iOS URL编码

    1.URL编码

    NSString *encodeURL = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    2.URL解码

    NSString *decodeURL = [url stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    ios 9.0中已经替换此方法

    NSString *encodedURL = [url stringByAddingPercentEncodingWithAllowedCharacters:(nonnull NSCharacterSet *)];
    NSString *decodedURL = [url stringByRemovingPercentEncoding];

    • (NSString )stringByAddingPercentEscapesUsingEncodingExt:(NSStringEncoding)enc stringWith:(NSString )str
      {
      if([str respondsToSelector:@selector(stringByAddingPercentEncodingWithAllowedCharacters:)] == YES)
      {
      NSCharacterSet
      set = [[NSCharacterSet characterSetWithCharactersInString:@"!
      '();:@&=+$,/?%#[]"] invertedSet];
      return [str stringByAddingPercentEncodingWithAllowedCharacters:set];
      }
      else
      {

    pragma clang diagnostic push

    pragma clang diagnostic ignored "-Wdeprecated-declarations"

        //        NSString * newString = (__bridge_transfer NSString *)
        NSString * newString = ( NSString *)
        CFURLCreateStringByAddingPercentEscapes(NULL,
                                                (__bridge CFStringRef)str,
                                                NULL,
                                                (CFStringRef)@"!*'();:@&=+$,/?%#[]",
                                                CFStringConvertNSStringEncodingToEncoding(enc));
    

    pragma clang diagnostic pop

        return newString;
    }
    

    }
