How to set NSString value to NSMutable dictionary?

I am implementing web-service APIs, data content type is of JSON. The body of the request should be in a string format i.e in double quotes but when I set it in a dictionary, I get the below result. Could anyone help me to set the NSString as string value in dictionary.

 NSMutableDictionary *reqParams = [NSMutableDictionary new]; 
[reqParams setObject:@"Data.SourceStreamRequest"forKey:@"_type"]; 

NSMutableDictionary *reqParams1 = [NSMutableDictionary new];  
[reqParams1 setObject:@"newmjpegdataSession"forKey:@"_type"];
       NSLog(@"%@:%@",reqParams,reqParams1);

Output

{
    "_type" = "Data.SourceStreamRequest";
}:{
    "_type" = newmjpegdataSession;
}

Could anyone help me to figure out the reason why ,the dictionary values are shown with double quotes and without double quotes. Thank you

Use NSJSONSerialization to serialize your dictionary. Try this:

NSDictionary *jsonDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"_type", @"Data.SourceStreamRequest",
                                @"_type", @"newmjpegdataSession", nil];

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonDictionary options:NSJSONWritingPrettyPrinted error:&error];
NSString *resultAsString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(@"json:\n%@", resultAsString);

Output:

json: { "newmjpegdataSession" : "_type", "Data.SourceStreamRequest" : "_type" }
