Notice in the code below, the two NSLOG statements. The aaa gets printed out

  • 0

Notice in the code below, the two NSLOG statements. The “aaa” gets printed out but the “bbb” never does. Instead, the simulator crashes with EXC_BAD_ACCESS. I know that this typically means that the object I am trying to access has been prematurely released. I just can’t figure out what is wrong…

Updated:

here is my .h

#import <UIKit/UIKit.h>


@interface vcAddCat : UIViewController  <UIPickerViewDataSource, UIPickerViewDelegate> {

NSManagedObjectContext *managedObjectContext;

IBOutlet UIPickerView * pickerView;
NSArray * _weights;
NSArray * _categories;
IBOutlet UILabel *lastCat;
IBOutlet UILabel *lastWeight;

}

I do not have any @property or @synthesize lines for either array…

Here are two snips from my .m

- (void)viewDidLoad {

    [super viewDidLoad];
    NSLog(@">>> Entering %s <<<", __PRETTY_FUNCTION__);

    _categories=[[NSArray alloc] initWithObjects: @"Homework",@"Quizzes",@"Tests", @"Mid-Term Exam", nil];
;

    NSLog(@"aaa");

    _weights=[[NSArray alloc] initWithObjects: @"1",@"2",@"3",@"4", @"5", @"6", @"7", @"8", @"9", @"10", @"11", @"11", @"12", @"13", @"14", @"15", @"16", @"17", @"18", @"19", @"20", @"21",@"22",@"23", @"24", @"25", nil];


    NSLog(@"bbb");

..and here is where I release the arrays…

- (void)dealloc {
[super dealloc];
[_categories release];
[_weights release];
NSLog(@">>> Leaving %s <<<", __PRETTY_FUNCTION__);

}

    OK – loser alert.

    Sorry, guys. All was working when I tested early on with only 10 objects to insert. Once I got it going, I added the rest of the objects (11 – 100) and that’s when it crashed. When I posted the code above, I truncated the object list at 25 items – too redundant, it seemed.

    Well, objects 26, 36, 46, etc all had a typo in them where I’d omitted the preceding ‘@’ before the string value.

    Fixed that and I’m back on track.

    Thanks for your help and sorry about the lame error.

    Phil
