从深度链接 : lsd[738] : LaunchServices: application launch failed - timeout waiting for launch 启动时出现 iOS 错误

Question

从深层链接(具有应用特定方案的 URL)启动我的 iOS 应用时，我在日志中收到此错误:

lsd[738] <Warning>: LaunchServices: application launch failed - timeout waiting for launch.

应用正常启动时，没有报错。

没有关于超时根源的其他日志。我正在查看来自设备的日志。这是完整的日志:

Answer 1

在看到相同的日志消息之前，我看到了 8 秒的延迟。

Mar 26 18:03:48 iPod **lsd[738] <Warning>: LaunchServices: application launch failed - timeout waiting for launch.**

只有当应用程序尚未在后台时启动应用程序时才会发生这种情况。我向 Apple 提交了一个错误。这个问题应该在 iOS 9 beta 4 中得到修复。不幸的是，旧版本的 iOS 将继续存在这个问题。
