Instalation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate Fastis into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '13.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'Fastis', '~> 1.0.0'
end

Then, run the following command:

$ pod install

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding Fastis as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/simla-tech/Fastis.git", .upToNextMajor(from: "1.0.0"))
]

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate Fastis into your project manually.

Usage

Quick Start

import Fastis

class MyViewController: UIViewController {

   func chooseDate() {
        let fastisController = FastisController(mode: .range)
        fastisController.title = "Choose range"
        fastisController.maximumDate = Date()
        fastisController.allowsToChooseNilDate = true
        fastisController.shortcuts = [.today, .lastWeek]
        fastisController.doneHandler = { resultRange in
            ...
        }
        fastisController.present(above: self)
    }

}

Single and range modes

If you want to get a single date you have to use Date type:

let fastisController = FastisController(mode: .single)
fastisController.initialValue = Date()
fastisController.doneHandler = { resultDate in
	print(resultDate) // resultDate is Date
}

If you want to get a date range you have to use FastisRange type:

let fastisController = FastisController(mode: .range)
fastisController.initialValue = FastisRange(from: Date(), to: Date()) // or .from(Date(), to: Date())
fastisController.doneHandler = { resultRange in
	print(resultRange) // resultDate is FastisRange
}

Configuration

FastisController have the following default configuration parameters:

var shortcuts: [FastisShortcut<Value>] = []
var allowsToChooseNilDate: Bool = false
var dismissHandler: (() -> Void)? = nil
var doneHandler: ((Value?) -> Void)? = nil
var initialValue: Value? = nil
var minimumDate: Date? = nil
var maximumDate: Date? = nil
var selectMonthOnHeaderTap: Bool = true
var allowDateRangeChanges: Bool = true

shortcuts- Shortcuts array. Default value is []. See Shortcuts section
allowsToChooseNilDate- Allow to choose nil date. If you set true done button will be wlways enabled. Default value is false.
dismissHandler- The block to execute after the dismissal finishes. Default value is nil.
doneHandler- The block to execute after "Done" button will be tapped. Default value is nil.
initialValue- And initial value which will be selected bu default. Default value is nil.
minimumDate- Minimal selection date. Dates less then current will be markes as unavailable. Default value is nil.
maximumDate- Maximum selection date. Dates greather then current will be markes as unavailable. Default value is nil.
selectMonthOnHeaderTap (Only for .range mode) - Set this variable to true if you want to allow select date ranges by tapping on months. Default value is true.
allowDateRangeChanges (Only for .range mode) - Set this variable to false if you want to if you want to disable date range changes. Next tap after selecting range will start new range selection. Default value is true.

Shortcuts

Using shortcuts allows you to quick select prepared dates or date ranges. By default .shortcuts is empty. If you don't provide any shortcuts the bottom container will be hidden.

In Fasis available some prepared shortcuts for each mode:

For .single: .today, .tomorrow, .yesterday
For .range: .today, .lastWeek, .lastMonth

Also you can create your own shortcut:

var customShortcut = FastisShortcut(name: "Today") {
	let now = Date()
	return FastisRange(from: now.startOfDay(), to: now.endOfDay())
}
fastisController.shortcuts = [customShortcut, .lastWeek]

Customization

Fastis can be customized global or local. FastisConfig have some sections:

controller - base view controller (cancelButtonTitle, doneButtonTitle, etc.)
monthHeader - month titles
dayCell - day cells (selection parameters, font, etc.)
weekView - top header view with week day names
currentValueView - current value view appereance (clear button, date format, etc.)
shortcutContainerView - bottom view with shortcuts
shortcutItemView - shortcut item in the bottom view

To cutomize all Fastis controllers in your app use FastisConfig.default:

FastisConfig.default.monthHeader.labelColor = .red

To customize special FastisController instance:

var customConfig = FastisConfig.default
customConfig.controller.dayCell.dateLabelColor = .blue
let fastisController = FastisController(mode: .range, config: customConfig)
