iOS 10 iMessage app extension: how do i calculate the height of the extra tall navbar

I downloaded the Xcode 8 beta and was trying to play around with the iMessages app extension sdk but ran into an issue with their seemingly nonstandard nav bar height

when i transition into the app's expanded view, my image with the following frame CGRect(x: 0, y: 0, width: 100, height: 100) ends up partially hidden behind the nav bar. i would like it to appear below the nav bar.

i tried self.navigationController?.navigationBar.isTranslucent = false but it didn't work, which i guess makes sense since it's out of my app's scope to control.

has anyone played around with this yet? i want to avoid 2 things. simply guessing the appropriate height and moving away from a programmatic solution. compact expanded thanks for the help

Solution

  • It may help to have a constraint with the top layout guide like so:

    view.topAnchor.constraint(equalTo: self.topLayoutGuide.bottomAnchor).isActive = true
