Objective-C 中连接 NSString 的快捷方式 [英] Shortcuts in Objective-C to concatenate NSStrings

问题描述

Objective-C 中是否有 (stringByAppendingString:) 字符串连接的快捷方式，或者通常使用 NSString 的快捷方式?

Are there any shortcuts to (stringByAppendingString:) string concatenation in Objective-C, or shortcuts for working with NSString in general?

例如，我想做:

NSString *myString = @"This";
NSString *test = [myString stringByAppendingString:@" is just a test"];

更像是:

string myString = "This";
string test = myString + " is just a test";

推荐答案

我能想到的两个答案... 没有一个比使用串联运算符特别愉快.

Two answers I can think of... neither is particularly as pleasant as just having a concatenation operator.

首先，使用 NSMutableString，它有一个 appendString 方法，消除了对额外临时字符串的一些需要.

First, use an NSMutableString, which has an appendString method, removing some of the need for extra temp strings.

其次，使用 NSArray 通过 componentsJoinedByString 方法进行连接.

Second, use an NSArray to concatenate via the componentsJoinedByString method.
