字符串Objective-c中的连接字符串 [英] Concatenate String in String Objective-c

问题描述

我想在字符串中放置一个字符串。基本上在伪代码中：

I want to place a string within a string. Basically in pseudo code:

"first part of string" + "(varying string)" + "third part of string"

如何在objective-c中执行此操作？有没有办法在obj-c中轻松连接？谢谢！

How can I do this in objective-c? Is there a way to easily concatenate in obj-c? Thanks!

推荐答案

是的，

NSString *str = [NSString stringWithFormat: @"first part %@ second part", varyingString];

对于连接，您可以使用 stringByAppendingString

For concatenation you can use stringByAppendingString

NSString *str = @"hello ";
str = [str stringByAppendingString:@"world"]; //str is now "hello world"

多个字符串

NSString *varyingString1 = @"hello";
NSString *varyingString2 = @"world";
NSString *str = [NSString stringWithFormat: @"%@ %@", varyingString1, varyingString2];
//str is now "hello world"
