带有Swift的Google Objective-C API'GTL' [英] Google Objective-C API 'GTL' with Swift

问题描述

有没有人设法在Swift Project中使用Google Drive API（Objjective C）

https://developers.google.com/drive/ios/quickstart

我试过很多不同的方式，但无法编译

最接近的是在下面的链接中使用Rob的方法，并将#importGTLDrive.h添加到BridgingHeader 。这允许我创建一个GTLDrive，但不是Auth，因为我无法让Xcode关注No ARC标志。

Stackoverflow 11370752

解决方案

我最终设法通过以下方式来完成这项工作： Stack OverFlow 11370752

并添加一个bridging-header.h文件和

  #importGTLDrive.h
 #importGTMOAuth2ViewControllerTouch.h
  

为了节省时间，我将我的Objective-C包含到Google Quickstart中包含的示例的Swift翻译中。

Has anyone managed to use the Google Drive Api (Objjective C) in a Swift Project

https://developers.google.com/drive/ios/quickstart

I have tried a number of different ways but cannot get it to compile

The closest I came was using Rob's methodology in the link below and adding #import "GTLDrive.h" to the BridgingHeader. This allowed me to create a GTLDrive but not the Auth becauser I could not get Xcode to pay attention to the No ARC flags.

Stackoverflow 11370752

解决方案

I eventually managed to do this by following

Stack OverFlow 11370752

and adding a bridging-header.h file with

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

To save someone time I include my Objective-C to Swift Translation of the sample included in the Google Quickstart

    //        println("showWaitIndicator \(title)")
    var progressAlert = UIAlertView()

    progressAlert.show()
