How do you set the text of a label to an array value? - objective-c

Question

I would like to set a value of my array to a label.
Array declaration:
//
// ViewController.h
// Cornell Notes
//
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController{
NSString *details[8][8];
NSString *subtitles[8];
}
I am not allowed to do:
self.label.text = subtitles[0];
How can I do this?

Answer 1

This:
#interface ViewController : UIViewController{
NSString *details[8][8];
NSString *subtitles[8];
}
Should Be:
#interface ViewController : UIViewController
#property (strong, nonatomic) NSMutableArray *details;
#property (strong, nonatomic) NSMutableArray *subtitles;
You could declare it similar to the way you had it, but I believe this is the preferred current syntax. Others may correct me on this. Most important is that we declare NSMutableArray's as opposed to NSString's. You are doing C-style declarations, which will be a bit different with these. I chose NSMutableArray as opposed to NSArray because it looks like you want to be able to add objects at runtime.
And this:
self.label.text = subtitles[0];
should be:
if (!_subtitles) _subtitles = [NSMutableArray new];
[_subtitles insertObject:self.label.text atIndex:0];
This line:
if (!_subtitles) _subtitles = [NSMutableArray new];
Is just to make sure that our _subtitles dictionary exists, and if it does, we make sure that it isn't overwritten. the [NSMutableArray new] syntax is something that I personally like because it looks clean; however, many prefer [[NSMutableArray alloc]init]. Just so you're aware.
