更改後視圖控制器iOS4.3

崩潰我想知道爲什麼我在iOS應用程序（部署目標iOS 4.3 - xcode 4）中出現此故障。更改後視圖控制器iOS4.3

我在iPad模擬器5.0到6.1中測試過，並且在我的iPad上使用iOS 4.3（但不是我的，所以我無法更新iOS，但使用舊iOS版本練習很好）會崩潰應用程序說這句話的：

terminate called after throwing an instance of 'NSException'

的選擇是：

- (IBAction) saltarConfiguracion: (id)sender 
{ 
    configuracionViewController *obj = [[configuracionViewController alloc]initWithNibName:@"configuracionViewController" bundle:nil]; 
    [self presentViewController:obj animated:YES completion:nil]; 
}

因爲[self presentViewController:obj animated:YES completion:nil]是一個新的iOS 5的方法。你不能在iOS 4上使用它。相反，嘗試撥打[self presentModalViewController:obj animated:YES]（類似的東西）
