Im trying to create a UINavigationBar using storyboard but the UINavigationBar is not occupying the entire screen.
Following is the screen shot of my storyboard.
In storyboard, it appears to occupy full screen width but in my device, the width is not full. How can I sort this out?
select your viewController and go to XCode Menu - > Editor -> select Navigation Controller ,
for example
you get the output of
it works fine for any layout patterns
firstly you have to disable size classes and auto layout in the file inspecter for your view after then set your navigation bar property like as shown in screenshot. It will be applicable for all the devices.
1- Select your element.
2- Click triangle button at bottom right.
3- Click Add Missing Constraints
use autoresizing selecting your NavigationBar:-

I am doing autolayout works in Storyboard and previewing the result in Assistant Editor > Preview
How can I show navigation bar in the preview?
Take a dummy view and give its height equals to the navigation bar height. (navigation bar height remain same in each device). when u done ur pixel perfection than uncheck installed from attribute inspector of that view or just remove the view.
I suggest another way - just use top constraint, while you container view will have y = 0, you can set top constraint to 44px, in this case you will see warning, but all stuff at your screen will be at the same positions, but preview will display your screen like you have navigation bar. When everything is ok, just set top constraint to 0. I guess this solution is really convenient.
I added a UINavigationBar to a detail controller scene, but when I run my app the UINavigationBar does not appear. Why is it doing this ? I have the custom class set to the controller I want it too, but its not appearing, here is a screenshot.
but when I run this app, I dont see the "Title" bar or anything.
To add constraints select your navigation bar and click in the icon as in the picture.
uncheck "constrain to margins" as you want the navigation bar to snap in the boards of the screen, select the up and left red dots lines and add the value 0 to the drop boxes, meaning 0 pixels from the left and top of the screen.
Select Update frames and click in add constraints.
I can see in your screenshot you have other screen with problems (red icon next to the view controller) you should also fix that, click in the icon for more details about the error/warning
I am not sure if I understand what you are trying to do, but try this,
Select the detail view and go to the xCode menu and select editor->Embed in-> Navigation Controller.
I hope it helps
Add constraints to your navigation bar. However, IcaroNZ suggested the best way for navigation
I have a web view inside a tab bar controller. The problem is when using the web view, the content goes behind the tab bar and I cannot scroll to the bottom of the page. How do I resolve this?
Here is how everything is setup in Xcode
If you are using AutoLayout set the constraints of the UIWebView so that it is attached to all the sides.
Edit: Instructions
Select the UIWebView
Select the icon shown in the picture below
Unselect the Checkbox for "Constrain to Margins" because we want to constrain to neighbor
Set the numbers around the center square to 0's
Click the icons that are between the middle square and the numbers you just changed
Click Add Constraints
I have a screen that doesn't fit into a 3.5 inch phone screen. In iOS 6 I had the contents of the screen in a scroll view, but in iOS 7 that option is constantly grayed out.
Here is the screen shot
Would anyone know how to add the scrolling to my screen in ios 7?
Thank you!
Second screen shot with the scroll view.
Rather than selecting the entire view controller, you need to have a view selected. The options in Editor -> Embed In are contextual and since you have then entire view controller selected, your only options are to embed the whole VC within a Navigation Controller or a Tab Bar Controller.
If you can't get the right selection by clicking within Interface Builder, try expanding the outline view and selecting your view. Then try to embed your view within a scrollview.
Note that your root view must be a UIView, so you won't be able to embed the root view in a scrollview because that would put a scroll view at the root.
Three problems I ran into that I hope can help:
1) Make sure "Safe Area", or other object that shouldn't be there, isn't one of the objects selected in your view while trying to embed. For a simple test select just one simple object like a textfield or label and see if the Editor -> Embed In is still greyed out and work backwards if you have to.
2) You're going from View > Content to View > ScrollView > View > Content. So after embedding in a scrollview, embed in a view.
3) Once embedded make sure your scrollview is less than your content size, or it won't scroll: https://stackoverflow.com/a/28146729/1323357
Using XCode 5, downloaded today. iOS 7. When I run app the table view header appears underneath the navigation bar, I don't mind it scrolling underneath the navbar but I'd like for it to appear unobstructed initially. I am trying to figure out how to use the topLayoutGuide mentioned in the iOS 7 transition guide, which says you can set a constraint relative to it, but doesn't explain how.
Anyone know?

Just realized that my storyboard was still set to XCode 4.6
You have to go to the File Inspector (icon that looks like a file icon in the right navigation panel in Xcode) and then under "Interface Builder Document" where it says "Opens in" change to Default (5.0) and / or "View as" iOS 7.0 and Later
Then your IB document will show the guides inside the left hand navigation panel under the view controller
Often if you select the view, and click the "Pin" button at the bottom right, pin the vertical spacing, and the dropdown will have an option to use the topLayoutGuide
In my Storyboard, was still have trouble getting my UITableView to pin the vertical spacing between the top of the table view and the top layout guide. Every time I control-dragged I would get it pinning to the bottom of the table view instead of the bottom. But then I tried manually dragging the table view so that it appeared below the nav bar in IB and then control-dragged and the vertical spacing finally worked.
I had the same problem, and in Storyboard when I set the top bar to Opaque the top of the scrollView changed so that it wasn't obscured by the nav bar. Makes sense, but it's unfortunate that you can't use a translucent nav bar and get the same effect.
