One of my views does not display a navigation bar when it runs. From what I can see the attributes are exactly (unless I missed something) the same as other views that work properly.
None of the attributes on the view controller are set. Top Bar is Translucent nav bar.
I also checked the attributes on the Navigation Controller and they were the same, but in case I missed something I created a new one ... no difference. Bar visibility is checked along with Extend edges (top and bottom.)
I've cleaned and restarted Xcode
I haven't (intentionally) changed anything in the custom class for the view controller.
Obviously, I am missing something but what?

I am adding a search controller in my app that is part of a tab bar controller. I am trying to get the scope to always show, not just when the search bar is active. I have tried subclassing and overriding the method to always show it, and I have even tried using a UISearchBar and UISegmentedControl separate to seem like the scope is always showing. The issue with that is that the navigation bar height won't change. What would be the best/easiest way of doing this?
(also, for people who have used UISearchController, how can I get the background to extend under the status bar when the UISearchBar is active, like in the mail app)
I have a WKInterfaceMenu added to the storyboard which is working great. However, once used, I don't want the menu to appear for a second time.
Is there a way of preventing the menu from appearing?
You can definitely do this, but you need to do things a bit differently.
First off, don't set up the context menu in the storyboard. Instead, set up all the menu items programmatically. You can add and remove menu items using the addMenuItemWithImageNamed and clearAllMenuItems methods on your WKInterfaceController instance.
You want to set up all your menu items initially, then remove them in all your callback methods for each menu item. That way, they'll be there at first, and will be removed once you select one of them.
i am getting these error:
nested push animation can result in corrupted navigation bar.
Unbalanced calls to begin/end appearance transitions.
I am trying to push one view controller to another one.i am getting following issues:
on that it is not showing title while i gave it in view will appear.
if i turn back it is now showing me blank view (transparent) having that title what i was not able to see in previous view controller.
if now i again turn back, it is showing me right sequence of titles as i am popping but without content.i mean blank (transparent).*
I had the same issue, it turned out to be that I was making two repeated calls to pushViewController:, which presented the same View Controller twice, and when I was going to pop it, the content would stay but the navigation bar would do the animation. I was having this message on the log 'Unbalanced calls to begin/end appearance transitions for ...'
Xcode_5_developer_preview_6 (beta5) is the answer for this. i just installed it. they have resolved this issue which was in Xcode_5_developer_preview beta4.
Short Version:
"How do you get a simple UITable drill down UINavigationController-styled non-full-screen modal dialog on the iPad?"
Long version:
I have a very specific set of requirements that I can't seem to get working...
I have a functioning iPad program that that needs to pop up a non-full-screen modal view. This modal needs to have a navigation controller and a simple drill-down table that displays a detailed view that I can have edit some values related to the selected item in the table.
Of course I am looking to have the regular "Back" and "Delete" buttons in the Navigation Bar.
I can handle the detailed view, what I am having issues with:
Non-full-screen popup (mine is
always full screen no matter what I
try).
The Navigation controller will not display the Table View I tell it to and the navigation bar does not even have the title I assigned to it in IB.
I can't seem to get any of this working. If anyone has a step by step example of how to do this, that would be great,
~Eric
P.S. I am not afraid of doing this 100% programmatically, but all the examples I have been trying to follow (and failing at extending to my problem) use IB.
As for the fullscreen issue, you need to set modalPresentationStyle to UIModalPresentationFormSheet or UIModalPresentationPageSheet on the controller you want to present modally. I'm not sure of a way to do this through IB.
As for your navigation controller/table view, I think more information is needed to provide an answer.
I tried to solve this in so many ways but always failed.
Basically what I need is a NavigationController with a customized NavigationBar (different height and smaller back Button) which I already achieved.
This creats two problems. If I use the default NavigationBar of the NavigationController, I have a smaller NavigationBar but the views of the pushed ViewControllers still position as if the NavBar would have the usual height. If on the other hand I use my a self created NavBar and hide the default one, then the views of the pushed ViewControllers position as if I wouldn't have any NavBar at all. I don't know where to set the views frame. No matter where I try to set them, it doesn't work.
Is there any strategy without implementing an own NavigationController from scratch?
Not using nib files, dev for iphone OS 4.0 but will switch back to iphone OS 3 quite soon again.
Try using your own customized Navigation controller and setting the frame of the pushed view in its ViewWillAppear method.
Hiding the usual Navigation Controller will create problems. Its better NOT to use it completely if you do not intend to use it . But after doing that , you will have to use your customized Navigation controller in the project wheresoever.
