无法在Swift 2项目中使用Objective-C Pod框架(“使用未声明类型的'SMPageControl'") [英] Can't use Objective-C Pod Framework in Swift 2 project ("Use of undeclared type 'SMPageControl'")

问题描述

我有一个在Xcode 7上运行的Swift 2项目.我正在使用CocoaPods(带有use_frameworks!的v0.38.2)，并且已经设法使这些框架正常工作:

I have a Swift 2 project running on Xcode 7. I'm using CocoaPods (v 0.38.2 with use_frameworks!) and have already managed to get those frameworks working:

• CryptoSwift
• Pluralize_swift

两个Pod都是用Swift编写的，因此到目前为止没有问题.它们发挥了魅力.

Both Pods are written in Swift, so no problems so far. They work as charm.

现在，我正在尝试使用用Objective-C编写的 SMPageControl .我已经看到可以在Swift 2中使用Obj-C Pods ，尝试了许多不同的组合，但我无法使其正常工作. SMPageControl类不会显示自动完成建议，很显然，当我尝试使用它时，编译器会抛出 Use of undeclared type 'SMPageControl' .

Now I'm trying to use SMPageControl which is written in Objective-C. I've seen it's possible to use Obj-C Pods with Swift 2, tried a lot of different combinations but I can't get it to work. SMPageControl class doesn't show on autocomplete suggestions, and obviously when I try to use it the compiler throws Use of undeclared type 'SMPageControl'.

到目前为止我所做的:

1. 将pod 'SMPageControl'添加到了我的Podfile
2. Ran pod install(我可以在Xcode项目树上看到Pod的源代码/框架)
3. 在构建阶段"中添加了SMPageControl.framework>将二进制文件与库链接"(就像我对其他可用框架所做的那样)
4. 创建了PROJECT_NAME-Bridging-Header.h并将其添加到项目的构建设置"中(我可以说它正在工作，因为在我正确导入SMPageControl之前它抛出了错误)
5. 在上面的文件中添加了#import <SMPageControl/SMPageControl.h>

1. Added pod 'SMPageControl' to my Podfile
2. Ran pod install (I can see the Pod source/framework on Xcode project tree)
3. Added SMPageControl.framework in Build Phases > Link Binary With Libraries (as I've done with the other frameworks that work)
4. Created PROJECT_NAME-Bridging-Header.h and added it on the project's Build Settings (I can tell it's working because it threw errors until I got to import SMPageControl correctly)
5. Added #import <SMPageControl/SMPageControl.h> to the file above

到目前为止，项目编译没有错误，但是我无法在Swift类中使用SMPageControl.在Swift文件中尝试了import SMPageControl，但是没有运气(它甚至不会自动完成).我知道有可能，但是我没有找到任何示例代码.

Up to here the project compiles without errors, but I can't get to use SMPageControl in my Swift classes. Tried import SMPageControl in the Swift file, but no luck (it doesn't even autocomplete). I understood it's possible, but I didn't find any example codes.

真的有可能吗?如果是这样，我想念什么?

Is it really possible? If so, what am I missing?

推荐答案

最后使它起作用，事实证明我实际上是缺少某些东西.

Finally got it to work, it turns out that I was actually missing something.

完成上述所有步骤，需要import Swift文件顶部的框架:

Along with all steps above, it's needed to import the framework at the top of the Swift file:

import SMPageControl

由于Xcode没有提供任何自动完成功能，所以我认为不可能做到这一点.添加import语句后，项目成功编译，并且可以使用SMPageControl()类.

Since Xcode was not providing any autocomplete I thought it wouldn't be possible to do that. Once I added the import statement, the project compiled successfully and I was able to use SMPageControl() class.
