如何遍历NSString的字符 [英] How to iterate through the characters of an NSString

问题描述

NSString *myStrings = @"abcdefghijklmnopqrstuvwxyz";

如何在Objective-C for循环中迭代每个字母(a，b，c，d，e等)?

How could I iterate each of the letters (a, b, c, d, e, etc..) in an Objective-C for loop?

推荐答案

一种方法是使用简单的for循环:

One way is to use a simple for-loop:

for (NSInteger charIdx=0; charIdx<myStrings.length; charIdx++)
    // Do something with character at index charIdx, for example:
    NSLog(@"%C", [myStrings characterAtIndex:charIdx]);
