GCDAsyncUdpSocket无法绑定iOS模拟器上的端口 [英] GCDAsyncUdpSocket cannot bind port on iOS simulator
问题描述
我正在通过UDP发送消息.但是，我一直被困在绑定端口"的问题上.
当我第一次在iOS模拟器上构建项目时，没有任何奇怪的事情发生.一切都很好.
但是当我第二次建立项目时.当应用尝试绑定端口时，我从终端收到一条错误消息.
消息如下:错误域= NSPOSIXErrorDomain代码= 48地址已在使用中" UserInfo = 0x767c830 {NSLocalizedFailureReason = bind()函数中的错误，NSLocalizedDescription =地址已在使用中}"
让我感到困惑的是，当我在iPad上运行我的应用程序时，没有出现该错误.
我猜可能是因为我没有关闭插座.但是为什么它可以在iPad上正常运行?
希望有人可以解决这个问题.谢谢！
当前GDAAsyncUdpSocket头未设置SO_REUSEPORT(它只是设置了ADDRESS，对于TCP来说已经足够了).
我刚刚弹出了一个快速修复方法:

https://github.com/dirkx/CocoaAsyncSocket ，它也应该固定在上游: https://github.com/robbiehanson/CocoaAsyncSocket/pull/159 谢谢 Dw. I'm working on sending message through UDP. However, I've been trapped in the problem about 'binding port'. When I built the project on iOS simulator first time, nothing strange happened. Everything was fine. But when I built the project second time. I got an error message from terminal when the app tried to bind port. The message goes like this "Error Domain=NSPOSIXErrorDomain Code=48 "Address already in use" UserInfo=0x767c830 {NSLocalizedFailureReason=Error in bind() function, NSLocalizedDescription=Address already in use}" What's confuses me is that the error didn't appear when I run my app on iPad. I guess that maybe it is for the reason that I didn't close the socket. But why it goes correctly on iPad？ Hope someone could solve this. Thx! Current head of GDAAsyncUdpSocket does not (also) set SO_REUSEPORT (it just does ADDRESS, which is quite enough for TCP). I just popped in a quick fix: https://github.com/dirkx/CocoaAsyncSocket/commit/5ec8c83d59ecb754824f706198eb62e29961c1be https://github.com/dirkx/CocoaAsyncSocket and it should get fixed upstream too: https://github.com/robbiehanson/CocoaAsyncSocket/pull/159 Thanks, Dw. 这篇关于GCDAsyncUdpSocket无法绑定iOS模拟器上的端口的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
