UIPopovercontroller in UISplitViewController

Question

My detailviewcontroller is called myDetailVC , with tableVC which is just a table on the side of myDetailVC.

in myDetailVC, I have a button that is supposed to show a popoverviewcontroller. However, it crashes when I press it.

in my .h file:

@property (strong, nonatomic) UIPopoverController *masterPopOverController;

and .m:

- (IBAction)goToPDF:(id)sender
{


        viewPDFViewController *MPPWV =[[viewPDFViewController alloc] initWithNibName:nil bundle:nil];

        self.masterPopOverController = [[UIPopoverController alloc] initWithContentViewController:MPPWV];

        [self.masterPopOverController presentPopoverFromRect:[sender frame] inView:[sender superview] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
        [self.masterPopOverController setPopoverContentSize:CGSizeMake(100, 100) animated:NO];


    }

Everything is connected fine in my xib, since I tested it by making it push to a viewcontroller instead of a popover. Can someone help me with this?

Answer 1

First, it looks like you're loading it up with a view controller that doesn't have anything in it:

viewPDFViewController *MPPWV =[[viewPDFViewController alloc] initWithNibName:nil bundle:nil];

Try specifying a Nib name, if you have one. It's possible that you don't have a NIB for that view controller. If that's the case you probably have a designated initializer -init method that you should be calling on it. Do that instead of calling -initWithNibName:

Second, it doesn't look like you're retaining the view controller you're loading into the pop over. It's possible that they require strong references. Try retaining it via property (or an ivar):

@property (nonatomic, strong) viewPDFViewController * MMPPWV;

Then when you access it do so via self:

self.MPPWV = [[viewPDFViewController alloc] initWithNibName:nil bundle:nil];
