Question

I know there are a few questions on stack already regarding this, and I have been through them all.

When I debug, a line of code that calls a delegate method appears to be ignored. here’s the line:
[_delegate insertDataLocation:dbLocation Time:dbTime Reminder:dbReminder];

I am assuming it’s a matter of the delegate not being set properly, so here’s how I’ve set it:

ViewController.h

@protocol mapDelegate;

@interface ViewController : UIViewController

@property (strong, nonatomic) id<mapDelegate> delegate;

ViewController.m

@synthesize delegate = _delegate;

- (void)viewDidLoad
{
[super viewDidLoad];
[self setDelegate:_delegate];
}

//Here's where I call the method, FYI
[_delegate insertDataLocation:dbLocation Time:dbTime Reminder:dbReminder];

AppDelegate.h

@protocol mapDelegate
-(void)insertDataLocation:(NSString*)l Time:(NSString*)t Reminder:(NSString*)r;
@end

@interface AppDelegate : UIResponder <UIApplicationDelegate, mapDelegate>

AppDelegate.m

-(void)insertDataLocation:(NSString*)l Time:(NSString*)t Reminder:(NSString*)r {
//Here's my method's code
}

Answer 1

1) Get rid of the id<mapDelegate> delegate; declaration at the start of your .h file. You’ve tied your property to a variable called _delegate in your @synthesize statement, so the other one is misleading.

2) You say, “here’s how i’ve set it,” but I don’t see anything that actually sets the delegate to be some object.

3) Using self.delegate rather than _delegate inside normal methods is usually a better idea.
