Trying to pass array of strings to destination view controller

Question

In my app I have parsed images in Collectionview cells that segue when pressed to another screen with the larger image. This works fine. But, when I try to add a label that contains an array of strings to the same destination view controller I get :

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString objectAtIndex:]: unrecognized selector sent to instance 0xaaa7520'

Each array, the image and string have the same amount of indexes.

In First View Controller

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:@"BottomSegue"]) {
    //DetailShowImageViewController *detailedVC = segue.destinationViewController;
    //detailedVC.detailImageView  =sender;


    NSArray *indexPaths = [self.bottomCollectionview indexPathsForSelectedItems];
    NSLog(@"%@", indexPaths);
    BottomCollectionDetail *destinationVC =segue.destinationViewController;
    NSIndexPath *indexPath = [indexPaths objectAtIndex:0];
    NSLog(@"%@", indexPath);

    destinationVC.imageFromArray  = [bottomArray objectAtIndex:indexPath.row];
    destinationVC.string = [arrayOfTitles objectAtIndex:indexPath.row];
    [self.bottomCollectionview deselectItemAtIndexPath:indexPath animated:YES];


}

destinationVC.h

@property (weak, nonatomic) IBOutlet UILabel *labelOne;
@property (weak, nonatomic) IBOutlet UIImageView *imageViewBCD;
@property(weak, nonatomic) NSString *string;
@property(weak, nonatomic)UIImage *imageFromArray;

destinationVC.m

- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view.
    self.imageViewBCD.image = _imageFromArray;
    self.labelOne.text = _string; //This is the line of code that is causing exception
}

My issue is trying to get the label to show the string, that is throwing the exception. Is there anyway I can fix this?

arrayOfTitles contains parsed strings. The strings are showing in NSLog in original view controller. — DaveLass

just try this self.labelOne.text = [NSString stringWithFormat:@"%@",_string] — Arun Kumar

NSInvalidArgumentException', reason: '-[__NSCFString objectAtIndex:]: unrecognized selector sent to instance 0xaaa7520' is pretty self explanatory, it's not related to releasing, the problem is that your arrayOfTiles is a NSString and not a NSArray. Check the all the places where you are creating/assigning the arrayOfTiles.

Check your arrayOfTitles it is being released at some places. check that part of code. But you can try to set these two array with strong property.

Made arrayOfTitles a strong property but still drawing exception.

Prateek Prem Over a year ago

have you checked the array at the place you add objects in it, try this: when all objects are added in the array , once checked it with log.

you can also try to use ViewWillAppear rather than viewDidLoad

The objects are in place. The issue seems to be in the prepareForSegue Method
