iOS Code Not Running When Method Called From Other Class - ios

Question

I have a custom UITableViewCell xib that has two buttons on it. An edit button, designed to pass the info for that cell into a new view controller is the one I am currently having issues with. I create a property for the TableViewController in my custom cell, and hook up the button to this code:
-(IBAction) editItem {
self.itemsList = [[TheItemsList alloc] init];
[self.itemsList editItem];
NSLog(#"EDIT");
}
Inside TheItemsList I have this code:
-(void)editItem {
NSLog(#"EDITAGAIN");
EditItem *detailViewController = [[EditItem alloc] initWithNibName:#"EditItem" bundle:nil];
detailViewController.selectedCountry = self.selectedCountry;
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
detailViewController.therow = indexPath.row;
//Pass the selected object to the new view controller.
// Push the view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
}
The console prints my NSLog for each method, but the view does not push. This code was previously used in the didSelectForIndexPath part of the table view, so I know that the view controller it is pushing is fine, I just can't figure out what is going on here.
UPDATE:
I have it SOMEWHAT working, emphasis on the somewhat.
ItemCell.h
#import <UIKit/UIKit.h>
#import "TheItemsList.h"
#class TheItemsList;
#class ItemCell;
#protocol ItemCellDelegate <NSObject>
#required
-(void)editTheItem:(ItemCell *)theCell;
#end
#interface ItemCell : UITableViewCell
#property (assign) id <ItemCellDelegate> delegate;
#property (nonatomic, retain) IBOutlet UILabel *itemName;
#property (nonatomic, retain) IBOutlet UILabel *itemPrice;
#property (nonatomic, retain) IBOutlet UILabel *itemAisle;
#property (nonatomic, retain) IBOutlet UIImageView *thumbnail;
#property (nonatomic, retain) TheItemsList *itemsList;
#end
.m
#import "ItemCell.h"
#import "EditItem.h"
#implementation ItemCell
#synthesize itemName = _itemName;
#synthesize itemAisle = _itemAisle;
#synthesize itemPrice = _itemPrice;
#synthesize thumbnail = _thumbnail;
#synthesize itemsList, delegate;
- (void)awakeFromNib {
[super awakeFromNib];
// Initialization code
}
-(IBAction) editItem {
[self.delegate editTheItem:self];
}
#end
Now, in the TableView
.h
#import <UIKit/UIKit.h>
#import "ItemCell.h"
#class ItemCell;
#protocol ItemCellDelegate;
#interface TheItemsList : UITableViewController <ItemCellDelegate>
.m
-(void)editTheItem:(ItemCell *)theCell {
NSLog(#"EDITAGAIN");
EditItem *detailViewController = [[EditItem alloc] initWithNibName:#"EditItem" bundle:nil];
detailViewController.selectedCountry = self.selectedCountry;
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
detailViewController.therow = indexPath.row;
//Pass the selected object to the new view controller.
// Push the view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
}
What I'm running into is two problems.
1, the first item in the tableview doesn't do anything when the button is pressed.
2, the other rows will run code, but it only does it for the first row's data.

Answer 1

You should use the delegate pattern inside your UITableViewCell to delegate the button press back to the UIViewController which contains the UITableView using the cell.
In cellForRowAt:IndexPath you then retrieve the cell and set its delegate like cell.delegate = self. In the view controller you implement the delegate and handle the action.
In the cell you setup a delegate variable (var delegate: MyCellDelegate?) and inside the editItem function you make a call to the delegate like self.delegate?.editItem()

Answer 2

Your issue is basically because of this line
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
On clicking the button on the cell, it does not select the row necessarily. The button takes the touch. A way to solve this would be to find the NSIndexPath of the cell in which the button is present and then do your operations with it. A way to do is to use the cell reference that is being supplied from the editAction delegate
-(void)editTheItem:(ItemCell *)theCell
Replace [self.tableView indexPathForSelectedRow] with [self.tableView indexPathForCell:theCell]
