Question

Hello!

I try to extract the values from an array (prepTime), but it don’t show them. When I compile the program I get an error:

0xec80b0:  cmpl   (%eax), %ecx        Thread 1: EXC_BAD_ACCESS (code=1, address=0xff31e10)

Here I created the array:

{
    NSArray *tableData;
    NSArray *thumbnails;
    NSArray *prepTime;    //Here I created the array
}

Here I filled it with values:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Initialize table data
    tableData = [NSArray arrayWithObjects:@"Egg Benedict", ... @"Angry Birds Cake", @"Ham and Cheese Panini", nil];

    // Initialize thumbnails
    thumbnails = [NSArray arrayWithObjects:@"egg_benedict.jpg", ... @"angry_birds_cake.jpg", @"ham_and_cheese_panini.jpg", nil];

    //Initialize prep time
    prepTime=[NSArray arrayWithObjects: @"90 min", "60 min", "45 min", ... "10 min", "60 min", "40 min",   nil];
}

As you can see there are three arrays in my code were defined and filled with values, but only ‘prepTime‘ array don’t show it values in my table cell and give an error when compile it instead.

Why it happens?

Thanks a lot!

It looks like you have missed a few @ signs in some of your string literals:

prepTime=[NSArray arrayWithObjects: @"90 min", "60 min", "45 min", ... "10 min", "60 min", "40 min",   nil];
//                                             ^Here     ^Here         ^Here     ^Here     ^Here

Trying to access the resultant C strings as NSString causes bad access.
