Answer 1

Your textfield is not a subview of the ViewController class's view (where you reference "self"). It's inside a particular UITAbleViewCell. So you'll have to figure out which table cell you want the textview contents from and get it out of the cell's contentview.

Moreover, you could save some trouble in the future and check that you get a view returned when asking for it, e.g.:

UIView *aView = [someView viewWithTag:1];
if( aView != nil ){
...
}else{
...
}

Answer 2

don't know if it's a typo in the question or in the code:

[self.viewWithTag:1]

but you shouldn't have a dot in there:

[self viewWithTag:1]

Answer 3

Your code for the save method should read:

-(IBAction ) saveChanges:(id) sender
{

    UITextField *name =(UITextField *)[self.view viewWithTag:1];
    UITextField *bday= (UITextField *)[self.view viewWithTag:2];

    UITextField *note=(UITextField *)[self.view viewWithTag:3];
    ////  some code ////////////
}

You are accessing a tagged subview of the view relating to the controller in which this code is placed.
