NSInvalidArgumentException', reason: '-[__NSArrayI length : unrecognized selector sent to instance

Question

As I looked for answers from google and here most of the answer says that you are trying to use length on an NSArray which is not supported.

The problem here is I don't even use any NSArray or length in my code.

I got a

NSMutableArray *filteredContent;   

where filteredContent will contain dictionaries from a plist.

Everything runs great until writing cell.textLabel.text on the cell for tableView.
Checked with NSLog and the content is indeed an array.

This is how I try to write the cell text:

cell.textLabel.text=[[self.filteredContent objectAtIndex:indexPath.row] valueForKey:@"recipeName"];

But it gives me error so i changed it to:

NSString *myValue = [self.filteredContent valueForKey:@"recipeName"];
cell.textLabel.text=myValue;

Yet the result is the same. I have no idea what I am getting this error.

Further details:

[results addObject:@[recipe]];

This is where i create my main array and than pass it to the PageView with segue filteredContent = results

---

EDIT:

recipe = arrayOfPlist[i]; where arrayOfPlist

NSArray *arrayOfPlist = [[NSArray alloc] initWithContentsOfFile:path];
//Output to NSLog(@"FIltered Content :  %@", self.filteredContent);
FIltered Content :  (
        (
            {
                category = main;
                difficultyLevel = "3/5";
                numberOfPerson = 5;
                recipeDetail = "Bulguru koy su koy beklet pisir ye ";
                recipeImage = "nohutlu-pilav.jpg";
                recipeIngredients = "pirinc,tereyag tuz,bulgur";
                recipeName = "Bulgurlu Pilav";
                time = "25 dk";
            }
        ),
        (
            {
                category = main;
                difficultyLevel = "3/5";
                numberOfPerson = 5;
                recipeDetail = "Bulguru koy su koy beklet pisir ye ";
                recipeImage = "nohutlu-pilav.jpg";
                recipeIngredients = "pirinc,tereyag tuz,bulgur";
                recipeName = "Bulgurlu Pilav";
                time = "25 dk";
            }
        )
    )

Answer 1

Based on the output of your data, you have an extra array in there. So you want this:

cell.textLabel.text = self.filteredContent[indexPath.row][0][@"recipeName"];

Each element of your filteredContentArray is another array. Each of those inner arrays has the dictionary with the data you want.
