Question

我正在开发iOS应用程序，我正在使用Twilio SDK来管理通过设备进行的客户端调用。为了实现这一点，我使用的是我在Xcode中成功导入的hello monkey demo应用程序。初始设置后，我能够成功建立连接，但接收委托不再有效。我已经完成了完整的twilio文档，但没有成功。请尽快建议任何替代方案或解决方案。这是我的Hello Monkey示例项目代码

- (void)viewDidLoad
{

    NSLog(@"CLINT ID-----------------------     %@",name);

    //check out https://github.com/twilio/mobile-quickstart to get a server up quickly
    NSString *urlString = [NSString stringWithFormat:@"https://testdemo786.herokuapp.com/token?client=%@", name];
    NSURL *url = [NSURL URLWithString:urlString];
    NSError *error = nil;
    NSString *token = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];
    if (token == nil) {
        NSLog(@"Error retrieving token: %@", [error localizedDescription]);
    } else {
        _phone = [[TCDevice alloc] initWithCapabilityToken:token delegate:self];

    }
}

- (IBAction)dialButtonPressed:(id)sender
{
    NSString *to;
    if ([name isEqualToString:@"jenny"]) {
        to=@"client:tommy";
    }
    else
    {
        to=@"client:jenny";
    }


    to=@"4nmf5j";
    NSLog(@"TO---------------------%@",to);
    NSDictionary *params = @{@"To": to};

    _connection = [_phone connect:params delegate:nil];
}

- (IBAction)hangupButtonPressed:(id)sender
{
    [_connection disconnect];
}

- (void)device:(TCDevice *)device didReceiveIncomingConnection:(TCConnection *)connection
{
    NSLog(@"Incoming connection from: %@", [connection parameters][@"From"]);
    if (device.state == TCDeviceStateBusy) {
        [connection reject];
    } else {
        [connection accept];
        _connection = connection;
    }
}

-(void)connection:(TCConnection*)connection didFailWithError:  (NSError*)error{

    NSLog(@"Connection failed with error : %@", error);

}

-(void)connectionDidStartConnecting:(TCConnection*)connection{
    NSLog(@"connection started");
}

-(void)connectionDidDisconnect:(TCConnection*)connection{
    NSLog(@"connection disconnected");
}

-(void)connectionDidConnect:(TCConnection*)connection{
    NSLog(@"connected");
}

- (void)deviceDidStartListeningForIncomingConnections:  (TCDevice*)device
{
    NSLog(@"Device: %@ deviceDidStartListeningForIncomingConnections",   device);
}

- (void)device:(TCDevice *)device didStopListeningForIncomingConnections:(NSError *)error
{
    NSLog(@"Device: %@ didStopListeningForIncomingConnections: %@", device, error);
}

Answer 1

你是否将代表设置为自己？ _device = [[TCDevice alloc] initWithCapabilityToken:capabilityToken delegate:self];

Answer 2

Twilio福音传教士在这里。

从你所包含的代码中可以看出它有点难以辨别，这看起来对我来说是正确的。

以下是一些要检查的事项：

您是否在界面上添加了TCDeviceDelegate作为协议：
```
@interface FooViewController() <TCDeviceDelegate>
```
您确定将正确的客户名称传递给connect方法，并且从TwiML应用程序语音请求URL返回的TwiML是否正确包含该名称？

您可以通过查看Twilio Monitor来查看这一点，看看Twilio在检索或解析您的TwiML时是否记录了任何错误。你也可以检查你的Twilio call logs，看看Twilio说入站和出站呼叫的结果是什么。

希望有所帮助。
