Store UITableView Information in Single NSMutableArray

Question

I am trying to store all of the items scrolled past in my UITableView in an NSMutableArray. In my cellForRowAtIndexPath method I include the code below. All of the objects (Id, currentTime, et...) are NSStrings.

I am trying to compile all of them into a single array, but I don't think I am doing this correctly. I think I might be overwriting the dictionary in every single cellForRowAtIndexPath .

Any help would be great. At the end, I just want a single array that allows me to look up various aspects of the "rows/cells" that were scrolled past...

In my .m file:

NSMutableDictionary *dict = [NSMutableDictionary dictionary];

[dict setObject:Id forKey:@"key1"];
[dict setObject:currentTime forKey:@"key2"];
[dict setObject:textForMyLabel forKey:@"key3"];
[dict setObject:placeLatitude forKey:@"key4"];
[dict setObject:placeLongitude forKey:@"key5"];

[scrolledPast addObject:dict];

NSLog(@"array: %@", dict);

In my .h file:

@interface viewController {
    NSMutableArray *scrolledPast;
}

@property (nonatomic, retain) NSMutableArray *scrolledPast;

You need to initialize your scrolledPast .

Do this in your viewDidLoad:

- (void) viewDidLoad {

    // .....
    scrolledPast = [NSMutableArray array];
}
