SwiftyFORM是一个轻量级的iOS框架，用于创建表单

支持深色模式

因为表单代码很难写，很难阅读，很难推理。周转时间很慢。维护起来很痛苦。

USAGE

Tutorial 0 - Static text

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

Tutorial 1 - TextField

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

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)
    }
}
Swift

Advanced - date picker

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()
    }
}
Swift

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
        }()
}
