Objective c react native和设置gmail api

我在设置gmail api时遇到问题。谁能告诉我哪里出了问题

说明：

Run the following command to download the library using git:

git clone --recursive https://github.com/google/google-api-objectivec-client.git

在命令行中，我导航到项目的根目录并运行该命令

Open Xcode and create a new workspace named "Quickstart".

Using File > Add Files to "Quickstart"..., add the following project to the workspace that you cloned in the previous step:
google-api-objectivec-client/Source/GTLCore.xcodeproj

我没有创建新的工作区，只是使用了现有的工作区。我单击了文件>将文件添加到“收件箱”，并添加了

GTLCore.xcodeproj

Create a new iOS > Application > Single View Application project named "QuickstartApp", with the organization "com.example". Set the Language to Objective-C, and when saving the project set the Add to and Group fields to "Quickstart".

因为我已经有一个项目，我没有做这一步

Add the following frameworks and libraries to the project's Build Phases > Link Binary with Libraries section:
GTL.framework (from GTLiOSCore target)

我点击了我的收件箱项目，选择了构建阶段并添加了GTL.framework

Change the following Build Settings:
Add the flag GTL_BUILT_AS_FRAMEWORK=1 to Preprocessor Macros.

我点击了我的收件箱项目，点击了构建设置，搜索了预处理器宏并添加了那行代码

Add the file google-api-objectivec-client/Source/OAuth2/Touch/GTMOAuth2ViewTouch.xib to the project's Supporting Files group.

我选择了inbox测试>支持文件，右键单击将文件添加到收件箱 但是，文件不在其所在的位置

/google-api-objectivec-client/Deps/gtm-oauth2/Source/Touch/GTMOAuth2ViewTouch.xib

将以下文件添加到QuickstartApp组：

google-api-objectivec-client/Source/Services/Gmail/Generated/GTLGmail_Sources.m

google-api-objectivec-client/Source/Services/Gmail/Generated/GTLGmail.h

我右键单击我的收件箱文件夹并选择“

将文件添加到收件箱”

”这两个文件都已添加到我的收件箱文件夹中

现在，请尝试编译，但出现一个错误：找不到“GTLObject.h”文件

该文件位于步骤3中添加的GTLCore.xcodeproj中。每次我添加其中一个文件时，它都会请求另一个文件

步骤4：我创建了自己的文件

gmail.h

#ifndef gmail_h
#define gmail_h
#import <UIKit/UIKit.h>

#import "GTL/GTMOAuth2ViewControllerTouch.h"
#import "GTLGmail.h"

@interface gmail : UIViewController
