自定义 Push Segue 删除故事板中的导航栏和标签栏 [英] Custom Push Segue removes navigation bar and tab bar in story board
问题描述
我在自定义 Segue 中定义了以下内容，我们称之为 SegueX:
I have the following defined in a custom Segue, let us call it SegueX:
@interface SegueX : UIStoryboardSegue
@end
@implementation SegueX
- (void)perform
{
CATransition* transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
[[self.sourceViewController navigationController].view.layer addAnimation:transition forKey:kCATransition];
[[self.sourceViewController navigationController] pushViewController:[self destinationViewController] animated:NO];
}
@end
在我的故事板中，我刚刚将标准的 Push segue 更改为 SegueX.出于某种原因，这将删除我的导航栏和标签栏.此外，我在自定义转场之后在故事板中定义的所有 UIBarButtonItems 都在运行时隐藏.我该如何解决?我希望它不是这样的......
In my story board I have just changed a standard Push segue to SegueX. For some reason this will remove my navigation bar and tab bar. Furthermore all UIBarButtonItems I have defined in the story board after the custom segue are hidden at runtime. How do I fix this? I hope it is not meant to be this way...

推荐答案
当您更改转场时，导航栏和工具栏应该在故事板中消失——这是正常的.您可以将底部栏的模拟指标更改为半透明工具栏"，这会将其添加回来，因此您可以向其添加按钮(您只想更改模拟指标，而不是拖入另一个会添加第二个工具栏的工具栏)工具栏).在运行时，您仍然应该看到两个带有按钮的栏.
The navigation bar and the tool bar should disappear in the storyboard when you change the segue -- that's normal. You can change the simulated metrics for the bottom bar to "Translucent Toolbar", which will add it back, so you can add buttons to it (you only want to change the simulated metrics, not drag in another tool bar which would add a second tool bar). You should still see both bars with their buttons at run time.
