Question

I am having an issue with the addObject method of an NSMutableArrayObject. Here’s the code I’m using right now:

- (void)addBirdSightingWithName:(NSString *)name location:(NSString *)location {
    BirdSighting *bird;
    NSDate *today = [NSDate date];
    bird = [[BirdSighting alloc] initWithName:name location:location date:today];
    [self.masterBirdSightingList addObject:bird];
    NSLog(@"Elements: %d", [self.masterBirdSightingList count]);
}

When this code runs, the NSLog call prints the value 0 to the console. I don’t know what could be causing this.

EDIT:

I have looked deeper into the code, and I have discovered that the problem is that my BirdSightingDataController is never initialized. Now my question is: Where can I place the init for my BirdSightingDataController? In the viewDidLoad?

Thanks to everyone for the help.

Answer 1

Did you allocate memory to masterBirdSightingList?

self.masterBirdSightingList = [[NSMutableArray alloc] init];
