As per the picture below, part of the TableView is appearing behind the Navigation Bar.
I had been ignoring it, thinking it was just the way the storyboard drew things because it looks ok in the app. But it can be problematic - sometimes, to select the cell behind the Navigation Bar, one needs to use the Document Outline.
Is that just how it goes? Or is there a way to get Xcode to draw things properly?
It looks like you have selected a translucent navigation bar which will not push down other subviews. Try using the standard or black navigation bar. It probably looks fine in the app because your navigation controller using the non-translucent bar.

is there an option to put a custom view in navigation bar? where the view can behave like contacts detail view, where on scrolling the header view gets squeezed or expanded. the back button looks handled natively, which is preferable. I could not see any option in UINavigationController API. am I missing something?
This is probably a custom view that blends in with the navigation bar (looks the same at the point they meet). No special nav bar api's needed. This question talks about how to remove the separator and make it look like the nav bar and underlying view blend together: Separator between navigation bar and view - iOS 7
I'm testing iPhone X behavior using the Xcode simulator. For some odd reason, if I'm hiding the Status Bar the Navigation Bar pushed upwards causing the title to completely disappear and cutting the left and right buttons. This is happening only on the iPhone X.

How can I hide the status bar and keep the Navigation Bar at a visible position?

One solution is to embed the navigation controller inside a container view controller which is properly constrained to the safe area.
Just create another view controller and drag a "Container View" from the Object Library. This view has top, bottom, leading, and trailing constraints to the safe area, all with constants equal to 0. If you control-drag from the container view to the navigation controller, you'll get an option to set an "embed segue" which will embed the selected view controller as a child view controller.
I set the status bar to be hidden on the new view controller I created, and it works fine.
This feels like something that UINavigationBar should handle automatically, but this workaround seems like it should work pretty well.
Another note: if you change the color of the navigation bar, you'll also need to create another view above the container view, and change its color to match the color of the navigation bar.
I, for a small app, changed from using a Push to a Modal segue and adding in my own navigation bar. I used Push because it looks good, and already had a Modal for another part, which I wanted to animate differently for style reasons.
For smaller apps this may be the quickest and easiest solution, but my next update I need to use the navigation controller. For that I think I'll switch on the status bar, which is no big deal for me and allows it to work.
I think you need to use "safeAreaLayoutGuide" new update in iOS 11
Apple has provided us with the necessary APIs to get around the unsafe regions of this iphone x. We do this by using the new safeAreaLayoutGuide anchors in our code

I have an rss app that I'm working on in xcode and the articles load up in a full screen web view. I need to place a "share" button in the navigation bar but since my uiwebview is full screen it won't show up when I run the app. I even tried cropping the top of the web view lower and placing the button there but still no luck. Here is an example of what I mean:
The share button needs to be on the right side of the navigation bar but i cannot seem to figure out how that make that work.
Thanks in advance
Fist of all, your top navigation bar seems to be missing (judging by your image). Since the nav bar is missing there is no possible way that the share button will be visible. You can do this is the IB or in your code.
For your IB you can move the view controller's 'layer's' so to speak. When you place all the elements down, your VC should look something like this:
On the left hand side we can see what subviews are at the top and which ones are at the bottom.
As we can see here that the UIWebView is at the top of the list, so it'll be at the bottom of the pile. The navigation bars are further down the list so they'll be at the top of the pile. So due to this they'll go over the UIWebView.
The other way to do this is using insertSubview:aboveSubview:. Fist of all you'll add your UIWebView using addSubview: and then add the nav bar using insertSubview:aboveSubview: and finally you'll add your button the someway as you did for the nav bar, but this time you'll be adding the button above the nav bar not the web view.
My best guess is that your forgetting to add another navigation bar to the top of the screen. Hope this helps!!
I am having an issue with the translucent UINavigationBar and UITabBar in iOS 7, whereby if I only have the UINavigationBar translucent it works as I would expect it to, however as soon as set the UITabBar to translucent I get a strange effect happening in one out the four tabs in the app. Let my explain with some images:
This image shows the interface where only the nav bar is set to translucent:
With this image showing the result of the user scrolling the content up and under the nav bar:
Now, this is how I would expect it to look, and when the user scrolls the content back from under the nav bar it looks as it did before. However if I also set the UINavigationBar to translucent, and scroll the content to under the nav bar, the result is different to the second image:
Event the tab bar doesn't look right to me. This next image shows that the look of the nav bar if now different to what it was before, when the content is scrolled back from underneath it:
Again, I also don't thing that the look of the tab bar is correct, as the next image shows a different tab with content underneath it, with only a subtle change to the look of the tab bar:
Has anyone else had similar issues to this? (This is all set up in a storyboard)
Well, this was an annoying one. I added a fifth tab which had a MKMapView in it. On running the app and selecting the fifth tab, the tint colour from the nav and tab bars was removed, so I did a search and came across MKMapView affecting UINavigationBar and UITabBar
The test device I was using had iOS 7.0.2 on it, which falls in line with the bug mentioned; so have therefore updated it to the 7.1, and low and behold everything looks as it should.
I have a view controller with a navigation item. The view inside the navigation item rotates, but the navigation bar at top does not. I don't understand why only part of the application is rotating.
There's seems to be pretty much about this in google.
This one looks promising
