I'm studying iOS programming and I am implementing MLPAutoCompleteTextField to my simple app. I followed instructions and also referred to the sample project. But when I build & run my project, it is successfully compiled but the suggestions are not displayed. Here's how it looks:http://d.pr/i/Uv3D

AddQuoteViewController.h

#import <UIKit/UIKit.h>
#import "MLPAutoCompleteTextFieldDataSource.h"
#import "MLPAutoCompleteTextFieldDelegate.h"

@class MLPAutoCompleteTextField;
@interface AddQuoteViewController : UIViewController <UITextFieldDelegate, MLPAutoCompleteTextFieldDataSource, MLPAutoCompleteTextFieldDelegate>

@property (strong, nonatomic) IBOutlet MLPAutoCompleteTextField *authorTextField;
- (IBAction)saveQuoteButton:(id)sender;
@end

AddQuoteViewController.m

#import "AddQuoteViewController.h"
#import "MLPAutoCompleteTextField.h"
#import "AuthorAutoSuggestTableViewCell.h"
#import <QuartzCore/QuartzCore.h>

@implementation AddQuoteViewController
- (void)viewDidLoad {
    [super viewDidLoad];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShowWithNotification:) name:UIKeyboardDidShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHideWithNotification:) name:UIKeyboardDidHideNotification object:nil];

    [self.authorTextField setBorderStyle:UITextBorderStyleRoundedRect];
}

- (void)keyboardDidShowWithNotification:(NSNotification *)aNotification {
    [self.author setAlpha:0];
}

- (void)keyboardDidHideWithNotification:(NSNotification *)aNotification {
    [self.author setAlpha:1];
    [self.authorTextField setAutoCompleteTableViewHidden:NO];
}

- (NSArray *)possibleAutoCompleteSuggestionsForString:(NSString *)string {
    NSArray *sample = @[@"Ape", @"Bird", @"Cat", @"Dog"];
    return sample;
}

- (BOOL)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
          shouldConfigureCell:(UITableViewCell *)cell
       withAutoCompleteString:(NSString *)autocompleteString
         withAttributedString:(NSAttributedString *)boldedString
            forRowAtIndexPath:(NSIndexPath *)indexPath;
{
    return YES;
}

Hi, I'm trying to move down the autocomplete table view, since it appears in the middle of the AutoCompleteTextfield and covers half of the text. Is there any property or method to achieve this ? I tried with autoCompleteTableOriginOffset/setAutoCompleteTableOriginOffset (in both viewWillAppear and viewDidLoad), but nothing moves or changes.

I'm using XCode Version 5.1.1 (5B1008), iOS 7.1.1 with storyboard.

Thanks

I am fairly new to IOS, and am sure I am missing something. I am unable to connect the autoCompleteDataSource to my IBOutlet in my view, but I can manually connect it by calling setAutoCompleteDataSource. Relevant code is below.

GBProductAutocomplete.h

#import <Foundation/Foundation.h>
#import "MLPAutoCompleteTextFieldDataSource.h"

@interface GBProductAutocomplete : NSObject <MLPAutoCompleteTextFieldDataSource>

@end

GBProductAutocomplete.m

#import "GBProductAutocomplete.h"

@implementation GBProductAutocomplete

- (void)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
 possibleCompletionsForString:(NSString *)string
            completionHandler:(void (^)(NSArray *))handler
{
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
    dispatch_async(queue, ^{
        NSArray *completions;
        completions = [NSArray arrayWithObjects:@"hello", @"world", nil];

        handler(completions);
    });
}

@end

GBViewController.h

#import <UIKit/UIKit.h>
#import "MLPAutoCompleteTextFieldDelegate.h"

@class GBProductAutocomplete;
@interface GBManualAddViewController : UIViewController <UITextFieldDelegate, MLPAutoCompleteTextFieldDelegate>

@property (weak, nonatomic) IBOutlet MLPAutoCompleteTextField *autocompleteTextField;
@property (strong, nonatomic) IBOutlet GBProductAutocomplete *autocompleteDataSource;
@property (weak, nonatomic) IBOutlet MLPAutoCompleteTextField *textField;

@end

GBViewController.m

#import "GBManualAddViewController.h"
#import "MLPAutoCompleteTextField.h"
#import "GBProductAutocomplete.h"

@interface GBManualAddViewController ()

@end

@implementation GBManualAddViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
//    [self.textField setAutoCompleteDataSource:[[GBProductAutocomplete alloc] init]];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (BOOL)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
          shouldConfigureCell:(UITableViewCell *)cell
       withAutoCompleteString:(NSString *)autocompleteString
         withAttributedString:(NSAttributedString *)boldedString
        forAutoCompleteObject:(id<MLPAutoCompletionObject>)autocompleteObject
            forRowAtIndexPath:(NSIndexPath *)indexPath;
{
    //This is your chance to customize an autocomplete tableview cell before it appears in the autocomplete tableview
    NSString *filename = [autocompleteString stringByAppendingString:@".png"];
    filename = [filename stringByReplacingOccurrencesOfString:@" " withString:@"-"];
    filename = [filename stringByReplacingOccurrencesOfString:@"&" withString:@"and"];
    [cell.imageView setImage:[UIImage imageNamed:filename]];

    return YES;
}

- (void)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
  didSelectAutoCompleteString:(NSString *)selectedString
       withAutoCompleteObject:(id<MLPAutoCompletionObject>)selectedObject
            forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if(selectedObject){
        NSLog(@"selected object from autocomplete menu %@ with string %@", selectedObject, [selectedObject autocompleteString]);
    } else {
        NSLog(@"selected string '%@' from autocomplete menu", selectedString);
    }
}

@end

If I uncomment the line [self.textField setAutoCompleteDataSource:[[GBProductAutocomplete alloc] init]]; in viewDidLoad the autocomplete will work, but I cannot figure out why I cannot drag from the outlet in the nib to connect the property.

