Ios – UIActionSheet from Popover with iOS8 GM

iosios8uiactionsheetuialertcontrolleruipopovercontroller

Anyone is getting this message while trying to show UIActionSheet from popover?

Your application has presented a UIAlertController () of style UIAlertControllerStyleActionSheet. The modalPresentationStyle of a UIAlertController with this style is UIModalPresentationPopover. You must provide location information for this popover through the alert controller's popoverPresentationController. You must provide either a sourceView and sourceRect or a barButtonItem. If this information is not known when you present the alert controller, you may provide it in the UIPopoverPresentationControllerDelegate method -prepareForPopoverPresentation.

Previously to the GM I used some workaround for converting the UIActionSheet to UIAlertController and this is working fine.
However it seems that Apple tried to solve the UIActionSheet issues and I didn't want to use my workaround – but it seems that I have no choice…

To support iPad, include this code:

alertView.popoverPresentationController?.sourceView = self.view
alertView.popoverPresentationController?.sourceRect = self.view.bounds
// this is the center of the screen currently but it can be any point in the view

self.presentViewController(alertView, animated: true, completion: nil)

The error message is telling you that you need to give the alert controller's popoverPresentationController a location so that it can position itself properly. This is easy to do -- just check to see if there's a popover controller and add the sender as the source.

If your button is a UIBarButtonItem:

if let popoverController = alertController.popoverPresentationController {
    popoverController.barButtonItem = sender
}
self.presentViewController(alertController, animated: true, completion: nil)

Otherwise:

if let popoverController = alertController.popoverPresentationController {
    popoverController.sourceView = sender
    popoverController.sourceRect = sender.bounds
}
self.presentViewController(alertController, animated: true, completion: nil)

Java – Weblogic 10.3.1 gives ‘Dependency injection failure’ warning when publishing code

There may be a couple of issues at work here. I'm getting a very similar error in just a straight servlet that is trying to load an ejb that isn't packaged in the same ear, I'm still trying to track that down. I also know that there is a difficulty when loading EJB v2.x that is supposed to be fixed in Weblogic 10.3.3. If you find anything please let me know, and I'll do the same. One thing I have noticed is that if I load the EJB via initialContext.lookup, it works fine.

YMMV
