This may seem like a very simple question, however I haven’t been able to discover a simple option yet…

I have a series of UITextFields followed by a UITextView. How can I incorporated the TextFields and the TextView in the same method below.

-(BOOL) textFieldDidBeginEditing:(UITextField *) textField{
textField = activeField;
if([self.textField1 isFirstResponder]){activeField = textField1;}
else if([self.textField2 isFirstResponder]){activeField = textField2;}
else if([self.textField3 isFirstResponder]){activeField = textField3;}
else if([self.textView1 isFirstResponder]){ activeField = textView1;}

[scrollView1 scrollRectToVisible:[activeField frame] animated:YES];

return NO;
}

The last line causes a warning of:

Incompatible pointer types assigning to ‘UITextField *_strong’ from ‘UITextView *_strong’

This is due (I’m sure) to the obvious fact that the UITextField and the UITextView are different Objects… which is fine however is there a way to get around this as I wish to be able to advance through the textFields and TextViews with a next and previous button.

as per this method

-(void) nextTextField:(id)sender{
if([self.textField1 isFirstResponder]){activeField = textField2;}
else if([self.textField2 isFirstResponder]){activeField = textField3;}
else if([self.textField3 isFirstResponder]){activeField = textView1;}
else if([self.textView1 isFirstResponder]){ activeField = textField1;}
}

I was hoping for a casting sort of option however I am a little confused as to how to cast in objective C… This might sound dumb however 

activeField = ((UITextField) textView1);

is how I’d have cast in Java but it seems I just can’t seem to get he syntax right.
Should I cast to a UIView as they both inherit from that?

Thank you in advance

    Okay, so you don’t need to store activeField, for this method, so the only relevant code would be your nextTextField: method. Try changing it to:

    -(void) nextTextField:(id)sender{
          if([self.textField1 isFirstResponder]) {[textField2 becomeFirstResponder];}
     else if([self.textField2 isFirstResponder]) {[textField3 becomeFirstResponder];}
     else if([self.textField3 isFirstResponder]) {[textView1  becomeFirstResponder];}
     else if([self.textView1 isFirstResponder])  {[textField1 becomeFirstResponder];}
}

    You don’t need to cast to a different type or anything.
