Since I don't use storyboards to create my views, I was wondering if there's the "Use Safe Area Guides" option programmatically or something like that.
I've tried to anchor my views to
view.safeAreaLayoutGuide
but they keep overlapping the top notch in the iPhone X simulator.
Here is sample code (Ref from: Safe Area Layout Guide):
If you create your constraints in code use the safeAreaLayoutGuide property of UIView to get the relevant layout anchors. Let’s recreate the above Interface Builder example in code to see how it looks:
Assuming we have the green view as a property in our view controller:
private let greenView = UIView()
We might have a function to set up the views and constraints called from viewDidLoad:
private func setupView() {
greenView.translatesAutoresizingMaskIntoConstraints = false
greenView.backgroundColor = .green
view.addSubview(greenView)
}
Create the leading and trailing margin constraints as always using the layoutMarginsGuide of the root view:
let margins = view.layoutMarginsGuide
NSLayoutConstraint.activate([
greenView.leadingAnchor.constraint(equalTo: margins.leadingAnchor),
greenView.trailingAnchor.constraint(equalTo: margins.trailingAnchor)
])
Now, unless you are targeting iOS 11 and later, you will need to wrap the safe area layout guide constraints with #available and fall back to top and bottom layout guides for earlier iOS versions:
if #available(iOS 11, *) {
let guide = view.safeAreaLayoutGuide
NSLayoutConstraint.activate([
greenView.topAnchor.constraintEqualToSystemSpacingBelow(guide.topAnchor, multiplier: 1.0),
guide.bottomAnchor.constraintEqualToSystemSpacingBelow(greenView.bottomAnchor, multiplier: 1.0)
])
} else {
let standardSpacing: CGFloat = 8.0
NSLayoutConstraint.activate([
greenView.topAnchor.constraint(equalTo: topLayoutGuide.bottomAnchor, constant: standardSpacing),
bottomLayoutGuide.topAnchor.constraint(equalTo: greenView.bottomAnchor, constant: standardSpacing)
])
}
Result:
