IOS App Crash After Scanning #120

Open LeonWill95 opened 1 year ago

LeonWill95 commented 1 year ago

This project works brilliantly in Android, we are having a problem in iOS, if you open the form, close it, its fine, if you click outside the scanner to close the form its works fine, if you open the form and then scan a QR it crashes the code after the result has been saved and the form closes which in turn crashes the app completely.

Is there any barcode scanner that works in iOS and Maui Blazor / Maui?

iPhone Xr iOS 16.31
Model Number MRY42B/A

xCode 14.2 Microsoft Visual Studio Version 17.5.3 .net 7

Use methods Device.BeginInvokeOnMainThread(()

private void scanner_BarcodesDetected(object sender, ZXing.Net.Maui.BarcodeDetectionEventArgs e) { try { Device.BeginInvokeOnMainThread(() => { scanner.IsDetecting = false; SecureStorage.Default.SetAsync("Camera", Switch.IsToggled.ToString()); this.Close(e.Results[0].Value); });

    }
    catch
    {

    }

}

Getting the same on iOS 16.4, iPhone Pro 14. Wrapped in Device.BeginInvokeOnMainThread(() as suggested above. Just launching causes crash with no methods called for detection. Thanks
