#Usage

Add DOAutocompleteTextField to your project, create an instance of it as you would create a UITextField and set the delegate.

DOAutocompleteTextField *textField = [[DOAutocompleteTextField alloc] initWithFrame:CGRectMake(0,0,100,31)];
textField.delegate = self;

In your DOAutocompleteTextFieldDelegate provide the completions according to you own logic or similar to the demo.

- (NSString *)textField:(DOAutocompleteTextField *)textField completionForPrefix:(NSString *)prefix
{
	// This is a simple example of how to provide DOAutocomleteTextField with completions
    NSArray *autocompleteArray = [NSArray arrayWithObjects:
                                  @"thesaurus",
                                  @"the weather channel",
                                  @"DoAT",
                                  @"Doctor Who",
                                  @"Dachshunds are the best",
                                  @"ccccombo breaker",
                                  @"money",
                                  @"Mona lisa",
                                  @"Monalisa",
                                  @"mcdonalds",
                                  @"mc hammer", 
                                  @"long cat is looooooooooooooooooog",
                                  nil];
    
    for (NSString *string in autocompleteArray) 
    {
        if([string hasPrefix:prefix])
        {
            return [string stringByReplacingCharactersInRange:[prefix rangeOfString:prefix] withString:@""];
        }
        
    }
    
    return @"";
}

DOAutocompleteTextField draws the completion text immediatlly after user input.

#Known Issues

  • Completion position is still a bit off.
