我们项目中也使用wk_registerScheme注册 scheme，且注册有多个，有谁遇到过吗？

看下是不是这个原因 https://github.com/Yeatse/NSURLProtocol-WebKitSupport/issues/2

yuchuanfeng commented 5 years ago

恩，那个回答我之前也看过，把WKWebView 所使用的 WKProcessPool 设置成单例变量还是会有这个 crash，应该是其它原因吧

Elliotsomething commented 5 years ago

确实最终都是挂在进程通信sendMessages，之前苹果在上层修过一个bug√=https://trac.webkit.org/changeset/244246/webkit， 但是还是存在crash，有老哥知道怎么复现吗

wangjunhua1 commented 5 years ago

我也遇到的相同的crash 有解决方案吗

yuchuanfeng commented 5 years ago

@wangjunhua1 你能复现这个 crash 吗？
