Ios 更新为解析1.8.4 pod后Apple Mach-O链接器错误

在更新到最新的解析pod（1.8.4）后，我只有在为设备构建时才收到Apple Mac-O链接器错误。模拟器工作正常

请查看findObjectsInBackgroundWithBlock方法中的签名。将AnyObject更改为PFObject应该可以做到这一点

这是

ParseCrashReporting

库的一个问题。版本1.8.2没有此问题。在撰写本文时，该问题出现在1.8.3、1.8.4和1.8.5（当前版本）中

如果您可以从6.4升级到Xcode 7，则不会出现此问题

如果您仍然必须使用6.4，那么它似乎与在测试目标中包括Pods.xcconfig以及为设备构建时有关

具体而言，链接器错误包括：

它们都与

libParseCrashReportingLib.a

我在这里向Parse提交了一个问题，其中包括一个指向复制它的示例项目的链接。但是，步骤很简单：

在Xcode 6.4中，创建一个新的单视图iOS应用程序项目

创建一个

pod文件

，其中包括

ParseCrashReporting

：

 source 'https://github.com/CocoaPods/Specs.git'
 platform :ios, '8.0'
 pod 'ParseCrashReporting', '~> 1.8'

执行

pod安装

打开生成的

xcworkspace

，并将Pods.xcconfig添加到测试目标。

为设备构建

生成失败，测试目标出现上述链接器错误

---

我也看到了。具体来说，问题在于

ParseCrashReporting

而不是直接

Parse

。我测试了

parsecrashreporting1.8.2

（链接很好）。1.8.3和1.8.4似乎对我有这个问题。我提交了一个bug：是的，我对ParseCrashReporting（1.8.4）和ParseFacebookUtilsV4（1.8.4）@Gomines有问题，我不知道你在说什么

PFQuery.h

是其中的

-（void）findobjectsinbackgroundithblock:（PF_NULLABLE pfqueryarray resultblock）块已声明。没有定义
任何对象
符号。此外，至少在我的例子中，所有链接器错误都是
libParseCrashReportingLib.a
中的
duplicate symbol\u llvm.cmdline
（不是
Parse
（其中定义了
PFQuery
，而是在
ParseCrashReporting
库中）。
