Navigation bar title view missing in iOS11

Question

I'm working on a project in swift for iPad. Have placed an image view in Navigation bar title view from story board. The title view is displaying as expected in iOS 10 and below. The same project when i run in iOS 11 simulators and the physical devices Navigation bar is not showing the title view, any leads would be appreciated.

Create a custom view and override below method in the custom title view class to update view frame size at runtime.

Obj-C

-(CGSize)intrinsicContentSize
{
    [super intrinsicContentSize];
    return UILayoutFittingExpandedSize;
}

Swift

override var intrinsicContentSize: CGSize {
    return UILayoutFittingExpandedSize
}

Check and let me know is it working for you or not ?

Just debug with hierarchy view option and you come to know frame size of custom titleView is zero in ios 11 alone. To update frame size at runtime you need to call this method. – Chandrapandian J Oct 23 '17 at 10:29
Oh is it? does this code shows any impact on the existing behavior for iOS 10 and below? or it's specific to iOS 11 only? – Naresh Reddy M Oct 23 '17 at 10:31
I hope, No impact on existing behavior of iOS 10 and below. Please check and let me know. – Chandrapandian J Oct 23 '17 at 10:35

Maybe this can help you

let widthConstraint = view.widthAnchor.constraint(equalToConstant: width)
let heightConstraint = view.heightAnchor.constraint(equalToConstant:height)
widthConstraint.isActive = true
heightConstraint.isActive = true

view is the view that you use as a custom title view. And width and height is the size that you want to use. You can use:

let width = view.frame.width
let height = view.frame.height
