Question

MasterViewController.h:

#import <UIKit/UIKit.h>

@interface MasterViewController : UITableViewController

@property (nonatomic, strong) NSMutableArray *listOfBugs;

MasterViewController.m:

- (void)viewDidLoad
{
    [super viewDidLoad];
    _listOfBugs = [[NSMutableArray alloc]init];
}

...
...

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

{
    ScaryBugDoc *bug = [self.bugs objectAtIndex:indexPath.row];
    [_listOfBugs addObject:bug];
}

In the above code I’ve created an array that holds objects with properties.
I want to access the objects inside the array from a different class and also add objects to the same array. I know I can create a new array from the same class like this:

ListOfBugsViewController.m:

#import "ListOfBugsViewController.h"
#import "MasterViewController.h"
MasterViewController *myClass = [[MasterViewController alloc]init];


    NSMutableArray *array = [myClass.listOfBugs....

But obviously that’s not what I’m looking for. I want to access the objects that are already inside the array and not to create a new array.

Edit: To make things a bit simpler, I have a few classes and only one array I’m adding objects to. All classes should be able to add objects to it and read previously added objects.
How can I access that same array from a class it wasn’t allocated and initialized in?

Thanks

Answer 1

Adding an object to an array from other class in fairly simple.

Just see how…

Base.m

...
_baseArray=[[NSMutableArray alloc]init];
[_baseArray addObject:@"Anoop"];
[_baseArray addObject:@"kumar"];
...

OtherClass.m

Base *baseObj=[Base new];
[baseObj.baseArray addObject:@"vaidya"];

EDIT:

As per our discussion

- (void)awakeFromNib
{
    [super awakeFromNib];
    [self createObjects];

}

- (void) createObjects
{
    _listOfBugs=[[NSMutableArray alloc]init];

    [_listOfBugs addObject:@"Anoop"];

    NSLog(@"init done, %@",_listOfBugs);

}


- (id)init
{
    self = [super init];    
    if (self) {
        [self createObjects];
    }
    return self;
}
