替换字符串中的字母 [英] Replace letters in a string

问题描述

您好我有一个问题，我不知道如何解决。问题是我甚至不知道如何谷歌。我已经花了几个小时在互联网上寻找解决方案，但没有成功。情况是这样的：

Hello i have a problem that i don't know how to solve. The problem is that I even don't know how to google about it. I've already spent hours on the internet finding the solution, but didn't succeeded. The situation is like this:

我有字符串，让我们说：

I have String, lets say:

NSString *string = @"aąbcčdeęėfghiįjzž";

我的结果必须是这样的：

my result has to be like this:

NSString *string = @"aabccdeeefghiujzz";

所以如果你明白我必须这样做：

So if you understood i have to do this:

用

用c替换č

用e替换ė

用e

等等..

也许有人可以帮助我？我有一个答案，但它不是很优化，我希望有一些更方便的解决方案。

Maybe anyone could help me? i have an answer but it's not very optimized, i am hoping for some more convenient solution.

提前致谢！

推荐答案

让框架为你做转换：

NSString *blah = @"aąbcčdeęėfghiįjzž";
NSData *data = [blah dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *newblah = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(@"new: %@", newblah);

此日志：

new: aabccdeeefghiijzz
