进行编译了。

同上，如果想让使用ARC机制的代码不使用ARC机制，只需要输入 -fno-objc-arc
