Delegate method not executing - ios

Question

I'm really having a tough time figuring out why one of my delegate methods performs perfectly, but another won't. Here is the relevant code for the delegate that isn't working:
SideBarController.h
#import <UIKit/UIKit.h>
#import "Report.h"
#protocol ReportSelectViewControllerDelegate <NSObject>
#optional
- (void) viewSelectMonitoredArea:(Report *)report;
#end
#interface SidebarController : UIViewController <UITableViewDataSource, UITableViewDelegate>
#property (nonatomic, weak) id <ReportSelectViewControllerDelegate> delegate;
#property (nonatomic, weak) IBOutlet UITableView *tableView;
#property (nonatomic, weak) Report *selectedReport;
#end
SideBarController.m
#import "SidebarController.h"
#interface SidebarController ()
#end
#implementation SidebarController
#synthesize tableView = _tableView;
#synthesize delegate;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSMutableArray *sectionArray = [self.tableViewItems objectAtIndex:indexPath.section];
NSDictionary* item = sectionArray[indexPath.row];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:item[#"title"] forKey:#"CurrentReportTitle"];
self.selectedReport = [Report where:#{#"reportTitle": item[#"title"]}].lastObject;
[self.delegate viewSelectMonitoredArea:self.selectedReport];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
DetailReportViewController.h
#import <UIKit/UIKit.h>
#import "BDBSplitViewController.h"
#import "SidebarController.h"
#interface DetailReportViewController : BDBDetailViewController <UISplitViewControllerDelegate, ReportSelectViewControllerDelegate >
#end
DetailReportViewController.m
#import "DetailReportViewController.h"
#interface DetailReportViewController ()
#end
#implementation DetailReportViewController
- (void)viewDidLoad
{
[super viewDidLoad];
SidebarController *sideBarController = [[SidebarController alloc] init];
sideBarController.delegate = self;
}
- (void) viewSelectMonitoredArea:(Report *)report {
NSLog(#"viewSelectMonitoredArea was called");
}
Another delegate written exactly the same way from another controller to the DetailReportViewController works just fine. When I put a breakpoint right after the delegate is called, I notice that the delegate has a nil value. Any help would be greatly appreciated.
EDIT:
Sorry, I forgot to put in sideBarController.delegate = self in the DetailReportViewController.h example. It is in the original code.

Answer 1

The DetailReportViewController class needs to get a reference to the "SideBarController" instance and then set itself as the delegate. In DetailReportViewController:
// This needs to be in the DetailReportViewController class
// Assume we have a reference to the SideBarController in the DetailReportViewController class called sideBarControllerInstance
sideBarControllerInstance.delegate = self;

Answer 2

The solution spurred on by Michael Dautermann was to put
DetailReportViewController *detailReport = [[DetailReportViewController alloc] init];
self.delegate = detailReport;
right before
[self.delegate createSelectMonitoredArea:self.selectedReport];
Thanks!
