ios - 如何使用 SRWebsocket 检查网络套接字是否处于事件状态

Question

我正在使用 SRWebsocket 进行套接字连接。现在，只要应用程序进入前台，我就会调用套接字打开功能，但我不想那样做。我需要先检查连接是否处于事件状态，然后才打开 websocket。有什么办法吗？

- (void)connectWebSocket {


if( self.readyState == SR_OPEN){

    NSLog(@"CONNECT%u ",self.readyState);
} else {

    NSLog(@"CLOSED %u",self.readyState);

}





[[IXDataBaseManager sharedNetworkDataManager] deleteOldPolls];


NSString *urlString =@"wss://m.hol.com/testing/api/ws/"; 



if( self.webSocket ) {
    [self.webSocket close];
    self.webSocket.delegate = nil;
    self.webSocket=nil;
}
self.webSocket = [[SRWebSocket alloc] initWithURLRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]] protocols:@[@"hol-json"]];
self.webSocket.delegate = self;
[self.webSocket open];
NSLog(@"CONNECTOPN%u ",self.readyState);

}

self.readyState 总是返回“0”

这个示例代码可能对您有帮助:

- (void)openSocket {
    if (_webSocket.readyState == SR_CLOSED)
    {
        // _websocket is closed. Open your web socket again
        [_webSocket open];
    } else {
        // _websocket is not closed. check the readyState and perform your task accordingly
    }
}

- (void)forceOpenSocket {
    _webSocket.delegate = nil;
    [_webSocket close];

    _webSocket = [[SRWebSocket alloc] initWithURLRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"Input Url"]]];
    _webSocket.delegate = self;

    // Opening Connection ...
    [_webSocket open];
}
