NSMutableArray作为@property只读(NSMutableArray as @property with readonly)
假设我有这样的事情:
@property (readonly) NSMutableArray *someArray;
即使@property设置为只读,我可以修改[obj someArray]吗?
Suppose I have something like this:
@property (readonly) NSMutableArray *someArray;
Can I modify [obj someArray] even though the @property is set to readonly?
