 NSMutableString *params = [NSMutableString string];
            NSString *screenWidth = [NSString stringWithFormat:@"%f", SCREEN_WIDTH];
            [params appendFormat:@"ws_key=%@&", WS_KEY];
            [params appendFormat:@"id_lang=%@&", [preferences objectForKey:@"id_lang"]];
            [params appendFormat:@"id_currency=%@&", [preferences objectForKey:@"id_currency"]];
            [params appendFormat:@"width=%@&", screenWidth];

NSString *urlString = [NSString stringWithFormat:@"%@%@?%@",BaseDomain,@"...",params];
NSMutableURLRequest *request1 =
        [NSMutableURLRequest requestWithURL:[NSURL
                                             URLWithString:[NSString stringWithFormat:@"%@?%@",urlString,params]]
                                cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
                            timeoutInterval:10
         ];
        [request1 setHTTPMethod: @"GET"];
        NSError *requestError = nil;
        NSURLResponse *urlResponse = nil;
        NSData *response =
        [NSURLConnection sendSynchronousRequest:request1
                              returningResponse:&urlResponse error:&requestError];

NSMutableString *params = [NSMutableString string];

NSString *screenWidth = [NSString stringWithFormat:@"%f", SCREEN_WIDTH];

[params appendFormat:@"ws_key=%@&", WS_KEY];

[params appendFormat:@"id_lang=%@&", [preferences objectForKey:@"id_lang"]];

[params appendFormat:@"id_currency=%@&", [preferences objectForKey:@"id_currency"]];

[params appendFormat:@"width=%@&", screenWidth];

NSString *urlString = [NSString stringWithFormat:@"%@%@?%@",BaseDomain,@"...",params];

NSMutableURLRequest *request1 =

[NSMutableURLRequest requestWithURL:[NSURL

URLWithString:[NSString stringWithFormat:@"%@?%@",urlString,params]]

cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData

timeoutInterval:10

];

[request1 setHTTPMethod: @"GET"];

NSError *requestError = nil;

NSURLResponse *urlResponse = nil;

NSData *response =

[NSURLConnection sendSynchronousRequest:request1

returningResponse:&urlResponse error:&requestError];
