Highly configurable autocomplete view that is attachable to any UITextField

luautocompleteview's Issues

Adjust Textfield position when typing.

I have integrated AutocompleteView in Table cell. So when I am typing in textfield the dropdown is not visible as keypad is open.
I do not want to hide the keypad. I want to adjust the position of textfield(Tableview).
Before Scroll

After Scroll

Just in the read me....

If you just add one tiny little line it may be helpful to people!

view.addSubview(autoCompleteView)

Thanks for this, it's awesome and super handy!

Issue with Constraints

*** Terminating app due to uncaught exception 'NSGenericException', reason: 'Unable to activate constraint with anchors <NSLayoutXAxisAnchor:0x1c0c6f180 "LUAutocompleteView.LUAutocompleteView:0x109e991f0.leading"> and <NSLayoutXAxisAnchor:0x1c0c61480 "UITextField:0x10a0f7400.leading"> because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal.'

I have a textfield in a cell in a static table view, and I got this error after setting autocompleteView.textField = myTextField in viewDidLoad()

Suggestion: left image for each cell

It would be very good to use left images for each cell.
Also background can be dimmed while selecting an item from the list.

Thank you.

Use of unresolved identifier "elements"

fileprivate let elements = (1...100).map { "\($0)" }

I have declared it above

extension ViewController: LUAutocompleteViewDataSource {
func autocompleteView(_ autocompleteView: LUAutocompleteView, elementsFor text: String, completion: @escaping ([String]) -> Void) {

// error found on this line.
let elementsThatMatchInput = elements.filter { $0.lowercased().contains(text.lowercased()) }
completion(elementsThatMatchInput)
}
}

Sugestion after focus

Hi,

is feature that open sugestion view after user touch edittext?

Cannot convert value of type '[String : AnyObject]?' to expected argument type '[NSAttributedStringKey : Any]?'

Cannot convert value of type '[String : AnyObject]?' to expected argument type '[NSAttributedStringKey : Any]?'

I had changed:
public var textAttributes: [String: Any]?

To

public var textAttributes: [NSAttributedStringKey : Any]?

subView background colour change?

I've changed the background colour to the cell, but when the cells are removed you can see the white view behind retracting.

Background colour of cell all ok

When clearing textField it exposed the white view that I'm unable to change the colour of?

Feature Request: Show all suggestions on tap

I'd love to see an option to show all suggestions when a textfield is tapped. So when a textfield is currently blank, and a user taps it, it would dropdown showing all suggestions. Then if they start typing it would refine as normal.

Some times class constraints facing conflicts after textview responding

After implementing the LUAutocompleteView, its working fine most of the time. But, sometimes the constraints issue is coming after the responding textfield which delegate with LUAutocompleteView. That is, what are the subView constraints which depends or neighbour for that textfield will not working.

Sample log:
( "<NSLayoutConstraint:0x60000048da20 V:[UITextField:0x7f9ff31de600]-(5)-[UIImageView:0x7f9ff25b6290] (active)>", "<NSLayoutConstraint:0x60000048db10 UILabel:0x7f9ff25be000'Certification Number'.height == UILabel:0x7f9ff25bdd20'Certification Name'.height (active)>", "<NSLayoutConstraint:0x60000048db60 V:[UIImageView:0x7f9ff25b6290]-(15)-[UILabel:0x7f9ff25be000'Certification Number'] (active)>", "<NSLayoutConstraint:0x60000048dc00 V:[UILabel:0x7f9ff25be000'Certification Number']-(10)-[UITextField:0x7f9ff31a8800] (active)>", "<NSLayoutConstraint:0x60000048dcf0 V:[UITextField:0x7f9ff31a8800]-(5)-[UIImageView:0x7f9ff25b6b00] (active)>", "<NSLayoutConstraint:0x60000048dde0 V:[UIImageView:0x7f9ff25b6b00]-(15)-[UILabel:0x7f9ff25bb010'Issue Date'] (active)>", "<NSLayoutConstraint:0x60000048de80 V:[UILabel:0x7f9ff25bb010'Issue Date']-(10)-[UITextField:0x7f9ff31db200] (active)>", "<NSLayoutConstraint:0x60000048df70 V:[UITextField:0x7f9ff31db200]-(5)-[UIImageView:0x7f9ff25bbc10] (active)>", "<NSLayoutConstraint:0x60000048e060 UILabel:0x7f9ff25be2e0'Country'.height == UILabel:0x7f9ff25bdd20'Certification Name'.height (active)>", "<NSLayoutConstraint:0x60000048e0b0 V:[UIImageView:0x7f9ff25bbc10]-(15)-[UILabel:0x7f9ff25be2e0'Country'] (active)>", "<NSLayoutConstraint:0x60000048e150 V:[UILabel:0x7f9ff25be2e0'Country']-(10)-[UITextField:0x7f9ff31ba000] (active)>", "<NSLayoutConstraint:0x600000495130 V:[UITextField:0x7f9ff31de600]-(0)-[MyProj..LUAutocompleteView:0x7f9ff24bd740] (active)>", "<NSLayoutConstraint:0x60000049d7e0 V:[UITextField:0x7f9ff31ba000]-(0)-[MyProj.LUAutocompleteView:0x7f9ff24bd740] (active)>" )

Sorry for English!

Feature to select search results using keyboard up and down arrow keys.

Am using Bluetooth keyboard for my app.

As the left and right arrow keys move the cursor in the text-field, using up and down arrow keys should select entries in the search result, and pressing return should select the entry and fill it in text-field.

Is it possible?

feature: add cellforrow to the delegate

Hi.

I want to use a full custom TableViewCell, and be able to set some fields.

So, ideally, I need a delegate for cellForRowAt :)

Thanks!
