Unable to reproduce issue you have mentioned, Probably the issue 'll be not because of the URL or parameters you used.

This is one of the best way to handle GET web service call and parsing data from the response, here i implemented the web call with your URL and params,

// Server data fetch
- (void)getDataForCityId:(NSInteger)cityId
{
    NSMutableString *urlString = [@"http://kiascenehai.pk/rest_api/todayEvents/api-key/Of7NU7Jimh665D5G5VwO2eKO69sWv9lf/format/json/city_id/" mutableCopy];
    [urlString appendFormat:@"%d", cityId];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10.0];
    [request setHTTPMethod:@"GET"];

    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError)
     {
         if (data)
         {
             id jsonObj = [self parseJSON:data];
         }
     }];
}

// Method parses the JSON Data Received
- (id)parseJSON:(NSData *)data
{
    id jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
    return jsonData;
}

The jsonObj parsed form the response is as
