Here is the code:
- (IBAction)textFieldDidBeginEditing:(UITextField *)textField
{
NSLog(@"Inside textfieldDidBeginEditing");
textFieldBeingEdited = textField;
}
//==============================================================================
-(IBAction)textFieldDoneEditing:(id)sender
{
textFieldBeingEdited = NULL;
[sender resignFirstResponder];
if (moveViewUp)
{
[self scrollTheView:NO];
}
}
//==============================================================================
-(void)keyboardWillShow:(NSNotification *)notif
{
NSLog(@"Inside keyborad will show");
NSDictionary *info = [notif userInfo];
NSValue *aValue = [info objectForKey:UIKeyboardFrameBeginUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
float bottomPoint = (textFieldBeingEdited.frame.origin.y + textFieldBeingEdited.frame.size.height /*+ 20*/);
scrollAmount = keyboardSize.height - (self.view.frame.size.height- bottomPoint);
if(scrollAmount > 0)
{
moveViewUp = YES;
[self scrollTheView:YES];
}
else
{
moveViewUp = NO;
}
}
Here is the screen shot of the view controller
when I tap on any one of these text fields. An exception is thrown

please help
Shouldn’t the method signature be:
i.e. (void) instead of (IBAction)
