UIActivityViewController在iOS 9.1中不起作用

Question

NSString *sharedMsg = sharecontent;
NSArray *sharedObjects = [NSArray arrayWithObjects:sharedMsg, nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:sharedObjects applicationActivities:nil];
activityViewController.popoverPresentationController.sourceView = self.view;
[self presentViewController:activityViewController animated:YES completion:nil];
