简单地初始化一个事件源，然后订阅以接收事件
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:@"http://127.0.0.1:8888/"];
MSServerSentEventsSource *serverSentEventsSource = [[MSServerSentEventsSource alloc] initWithRequest:request receive:^(MSServerSentEvent *event) {
NSLog(@"received:%@",event);
}
completion:^{
NSLog(@"closed");
}
failure:^(NSError *error) {
NSLog(@"error:%@",error);
}];
[serverSentEventsSource addListenerForEvent:@"open" usingBlock:^(MSServerSentEvent *event) {
NSLog(@"received open event");
}];
[serverSentEventsSource addListenerForEvent:@"message" usingBlock:^(MSServerSentEvent *event) {
NSLog(@"received message event");
}];MSServerSentEvents 通过 CocoaPods 提供。要安装它，只需将以下行添加到您的 Podfile:
