I'm trying to implement the new UIPopoverPresentationController
in my iPhone app (using Objective C). What I want is a simple popover with a tableview that emanates from the initiating button.
–Edit–
Here's my REVISED code, adapted from research in the docs, SO, and from input in comments below:
- (IBAction)selectCategoryBtn:(UIButton *)sender
{
[self performSegueWithIdentifier:@"CatSelectSegue" sender:self.selCatButton];
}
-(void) prepareForSegue:(UIStoryboardSegue *) segue Sender:(id) sender
{
if (sender == self.selCatButton)
{
if ([segue.identifier isEqualToString:@"CatSelectSegue"])
{
UIPopoverPresentationController *controller = segue.destinationViewController;
controller.delegate = self;
controller.sourceView = self.selCatButton;
controller.sourceRect = self.selCatButton.frame;
}
}
}
-(UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller
{
return UIModalPresentationNone;
Here's my storyboard hookup:
However this simply presents a tableview in a modal fashion, rising up from the bottom and consuming the entire screen.
I've googled, and looked all over SO, but it appears that I'm not the only one confused by what I'd hoped would resolve a nettlesome issue for the iPhone.
Can anyone see a glitch in my code or direct me to a clear tutorial? I've looked, but maybe the API is just so new nobody's got a handle on it yet.
Thanks!
2nd edit:
Here's what gets presented as a result of the code above. I reduced the size of the tableview in the View Controller I expected to be presented as a popover. I colored the background gray, just to clarify what's showing up instead of the popover.

Steps:
A) Link your
UIButton
to the popover's view controller using thePresent As Popover
segue type. I actually had to create a new project to get this to appear but it's probably something to do with the base SDK.B) Make the View Controller containing the
UIButton
conform to the<UIPopoverPresentationControllerDelegate>
. E.g. In yourMyViewController.m
file add:C) Add the method below to the View Controller containing the
UIButton
:D) Add the following into your
prepareForSegue:sender:
replacing yoursegue.identifier

Edit: My test app TPOPViewController.m file where the magic happens:
