SwiftyFORM


Build Status Version License Platform Carthage compatible

SwiftyFORM is an iOS framework for creating forms.

Because form code is hard to write, hard to read, hard to reason about. Has a slow turn around time. Is painful to maintain.

USAGE

Tutorial 0 - Static text

import SwiftyFORM
class MyViewController: FormViewController {
    override func populate(_ builder: FormBuilder) {
        builder += StaticTextFormItem().title("Hello").value("World")
    }
}

Tutorial 1 - TextField

import SwiftyFORM
class MyViewController: FormViewController {
    override func populate(_ builder: FormBuilder) {
        builder += TextFieldFormItem().title("Email").placeholder("Please specify").keyboardType(.emailAddress)
    }
}

Tutorial 2 - Open child view controller

import SwiftyFORM
class MyViewController: FormViewController {
    override func populate(_ builder: FormBuilder) {
        builder += ViewControllerFormItem().title("Go to view controller").viewController(FirstViewController.self)
    }
}

Advanced - date picker

DatePicker with prev button and next button

class DatePickerBindingViewController: FormViewController {
    override func populate(_ builder: FormBuilder) {
        builder += datePicker
        builder += incrementButton
        builder += decrementButton
        builder += SectionFormItem()
        builder += summary
        updateSummary()
    }

    lazy var datePicker: DatePickerFormItem = {
        let instance = DatePickerFormItem()
        instance.title = "Date"
        instance.datePickerMode = .date
        instance.behavior = .expandedAlways
        instance.valueDidChangeBlock = { [weak self] _ in
            self?.updateSummary()
        }
        return instance
    }()

    lazy var incrementButton: ButtonFormItem = {
        let instance = ButtonFormItem()
        instance.title = "Next Day"
        instance.action = { [weak self] in
            self?.increment()
        }
        return instance
    }()

    lazy var decrementButton: ButtonFormItem = {
        let instance = ButtonFormItem()
        instance.title = "Previous Day"
        instance.action = { [weak self] in
            self?.decrement()
        }
        return instance
    }()

    lazy var summary: StaticTextFormItem = {
        return StaticTextFormItem().title("Date").value("-")
    }()

    func updateSummary() {
        summary.value = "\(datePicker.value)"
    }

    func offsetDate(_ date: Date, days: Int) -> Date {
        var dateComponents = DateComponents()
        dateComponents.day = days
        let calendar = Calendar.current
        guard let resultDate = calendar.date(byAdding: dateComponents, to: date) else {
            return date
        }
        return resultDate
    }

    func increment() {
        datePicker.setValue(offsetDate(datePicker.value, days: 1), animated: true)
        updateSummary()
    }

    func decrement() {
        datePicker.setValue(offsetDate(datePicker.value, days: -1), animated: true)
        updateSummary()
    }
}

Advanced - Validation

Change password form

class ChangePasswordViewController: FormViewController {
    override func populate(_ builder: FormBuilder) {
        builder.navigationTitle = "Password"
        builder += SectionHeaderTitleFormItem().title("Your Old Password")
        builder += passwordOld
        builder += SectionHeaderTitleFormItem().title("Your New Password")
        builder += passwordNew
        builder += passwordNewRepeated
        builder.alignLeft([passwordOld, passwordNew, passwordNewRepeated])
    }

    lazy var passwordOld: TextFieldFormItem = {
        let instance = TextFieldFormItem()
        instance.title("Old password").password().placeholder("required")
        instance.keyboardType = .numberPad
        instance.autocorrectionType = .no
        instance.validate(CharacterSetSpecification.decimalDigitCharacterSet(), message: "Must be digits")
        instance.submitValidate(CountSpecification.min(4), message: "Length must be minimum 4 digits")
        instance.validate(CountSpecification.max(6), message: "Length must be maximum 6 digits")
        return instance
        }()

    lazy var passwordNew: TextFieldFormItem = {
        let instance = TextFieldFormItem()
        instance.title("New password").password().placeholder("required")
        instance.keyboardType = .numberPad
        instance.autocorrectionType = .no
        instance.validate(CharacterSetSpecification.decimalDigitCharacterSet(), message: "Must be digits")
        instance.submitValidate(CountSpecification.min(4), message: "Length must be minimum 4 digits")
        instance.validate(CountSpecification.max(6), message: "Length must be maximum 6 digits")
        return instance
        }()

    lazy var passwordNewRepeated: TextFieldFormItem = {
        let instance = TextFieldFormItem()
        instance.title("Repeat password").password().placeholder("required")
        instance.keyboardType = .numberPad
        instance.autocorrectionType = .no
        instance.validate(CharacterSetSpecification.decimalDigitCharacterSet(), message: "Must be digits")
        instance.submitValidate(CountSpecification.min(4), message: "Length must be minimum 4 digits")
        instance.validate(CountSpecification.max(6), message: "Length must be maximum 6 digits")
        return instance
        }()
}

INSTALLATION

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

You can install it with the following command:

$ gem install cocoapods

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

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

pod 'SwiftyFORM'

Then, run the following command:

$ pod install

Carthage

Link to demo project that shows a minimal SwiftyFORM app using Carthage.

To integrate SwiftyFORM into your Xcode project using Carthage, specify it in your Cartfile:

github "neoneye/SwiftyFORM" ~> 1.4

Then, run the following command:

$ carthage update

Finally, add SwiftyFORM.framework (will be built by Carthage under Carthage/Build/iOS/) to your project's Linked Frameworks and Libraries in the General tab, and add a new Run Script Build Phase:

  • Set /bin/bash as the shell
  • write /usr/local/bin/carthage copy-frameworks in the script body
  • add $(SRCROOT)/Carthage/Build/iOS/SwiftyFORM.framework to the input files
