将 Objective-C 框架连接到 Swift iOS 8 应用程序（解析框架）

Connect Objective-C framework to Swift iOS 8 app (Parse framework)

I am trying to use an Objective-C framework with the Swift programming language for iOS 8 development. This is a specific case of an import but the general problem is:

我正在尝试使用带有 Swift 编程语言的 Objective-C 框架进行 iOS 8 开发。这是导入的特定情况，但一般问题是：

How do you import an Objective-C framework into swift and get the import recognized?

你如何将一个 Objective-C 框架导入 swift 并让导入被识别？

I am trying to integrate the Parse framework into a swift application using the iOS 8 and Xcode 6 betas.

我正在尝试使用 iOS 8 和 Xcode 6 beta 将 Parse 框架集成到一个 swift 应用程序中。

Here is the technique for Parse framework integration in Objective-C:

I have downloaded the Parse framework as a compressed archive, extracted it, and imported it into Xcode 6 without any problems. Within my application it appears as a properly formatted framework under the name Parse.framework.

我已将 Parse 框架作为压缩档案下载、解压缩并将其导入 Xcode 6，没有任何问题。在我的应用程序中，它显示为名称为 Parse.framework 的格式正确的框架。

My current thought process is to modify the AppDelegate.swiftfile in the root directory of my project. Here is the current file without modifications (automatically generated by Xcode upon swift project creation):

我目前的思路是修改AppDelegate.swift我项目根目录下的文件。这是未经修改的当前文件（由 Xcode 在 swift 项目创建时自动生成）：

I have tried to import parse by adding the line import Parsebelow the line import UIKit. However, Xcode issues a warning that there is no such module found and the build fails.

我试图通过在 lineimport Parse下方添加 line 来导入 parse import UIKit。但是，Xcode 会发出警告，指出找不到此类模块并且构建失败。

I also tried creating a file ${PROJ_NAME_HERE}-Bridging-Header.hthat contains the Objective-C import of Parse using import <Parse/Parse.h>. This line doesn't throw an error but appears to ultimately make no difference.

我还尝试${PROJ_NAME_HERE}-Bridging-Header.h使用import <Parse/Parse.h>. 该行不会引发错误，但似乎最终没有任何区别。

A "Fool Proof" way of adding a bridging header is as follows:

添加桥接头的“傻瓜证明”方式如下：

If you have a Swiftproject, add a new Objective-C Fileto your project and Xcode will prompt if you want to configure your project with a bridging header. Press yes.

如果你有一个Swift项目，在你的项目中添加一个新的Objective-C 文件，Xcode 会提示你是否想用桥接头配置你的项目。按是。

If you have a Objective-Cproject, add a new Swift Fileto it and you will get the same prompt. Press yes.

如果您有一个Objective-C项目，向其中添加一个新的Swift 文件，您将得到相同的提示。按是。

After you get the bridging header, you can delete the file you just added if you want to.

获得桥接头后，您可以根据需要删除刚刚添加的文件。

After further research I found the solution and realized that I was just confused.

经过进一步研究，我找到了解决方案，并意识到我只是感到困惑。

The correct approach is as follows:

正确的做法如下：

• Import your Objective C framework by dragging and dropping the framework into an Xcode 6 Swift project.

• Create a new Objective C file in your project (File->New->File [Objective C for iOS]).

• Accept the prompt (agree) to create a bridging header file between Objective C and Swift.

• Delete your newly created Objective C file but retain the bridging header file ${YOURPROJ}-Bridging-Header.h.

• In the Bridging header file, import your framework using the standard Objective Cimport syntax (e.g. #import <Parse/Parse.h>).

• This relinquishes the need to perform an import Parsestatement in your AppDelegate.swiftfile. You can now write code that utilizes whatever framework as long as it is imported using the bridging header. It is available throughout your project's Swift files.

• 通过将框架拖放到 Xcode 6 Swift 项目中来导入您的 Objective C 框架。

• 在您的项目中创建一个新的 Objective C 文件（File->New->File [Objective C for iOS]）。

• 接受提示（同意）以在 Objective C 和 Swift 之间创建桥接头文件。

• 删除新创建的 Objective C 文件，但保留桥接头文件${YOURPROJ}-Bridging-Header.h。

• 在 Bridging 头文件中，使用标准的Objective C导入语法（例如#import <Parse/Parse.h>）导入您的框架。

• 这放弃了import Parse在AppDelegate.swift文件中执行语句的需要。您现在可以编写使用任何框架的代码，只要它是使用桥接头导入的。它在您项目的 Swift 文件中都可用。

Now, if you would like to test Parse integration in your project, you can type Parse.and use code completion to browse the framework and see that the code completion is indicative of a successful import.

现在，如果您想在您的项目中测试 Parse 集成，您可以键入Parse.并使用代码完成来浏览框架，并查看代码完成表示导入成功。

However, there is another caveat here that needs to be addressed when using a Bridging Header file. All dependencies of the framework need to be specified in the Bridging Header file as well. In the case of integrating Parse framework into a Swift application your Bridging Header file will look like this:

但是，在使用桥接头文件时，这里还有一个需要注意的问题。框架的所有依赖项也需要在桥接头文件中指定。如果将 Parse 框架集成到 Swift 应用程序中，您的桥接头文件将如下所示：

 #import <Foundation/Foundation.h>

 // Parse Dependencies
 #import <AudioToolbox/AudioToolbox.h>
 #import <CFNetwork/CFNetwork.h>
 #import <CoreGraphics/CoreGraphics.h>
 #import <CoreLocation/CoreLocation.h>
 #import <MobileCoreServices/MobileCoreServices.h>
 #import <QuartzCore/QuartzCore.h>
 #import <Security/Security.h>
 #import <StoreKit/StoreKit.h>
 #import <SystemConfiguration/SystemConfiguration.h>

 // Import parse framework
 #import <Parse/Parse.h>

Hope this helps.

希望这可以帮助。

The answer for my problem was different. I had the Framework Search Paths in my project's Build Settingsset to recursivewhen they should have been non-recursive.

我的问题的答案是不同的。我在项目的 Build Settings中将Framework Search Paths设置为recursive而不是 recursive。

In my case, my target has its Framework Search Paths set to $(inherited), which means to inherit the setting from my project.

就我而言，我的目标将其框架搜索路径设置为$(inherited)，这意味着从我的项目继承设置。

My project's Framework Search Paths only had one path, $PROJECT_DIR/../External/**(with the two asteriks meaning "search this folder recursively". My Parse.frameworkfile was located in the base level of the External folder.

我的项目的框架搜索路径只有一个路径，$PROJECT_DIR/../External/**（两个星号表示“递归搜索此文件夹”。我的Parse.framework文件位于外部文件夹的基本级别。

Changing the path from recursiveto non-recursivefixed things for me. Very strange...

为我改变从递归到非递归固定事物的路径。很奇怪...

New Parse framework version need some update.

新的 Parse 框架版本需要一些更新。

Such as You should insert libsqlite3.0.dylib in Library Binary With Libraries and update header file with #import and #import
