cameraViewController.m - return number of rows in section.

The error message i am getting is as follows - No visible @interface for 'NSString' declares the variable 'count'

// Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    // Return the number of rows in the section.
    return [self.friends count];          <---- *ERROR LINE*

}

Ok i seem to have solve it in interface by declaring friends as an NSArray.

cameraViewController.h

@property (nonatomic, strong) UIImagePickerController *imagePicker;
@property (nonatomic, strong) UIImage *image;
@property (nonatomic, strong) NSString *videoFilePath;
@property (nonatomic, strong) NSArray *friends;  -------> Was NSString *friends;
@property (nonatomic, strong) PFRelation *friendsRelation;

I think your self.friends property is set to a NSString object which does not contain a count method. Maybe you can try NSArray. Happy Coding!
