ios - 在更改选定的索引选项卡时关闭模态视图不起作用

Question

我有一个带有菜单的 tabBar 应用程序，该菜单通过 Model View Controller 调用。然后当你选择一个选项时。我希望它在更改 tabBAr 的 SelectedIndex 时关闭。

这是我的代码片段:

第一个标签栏 Controller :

这就是所谓的“菜单”

-(IBAction)pressedButton {

    GWDNativeViewController *secondView = [[GWDNativeViewController alloc] initWithNibName:nil bundle:nil];
    [secondView setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
    [self presentModalViewController:secondView animated:YES];
}

这是在 GWDNativeViewController(菜单) View 中关闭的代码:

-(IBAction)dismissThisView {

    //Insert code to dismiss here
    [self dismissModalViewControllerAnimated:YES];
    [(UITabBarController *)self.parentViewController setSelectedIndex:3];

}

行:

[(UITabBarController *)self.parentViewController setSelectedIndex:3];

似乎没有成功..

试试这个:

YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];

appDelegate.tabBarController.selectedIndex = 3;
