什么是@" some string"在目标c中意味着什么？ [英] What does @"some string" mean in objective-c?

问题描述

我刚开始使用iphone开发并遇到了一些使用@somestring的示例代码

I'm just starting out with iphone development and ran across some example code that used @"somestring"

someLabel.txt = @"string of text";

为什么字符串需要'@'？我猜它是创建对象的某种快捷方式？

Why does the string need the '@'? I'm guessing it's some kind of shortcut for creating an object?

推荐答案

它创建一个带有该字符串的NSString对象，而不是标准的c char *将在没有'@'

It creates an NSString object with that string as opposed to the standard c char* that would be created without the '@'
