从深层链接（具有应用程序特定方案的URL）启动我的iOS应用程序时，我在日志中收到此错误：
lsd[738] <Warning>: LaunchServices: application launch failed - timeout waiting for launch.
当应用程序正常启动时，没有错误。
没有关于超时根的其他日志。 我正在查看来自设备的日志。 这是完整的日志：

在看到相同的日志消息之前，我看到了8秒的延迟。

仅在应用尚未在后台启动应用时才会发生这种情况。我向Apple提交了一个错误。这个问题可以在iOS 9 beta 4中修复。不幸的是，旧版本的iOS将继续存在这个问题。
