ReactiveSwift + SwiftValidators

想要在 ReactiveSwift 中使用 SwiftValidators？ SwiftValidatorsReactiveExtensions 提供了一组扩展，与 ValidatingProperty 稳定配合使用。

安装

SwiftValidators 支持 iOS 9.0+、Xcode 8 和 Swift 3.0

use_frameworks!

target 'MyProject' do
...
pod 'SwiftValidators'
...
end

它也可以通过 SPM 使用

import PackageDescription

let package = Package(
name: "MyProject",
targets: [],
dependencies: [
.Package(url: "https://github.com/gkaimakas/SwiftValidators.git",
majorVersion: 6)
]
)

操作流程

用法

验证通过使用Validator的apply函数完成。您可以手动创建Validator，或者使用Validator类中的静态函数中的已经存在的之一。

Validator的apply函数接收一个符合StringConvertible协议的可空值作为输入。默认情况下，String、NSString、Int、Float、Double和Bool都符合StringConvertible。

如果您使用的是静态Validator函数并且想指定当输入为nil时Validator的行为，请将nilResponse参数设置为true或false。默认情况下，nilResponse设置为false。

Validator.exactLength(3).apply("abc") //returns true

Validator.exactLength(3).apply(true) //returns false (the string representation of true is 'true')

Validator.exactLength(3).apply(nil) //returns false since `nilResponse` is set to false by default

Valuidator.exactLength(3, nilResponse: true).apply(nil) //returns true since we set nilResponse to true

有关如何调用每个验证器的更多示例，请参阅单元测试。

逻辑运算符

您可以使用逻辑运算符AND、OR和NOT（分别表示为 &&、|| 和 !）组合运算符。

let combinedANDValidator = Validator.required() && Validator.isTrue()

当值不为空且为“true”时，combinedANDValidator将返回true。

let combinedORValidator = Validator.isTrue() || Validators.isFalse()

当值为“true”或“false”时，combinedORValidator将返回true，否则返回false。

let reversedValidator = !Validator.isTrue()

当值等于“true”时，reversedValidator将返回false，对所有其他值返回true。

可用验证器

*FQDNOptions是一个用于isFQDN配置用途的类。可以通过这种方式实例化

FQDNOptions(requireTLD: Bool, allowUnderscores: Bool, allowTrailingDot: Bool)
