ARC和非ARC NSString初始化 [英] ARC and Non-ARC NSString Initialization

问题描述

最近，我一直在我的Objective-C / iOS程序中使用自动引用计数，并且一直享受这个功能。

Lately, I have been using Automatic Reference Counting in my Objective-C/iOS programs, and have really been enjoying the feature.

理解它是初始化 NSString 的正确方法。我看到这个方法用于ARC和非ARC项目：

One thing I don't understand about it is the proper method to initialize an NSString. I have seen this method used with both ARC and non-ARC projects:

NSString *myClassicString = [[NSString alloc] initWithFormat:@"My great non-ARC string!"];

我还发现以下方法可用于初始化 NSString 在ARC，我更喜欢它，因为方便：

I have also found that the following method can be used for initializing an NSString in ARC, and I prefer it because of the convenience:

NSString *myARCString = [NSString stringWithFormat:@"My new simple initialization string!"];

这两者之间有什么区别吗？有正确的方法吗？是否更好？

Is there any difference between these two? Is there a proper way? Is either one better?

推荐答案

两种方法是一样的。在 NSString 初始化中，无优于其他。

Both methods are the same. None is better than the other in term of NSString initialization.
