Question

I’m having TableView as my MainView and viewcontroller as my Second view. The view controller has 3 textfields..I’m writing protocol so that I can get the values of Textfileds and can add into array of Tableview. The purpose is Whatever I give it in the textfield must get added in to the Table cell.
I’m having secondviewcontroller.h

@property (nonatomic,assign) id<secondviewcontrollerDelegate> delegate;

 @protocol secondviewcontrollerDelegate<NSObject>
- (void)additemsintoarray;
@end

secondviewcontroller.m

-(IBAction)ok:(id)sender
{
    [self.delegate additemsintoarray];
}

In Tableview.h

@interface RootViewController : UITableViewController<secondviewcontrollerDelegate> 

in tableview.m

- (void)additemsintoarray
{
    [self.array1 insertObject:scontroller.iditem1.text atIndex:[array1 count]];
    [self.array1 insertObject:scontroller.nameitem1.text atIndex:[array1 count]];
    [self.array1 insertObject:scontroller.iditem1.text atIndex:[array1 count]];
    [[self navigationController]popViewControllerAnimated:YES];
}

Note: the array is declared in Tableview with some values….
I’m getting an Error:

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘*** -[UIView additemsintoarray:]: unrecognized selector sent to instance

Answer 1

Your RootViewController should be the delegate. You have this issue because of an UIView is connected as a delegate of your SecondViewController.

Hope this helps
