Question

我有以下代码：

- (IBAction)showDirectMessage:(id)sender
{
    DetailMessageViewController * dmvc = [[DetailMessageViewController alloc] init];
    dmvc.modalPresentationStyle = UIModalPresentationFormSheet;
    [self presentModalViewController:dmvc animated:YES];
}

我在这里要做的是呈现一个顶部有一个NavigationBar的视图，一个UITableView作为里面的视图。但是截至目前它只显示了UITableView。我对需要改变的事感到困惑。在我的DetailMessageViewController IB中，我拖入UINavigationController并将UITableView作为视图放入其中。但是，我将UINavigationController连接到UITableView视图..我认为这是错误的。我不知道我该怎么做。有人可以指导我吗？

Answer 1

您应该使用ViewController提供新的NavigationController。

- (IBAction)showDirectMessage:(id)sender
{
    DetailMessageViewController * dmvc = [[DetailMessageViewController alloc] init];
    UINavigationController *naviContoroller = [[UINavigationController alloc] initWithRootViewController:dmvc];
    naviContoroller.modalPresentationStyle = UIModalPresentationFormSheet;

    [self presentModalViewController:naviContoroller animated:YES];

    [naviContoroller release];
    [dmvc release];
}

Answer 2

DetailMessageViewController *dmvc=[[[DetailMessageViewController alloc]initWithNibName:@"DetailMessageViewController" bundle:nil]autorelease];    
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:dmvc]autorelease];
[navController setModalTransitionStyle:UIModalPresentationFormSheet];
[[self navigationController] presentModalViewController:navController animated:YES];
