我不斷收到一個錯誤,說我的表格數組是空的。這裏是我的代碼:故事板UITableview與自定義單元格 - 空陣列錯誤
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
// Set navigation bar image
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"header.png"]
forBarMetrics:UIBarMetricsDefault];
spinnerActivity = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];
spinnerActivity.hidesWhenStopped = YES;
spinnerBarButton = [[UIBarButtonItem alloc] initWithCustomView:spinnerActivity];
self.navigationItem.rightBarButtonItem = spinnerBarButton;
[spinnerActivity startAnimating];
self.testString = [[NSString alloc] init];
self.testMutableArray = [[NSMutableArray alloc] init];
self.myTableView = [[UITableView alloc] init];
[self.view addSubview:self.myTableView];
[self getMoviesInformation];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)viewDidUnload
{
[self setMenuBarButtonItem:nil];
[super viewDidUnload];
}

[self.myTableView reloadData];

return cell;

這裏的錯誤消息,我遇到:
*終止應用程序由於未捕獲的異常 'NSRangeException',原因是:「* - [__ NSArrayM objectAtIndex:]:索引0超出界限 空陣列
任何想法爲什麼我的字典總是零,我應該調整我的代碼,使其工作?我基本圖案這對這裏的例子:

任何幫助,將不勝感激。謝謝!
謝謝。將嘗試它。更新:它仍然返回相同的錯誤。 ( – jaytrixz
是單個項目或幾個json對象? –
也在cellForRow中,添加此︰if(indexPath.row
