Comment envoyer des requêtes POST et GET ?

Question

Je veux envoyer mon JSON vers une URL ( POST et GET ).

 NSMutableDictionary *JSONDict = [[NSMutableDictionary alloc] init];
[JSONDict setValue:"myValue" forKey:"myKey"];

NSData *JSONData = [NSJSONSerialization dataWithJSONObject:self options:kNilOptions error:nil];

Mon code de demande actuel ne fonctionne pas.

 NSMutableURLRequest *requestData = [[NSMutableURLRequest alloc] init];

[requestData setURL:[NSURL URLWithString:@"http://fake.url/"];];

[requestData setHTTPMethod:@"POST"];
[requestData setValue:postLength forHTTPHeaderField:@"Content-Length"];
[requestData setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[requestData setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[requestData setHTTPBody:postData];

L'utilisation de ASIHTTPRequest n'est pas une réponse responsable.

 -(void)postmethod
    {

        NSString * post =[NSString stringWithFormat:@"Email=%@&Password=%@",_txt_uname.text,_txt_pwd.text];

        NSData *postdata= [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
        NSString *postLength=[NSString stringWithFormat:@"%lu",(unsigned long)[postdata length]];
        NSMutableURLRequest *request= [[NSMutableURLRequest alloc]init];

        NSLog(@"%@",app.mainurl);

       // NSString *str=[NSString stringWithFormat:@"%@Auth/Login",app.mainurl];
        NSString *str=YOUR URL;
        [request setURL:[NSURL URLWithString:str]];
        [request setHTTPMethod:@"POST"];
        [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
        [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
        [request setHTTPBody:postdata];
        NSError *error;
        NSURLResponse *response;

        NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
        NSString *returnstring=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
        NSMutableDictionary *dict=[returnstring JSONValue];

        NSLog(@"%@",dict);

        }

-(void)GETMethod
{

    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:appurl]];
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse: nil error: nil ];
    NSString  *returnString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
    NSMutableDictionary *dict_eventalldata=[returnString JSONValue];
    NSString *success=[dict_eventalldata objectForKey:@"success"];
