标签栏在 segue 后消失 [英] Tab bar disappears after segue

问题描述

更新:

我希望这会有所帮助.a b c d 是标签栏中的按钮.viewcontroller1 由 b 分隔 --> 没有标签栏.与 viewcontroller2 相同，它与 viewcontroller1 分离

i hope this helps. a b c d are the buttons in the tabbar. viewcontroller1 is segued by b --> no tabbar. the same with viewcontroller2, which is segued from viewcontroller1

Tabbar Controller
     I
     I_____ a
     I
     I_____ b ---- viewcontoller1 
     I                   I
     I_____ c            I__viewcontroller2
     I
     I_____ d

我一直在寻找解决方案，但没有任何方法帮助我.

Ive searched for solutions, but no approaches helped me.

在我的应用程序中，我有一个标签栏控制器作为初始视图.这个标签栏有 4 个视图.我想从这些视图之一切换到另一个视图.

In my app i have as initial view a tab bar controller. this tab bar has 4 views. I want to switch from one of these views to another view.

因此我使用segues.呈现目标视图后，不再有标签栏.

Therefore im using segues. After presenting the destination view, there is no tabbar anymore.

在情节提要中使用自适应转场 --> 显示(例如推送)

In the storyboard im using adaptives segues --> show (e.g. push)

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo{
    [picker dismissViewControllerAnimated:NO completion:NULL];
    self->takenImage = image;
    double delayInSeconds = 0.5;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){

        [self performSegueWithIdentifier:@"OrtToBulldDetail" sender:self];

    });
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if ([segue.identifier isEqualToString:@"OrtToBulldDetail"]){
        BuildDetailView *editViewController =
        (BuildDetailView *)segue.destinationViewController;
        [editViewController setMyImage:takenImage];
    }
} 

我也尝试使用导航控制器，但目标视图加载了两次，并且我的状态栏与另一个状态栏重叠..

I also tried to use a navigation controller, but the destination view was load twice and my status bar was overlayed from another statusbar..

那么我的标签栏去哪里了?我怎样才能取回它?

so where does my tabbar go? How can i get it back?

推荐答案

如果您不使用导航控制器，则显示"转场会以模态方式呈现控制器，覆盖整个屏幕，包括标签栏.您应该将 b 控制器嵌入到导航控制器中，然后显示"segue 将推送到 viewcontroller1.

If you don't use a navigation controller, then a "Show" segue presents the controller modally which covers the entire screen, including the tab bar. You should embed the b controller in a navigation controller, then the "Show" segue will do a push to viewcontroller1.

I_____ UINavigationController------b ---- viewcontoller1

I_____ UINavigationController------b ---- viewcontoller1
