I want to add an UIMenu to my application, I was practicing with it and now have the question if is possible to set the location of the UIMenu
a little higher than the button is currently displaying it:
as you can see in this photo the menu currently overlay the tab bar and I wanted to set it a little higher than than the tab bar. here is my code:
let menu = UIMenu(title: "", children: [
UIAction(title: NSLocalizedString("Gallery", comment: ""), image: UIImage(systemName: "folder"), handler: {
(_) in
self.loadPhotoGallery()
})
])
btnMenuExtras.menu = menu
iOS 14+
Sinse iOS 14 UIControl
has method that provides point to which attach a menu
/// Return a point in this control's coordinate space to which to attach the given configuration's menu.
@available(iOS 14.0, *)
open func menuAttachmentPoint(for configuration: UIContextMenuConfiguration) -> CGPoint
so you can override UIButton
to provide desired location for a menu (calculated or hardcoded) relatively to the button itself (`cause it is in button's coordinate space) and use that button either in storyboard (as a class for control) or created programmatically (if you need to inject it somewhere):
class MyButton: UIButton {
var offset = CGPoint.zero
override func menuAttachmentPoint(for configuration: UIContextMenuConfiguration) -> CGPoint {
// hardcoded variant
// return CGPoint(x: 0, y: -50)
// or relative to orginal
let original = super.menuAttachmentPoint(for: configuration)
return CGPoint(x: original.x + offset.x, y: original.y + offset.y)
}
}
class ViewController: UIViewController {
@IBOutlet weak var btnMenuExtras: MyButton! // << from storyboard
override func viewDidLoad() {
super.viewDidLoad()
let menu = UIMenu(title: "", children: [
UIAction(title: NSLocalizedString("Gallery", comment: ""), image: UIImage(systemName: "folder"), handler: {
(_) in
// self.loadPhotoGallery()
})
])
// offset is hardcoded for demo simplicity
btnMenuExtras.offset = CGPoint(x: 0, y: -50) // << here !!
btnMenuExtras.menu = menu
}
}
Result:
Demo prepared & tested with Xcode 13 / iOS 15
