如何将 NSString 转换为 C 字符串? [英] How to convert NSString to C string?

问题描述

我知道这个问题可能是重复的，但即使在本论坛上查看了一些 Google 教程和问题后，也没有人给我一个关于这个主题的体面答案.

I know that this question is a possible duplicate, but even after looking at some Google tutorials and questions even on this forum none of them gives me a decent answer about this subject.

我有:

NSString *str = @"text";

我想做类似的事情:

char cstring [512] = str;

(这只是显示了我想要做什么，在查看了 Apple 的 NSString Class Ref 之后我什至没有考虑使用它).

(this only shows what I want to do, after looking at Apple's NSString Class Ref I didn't even think about using it).

到目前为止我有:

char command [512] = [[NSString stringWithFormat:@"text"] cStringUsingEncoding:NSUTF8StringEncoding];

尽管如此，我还是会出错.

Still, with that I get errors.

有什么解决办法吗?

推荐答案

try const char *command = [str UTF8String];
