XCode- Send data and Close Popover from Master View Controller

Hello,

Recently I was working on the app, where there was a button in toolbar which opens the Pop over with a table view. After selecting table cell, we need to pass some information to master view controller and close the Popover.

First you need a reference in your master view controller. Add following to your View controller header file.

@property (nonatomic, strong) UIPopoverController *myPopOver;

Synthesize it in .m file.

@implementation masterViewController

@synthesize myPopOver; 

@end

Now add prepareForSegue method.

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

{ 

   

    if([segue.identifier isEqualToString:@"popOverSegue"]){

        UIStoryboardPopoverSegue *popoverSegue = (UIStoryboardPopoverSegue *)segue;

        self.myPopOver = popoverSegue.popoverController;

        [segue.destinationViewController setDelegate:self];

    }

    

}

Also add one call call back method in your master view controller, which will be invoked when user selects a cell in pop over table view.

-(void)myCallBack{

}

Now in pop over table view controller import your master view controller and set delegate as follow.

#import

#import "masterViewController.h"

@interface myPopOverController : UITableViewController 

@property (nonatomic, weak) masterViewController* delegate;

@end

Add following code to .m file

#import "myPopOverController.h"

#import "masterViewController.h"

@interface  myPopOverController ()<UITableViewDelegate>

@end

@implementation iPadCategoriesPopOver

@synthesize categoriesArray,categoriesTableView,delegate;

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

{

    

        [[self delegate] myCallBack];

    

}

@end

Check above code carefully, here we have delegate of type mater view controller and using it to invoke our call back function, Above code is executed when some one selects a row from table view. Now add following code to myCallBack function to close the pop over.

[self. myPopOver dismissPopoverAnimated:YES];

Also note that you can pass any parameter in callback if you want.

Hope this helps you.
