当我编写 TCP...
socket = GCDAsyncSocket(delegate: self, delegateQueue: DispatchQueue.main)
那挺好的
但是当我编码UDP时......
udpSocket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)
错误说Type of expression is ambiguous with more context
我不知道我该如何解决。我搜索了“DispatchQueue”和 GCD 的定义,但仍然没有答案。
如果有人可以帮助我,我将不胜感激!!!
override func viewDidLoad(){
super.viewDidLoad()
udpSocket = GCDAsyncUdpSocket( delegate: self, delegateQueue: DispatchQueue.main)
}
func udpSocket(_ sock: GCDAsyncUdpSocket, didReceive data: Data, fromAddress address: Data, withFilterContext filterContext: Any?){
print("didReceiveData")
var host: NSString?
var port: UInt16 = 0
GCDAsyncUdpSocket.getHost(&host, port: &port, fromAddress: address)
showMessage("From IP: \(String(data: data, encoding: String.Encoding.utf8)!)")
print("From \(host!)")
print("incoming message: \(String(data: data, encoding: String.Encoding.utf8)!)")
}
func udpSocket(_ sock: GCDAsyncUdpSocket, didNotConnect error: Error?){
print("didNotConnect \(error!)")
}
func udpSocketDidClose(_ sock: GCDAsyncUdpSocket, withError error: Error?){
print("斷開連線error: \(error!)")
}
func udpSocket(_ sock: GCDAsyncUdpSocket, didNotSendDataWithTag tag: Int, dueToError error: Error?){
print("didNotSendDataWithTag")
}
func udpSocket(_ sock: GCDAsyncUdpSocket, didSendDataWithTag tag: Int){
print("didSendDataWithTag")
}
