最简单的方法来连接NSString和int [英] Easiest way to concatenate NSString and int

问题描述

在Objective-C中有一个通用函数，我可以插入我的项目，以简化 NSString s和 int s？

Is there a general purpose function in Objective-C that I can plug into my project to simplify concatenating NSStrings and ints?

推荐答案

如果要连接多个字符串和整数，请使用NSMutableString的appendFormat。

Both answers are correct. If you want to concatenate multiple strings and integers use NSMutableString's appendFormat.

NSMutableString* aString = [NSMutableString stringWithFormat:@"String with one int %d", myInt];    // does not need to be released. Needs to be retained if you need to keep use it after the current function.
[aString appendFormat:@"... now has another int: %d", myInt];
