Google Objective-C API 'GTL' с Swift

Ответ 1

В итоге мне удалось сделать это, следуя

Стек OverFlow 11370752

и добавив файл с мостом-header.h с

#import "GTLDrive.h"
#import "GTMOAuth2ViewControllerTouch.h"

Чтобы сэкономить время, я включаю свой Objective-C в Swift Перевод примера, включенного в Quickstart Google

Быстрый запуск IOS для Google Диска

import UIKit
import MobileCoreServices

    progressAlert.show()

    let activityView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.White)

Лучше использовать Pod для добавления Google Objective-C API 'GTL' в проект iPhone ссылку После этого вы можете реализовать ответ @Ryan Heitner

Не совсем ответ на этот вопрос, но в этом репо я обратился к Google Forms из приложения iOS, не используя API Google. https://github.com/goktugyil/QorumLogs

Вот учебник по настройке: https://github.com/goktugyil/QorumLogs/blob/master/Log%20To%20GoogleDocs.md

Вот код для этого:

private static var googleFormLink: String!
private static var googleFormAppVersionField: String!
private static var googleFormUserInfoField: String!
private static var googleFormMethodInfoField: String!
private static var googleFormErrorTextField: String!

/// Setup Google Form links
static func setupOnlineLogs(#formLink: String, versionField: String, userInfoField: String, methodInfoField: String, textField: String) {
    googleFormLink = formLink
    googleFormAppVersionField = versionField
    googleFormUserInfoField = userInfoField
    googleFormMethodInfoField = methodInfoField
    googleFormErrorTextField = textField
}

private static func sendError(#text: String) {
    var url = NSURL(string: googleFormLink)
    var postData = googleFormAppVersionField + "=" + text
    postData += "&" + googleFormUserInfoField + "=" + "anothertext"        
    postData += "&" + googleFormMethodInfoField + "=" + "anothertext" 
    postData += "&" + googleFormErrorTextField + "=" + "anothertext" 

    var request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"
    request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
    var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)

}
