ios - CFURLCreateStringByAddingPercentEscapes 在 iOS 9 中被弃用，我如何使用 "stringByAddingPercentEncodingWithAllowedCharacters"

Question

我有以下代码:

    return (NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)string, NULL, CFSTR(";:@&=+$,/?%#[]"), kCFStringEncodingUTF8);

Xcode 表示它在 iOS 9 中已弃用。那么，我该如何使用 stringByAddingPercentEncodingWithAllowedCharacters 呢？

谢谢!

试试这个

NSString *value = @"<url>";
value = [value stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
