我想在 XCode 控制台中禁用记录动态加载程序事件 (dyld) 的打印。我找到了解决方案here。 但我找不到记录 Dyld API 使用情况 and 日志库加载XCode 11的产品方案诊断中的选项。请帮我找到它们。

PS：如果Xcode11中有一个新的禁用日志的过程，请告诉我。

答案：下面的答案中建议了此分步解决方案。我只是附上这张图片以便更好地理解。

动态装载机

• 事件环境变量

有人会说你可以设置环境变量，例如DYLD_PRINT_APIS=0, DYLD_PRINT_APIS=false, DYLD_PRINT_APIS=no，...但这样不行。检查源代码:

else if ( strcmp(key, "DYLD_PRINT_APIS") == 0 ) {
    gLogAPIs = true;
}

换句话说gLogAPIs is true当变量存在时。您可以将其设置为任何值，将其保留为空，如果变量存在，它将始终启用。

Xcode方案

UI for this setting is gone in the Xcode 11, but it can still be in the scheme file. Let's say that you have a simple project Foo. The scheme is located at Foo/Foo.xcodeproj/xcshareddata/xcschemes/Foo.xcscheme¹⁾. It's a XML file. Quit Xcode and open this file in any editor and search for the LaunchAction element.

将有：

• LaunchAction element attribute like enableAddressSanitizer = "YES"²⁾ or
• DYLD_...环境变量设置。

只要删除这个属性/环境变量就可以了。

¹⁾ The exact path can vary, because it the scheme can be included in the workspace, project, ...

²⁾ I don't have a previous version (10) of Xcode installed, can't check for the exact name, but it should be there and it will be obvious which one it is. This one, I used, is for the Address Sanitizer checkbox. If you find the exact name, let me know and I will update this answer or answer it yourself and I'll delete this one.

Update

上述说明帮助 OP 找到准确的 XML 元素名称。必须删除：

• LaunchAction/AdditionalOptions/AdditionalOption元素
• 哪里的key或者是DYLD_PRINT_LIBRARIES and/or DYLD_PRINT_APIS
