在给定的ViewController上应用脚本API错误

Question

有没有人经历过这个API并想出了它？ 这是我第三次尝试按照本指南进行工作

我正在使用本指南的swift版本。

Google Apps Script Guide

，它总是给我同样的错误。

import UIKit 

class ViewController: UIViewController { 

    private let kKeychainItemName = "Google Apps Script Execution API" 
    private let kClientID = "493692471278-3mf6bo212flgjopl06hrjfeepphe70h4.apps.googleusercontent.com" 
    private let kScriptId = "Mj0RNm2ZtohFurieBLPwnxYAb4Jnnku4P" 
    // If modifying these scopes, delete your previously saved credentials by 
    // resetting the iOS simulator or uninstall the app. 
    private let scopes = ["https://www.googleapis.com/auth/drive"] 

    private let service = GTLService() // error Use of unresolved identifier 'GTLService' 


    let output = UITextView() 

    // When the view loads, create necessary subviews 
    // and initialize the Google Apps Script Execution API service 
    override func viewDidLoad() { 
     super.viewDidLoad() 

     output.frame = view.bounds 
     output.editable = false 
     output.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 20, right: 0) 
     output.autoresizingMask = UIViewAutoresizing.FlexibleHeight | 
      UIViewAutoresizing.FlexibleWidth 
     // error*** Binary operator '|' cannot be applied to two 'UIViewAutoresizing'  operands 


     view.addSubview(output);

      clientSecret: nil) { 
       service.authorizer = auth 
     } 

    } 

    // When the view appears, ensure that the Google Apps Script Execution API service is authorized 
    // and perform API calls 
    override func viewDidAppear(animated: Bool) { 
     if let authorizer = service.authorizer, 
      canAuth = authorizer.canAuthorize where canAuth { 
       callAppsScript()

       let details = apiError["details"] as! [[String: AnyObject]]

       output.text = errMessage 
      } else { 
       // The result provided by the API needs to be cast into the 
       // correct type, based upon what types the Apps Script function

       let response = object.JSON["response"] as! [String: AnyObject] 
       let folderSet = response["result"] as! [String: AnyObject] 
       if folderSet.count == 0 { 
        output.text = "No folders returned!\n" 
       } else { 
        var folderString = "Folders under your root folder:\n" 
        for (id, folder) in folderSet { 
         folderString += "\t\(folder) (\(id))\n" 
        } 
        output.text = folderString

} 

我觉得很难相信谷歌会作出指导，并使其不适用于当前版本的xcode。它甚至在他们的指南底部说，它已于2016年2月更新。

希望看看过去是否有人按照本指南运气。

是否有另一个这个谷歌API的快速指南？

预先感谢您。

Answer 1

1）看起来你没有得到头文件。你需要一个Bridging-Header.h。该步骤在快速入门中省略;请参阅Google云端硬盘快速入门以了解您需要采取的步骤。 2）你可以注释掉下面这行，似乎没有必要。

output.autoresizingMask = UIViewAutoresizing.FlexibleHeight | 
    UIViewAutoresizing.FlexibleWidth 

3）这些更改将解决编译问题。我发现在解决编译问题后，它不会链接并在手机上运行。 快速入门指南使用Xcode的“链接二进制库”链接GTL.framework与您的应用程序。我改为使用Cocoapods（https://cocoapods.org/pods/Google-API-Client）安装它，然后能够运行我的应用程序。
