attaching dictionary object to UITableViewCell

I would like to know if there is a way to attach a NSDictionary object to a cell that is displayed in a UITableView, so when a cell is selected I can access the NSDictionary attached to that tableviewcell.

You should strive to decouple the data model (NSDictionary) from the view (MyCell). That's what the view controller is for - to manage the relationship between each cell and the data.

Your data model would typically be an NSArray. Each element in the array corresponds to a row in the table (the indexPath). Each NSArray element would hold an NSDictionary object (the data model) for each cell.

Sure, just make a subclass of the cell and add your dictionary. You can use a completely empty implementation as well:

// MyCell.h
@interface MyCell : UITableViewCell

@property (nonatomic, strong) NSDictionary* dictionary;

@end

// MyCell.m
@implementation MyCell
@end

Now, just make sure you set your cell class if you're using a storyboard, or register it if you're not, and then just set the dictionary when you dequeue it and read it when you get the cell back later.

You can achieve this if you subclass a UITableViewCell and create a NSDictionary property in your custom cell.

Assuming you have set this property before somewhere, here's how you retrieve it when the cell is selected:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    MyCustomCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    NSLog(@"%@",cell.dictionary); //replace "dictionary" by the name of the property you created in the subclass
}
