objective-c - 如何遍历 NSString 的字符

Question

NSString *myStrings = @"abcdefghijklmnopqrstuvwxyz";

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

Answer 1

一种方法是使用简单的 for 循环:

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