ActionSheet not working iPad
IosIpadSwiftUiactionsheetIos Problem Overview
I'm using ActionSheet in my application. On my iPhone it works, but it doesn't on the iPad simulator.
this is my code:
@IBAction func dialog(sender: AnyObject) {
let optionMenu = UIAlertController(title: nil, message: "Choose Option", preferredStyle: .ActionSheet)
let deleteAction = UIAlertAction(title: "Delete", style: .Default, handler: {
(alert: UIAlertAction!) -> Void in
println("Filtre Deleted")
})
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: {
(alert: UIAlertAction!) -> Void in
println("Cancelled")
})
optionMenu.addAction(deleteAction)
optionMenu.addAction(cancelAction)
self.presentViewController(optionMenu, animated: true, completion: nil)
}
And my error:
> Terminating app due to uncaught exception 'NSGenericException',
> reason: 'Your application has presented a UIAlertController
> (

You need to provide a source view or button just before presenting optionMenu since on iPad its a UIPopoverPresentationController, As it says in your error. This just means that your action sheet points to the button letting the user know where it started from.
For example if you're presenting your optionMenu by tapping on the right navigation bar item. You could do something like this:
optionMenu.popoverPresentationController?.barButtonItem = self.navigationItem.rightBarButtonItem
self.presentViewController(optionMenu, animated: true, completion: nil)
or you could set a view like this:(You just need one of these 2)
optionMenu.popoverPresentationController?.sourceView = yourView
self.presentViewController(optionMenu, animated: true, completion: nil)
Also keep in mind that if you change your UIAlertControllerStyle to Alert instead of action sheet, You wouldn't need to specify this. I am sure you must have figured it out but i just wanted to help anyone who comes across this page.

Same problem for me. I had a UIAlertController that worked fine on phone, but crashed on iPad. The sheet pops up when a cell is tapped from a table view.
For Swift 3, I added 3 lines of code right before presenting it:
...
sheet.popoverPresentationController?.sourceView = self.view
sheet.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection()
sheet.popoverPresentationController?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
self.present(sheet, animated: true, completion: nil)

Swift 3
As said before, you should configure UIAlertController to be presented on a specific point on iPAD.
Example for navigation bar:
// 1
let optionMenu = UIAlertController(title: nil, message: "Choose an option", preferredStyle: .actionSheet)
// 2
let deleteAction = UIAlertAction(title: "Option 1", style: .default, handler: {
(alert: UIAlertAction!) -> Void in
print("option 1 pressed")
})
let saveAction = UIAlertAction(title: "Option 2", style: .default, handler: {
(alert: UIAlertAction!) -> Void in
print("option 2 pressed")
})
//
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: {
(alert: UIAlertAction!) -> Void in
print("Cancelled")
})
// 4
optionMenu.addAction(deleteAction)
optionMenu.addAction(saveAction)
optionMenu.addAction(cancelAction)
// 5
optionMenu.popoverPresentationController?.barButtonItem = self.navigationItem.rightBarButtonItem
self.present(optionMenu, animated: true) {
print("option menu presented")
}
Solution 4 - Ios
If you wish to present it in the centre with no arrows [Swift 3+]:
if let popoverController = optionMenu.popoverPresentationController {
popoverController.sourceView = self.view
popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController.permittedArrowDirections = []
}
self.present(optionMenu, animated: true, completion: nil)
Solution 5 - Ios
add statements in the following terms before presented.
optionMenu.popoverPresentationController.sourceView = self.view;
optionMenu.popoverPresentationController.sourceRect =
CGRectMake(0,0,1.0,1.0);
@IBAction func dialog(sender: AnyObject) {
...
optionMenu.popoverPresentationController.sourceView = self.view;
optionMenu.popoverPresentationController.sourceRect = CGRectMake(0,0,1.0,1.0);
self.presentViewController(optionMenu, animated: true, completion: nil)
}
it will work well.

Just a note that you can also get this error if you haven't linked the sourceview in IB to the relevant variable in your app.
Solution 7 - Ios
you need to add this for Ipad
alertControler.popoverPresentationController?.sourceView = self.view
popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)

I've done this package to manage ActionSheet and Popover in iPhone, Ipad and Mac. https://github.com/AndreaMiotto/ActionOver
