i m using this code to display textfield in tableview and then access the value from the textfield. Bbut getting the error in the “saveChange” method “UITextField *name =(UITextField *)[self.viewWithTag:1]” error :- view is something not a structure or a union.
plz me out of this

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{
...
}
