如何在iPhone上连接两个字符串？ [英] How to concatenate two strings on iPhone?

问题描述

如何将字符串Hello和字符串World连接到HelloWorld？看起来像+不起作用。

How to connect string "Hello" and string "World" to "HelloWorld"? Looks like "+" doesn't work.

推荐答案

NSString *string = [NSString stringWithFormat:@"%@%@", @"Hello", @"World"];
NSLog(@"%@", string);

这应该可以解决问题，虽然我确信有更好的方法可以做到这一点，只需要记忆我也必须说这是未经测试的所以请原谅我。最好的办法是找到NSString的stringWithFormat文档。

That should do the trick, although I am sure there is a better way to do this, just out of memory. I also must say this is untested so forgive me. Best thing is to find the stringWithFormat documentation for NSString.
