Question

在我的申请中，我有4 UIViewcontrollers - A，B，C和D.

从我的UIViewController A，可以呈现UIVIewControllers B或C或D.假设，从A，我已经呈现B.然后，在B上，有两个UIButtons，点击它，我需要解雇B和现在C或解雇B和现在D.这发生成功，但是首先，在解雇B之后，A的屏幕出现，然后进入C或D.

这就是我所做的：

开启按钮按开启B，操作为：

{
    UINavigationController *controller = (UINavigationController *)self.parentViewController;
    NSLog(@"%@",[controller parentViewController]);
    UITabBarController *tabBarReference = (UITabBarController *)[controller parentViewController];

    HomePageViewController *presController = (HomePageViewController *)tabBarReference.presentingViewController;
    [presController dismissTabControllerWithHandlerWithSenderAtIndex:1];
}

在A中，我有这些方法：

-(void)dismissTabControllerWithHandlerWithSenderAtIndex:(NSInteger)index
{
    if(index == 0)
    {
        [self dismissViewControllerAnimated:NO completion:^{

            [self aboutButtonPressed:self];

        }];
    }

    else
    {
        [self dismissViewControllerAnimated:NO completion:^{

            [self settingsButtonPressed:self];

        }];
    }
}

这是我打电话的方法..

- (IBAction)settingsButtonPressed:(id)sender
{
    [self.contactUsView setHidden:YES];

    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSString *deviceType = [prefs objectForKey:@"DeviceType"];
    NSString *iOSType = [prefs objectForKey:@"iOSType"];

    if([iOSType isEqualToString:@"iOS7"])
    {
        if([deviceType isEqualToString:@"iPad"])
        {
            SettingsViewController *settingsPage = [[SettingsViewController alloc] initWithNibName:@"SettingsViewController_iPad" bundle:NULL];
            settingsPage.modalTransitionStyle = UIModalTransitionStylePartialCurl;
            [self presentViewController:settingsPage animated:YES completion:NULL];
        }

        else
        {
            SettingsViewController *settingsPage = [[SettingsViewController alloc] initWithNibName:@"SettingsViewController" bundle:NULL];
            settingsPage.modalTransitionStyle = UIModalTransitionStylePartialCurl;
            [self presentViewController:settingsPage animated:YES completion:NULL];
        }
    }

    else
    {
        if([deviceType isEqualToString:@"iPad"])
        {
            SettingsViewController *settingsPage = [[SettingsViewController alloc] initWithNibName:@"SettingsViewController_iPad_iOS6" bundle:NULL];
            settingsPage.modalTransitionStyle = UIModalTransitionStylePartialCurl;
            [self presentViewController:settingsPage animated:YES completion:NULL];
        }

        else
        {
            SettingsViewController *settingsPage = [[SettingsViewController alloc] initWithNibName:@"SettingsViewController_iOS6" bundle:NULL];
            settingsPage.modalTransitionStyle = UIModalTransitionStylePartialCurl;
            [self presentViewController:settingsPage animated:YES completion:NULL];
        }
    }
}

好的，这里： -

假设viewcontroller A是基础＆amp;它presents view controllers B或C。

实施必须解除视图控制器B或C的委托/通知。

发送代理人或发布通知后，请关闭当前的view controller without animation, i.e animation:NO。

发布此通知需要在view controller A

中听到

在这里，您将展示下一个视图控制器。

修改： -

-(void)dismissTabControllerWithHandlerWithSenderAtIndex:(NSInteger)index { if(index == 0) { [self dismissViewControllerAnimated:NO completion:nil]; [self aboutButtonPressed:self]; } else { [self dismissViewControllerAnimated:NO completion:nil]; [self settingsButtonPressed:self]; } }

解雇视图控制器并呈现另一个viewController
