Using UIAlertController you can access the popoverPresentationController property to set the sourceView (aka inView) and sourceRect (aka fromRect). This gives the same appearance as the previous showFromRect:inView:

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title" message:@"message" preferredStyle:UIAlertControllerStyleActionSheet];

// Set the sourceView.
alert.popoverPresentationController.sourceView = self.mySubView;

// Set the sourceRect.
alert.popoverPresentationController.sourceRect = CGRectMake(50, 50, 10, 10);

// Create and add an Action.
UIAlertAction *anAction = [UIAlertAction actionWithTitle:@"Action Title" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
NSLog(@"Action Pressed");
}];

[alert addAction:anAction];

// Show the Alert.
[self presentViewController:alert animated:YES completion:nil];
