I want to make a navigation bar that changes height in it's detail view just like the messages app in iOS 10. How can I do that?
Edit:
I am looking to change the height dynamically. SizeThatFits() Permanently changes the height.
If you are trying to do something else that requires the navigation bar to be resized, that's not supported. iOS 11 and Above

How does the iOS app customize the height of the navigation? For example, the current system navigation height 44, want to change to 100. thanks
Xcode 11.1, iOS 13.1
it is possible but its not something what apple will approve when you send the app to the store rather than changing the height of the navigation bar you could make the bar view transparent and add a UIView which has the content.
Setting a custom navigation height won't pass the review process on the App Store. If you want a large NavigationBar you could always set the Bar to large titles:
navigationController?.navigationBar.prefersLargeTitles = true
Apple docs for large titles
I have a custom navigation bar that worked well until iOS 11. It appears smaller than it should and seems to ignore the status bar height or something.
I set the whole thing programmatically and the height is set to 64.
have you tried to disable (untick) safe area?
I have a UIViewController subclass which when I run the app on iOS 7, the status bar shows on top of my view. Is there a way to avoid this? I do not want the status bar to be hidden. Is there a way to show the status bar above my app. I present my view using presentViewController. Please guide what I am missing?
In Xcode, In storyboard there is an option of iOS6/7 delta. set delta Y to 20 pixel of your view, to make compatible with iOS7.For this you have to disable auto layout, you can use auto resizing.
This is quite common issue. Starting from iOS 7 Status Bar is a part of the controller's view. Apple even have added special attribute of UIView in the Interface Builder: iOS 6/7 Deltas. To fix your problem and make your view look the same in different iOS versions, go to Size inspector and set Delta Y to 20.0.
I've got a background for the project that I am working on, which includes a 20px coloured bar for the top of an iOS 7 device.
This worked fine without autolayout, setting a 20px delta in storyboard. But now I can't do that, and I am stuck with constraints - which I cannot set on a per-OS basis.
Whatever I do, I seem to end up with the version on iOS 7 being 20px higher than on ios 6... Something I need to rectify, as I also have a bar under that status bar which is coloured for a navigation controller.
I've attached the background image - if I need to modify it to work with autolayout, I'm happy to do that.
There is a "top layout guide" object in your view hierarchy. If you build vertical constraints based on that, they pin to the top of the window if there is no status bar, or under the status bar otherwise. Use that.
I developed a simple app for iOS6 and now I'm to updating its appearence for iOS7. One of the first changes I would like to do concerns the navigation bar.
I'm using the standard navigation bar UI component that comes with xcode. While in iOS6 the navigation bar was clearly placed under the status bar (i.e. battery, carrier and hour), in iOS7 the navigation bar blends with the status bar.
My question is: how can I increase the height of the navigation bar and place the title vertically a little lower than the default position?
Currently I have this:
And the title is too close to the time. I would like to achieve this (standard Photos app that comes with iOS7):
here the title of the bar is lower and the bar is larger (or is just shifted down).
It have been trying to modify the height of the navigation bar through the size inspector but with no success.
It's probaly a very easy issue to solve, however I'm still new to xcode development and I can't figure it out.
Stick the view controller in a Navigation Controller, that should immediately solve the problem
