Set height for popover in landscape mode - ios

Question

I want to modify the height of popover in landscape mode, but it only work in portrait mode.
I want it's height equal to screenSize.height * 0.7, but it doesn't work with my code below.
Here is my code:
if let orientation = UIDevice.current.value(forKey: "orientation") as? Int {
let diamondViewController = DiamondViewController()
diamondViewController.mode = .buyDiamondPopup
diamondViewController.resetBackgroundColor = {
self.view.backgroundColor = .clear
}
let screenSize = UIScreen.main.bounds
if orientation == 3 { // LandscapeRight
diamondViewController.preferredContentSize = CGSize(width: screenSize.width * 0.6, height:
screenSize.height * 0.7)
} else {
diamondViewController.preferredContentSize = CGSize(width: screenSize.width - 60, height:
min(screenSize.height - 180, CGFloat(5 * 70 + 110) ))
}
diamondViewController.modalPresentationStyle = .popover
if let popover = diamondViewController.popoverPresentationController {
popover.permittedArrowDirections = .init(rawValue: 0)
popover.sourceView = self.view
popover.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popover.delegate = self
self.view.backgroundColor = UIColor.black.withAlphaComponent(0.5)
self.present(diamondViewController, animated: true, completion: nil)
}
}
...
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return .none
}

Answer 1

Instead of this
diamondViewController.preferredContentSize = CGSize(width: screenSize.width * 0.6, height: screenSize.height * 0.7)
Try this below
diamondViewController.view = CGRect(x: diamondViewController.view.frame.origin.x ,y: diamondViewController.view.frame.origin.y ,width: screenSize.width * 0.6, height: screenSize.height * 0.7)
If it doesn't help then let me know.

Have you tried using the "Vary for traits" tool? It allows you to apply different constraints depending on the devices orientation. It can be found near the bottom right corner in storyboard next to the different constraint options.

I think you have to set landscape's height in a dispatched thread. Here is my suggestion.
if let orientation = UIDevice.current.value(forKey: "orientation") as? Int {
let diamondViewController = DiamondViewController()
diamondViewController.mode = .buyDiamondPopup
diamondViewController.resetBackgroundColor = {
self.view.backgroundColor = .clear
}
// HERE IS THE CHANGE: CALL FUNC TO GET SIZE
let size = diamondViewController.myPreferedContentSize(landscape: landscape)
diamondViewController.preferredContentSize = size
...
}
}
The func myPreferedContentSize is defined in 'diamondViewController' class as following:
func myPreferedConentSize(landcape: Bool) -> CGSize
{
let screenSize = UIScreen.main.bounds
let retSize: CGSize
if landscape { // LandscapeRight
retSize = CGSize(width: screenSize.width * 0.6, height:
screenSize.height * 0.7)
} else {
retSize = CGSize(width: screenSize.width - 60, height:
min(screenSize.height - 180, CGFloat(5 * 70 + 110) ))
}
return retSize
}
In your diamondViewController class, override this func and add codes:
override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
super.viewWillTransition(to: size, with: coordinator)
let landscape = size.width > size.height
DispatchQueue.main.async {
[weak self] in
guard let this = self else { return }
this.preferredContentSize = this.myPreferedConentSize(
landscape: landscape)
}
}
It is important to call func myPreferedConentSize in DispatchQueue.main.async thread. In this async main thread, it will ask your view controller to set preferred content size in either portrait or landscape orientation correctly.
