Question

I have a view which contains a tableview, (i call this view the EquationView, and its controller the EquationViewController). The table view cells are custom cells with a label and a textfield, representing a variable and its value, receptively. I have been able to get my custom keyboard to apear when editing begins in the textfield.

However, I haven’t been able to get the keystrokes to apear in the correct cell, do to the fact that I haven’t been able figure out how to send the indexPath of the cell with textfield being edited to the custom keyboard controller class. I have included my EquationViewController.h file in my custom keyboard controller class and have been able to change the text in the tableview’s textFields by manually setting the indexPath to a specified row. Here is the keyboard class definition:

#import <UIKit/UIKit.h>
#import "EquationViewController.h"


@interface CustomNumberPadViewController : UIViewController {
    EquationViewController *equationViewController;
}
@property (nonatomic, retain) EquationViewController *equationViewController;

-(IBAction)buttonPressed:(id)sender;

@end

My action method looks like this (so far):

-(IBAction)buttonPressed:(id)sender{

    VariableCell *cell = (VariableCell *)[equationDetailViewController.myTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];

    cell.variableValue.text = @"test";

}

This get the word “test” to appear on whichever row I set in the index path.

So what I’m wondering is, is there a way to pass/get the indexPath of the cell whose textField is being edited to the action method in my custom keyboard controller class?

Answer 1

Why don’t you set your UIViewController as the delegate of your UITextFields and catch the textFieldDidBegin: delegate method?
