How to use:

Your calling controller should implement these 2 protocols

    @interface MyCallingController : UIViewController <IMOAutocompletionViewDataSouce, IMOAutocompletionViewDelegate>

    //Whatever...   

    @end

Then call the IMOAutocompletionViewController like this

    IMOAutocompletionViewController *acvc = [[IMOAutocompletionViewController alloc]
                                             initWithLabelString:@"Label:" 
                                             textFieldString:[self theItem] 
                                             backgroundImageName:@"sandpaperthin.png"
                                             cellColors:nil];

    [acvc setDataSource:(id<IMOAutocompletionViewDataSouce>)self];
    [acvc setDelegate:(id<IMOAutocompletionViewDelegate>)self];


    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:acvc];
    [[self navigationController] presentModalViewController:navController animated:YES];
    [acvc release];
    [navController release];

Initializer arguments:

  • labelString is the textfield caption label
  • textFieldString is to populate the UITextfield
  • pass a background image (pass nil for default background)
  • cell color dictionary (pass nil for default colors)

Other initializer are overriden and call the designated initializer with default arguments (nil).
Old version's designated initializer calls the new version's one.

  • set yourself as datasource and delegate for the controller

A navigation controller is required since the cancel button is the navigationItem rightBarButtonItem

You then need need to implement those 2 methods

1 - provide a list of possible completions

    - (NSArray *)sourceForAutoCompletionTextField:(IMOAutocompletionViewController *)asViewController 
    {
        return myListOfPossibleCompletionWords;
    }

2 - intercept back the controller completion word

    - (void)IMOAutocompletionViewControllerReturnedCompletion:(NSString *)completion 
    {
        [self setTheThingThatNeedsCompletion:completion];
    }

If you want to provide your own cell colors, just pass a dictionary like this to the cellColors argument

     NSDictionary *cellColors = @{
                IMOCompletionCellTopSeparatorColor: [UIColor whiteColor],
             IMOCompletionCellBottomSeparatorColor: [UIColor colorWithRed:0.885 green:0.788 blue:0.767 alpha:1.000],
                  IMOCompletionCellBackgroundColor: [UIColor colorWithRed:0.961 green:0.914 blue:0.864 alpha:1.000]};
