Twilio iOS 无法识别的选择器已发送至 Class

Question

我刚开始使用 Twilio，我希望有人可以帮助我调试我的应用程序。

我正在调用以获取功能令牌，并且返回正常。我将它打印在控制台中进行检查，然后当我调用 initWithCapabilityToken 时它会出现，这是出现问题的地方，我无法弄清楚。

这是我的代码...

[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:
 ^(NSURLResponse *response, NSData *data, NSError *error){
     // Log Any Reply
     if ([data length] >0 && error == nil) {
         NSData *jsonData = data;

         // Deserialize JSON into Dictionary
         error = nil;
         id jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData
                                                         options:NSJSONReadingAllowFragments
                                                           error:&error ];
         if (jsonObject != nil && error == nil) {
             NSLog(@"Successfully deserialized JSON response...");

             if ([jsonObject isKindOfClass:[NSDictionary class]]) {
                 NSDictionary *deserializedDictionary = (NSDictionary *)jsonObject;
                 NSLog(@"Deserialized JSON Dictionary = %@", deserializedDictionary);

                 NSString *token = [deserializedDictionary objectForKey:@"token"];
                 if (token == nil) {
                     NSLog(@"Error retrieving token");
                 } else {
                     NSLog(@"Token: %@", token);
                     // Setup TCDevice
                     _phone = [[TCDevice alloc] initWithCapabilityToken:token delegate:self];
                 }
             }
         } else if (error != nil){
             NSLog(@"An error happened while de-serializing the JSON data.");
         }
     }else if ([data length] == 0 && error == nil){
         NSLog(@"Nothing was downloaded.");
     }else if (error != nil){
         NSLog(@"Error happened = %@", error);
     }
 }];

这是我在记录令牌后立即得到的...

谢谢

Answer 1

您在某处调用不存在的 stringWithPJStr 函数（选择器）。

Answer 2

阅读所有 Twilios 文档后，我发现我遗漏了一件事。我必须将 -ObjC 添加到其他链接器标志，这解决了我的问题。

Answer 3

将此行添加到其他链接器标志：

-ObjC
-lTwilioClient
-lcrypto
-lssl

它只对我有用，上面的 C 添加结尾 (-ObjC)
