Ios 将ObjC项目与SalesForce SDK桥接会由于无法在SF SDK中找到类别而导致崩溃

我有一个名为Core.proj的iOS项目，包括SalesForce SDK，它是用Objective-C编写的。该项目使用SF SDK并将二进制文件链接到SF库。它做了很多事情来帮助我管理SF的实现。它包含在我的所有其他Obj-C项目中，并且在其中工作得非常好

这是我第一次在Swift（2.1）中使用这个项目。我正在使用iOS9和Xcode 7.1.1。我在Swift项目中添加了Core.xcodeproj。然后我创建了一个ObjC文件。然后，Xcode询问我是否要创建桥接头。我愿意。我已经创建了一个名为Swift bridge header.h的桥接头。这使我能够通过桥接头访问Core.xcodeproj中的文件。例如，我可以从桥接头访问自己版本的Salesforce Authentication Manager

在我的AppDelegate中，我现在想启动OAuth（我在这里保持这个最小值）：

完全公开：您在这里看到的每个块都将SFOAuthInfo对象作为参数。为了让斯威夫特阅读这个区块，我必须将SFOAuthInfo.h添加到复制文件中

现在，所有这些都可以编译，但当我点击登录并执行上述代码时，会出现以下错误：

SF SDK有一个名为UIDevice+SFHardware.h的类别。在这个类别中有一个名为“macaddress”的方法。因此，很明显，它没有正确解读这一类别。但是为什么呢？从堆栈跟踪中可以看到，它正在正确读取SF SDK中的其他文件

我尝试了很多方法来让它发挥作用。例如，这个：但是使用UIDevice+SFHardware.h。我试过这个：。我再次完全重建了项目以检查我的工作

我不需要将这个文件添加到我的网桥中，因为这个UIDevice+SFHardware.h只能从位于ObjC项目中的SF SDK访问

不过我一定是做错了什么。任何帮助都将不胜感激

我刚刚讨论了这个问题

在项目>生成设置>其他链接器标志中添加： -ObjC -全负荷

---

我的SalesforceSDK在我的Pod项目中。如果您也这样做，请在SalesforceMobileSDK iOS项目中设置这些标志。如果不是，那么无论Salesforce SDK在哪里编译。

事实证明，这是多种因素的组合。首先，我在Swift项目和ObjC项目中都缺少-ObjC链接器标志。感谢DarthVadar123451指出这一点。但我也意识到我缺少了两个库：libz.dylib和libxml2.dylib。一旦添加，一切都起作用了。我希望这能帮助任何遇到同样问题的人
