尝试使用以下代码显示模态视图控制器

MapViewController *mapView = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil];
    mapView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self.navigationController presentModalViewController:mapView animated:YES];
    [mapView release];

继续收到以下错误..

'UIViewControllerHierarchyInconsistency', reason: 'A view can only be associated with at most one view controller at a time! View <UIView: 0x1ed815a0; frame = (0 20; 320 460); autoresize = W+H; layer = <CALayer: 0x1ed81600>> is associated with <UIViewController: 0x1ed835a0>. Clear this association before associating this view with <MapViewController: 0x1dd947c0>.'

这是一个我几个月没碰过的旧项目,想知道什么可能导致这样的错误？

我在iOS 6 iPad中面临问题

1. 单击按钮 - >使用UITable打开popover
2. 在选择一行 - > modalviewcontroller打开.
3. 解雇modalviewcontroller(它工作正常)
4. 然后再次单击按钮,按钮单击时应用程序崩溃(第1步)

此问题仅适用于iOS 6.它在iOS 5,iOS 4.3中运行良好
