UIActivityViewController crashing on iOS 8 iPads
On iPad the activity view controller will be displayed as a popover using the new UIPopoverPresentationController, it requires that you specify an anchor point for the presentation of the popover using one of the three following properties:
- barButtonItem
- sourceView
- sourceRect
In order to specify the anchor point you will need to obtain a reference to the UIActivityController's UIPopoverPresentationController and set one of the properties as follows:
if ( [activityViewController respondsToSelector:@selector(popoverPresentationController)] ) {
// iOS8
activityViewController.popoverPresentationController.sourceView =
parentView;
}
Same problem is come to my project then i found the solution that to open the UIActivityViewController
in iPad we have to use UIPopoverController
Here is a code to use it in iPhone and iPad both:
//to attach the image and text with sharing
UIImage *image=[UIImage imageNamed:@"giraffe.png"];
NSString *str=@"Image form My app";
NSArray *postItems=@[str,image];
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:postItems applicationActivities:nil];
//if iPhone
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
[self presentViewController:controller animated:YES completion:nil];
}
//if iPad
else {
// Change Rect to position Popover
UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:controller];
[popup presentPopoverFromRect:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/4, 0, 0)inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
For swift 4.2 / swift 5
func openShareDilog() {
let text = "share text will goes here"
// set up activity view controller
let textToShare = [text]
let activityViewController = UIActivityViewController(activityItems: textToShare, applicationActivities: nil)
activityViewController.excludedActivityTypes = [.airDrop]
if let popoverController = activityViewController.popoverPresentationController {
popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
popoverController.sourceView = self.view
popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
}
self.present(activityViewController, animated: true, completion: nil)
}
