用弧覆盖setter [英] Override setter with arc

问题描述

@interface Article : NSObject 

@property (nonatomic, strong) NSString *imageURLString;

@end


@implementation Class

@synthesize imageURLString = _imageURLString;

- (void)setImageURLString:(NSString *)imageURLString {
    _imageURLString = imageURLString;
    //do something else
}

我是否正确覆盖了setter ARC已启用？

Did I correctly override the setter when ARC is enabled?

推荐答案

是的，这是正确的。还花了一些时间来相信这确实是正确的事情。

Yes, this is correct. Also took me a while to trust that this is indeed the right thing to do.

你知道在这种情况下，你不需要覆盖，因为你没有做标准生成的setter会做多吗？只有当您向 setImageURLString：添加更多代码时，才需要覆盖设置器。

You do realize that in this case, the override is not necessary as you don't do more than the standard generated setter would do? Only if you add more code to setImageURLString: would you need to override the setter.
