CloverKit

說(shuō)明

該項(xiàng)目為 Target-Action 組件化方案的現(xiàn)代化實(shí)現(xiàn)。

工具

thrift、swift-gen

使用

服務(wù)定義

定義 thrift 文件：InvoiceService.thrift

struct Invoice {
    0: required i32 id
    1: required string name
    2: required string email
}

service InvoiceService {
    Invoice loadInvoice(1: required string userID)
}

生成代碼

終端執(zhí)行如下命令

./thrift -c CK  -i ./Services/InvoiceService.thrift --client_out ../CKServices
./thrift -s CKS -i ./Services/InvoiceService.thrift --server_out ../CKInvoiceModule

        self.name = name

服務(wù)實(shí)現(xiàn)

extension CKInvoiceService {
    
    func loadInvoice(userID: String, completion: @escaping (Swift.Result<CKSInvoice, Error>) -> Void) -> Bool {
        let invoiceVC = CKInvoiceViewController.makeViewController(ensureAction: { vc, invoice in
            vc.dismiss(animated: true, completion: {
                completion(.success(invoice))
            })
        }, cancelAction: { vc in
            vc.dismiss(animated: true, completion: {
                completion(.failure(NSError(domain: "", code: 0, userInfo: nil)))
            })
        })
        UIViewController.current.present(UINavigationController(rootViewController: invoiceVC), animated: true, completion: nil)
        return true

服務(wù)調(diào)用

_ = InvoiceService.loadInvoice(userID: "1234567890") { result in
    switch result {
    case .success(let invoice):
        let alert = UIAlertController(title: "Success", message: "\(invoice.name)\n\(invoice.email)", preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
        UIViewController.current.present(alert, animated: true, completion: nil)
    case .failure(let error):
        let alert = UIAlertController(title: "Failure", message: error.localizedDescription, preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
        UIViewController.current.present(alert, animated: true, completion: nil)
    }
}.invoke()
