textField.delegate = self;

// 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",

nil];
for (NSString *string in autocompleteArray)
