替换 NSString 中某个索引处的字符 [英] Replace a character at a certain index in NSString

问题描述

我正在寻找一种方法来替换 NSString 特定索引处的字符.

I'm looking for a way to replace a character at a certain index of a NSString.

例如:myString = @"******";

我想用A"替换第三个*"，使字符串看起来像这样:myString = @"**A***";

I want to replace the 3rd " * " with an "A", so that the string looks like this: myString = @"**A***";

我怎样才能做到这一点?

How can I achieve this?

提前致谢

推荐答案

试试这个:

NSString *str = @"*******";
str = [str stringByReplacingCharactersInRange:NSMakeRange(3, 1) withString:@"A"];
NSLog(@"%@",str);
