I am using JSON converter to convert a XML string to JSON string. I need to convert this JSON string again back to XML string. Is there any specific methods to do this?

使用此代码，您可以将 JSON 转换为 NSDictionary

With this code you can convert JSON to NSDictionary

NSString * jsonString = @"blblblblblb";
NSStringEncoding  encoding;
NSData * jsonData = [jsonString dataUsingEncoding:encoding];
NSError * error=nil;
NSDictionary * parsedData = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error];

请使用以下代码将NSDictionary转换为XML.这样您就可以将JSON转换为XML了.

Please use below code for converting NSDictionary to XML. So you can have JSON to XML converter.

+(NSString*)ConvertDictionarytoXML:(NSDictionary*)dictionary withStartElement:(NSString*)startele
{
    NSMutableString *xml = [[NSMutableString alloc] initWithString:@""];
    NSArray *arr = [dictionary allKeys];
    [xml appendString:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"];
    [xml appendString:[NSString stringWithFormat:@"<%@>",startele]];
    for(int i=0;i<[arr count];i++)
    {
        id nodeValue = [dictionary objectForKey:[arr objectAtIndex:i]];
        if([nodeValue isKindOfClass:[NSArray class]] )
        {
            if([nodeValue count]>0){
                for(int j=0;j<[nodeValue count];j++)
                {
                    id value = [nodeValue objectAtIndex:j];
                    if([ value isKindOfClass:[NSDictionary class]])
                    {       
                        [xml appendString:[NSString stringWithFormat:@"<%@>",[arr objectAtIndex:i]]];
                        [xml appendString:[NSString stringWithFormat:@"%@",[value objectForKey:@"text"]]];
                        [xml appendString:[NSString stringWithFormat:@"</%@>",[arr objectAtIndex:i]]];
                    }

                }
            }
        }
        else if([nodeValue isKindOfClass:[NSDictionary class]])
        {
            [xml appendString:[NSString stringWithFormat:@"<%@>",[arr objectAtIndex:i]]];
            if([[nodeValue objectForKey:@"Id"] isKindOfClass:[NSString class]])
                [xml appendString:[NSString stringWithFormat:@"%@",[nodeValue objectForKey:@"Id"]]]; 
            else
                [xml appendString:[NSString stringWithFormat:@"%@",[[nodeValue objectForKey:@"Id"] objectForKey:@"text"]]]; 
            [xml appendString:[NSString stringWithFormat:@"</%@>",[arr objectAtIndex:i]]];
        }

        else
        {
            if([nodeValue length]>0){
                [xml appendString:[NSString stringWithFormat:@"<%@>",[arr objectAtIndex:i]]];
                [xml appendString:[NSString stringWithFormat:@"%@",[dictionary objectForKey:[arr objectAtIndex:i]]]]; 
                [xml appendString:[NSString stringWithFormat:@"</%@>",[arr objectAtIndex:i]]];
            }
        }
    }

    [xml appendString:[NSString stringWithFormat:@"</%@>",startele]];
    NSString *finalxml=[xml stringByReplacingOccurrencesOfString:@"&" withString:@"&amp;"];
//  NSLog(@"%@",xml);
    return finalxml;
}
