Question

when i press the new button i need to add a textfield on last row of tableview.

can any one explain the flow.

Thanks in advance.

Answer 1

Just i tried this scenario.

Create a one Boolean variable like this
BOOL newButtonPress = NO;

then fallow the below code

-(IBAction)newButtonClicked:(id)sender{
if (self.newButtonPress == NO) {
//if new button press then newbuttpress is yes and reload the tableview
self.newButtonPress = YES;
[self .reloadTableview reloadData];
    }   
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
if(self.newButtonPress == YES)//creating noOfRows when newbutton pressed
{
    return [self.itemNames count]+1;
}
else {
    return [self.itemNames count]; 
   }
}

Then add the below code into the cellForRowAtIndexPath method

//when new button is pressed adding new cell
if (self.newButtonPress == YES) {
    if([self.itemNames count] == [indexPath row]){
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        //creating the textfield if new button is pressed 
        UITextField *extraField = [[UITextField alloc] initWithFrame:CGRectMake(80, 6, 100, 30)];
        extraField.borderStyle = UITextBorderStyleNone;
        extraField.textAlignment = UITextAlignmentCenter;
        [extraField becomeFirstResponder];
        [extraField setDelegate:self];
        [cell addSubview:extraField];
        [extraField release];
    }
}
