Popup View Controller Camera

[VIKRANTKRISHNA]

I updated my app to run on iOS 8 sdk, and looks like camera and photos attachment stopped working. Action sheet shows up when tapping add attachment, but nothing happens when tapping take picture or pick from photo library. It's giving a warning "Warning: Attempt to present <UIImagePickerController: 0x171c8200>  on <AGSAttachmentCollectorViewController: 0x1ac979a0> which is already presenting <UIAlertController: 0x1abbfda0>"

I'm also having this problem.  Have you found a work around?

[DiveshGoyal]

Can you try setting the modalPresenter property (10.2.4: AGSPopupsContainerViewController Class Reference ) to the app's view controller that is displaying the popups vc? You might need to tweak your app's vc hierarchy a little to make it work correctly on iOS 8 because of some changes to how alert views are displayed.

I have the same issue.

Does anyone has a solution yet?

This issue is being looked into - I'll post an update soon.

Thanks,

I have the same problem and created a ticket to ESRI tech support but no solution yet.

"Warning: Attempt to present <UIImagePickerController: 0x1302c7000> on <AGSAttachmentCollectorViewController: 0x1335051b0> which is already presenting <UIAlertController: 0x12f69f340>"

You can use the sample project from https://github.com/Esri/arcgis-runtime-samples-ios

The project name is "OfflineFeatureEditingSample"

To add attachment function works in simulator but not in iPad Air 8.1 device.  Thanks!

All,

Here's a workaround

By implementing popupsContainer:wantsToShowViewController:ofType:fromViewController:atRect: method of AGSPopupsContainerDelegate, you can present popupsContainer's different view controllers. Check if the view about to be presented in UIImagePicker, and delay the presentation. This ensures the UIAlertController that displays the action sheet in iOS8 is dismissed before the image picker is displayed.

The actual issue will be fixed in the next release of the SDK.

- (void) popupsContainer: (id< AGSPopupsContainer >) popupsContainer

wantsToShowViewController: (AGSViewController *) svc

    ofType: (AGSPopupViewType) viewType

    fromViewController: (AGSViewController *) fvc

    atRect: (CGRect) rect {

  svc.modalPresentationStyle = UIModalPresentationFormSheet; //Your preferred presentation style

  if (viewType == AGSPopupViewTypeUIImagePicker) {

  //Delay runloop so UIAlertController is dismissed before image picker is presented.

  [[NSOperationQueue mainQueue] addOperationWithBlock:^{

       [fvc presentViewController:svc animated:YES completion:^{

        NSLog(@"Presenting Image Picker");

       }];

      }];

  }

  else {

  //This is necessary as you will have to present all other view controllers too.

  [fvc presentViewController:svc animated:YES completion:^{

  }];

  }

}

//You will have to implement this method to dismiss the view controllers.

- (void) popupsContainer: (id< AGSPopupsContainer >) popupsContainer

wantsToHideViewController: (AGSViewController *) vc

    ofType: (AGSPopupViewType) viewType {

  [vc dismissViewControllerAnimated:YES completion:^{

  }];

}

Thanks,

Suganya

Hi

Do you have a swift solution for the above problem?

Thanks.

When using the patch codes from above to take photo attachment, if we take only one photo then maybe less percentage to crash. When taking more than two then high percentage to crash the whole app. Thanks!

[[NSOperationQueue mainQueue] addOperationWithBlock:^{

       [fvc presentViewController:svc animated:YES completion:^{

        NSLog(@"Presenting Image Picker");

       }];

      }];

  }

I record some log messages for your reference. Hopefully this can be fixed.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
