Requirements

• iOS 8.0+
• Swift 4.0

Installation

We recommend using CocoaPods to install our library.

Just put this in your Podfile:

pod 'RAMReel'

or Carthage users can simply add reel-search to their Cartfile:

github "Ramotion/reel-search"

Usage

In order to use our control you need to implement the following:

Types

• CellClass: Your cell class must inherit from UICollectionViewCell and implement the ConfigurableCell protocol. Or you can just use our predefined class RAMCell.
• TextFieldClass: Any subclass of UITextField will do.
• DataSource: Your type must implement the FlowDataSource protocol, with QueryType being String and ResultType being Renderable and Parsable. Or you can just use our predefined class SimplePrefixQueryDataSource, which has its ResultType set to String.

Now you can use those types as generic parameters of type declaration of RAMReel:

RAMReel<CellClass, TextFieldClass, DataSource>

Values

Next you need to create an instance of RAMReel, and for that you need the following:

• frame: CGRect: Rect, specifying where you want to put the control.
• dataSource: DataSource: the source of data for the reel.
• placeholder: String (optional): Placeholder text; by default, an empty string is used.
• hook: DataSource.ResultType -> Void (optional): Action to perform on element selection, nil by default. You can add additional hooks later, if you need multiple actions performed.

Let's use it to create an instance of RAMReel:

let ramReel = RAMReel<CellClass, TextFieldClass, DataSource>(frame: frame, dataSource: dataSource, placeholder: placeholder, hook: hook)

Adding action hooks

To add extra actions you may append DataSource.ResultType -> Void functions to RAMReel object property hooks:

ramReel.hooks.append { data in
	// your code goes here
}

Putting on the view

And the final step, showing RAMReel on your view:

ramReel.view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
yourView.addSubview(ramReel.view)

If you have visual problems, try calling prepareForViewing before showing your view.

Like this:

override func viewDidLayoutSubviews() {
	super.viewDidLayoutSubviews()
	ramReel.prepareForViewing()
}

Theming

If you want to change RAMReel look and feel, you can use theming.

To do so, you just to have to implement the Theme protocol in your class/structure and set your RAMReel object's theme property to your theme.

Or you can just use the predefined instance of type RAMTheme.

let textColor: UIColor
let listBackgroundColor: UIColor
let font: UIFont

let theme = RAMTheme(textColor: textColor, listBackgroundColor: listBackgroundColor, font: font)
