I have a structure like this....
UITableViewController -> UITableViewCell -> UIView
I need the UIView to access a HashTable (NSMutableDictionary) in the UITableViewController
Is there a way to access the ViewController simply from the ViewCell (using [ViewCell superview] obviously won't work) ....Do I need to go down through the AppDelegate using [[UIApplication sharedApplication] delegate]?
Thanks!
I usually maintain a weak reference from my UIView to my UIViewController if I need one, usually by creating a method something like this:
-(MyView*)initWithController:(CardCreatorViewController*) aController andFrame:(CGRect)aFrame
{
if (self = [super initWithFrame:aFrame])
{
controller = aController;
// more initialisation here
}
return self;
}
You could also use a delegate pattern if you want a more decoupled solution. I tend to think this is overkill for a view and its controller, but I would use it with a system of controllers and subcontrollers.
Some modification from Kare Morstol answer :
The hierarchy of tableviewcell is in iOS 5.0(my test version)
cell.superview = tableview
cell.superview.superview = UIViewControllerWrapperView
So, use cell.superview to get tableview. And the tableview and tableviewController has a relation of delegate, dataSource in default.
You can get tableviewController reference by tableview.delegate or tableview.dataSource.
UITableView *tableView = cell.superview;
UITableViewController *tableViewController = tableView.delegate; // or tableView.dataSource`
