UITableView Edit Mode Add the cell defined by user? - iphone

Question

I wanted to use the table editing mode so that the users can choose which Cells to add.
For eg I have
addArray = {#"Red",#"Blue",#"Green"};
Now , what I want is that when user enters the editing mode and presses the add button, he gets the options: Red,Blue,Green and selects the cell to be added.
-(IBAction)addButtonPressed
{
[displayArray addObject:"User's Choice"];
[self.tableview reloadData];
}

You probably want to use a UIActionSheet (see Apple docs):
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:#"Select an option"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Red", #"Green", #"Blue", nil];
[actionSheet showInView:self.view];
You will need to make your view controller conform to the UIActionSheetDelegate protocol:
#interface MyViewController : UITableViewController <UIActionSheetDelegate>
Then, implement the actionSheet:clickedButtonAtIndex: method in your view controller:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == actionSheet.firstOtherButtonIndex) {
// Red
[displayArray addObject:"Red"];
[self.tableview reloadData];
}
else if (buttonIndex == actionSheet.firstOtherButtonIndex + 1) {
// Green
[displayArray addObject:"Green"];
[self.tableview reloadData];
}
else if (buttonIndex == actionSheet.firstOtherButtonIndex + 2) {
// Blue
[displayArray addObject:"Blue"];
[self.tableview reloadData];
}
}
