Question

have a question. I have an ipad app that contains a View Controller with a UITableView and a detail view (which is basically another view controller to display details) on the same screen. I need to pass the row data from UITableView when the -didSelectRowAtIndexPath is executed to this detail view. I am not sure how to go about doing this? Any help/pointers/sample code on how to go about doing this?

Thanks for your help in advance

Answer 1

Define a delegate in the UITableView view controller, and implement it in the detail view controller. When didSelectRowAtIndexPath is invoked, call the delegate method, passing the row data to the detail view controller.

The delegate definition will look something like:

@class MyTopLevelViewController;

@protocol MyTopLevelViewControllerDelegate <NSObject>

-(void)showDetail:(DetailObject *)detail;

@interface MyTopLevelViewController : UIViewController

@property (nonatomic, weak) id <MyTopLevelViewControllerDelegate> delegate;

@end

and adding the delegate to the detail view controller header:

@interface MyDetailViewController : UIViewController <MyTopLevelViewControllerDelegate>
