Question

在使用gdb启动我的应用程序时，我遇到了奇怪的错误：

unable to read unknown load command 0x22

整个跟踪看起来像这样：

我已尝试过各种可用的分析工具，无法找到任何内存泄漏或任何可能导致这些未知错误的内容。

帮助？

这个问题有两个部分修复。

确保您在Copy Frameworks构建阶段进行Sparkle复制。

其次，在Copy Frameworks之后将以下脚本添加为buildphase有助于修复某些计算机上的加载路径。

install_name_tool -change "@loader_path/../Frameworks/Sparkle.framework/Versions/A/Sparkle" "@executable_path/../Frameworks/Sparkle.framework/Versions/A/Sparkle" "$BUILT_PRODUCTS_DIR/$EXECUTABLE_PATH"

下面是我的项目中这个buildphase的截图。
