How can I remove quotes from an NSString?
提问by Andrew
I am trying to remove quotes from something like:
我正在尝试从以下内容中删除引号：
"Hello"
“你好”
so that the string is just:
所以字符串只是：
Hello
你好

Check out Apple's docs:
查看 Apple 的文档：
You probably want:
你可能想要：
stringByReplacingOccurrencesOfString:withString:
Returns a new string in which all occurrences of a target string in the receiver are replaced by another given string.
返回一个新字符串，其中接收器中所有出现的目标字符串都被另一个给定的字符串替换。
- (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement
So, something like this should work:
所以，这样的事情应该工作：
newString = [myString stringByReplacingOccurrencesOfString:@"\"" withString:@""];

I only wanted to remove the first quote and the last quote, not the quotes within the string so here's what I did:
我只想删除第一个引号和最后一个引号，而不是字符串中的引号，所以这就是我所做的：
challengeKey = @"\"I want to \"remove\" the quotes.\"";
challengeKey = [challengeKey substringFromIndex:1];
challengeKey = [challengeKey substringToIndex:[challengeKey length] - 1];
Hope this helps others looking for the same thing. NSLog and you'll get this output:
希望这可以帮助其他人寻找同样的东西。NSLog，你会得到这个输出：
I want to "remove" the quotes.
