[__NSArrayM objectAtIndex:]: index 2 beyond bounds [0 .. 1]

Question

i'm a new iOS developer; i have an application with parse and dynamic cell but when i run the app i find that the app is crashed due to the reason on the title my code as the following

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
    
    myArray = [[NSMutableArray alloc] init];
    
    
    //create new view if no view is available for recycling
    
   // view = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 250.0f, 300.0f)] autorelease];
    
    FXImageView *imageView = [[[FXImageView alloc] initWithFrame:CGRectMake(0, 0, 250.0f, 350.0f)] autorelease];
    imageView.contentMode = UIViewContentModeScaleAspectFit;
    imageView.asynchronous = YES;
   // imageView.reflectionScale = 0.5f;
   // imageView.reflectionAlpha = 0.25f;
  //  imageView.reflectionGap = 10.0f;
    imageView.shadowOffset = CGSizeMake(0.0f, 2.0f);
    imageView.shadowBlur = 5.0f;
    imageView.cornerRadius = 10.0f;
    view = imageView;
    
    [ProgressHUD dismiss];
    
     NSString *string1 = [[NSUserDefaults standardUserDefaults] stringForKey:@"Class"];
    
    PFQuery *query = [PFQuery queryWithClassName:[NSString stringWithFormat:@"%@",string1]];
    
    
    query.cachePolicy = kPFCachePolicyNetworkElseCache;
    
    //show loader view
    
    
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            
            myArray = [[NSMutableArray alloc] initWithArray:objects];
            
            PFObject *object = [myArray objectAtIndex:index];
            
            
            [file getDataInBackgroundWithBlock:^(NSData *data1, NSError *error) {
                if (!error) {
                    
                    ((UIImageView *)view).image = [UIImage imageWithData:data1];
                    
                    //[HUD hideUIBlockingIndicator];
                    
                }
            }];
            
        }
        
    }];

    return view;

    
}

i use for first screen UICollectionView with dynamic data from parse as the following code

pragma collectionView delegate

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"cell";
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:CellIdentifier forIndexPath:indexPath];
    
    CALayer *layer = cell.layer;
    [layer setCornerRadius:8.0f];
    [layer setMasksToBounds:YES];
   // [layer setBorderWidth:1.0f];
  //  layer.backgroundColor = [UIColor whiteColor].CGColor;
    //can you click
    
    PFObject *imageObject = [myArray objectAtIndex:indexPath.item];
    PFFile *imageFile = [imageObject objectForKey:@"image"];
    NSString *name = [imageObject objectForKey:@"name"];
    
    [imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
        if (!error) {
            
            UIImageView *imageView = (UIImageView *)[cell viewWithTag:100];
            imageView.image = [UIImage imageWithData:data];
            
            UILabel *title2 = (UILabel *)[cell viewWithTag:200];
            title2.text = [NSString stringWithFormat:@"%@",name];
            title2.font = [UIFont fontWithName:@"GESSTextMedium-Medium" size:12];
        }
    }];

    
    return cell;
}

i need some help to know where is the error; every time i receive this error on console [__NSArrayM objectAtIndex:]: index 2 beyond bounds [0 .. 1]

Answer 1

finally i find the problem where; i must define the array for iCarousel numberOfItems so the code will be as the following

- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
    //return the total number of items in the carousel

    return ([myArray count]);
    return ([titleArray count]);
    return ([priceArray count]);
    return ([sapArray count]);    
}

so i escape from the index problem

thanks for all sharing with me
