"Thread 1: Signal SIGARBT" Error When Running in Simulator

Question

I'm pretty new to this, but when I try to simulate on the iOS simulator it stops and then this error pops up...I added a View Controller for my a table view in my storyboard. I will include the file so you guys have enough info to help me out.

Im just trying to get my table view to display some elements of an array. A navigation controller is the root view controller and it goes right into the table view controller where I want to display the array courses.

Here is my app deligate

//AppDeligate.m

#import "AppDelegate.h"
#import "CoursesViewController.h"
#import "Courses.h"

@implementation AppDelegate{
    NSMutableArray *courses;}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions 
(NSDictionary *)launchOptions
{
    courses = [NSMutableArray arrayWithCapacity:20];
    Courses *course = [[Courses alloc] init];
    course.code = @"SFWR 3X03";
    course.units = 3;
    [courses addObject:course];
    UINavigationController *navigationController =
    (UINavigationController *)self.window.rootViewController;
    CoursesViewController *CoursesViewController =
    [[navigationController viewControllers] objectAtIndex:1];
    CoursesViewController.courses = courses;
    return YES;
}

Here is my CoursesViewController.m

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
#warning Incomplete method implementation.
    // Return the number of rows in the section.
    return [self.courses count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     
*)indexPath
{
    UITableViewCell *cell = [tableView
                             dequeueReusableCellWithIdentifier:@"PlayerCell"];
    Courses *course = [self.courses objectAtIndex:indexPath.row];
    cell.textLabel.text = course.code;
    return cell;
}

Here is my coursesviewcontroller.h

#import <UIKit/UIKit.h>

@interface CoursesViewController : UITableViewController
@property (nonatomic, strong) NSMutableArray *courses;

@end

Here is my courses.m and courses.h

#import "Courses.h"

@implementation Courses

@synthesize code;
@synthesize units;

.

#import <Foundation/Foundation.h>

@interface Courses : NSObject

@property (nonatomic, copy) NSString *code;
@property (nonatomic, assign) int units;
@end



@end

When I try to run in the simulator, it flips to the main.m file and displays the SIGARBT error on thread 1.

If I havent included enough info let me know and ill post more.

Ah that helps me a little, I'd still like to hear what you think :) — drfear, Oct 04 '12 at 16:41
check you courses array, if it contains any objects before sending to your CourseViewController — Bartu, Oct 04 '12 at 16:51

Since you're using a storyboard, you don't do anything in code to instantiate the navigation controller or your CoursesViewController (everything you posted other than the "return yes" should be deleted). To get the array into your CoursesViewController, add the following code to its viewDidLoad method:

    self.courses = [NSMutableArray arrayWithCapacity:20];
    Courses *course = [[Courses alloc] init];
    course.code = @"SFWR 3X03";
    course.units = 3;
    [courses addObject:course];
    [super viewDidLoad];
    [self.tableView reloadData];

I'm assuming that you have a property called courses (typed strong) in your .h file.

Im getting errors for navigationController not found on object NavigationController now...I updated my output from earlier if that helps...It may be an issue with my storyboard... – drfear Oct 04 '12 at 18:51
Ok, I didn't notice that you were using storyboards. What is in your storyboard and how did you get it/them there? – rdelmar Oct 04 '12 at 19:29
Okay, so I have a navigation controller which automatically pushes a table view controller and the table view controller is what I am trying to get to display this array. The table view controller is attached to other things but I'm just trying to figure out this view first lol – drfear Oct 04 '12 at 21:38
I also might want to add that everything was working before I added courses view controller. But obviously I need it or I can do anything with my table view. And the courses view controller is of subclass NSTableViewController – drfear Oct 04 '12 at 21:46
See my edited answer -- it's much easier than you're making it when you use storyboards. – rdelmar Oct 04 '12 at 22:31

Reading the comments, it's a little difficult to tell what problem you're trying to solve but this error...

'-[UITableViewController loadView] loaded the     
"fBI-R0-7j9-view-iYf-OA-4cJ" nib but didn't get a UITableView.'

...is saying that the object connected to the view outlet in your table view controller is something other than a UITableView or a subclass of UITableView. Look at that controller in your storyboard and check what view linked to.
