让 MobileVLCKit 通过 Cocoapods 工作

Question

一段时间以来，我一直在努力让 VLC 在我的 iOS 应用中运行。使用 Cocoapods，MobileVLCKit 被导入到我的项目中。当我现在运行该应用程序时，它可以毫无问题地编译。但是，当我包含 MobileVLCKit 中的任何内容（MobileVLCKit.h、VLCMediaPlayer.h）时，应用程序崩溃，告诉我找不到符号。 这是崩溃：

当我通过可可豆荚安装 VLC 时，我收到了这个警告：

The `iOSCamApp [Release]` target overrides the `OTHER_LDFLAGS` build setting defined in `../Pods/Target Support Files/Pods-iOSCamApp/Pods-iOSCamApp.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

当我添加 $(inherited) 标志并尝试构建时，出现以下崩溃：

有人知道该怎么做吗？我已经尝试了很多东西，但似乎没有任何帮助。自动完成能够读取 VLC 的内容并在 Xcode 中为我自动完成，所以框架应该没问题。

Answer 1

架构 arm64 的未定义符号：

这似乎是问题所在。您正在为模拟器编译，显然 MobileVLCKit 没有为它编译。 ld 是抱怨此问题的链接器。你试过在设备上运行它吗？

检查您的项目和 MobileVLCKit 在哪些架构上处于活动状态。
