I have about 40 ipad minis of various ages running an app I developed managed on an mdm. We are upgrading devices so I recently bought 4 ipad mini v6 in December. Everything appears to work except printing. Printing does work via Notes so I think its something with xcode. The user can swipe on a component to print a barcode to a Brother barcode printer. Again, I can print to this computer using Notes. On any of the other 38 older ipad minis, a AirDrop dialog appears like this.
. but on the new devices it doesn’t work and looks like this
see the empty bar at the top of the screen. Here is the relevant code. I think it must have something to do with UIActivityViewController. This code works fine on the older devices but not on the newest ones.
let renderer = UIGraphicsImageRenderer(size: CGSize(width: 1000, height: 400))
let BarcodeImg = renderer.image { ctx in
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center
let attrs: [NSAttributedString.Key: Any] = [
.font: UIFont.systemFont(ofSize: 65),
.paragraphStyle: paragraphStyle
]
let myQRCode = generateBarcode(from: self.qrCodeLabel.text!)
myQRCode?.draw(at: CGPoint(x: 15, y: 60))
let string = self.qrCodeLabel.text!
let attributedString = NSAttributedString(string: string, attributes: attrs)
attributedString.draw(with: CGRect(x: 10, y: 10, width: 1000, height: 400), options: .usesLineFragmentOrigin, context: nil)
}
qrCodeImage.image = BarcodeImg
let screenSize: CGRect = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
let vc = UIActivityViewController(activityItems: [BarcodeImg], applicationActivities: [])
let popover = vc.popoverPresentationController
popover?.sourceView = view
popover?.sourceRect = CGRect(x: 32, y: 32, width: screenWidth, height: screenHeight)
present(vc, animated: true)
Please let me know if you have any ideas what is causing this or how to troubleshoot the issue.
