使用UITabbar的UISplitView

Question

I have a strange one that I can not seem to fix. I am currently working on updating my app to iOS7. This all worked in iOS6. It is an universal app and thus uses same xib files. However the iPad uses UISplitViews on some. Like I said, this all worked in iOS6 oh this all works on the iPhone too.

The problem is a grey bar at the bottom. I changed the tab bar to be opaque to move views up properly as i had some UI clipped to bottom of views and that went underneath the tab bar, sidetracked there. But if i set it back to translucent bar, it goes underneath but stretched properly. if i dont, it adds a bar. Other tabs work fine when NOT using splitview.

The UISplitviewController is added programmatically.

See attached image for better description.

This I have tried:

• Added autoresize on splitview
• Checked xib for subviews in the splitviews to have auto resize
• Tried to force splitview to be screen bounds
• Removed clips to bounds on all views
• Removed autoresize subviews

Any ideas would be welcomed.

Thank you all.

UPDATE:

setting the background colour the uisplitview, it does colour the bar black. So the uisplitview is definitely stretching to it.

Answer 1

我将UISplitViewController子类化，并将下面的行添加到viewDidLoad并修复了灰线。

self.extendedLayoutIncludesOpaqueBars = YES;

I believe I have found an alternative solution for you. I have had the exact same problem, mostly because we are both doing something against Apple's Guidelines which is having a SplitViewController nested within a Tabbar controller (SplitView should be the root view). This was okay in iOS 5/6, but now in iOS 7 there are far too many side effects to achieve this.

The reason you see your view stretch completely when you set the bar to be translucent is because the bar is NOT taken into account when drawing the view. When you set translucent to false, it is then taken into account of the view and you will see that grey bar there because that's your view pretending there's a tabbar at the bottom of the screen.

And as always, a SplitViewcontroller's height cannot be changed, as it is determined by the visible window height.

I tried everything you did and then some. The real solution came from using a third-party Split View Controller.

I recommend switching over to https://github.com/mattgemmell/MGSplitViewController . This split view controller is actually one large View with container views living inside of it. Because of this, you avoid all the side effects of putting an actual split view controller within a tab bar.

If that doesn't float your boat, you could create your own solution which follows the same idea of having one UIViewController with two container views contained in it, though the people behind MGSplitViewController did a good job of that already.

This was the only way I was able to solve this issue, let me know if you find an alternative.

我没有为UISplitViewController创建子类， UISplitViewController在我的master的viewDidLoad上添加了这段代码：

self.splitViewController?.extendedLayoutIncludesOpaqueBars = true

Answer 4

For the controller that is the detail view of UISplitViewController you just do this:

-(UITabBarController*)tabBarController{
    return nil;
}
