IOS5 iPad popup controller delegate not sending messages to parent controller - ios

Question

I'm new to iOS programming and I can't get this simple concept to work -- I just want the popup controller to be able to call a method and send data on the parent controller. Can anyone spot what I'm doing wrong here?
in DetailViewController.h
#import <UIKit/UIKit.h>
#import "Employee.h"
#import "CompleteViewController.h"
#class EmployeesTVC;
#interface DetailViewController : UIViewController <UISplitViewControllerDelegate, UIPopoverControllerDelegate>
#property (strong) UIPopoverController *popController;
-(IBAction)completeButtonPressed:(id)sender;
#end
in DetailViewController.m (took out irrelevant parts)
#implementation DetailViewController {
__weak UIPopoverController *completePopover;
}
// ...
#pragma mark - Complete / Score popover methods
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NSLog(#"preparing for segue");
UIStoryboardPopoverSegue *popoverSegue = (UIStoryboardPopoverSegue *)segue;
UIPopoverController *scorePopoverController = [popoverSegue popoverController];
[scorePopoverController setDelegate:self];
self.popController = scorePopoverController;
}
- (IBAction)completeButtonPressed:(id)sender {
if (completePopover) {
[completePopover dismissPopoverAnimated:YES];
} else {
[self performSegueWithIdentifier:#"showScorePopover" sender:sender];
}
}
- (void) scoreAssigned:(NSString *)score {
NSLog(score);
NSLog(#"Score Assigned");
}
// ...
#end
CompleteViewController.h (the popup view controller)
#import <UIKit/UIKit.h>
#protocol CompleteViewDelegate <NSObject>
- (void)scoreAssigned:(NSString *)score;
#end
#interface CompleteViewController : UIViewController
#property (nonatomic, assign) id<CompleteViewDelegate> delegate;
- (IBAction)okButtonPressed:(id)sender;
#end
CompleteViewController.m
#import "CompleteViewController.h"
#implementation CompleteViewController
#synthesize delegate;
- (IBAction)okButtonPressed:(id)sender {
NSLog(#"OK Button Pressed");
[delegate scoreAssigned:#"100"];
}
#end

Answer 1

Is your first NSLog statement firing? "OK Button Pressed". If not, make sure (IBAction)okButtonPressed is wired up in Interface Builder. If so, but a break point on [delegate scoreAssigned:#"100"]; and hover over "delegate" with your mouse to see if it's nil, just to see if the delegate was successfully assigned. If this doesn't fix it, let us know exactly where you're getting to before things stop working.
Properly presenting a UIPopoverController
[completePopover setDelegate:self];
[completePopover presentPopoverFromBarButtonItem:yourButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
//or if you don't have a bar button item
[completePopover presentPopoverFromRect:CGRectMake(0.0, 0.0, 0.0, 0.0) inView:yourTargetView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Keep in mind that inView can be any subclass of UIView, like UIButton for instance.