For the app I'm working on, there is a form with some textfields. The autocomplete works without a problem inside a regular view in a view controller, but there are some z-index issues when the autocomplete textfield is inside a static cell of a UITableView.

It's hard to show with screenshots, but you can see the form below with the autocomplete suggestions showing up. When you try and click on one it dismisses the dialog and selects the MRN field below the suggestions.

I implement simple datasource for autocomplete list and show suggestions, but when i try to select one of the suggestion it do nothing.

I also try to implement some delegate methods like:

- (void)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
  didSelectAutoCompleteString:(NSString *)selectedString
       withAutoCompleteObject:(id<MLPAutoCompletionObject>)selectedObject
            forRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"select: %@", selectedString);
}

Nothing happens.

Trying to switch from iOS 7.1 to iOS 8, I noticed that the autoCompleteTableView doesn't appear anymore. I double checked that data is fetched correctly, so it should be something related to the tableview's visibility. Instead of the tableview, only a bottom shadow appears.

Before typing

After typing

I'm on OSX 10.9.5 (Mavericks), using XCode 6.0.1 (6A317) My app is written with Objective-C, no swift at all.

The dropdown will be attached to the rootview instead of the superview. That way dropdown items can be selected even when placed in a UITableView. Positioning in a UITableView has also been fixed.

Modified data source method to use blocks, this should allow async fetching of suggestions list which is more suitable when list is available from a web service

I'm testing on an iPad 1 running iOS 5.1. There is a concurrency problem where a crash occurs in MLPAutoCompleteFetchOperation because sentinelSemaphore is signalled in -[MLPAutoCompleteFetchOperation cancel] while it is nil because it has never been created.

If a MLPAutoCompleteTextFieldDelegate doesn't implement autoCompleteTextField:possibleCompletionsForString:completionHandler: then the semaphore will never be created in -[MLPAutoCompleteFetchOperation main]. Therefore if the user is typing fast enough that fetchAutoCompleteSuggestions gets called a second time while there is an operation on the queue, it will get cancelled which will call the operation's cancel method which attempts to signal the semaphore which was never created.

I suggest putting a guard to make sure the semaphore isn't nil in the -[MLPAutoCompleteFetchOperation cancel] method like so:

- (void) cancel
{
    if (sentinelSemaphore) dispatch_semaphore_signal(sentinelSemaphore);
    [super cancel];
}

hi Eddy, i've applied these lines of code : self.autoCompleteTableView.layer.masksToBounds=NO; self.autoCompleteTableView.layer.shadowOffset=CGSizeMake(1,1); self.autoCompleteTableView.layer.shadowRadius=5.0f; self.autoCompleteTableView.layer.shadowOpacity=1; self.autoCompleteTableView.layer.shadowColor=[UIColor orangeColor].CGColor;

in the method -setNoneStyleForAutoCompleteTableView but,i couldn't see them on the tableview.

I use cocoapod and added all your files per instruction. Yet when I run the app I get Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString asciiLevenshteinDistanceWithString:]: unrecognized selector sent to instance 0x9d5bb40'

Any idea?

Set the attachmentView property is the containerview(sample:superview, superview[.superview...].superview, UIScorllView, UITableView, UICollectionView, etc.). The pop menu should be show at front and fix MLPAutoCompleteTextField at UITableViewCell bug.

这个合并请求是添加一个attachmentView属性，只要设置attachmentView为MLPAutoCompleteTextField容器view（可以是textfield的superview或者UIScrollView，UITableView，UICollectionView等），就可以修复在UITableViewCell使用MLPAutoCompleteTextField的bug。

I've found that the didSelectAutoComplete method requires a several sec press in to trigger. Is there any Delegate methods to adjust the length of the press? Or is this adjusted somewhere else?

As you can see the suggestions drop-down is showing behind message view (shown by the red arrow). Can you fix it so that the drop-down, always shows at the top?

The MLPAutoCompleteTextField and the message UITextView, both are inside a StackView.

Dear Eddy Borja

Asynchronous managing of a drop down table of autocomplete suggestions crashes in Swift3.x

NSAssert(0, @"An autocomplete datasource must implement either autoCompleteTextField:possibleCompletionsForString: or autoCompleteTextField:possibleCompletionsForString:completionHandler:"); But same works perfectly in Swift 2.x. Probably Apple change logics again. Please check.

It has been more than 2 years after update of your github repository.

Could you please address this issue.

Waiting so much, thank you
