To run the example project, clone the repo, and run pod install from the Example directory first.

• Xcode >= 7
• iOS >= 8.0

UITextField_AutoSuggestion is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "UITextField_AutoSuggestion"

You can use library this way:

1. Conform to UITextFieldAutoSuggestionDataSource:

   @interface ViewController () <UITextFieldAutoSuggestionDataSource>

2. Set data source to some UITextField and start observing changes

   // `fieldIdentifier` is optional
   self.textField.autoSuggestionDataSource = self;
   self.textField.fieldIdentifier = @"FIELD_ID";
   [self.textField observeTextFieldChanges];

3. Implement required data source methods

   #pragma mark - UITextFieldAutoSuggestionDataSource
   
   - (UITableViewCell *)autoSuggestionField:(UITextField *)field tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath forText:(NSString *)text {
       static NSString *cellIdentifier = @"AutoSuggestionCell";
       UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
       
       if (!cell) {
           cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
       }
       
       // configure cell
       cell.textLabel.text = DATA[indexPath.row];
       
       return cell;
   }
   
   - (NSInteger)autoSuggestionField:(UITextField *)field tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section forText:(NSString *)text {
       return DATA.count;
   }

4. Implement optional data source methods if needed

   - (void)autoSuggestionField:(UITextField *)field textChanged:(NSString *)text {
   	// can be useful in some scenarious, see example project
       [self loadDataFromInternet];
   }
   
   - (CGFloat)autoSuggestionField:(UITextField *)field tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath forText:(NSString *)text {
       return 50;
   }
   
   - (void)autoSuggestionField:(UITextField *)field tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath forText:(NSString *)text {    	    
   	// do something if suggestion row selected
   	NSLog(@"%@", DATA[indexPath.row]);
   }
