Question

I have a view controller which contains a tableview.This tableview is displayed in the UIPopover controller in a parent view.I want the text from the selected cell in the popover controller to get set in a UITextField in the parent view and i want to dismiss the popover after selection.I am not able to achieve this.

Code of the popover controller

.h file

#import <UIKit/UIKit.h>

@protocol SelectLocationViewControllerDelegate <NSObject>

- (void)locationSelected:(NSString *)location;

@end

@interface SelectLocationViewController : UIViewController <UITableViewDataSource, UITableViewDelegate> {
    IBOutlet UITableView *locationTableView;
    NSArray *locationtypes;
    id delegate;


}

@property (nonatomic, retain) UITableView * locationTableView;
@property (nonatomic, retain) NSArray * locationtypes;
@property (nonatomic, assign) id<SelectLocationViewControllerDelegate> delegate;


@end

.m file of the popover

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    NSInteger row = [indexPath row];

    NSString *locationSelected = [self.dwellingTypes objectAtIndex:row];

    [self.delegate locationSelected: locationSelected];  // This don't gets invoked.

}

Parent Class

- (void) locationSelected:(NSString *)location {

    ----Here i set the the text for text field and dismiss the popover----
    [popoverController dismissPopoverAnimated:YES];
}

The locationselected method which is present in the parent class doesn’t gets called.

Please any body help me to over come from this issue.

Thank You

Is the popover i am creating is correct?

.h file

#import <UIKit/UIKit.h>
#import "SelectLocationViewController.h"
@interface SearchViewController : UIViewController<SelectLocationViewControllerDelegate,UIPopoverControllerDelegate>{

    SelectLocationViewController * selectLocationViewController;
    UIPopoverController * locationpopover;
    IBOutlet UITextField *locationSelectedField;

}
@property (nonatomic, retain) UIPopoverController * locationpopover;
@property (nonatomic, retain) SelectLocationViewController * selectLocationViewController;



.m file

- (void)viewDidLoad {

selectLocationViewController=[[SelectLocationViewController alloc]init];  //The class which i am displaying inside the popover
selectLocationViewController.delegate=self;
UINavigationController *navigationcontroller=[[UINavigationController alloc]initWithRootViewController: selectLocationViewController];

locationpopover = [[UIPopoverController alloc] initWithContentViewController:navigationcontroller]; 
[locationpopover setPopoverContentSize:CGSizeMake(290,410) animated:YES];
[locationpopover setDelegate:self];

}

- (void)itemSelected:(NSString *)dwelling //This is the method which is called from the other class when a row is selected from the tableview in SelectLocationViewController class
{    

    locationSelectedField.text= dwelling;
    NSLog(@"DwellingSelectedField iside tap:%@",dwelling);   //I get the text printed here
    [locationpopover dismissPopoverAnimated:YES];

}

I believe it is not called because you haven’t set your delegate property. You should check this part of code. Or if it is ok add it to your post.
