how to get the screen size until the bottom of the tabbar-CodePudding

I'm working on an custom tab bar button stuff and want to know how can I move up the button using the view's height or something programatically.

I have this plus button and I want to move up 10pt from the bottom.

let newButton = UIButton(frame: CGRect(x: 0, y: 0, width: 65, height: 65))
newButton.imageView?.contentMode = .scaleAspectFit
newButton.contentHorizontalAlignment = .fill
newButton.contentVerticalAlignment = .fill
      
var newButtonFrame = newEventButton.frame
newButtonFrame.origin.y = view.bounds.height - 65 - 10

So the code above works when an iPhone doesn't have a home button notch. Like get the height of the view and subtract button height and 10.

But, obviously, when there is a notch, it becomes something like the image below.

I want to move up the button from the bottom of the tabbar, so how can I get the height of the screen till the bottom of the tabbar, which works on both with/without home notch?

CodePudding user response：

For button origin use safe are insets, ıf device has notch safeAreaBottom will be like 44 , if not it will be 0:

let safeAreaBottom = UIApplication.shared.windows.first?.safeAreaInsets.bottom

Then use it :

newButtonFrame.origin.y = view.bounds.height - safeAreaBottom - 65 - 10
