Xcode Compile Error "expected method to read array element not found on
object of type NSArray"

I am new to xcode, and I try to play with UITableView to show content in
array.
I try to put some array inside Feed, and try to show them in table.
but the error is hinted at this instances
(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
on cell.textLabel.text = self.imageTitleArray[indexPath.row];
it says expected method to read array element not found on object of type
NSArray
this is my H files
#import <UIKit/UIKit.h>
@interface FeedTableViewController : UITableViewController
@property (strong, nonatomic) NSArray *imageTitleArray;
@end
and this is my M files
#import "FeedTableViewController.h"
@interface FeedTableViewController ()
@end
@implementation FeedTableViewController
- (id) initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle
*)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Feed";
self.imageTitleArray = @[@"Image 1",@"Image 2",@"Image 3", @"Image
4",@"Image 5"];
}
return self;
