Swift Validators Reactive Extensions🔶
ReactiveSwift 的 ValidatingProperty 是应用 SwiftValidators 的理想位置。 SwiftValidatorsReactiveExtensions 提供了一组扩展，使使用 ValidatingProperty 更容易。
内容
安装
SwiftValidatorsReactiveExtensions 可在 CocoaPods 上用于 iOS 9.0+、Xcode 8 和 Swift 3.0
pod 'SwiftValidatorsReactiveExtensions'
使用说明
使用方法
SwiftValidatorsReactiveExtensions 在 Validator 中提供了一个名为 reactive 的属性，它将每个可用的验证器映射到一个 ReactiveValidator。一个 ReactiveValidator 可以验证一个符合 StringConvertible 的值，结果将是 ValidatorOutput<StringConvertible?, ValidationError>。
ValidationError 是一个符合 Swift.Error 的枚举，为 SwiftValidators 中的所有可用验证器提供了一个案例，以及一个特殊案例 .notSpecified，用于在错误未指定时。
Validator.reactive
.isEmail().apply("[email protected]") // returns .valid
Validator.reactive
.isEmail().apply("abcd") // returns .invalid(.isEmail)有关如何调用每个验证器的更多示例，您可以查看 单元测试。
逻辑运算符
ReactiveValidator 允许将 combine 函数作为 static 函数和 instance 函数使用。该 combine 函数相当于逻辑与，意味着所有验证器必须为 .valid，组合验证器才为 .valid。
ReactiveValidator.combine(
Validator.reactive.isEmail(),
Validator.reactive.isLowercase()
) // variadic function
ReactiveValidator
.combine([
Validator.reactive.isEmail(),
Validator.reactive.isLowercase()
]) // array arguments
Validator.reactive
.isEmail()
.combine(with: Validator.reactive.isLowercase()) // instance function映射
SwiftValidatorsReactiveExtensions 提供了一个 map 函数，将 ReactiveValidator 的 ValidatorOutput<StringConvertible?, ValidationError> 结果映射到 ValidatingProperty 所期望的精确的验证器输出。
email = ValidatingProperty<String?, ValidationError>(nil, { (value: String?) -> ValidatorOutput<String?, ValidationError> in
return ReactiveValidator.combine([
Validator.reactive.required(),
Validator.reactive.minLength(5),
Validator.reactive.maxLength(32),
Validator.reactive.isEmail()
])
.apply(value)
.map() { $0 as? String }
})可用验证器
在 SwiftValidators 中可用的所有验证器。
