更改后视图控制器iOS4.3

崩溃我想知道为什么我在iOS应用程序（部署目标iOS 4.3 - xcode 4）中出现此故障。更改后视图控制器iOS4.3

我在iPad模拟器5.0到6.1中测试过，并且在我的iPad上使用iOS 4.3（但不是我的，所以我无法更新iOS，但使用旧iOS版本练习很好）会崩溃应用程序说这句话的：

terminate called after throwing an instance of 'NSException'

的选择是：

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

因为[self presentViewController:obj animated:YES completion:nil]是一个新的iOS 5的方法。你不能在iOS 4上使用它。相反，尝试拨打[self presentModalViewController:obj animated:YES]（类似的东西）
