Question

I can’t seem to find any information on what should be a simple issue. I have a table which contains a series of cells. When you tap on the cell it shows the information of that object in detail. I know it is possible to have a button which places all of the data on the screen in EDIT mode. Any tutorials or advice as how to do this (properly/ with best practices)?

Just to be clear this is for iPhone/ Objective-C/ Cocoa.

Thanks,

EDIT 1

Sorry. I know how to put the button there. But how do make the labels editable?

Answer 1

You cannot have editable labels. However, you can replace the label with a textfield when the button is pressed, and then update the label once finished.

One way to do this is the following. Create a textfield in the same location as the label and initially set textField.hidden = YES;. Then implement something along these lines:

-(IBAction)editMyCell:(id)sender {
  textField.text = cellLabel.text;
  cellLabel.hidden = YES;
  textField.hidden = NO;
  [textField becomeFirstResponder];
}

and when the editing has finished, restore with

-(void)textFieldDidEndEditing:(UITextField *)textField {
  cellLabel.text = textField.text;
  textField.hidden = YES;
  cellLabel.hidden = NO;
  [textField resignFirstResponder];
}

You’ll probably want to tweak this idea a bit for your situation, but it’s probably the simplest thing to implement that achieves what you’re after.
