IBAction not returning?

[Coolio098]

Hey everyone!

Here I have the following code for a button:

- (IBAction)courseNameConfirm:(id)sender {
	arrayCount = arrayPosition;
	id object1 = [courseData objectAtIndex:arrayCount];
	
	for (int i = 0; i < 100; i++) {
		if ([[object1 objectAtIndex:i] isEqualToString:@""]) {
			[object1 insertObject:courseNameField.text atIndex:i];
			break;
		}
	}

	return courseData;
	
	[self.tableView reloadData];
	
	[gradeSummaryNavigation dismissModalViewControllerAnimated:YES];
	
}

The mutablearray "courseData" is declared in the header file. The issue comes in where courseData returns nil when I try to use it anywhere else in the .m file but everything works fine within this function. Any idea?

"IBAction" methods don't return anything. The symbol IBAction is actually converted to "void" by the preprocessor.

How would I be able to access my array in a different part of the .m file?

Disregard the call view question I found out how to do it. Now here is where I am extremely confused. I have the following code:

- (void)viewWillAppear:(BOOL)animated {
	[super viewWillAppear:YES];

	if (courseCount == 0) {
		courseCount++;
	}
	else {
		[self courseDataAdd];
		NSLog(@"%@", [courseData objectAtIndex:0]);

	}
}

- (IBAction)courseNameConfirm:(id)sender {
	
	[self courseDataAdd];
	
	[self.tableView reloadData];

	[gradeSummaryNavigation dismissModalViewControllerAnimated:YES];
	
}

- (void)courseDataAdd {
	
	arrayCount = arrayPosition;
	id object1 = [courseData objectAtIndex:arrayCount];
	
	for (int i = 0; i < 100; i++) {
		if ([[object1 objectAtIndex:i] isEqualToString:@""]) {
			[object1 insertObject:courseNameField.text atIndex:i];
			break;
		}
	}
	[self.tableView reloadData];
}

Now when I press my button for the courseNameConfirm method, it calls the courseDataAdd method with no problems and it displays the values on my table. However, when I try to call the same courseDataAdd method in viewWillAppear, it returns the value of my array as (null). Could this be due to a presentModalViewController? If not, what are some of your thoughts? Any help would be greatly appreciated!
