Failed Uploads Fix

Lloyd and I think we figured out the reason why uploads are failing. In TripManager.m there is a switch statement which runs through a bunch of server responses and if it does not receive any of them defaults to a kServerError message which prints "Upload Failed. Try again later." We just need to rewrite the switch statement to cover all scenarios of server responses because uploads are going through but the server is not passing a message back that the switch statement can interpret so it is defaulting to a failed upload.

\- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response

{

    // this method is called when the server has determined that it

    // has enough information to create the NSURLResponse

    NSLog(@"didReceiveResponse: %@", response);


```

NSHTTPURLResponse *httpResponse = nil;

if ( [response isKindOfClass:[NSHTTPURLResponse class]] &&

    ( httpResponse = (NSHTTPURLResponse*)response ) )

{

    BOOL success = NO;

    NSString *title   = nil;

    NSString *message = nil;

    switch ( [httpResponse statusCode] )

    {

        case 200:

        case 201:

            success = YES;

            title   = kSuccessTitle;

            message = kSaveSuccess;

            break;

        case 202:

            success = YES;

            title   = kSuccessTitle;

            message = kSaveAccepted;

            break;

        case 500:

        default:

            title = @"Internal Server Error";

            //message = [NSString stringWithFormat:@"%d", [httpResponse statusCode]];

            message = kServerError;

    }

    NSLog(@"%@: %@", title, message);

    //

    // DEBUG

    NSLog(@"+++++++DEBUG didReceiveResponse %@: %@", [response URL],[(NSHTTPURLResponse*)response allHeaderFields]);

    if ( success )

    {

        [note setUploaded:[NSDate date]];

        NSError *error;

        if (![managedObjectContext save:&error]) {

            // Handle the error.

            NSLog(@"TripManager setUploaded error %@, %@", error, [error localizedDescription]);

        }

        [uploadingView loadingComplete:kSuccessTitle delayInterval:.7];

    } else {

        [uploadingView loadingComplete:kServerError delayInterval:1.5];

    }

}

// it can be called multiple times, for example in the case of a

// redirect, so each time we reset the data.

// receivedData is declared as a method instance elsewhere

[receivedDataNoted setLength:0];

```

}

从 TripManager.m 中的 connection:didReceiveResponse: 开始，检查 NSHTTPURLResponse 的状态码如何映射到上传结果。将已处理的状态与应用使用的服务器响应进行比较，然后验证成功的上传不再显示 kServerError 消息。
