用弧覆盖设置器

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
}

启用 ARC 时我是否正确覆盖了设置器?

Did I correctly override the setter when ARC is enabled?

推荐答案

是的，这是正确的.我也花了一段时间才相信这确实是正确的做法.

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

您确实意识到，在这种情况下，覆盖不是必需的，因为您不会做比标准生成的 setter 做的更多的事情吗?仅当您向 setImageURLString: 添加更多代码时，您才需要覆盖 setter.

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.
