在项目中，如果你使用的是SRWebSocket，需要采用wss的话，请看一下代码

NSURL *url = [[NSURL alloc] initWithString: [NSString stringWithFormat:@"wss://%@:%@",Socket_Host, Socket_Post]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];

NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"catchtoy.itcheku.com" ofType:@"cer"];

NSData *certData = [[NSData alloc] initWithContentsOfFile:cerPath];

CFDataRef certDataRef = (__bridge CFDataRef)certData;

SecCertificateRef certRef = SecCertificateCreateWithData(NULL, certDataRef);

id certificate = (__bridge id)certRef;

[request setSR_SSLPinnedCertificates:@[certificate]];

self.webSocket =  [[SRWebSocket alloc] initWithURLRequest:request];

如果是ws的接入

self.webSocket = [[SRWebSocket alloc]initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"ws://%@:%@",Socket_Host, Socket_Post]]];

ps:希望能帮到你..
