iphone - 使用等待对话框导航到另一个ViewController

我正在尝试使用MBProgressHUD在我的应用程序中使用“等待对话框”。

我的应用程序中有一个按钮。当用户单击它时，我们导航到另一个viewController：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
ViewController2 *yourViewController = (ViewController2 *)[storyboard instantiateViewControllerWithIdentifier:@"FavoritePage"];
[self.navigationController pushViewController:yourViewController animated:YES];

如您所知，也可以从interface builder进行设置。

问题是直到下一页加载需要很短的时间，而我想在此期间显示一个“等待对话框”：

- (IBAction)navigation:(id)sender {
    [MBProgressHUD showHUDAddedTo:self.view animated:YES];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    ViewController2 *yourViewController = (ViewController2 *)[storyboard instantiateViewControllerWithIdentifier:@"FavoritePage"];
    [self.navigationController pushViewController:yourViewController animated:YES];
}

但它不起作用。

当我删除与导航相关的代码时，只需使用以下代码：

[MBProgressHUD showHUDAddedTo:self.view animated:YES];

等待对话框出现，但是当我使用导航代码和这一行时，等待对话框不显示并且导航正常。

如何使它们一起工作？

只想添加它以隐藏“等待对话框”，我也有这个：

- (void) viewDidDisappear:(BOOL)animated {
    [MBProgressHUD hideHUDForView:self.view animated:YES];
}

最佳答案

代替，

- (IBAction)navigation:(id)sender {
    [MBProgressHUD showHUDAddedTo:self.view animated:YES];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    ViewController2 *yourViewController = (ViewController2 *)[storyboard instantiateViewControllerWithIdentifier:@"FavoritePage"];
    [self.navigationController pushViewController:yourViewController animated:YES];
}

尝试，

- (IBAction)navigation:(id)sender {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    ViewController2 *yourViewController = (ViewController2 *)[storyboard instantiateViewControllerWithIdentifier:@"FavoritePage"];
    [self.navigationController pushViewController:yourViewController animated:YES];
    [MBProgressHUD showHUDAddedTo:self.navigationController.view  animated:YES];
}

否则，您需要在showHUDAddedTo的ViewController2方法中添加viewWillAppear方法。
