/**
 以下系列宏用于在 Category 里添加 property 时，可以在 @implementation 里一句代码完成 getter/setter 的声明。暂不支持在 getter/setter 里添加自定义的逻辑，需要自定义的情况请继续使用 Code Snippet 生成的代码。
 使用方式：
 @code
 @interface NSObject (CategoryName)
 @property(nonatomic, strong) type *strongObj;
 @property(nonatomic, weak) type *weakObj;
 @property(nonatomic, assign) CGRect rectValue;
 @end
 
 @implementation NSObject (CategoryName)
 
 // 注意 setter 不需要带冒号
 QMUISynthesizeIdStrongProperty(strongObj, setStrongObj)
 QMUISynthesizeIdWeakProperty(weakObj, setWeakObj)
 QMUISynthesizeCGRectProperty(rectValue, setRectValue)
 
 @end
 @endcode
