阅读更多关于 How do I read data using CocoaAsyncSocket?

问题 I have created a TCP Socket connection in my appDelegate didFinishLaunchingWithOptions method. That was the easy part, and I have successfully connected to my server. I am having great difficulty with reading the data from the server in my View. I have been looking through tutorials on how to appropriately (step by step) read data using CocoaAsyncSocket , but I haven't come across anything useful. This is my code from my appDelegate: -(BOOL)application:(UIApplication *)application

问题 I have been using CocoaAsyncSocket to send data to our server without SSL. Now the server side has implemented SSL/TLS with client authentication. TO implement this in our app I was given the following three files: ca-chain.cert.pem client-test.cert.pem client-test.key.pem I converted the files to iOS readable formats as below: ca-chain.cert.pem to ca-cert.cer client-test.cert.pem to client_cert.cer client-test.key.pem to client_key.p12 I have got it working till SSL. But having trouble with

So here's the issue: The stream isn't writing at the right time and is unable to get a response from my server. I know I'm writing the right data, because when I stop the build, it writes to the server and the server is happy. I'm confused to as why this isn't happening at the right time. I'm using GCDAsyncSocket to read/write to the socket I've made a separate class to handle all networking, here's my code: -(id)init{ self = [super init]; if (self) { asyncSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()]; NSError *error = nil; if (![asyncSocket

问题 In first approach I create client-server app ,based on sampleProject , which send some data to server. Legend: sender address = reciver ip port = reciver port reciver address = null since he is listening port = in my case 55555 Working code skipping error checking is intentional only for public reasons Sender -(id*)initForSender:(NSString*)address port:(int)port { self = [super init]; if (self) { _port = port; _address = address; tag = 0; _udpSocket = [[GCDAsyncUdpSocket alloc]

Can you call a javascript function from native code (not in a callback) using PhoneGap and iOS?

阅读更多关于 Can you call a javascript function from native code (not in a callback) using PhoneGap and iOS?

I'm hoping to be able to use PhoneGap for my app. I will have to build a custom protocol/plugin so that I can call Native methods from the Javascript. I know you can call a success function in the Javascript when the native code returns. What I need to be able to do is call a javascript function from the native code. Basically the app will connect to an OSX companion app over local network and when the OSX app send data to the iOS app it is processed in an Objective C method, I need to be able to send the result into the PhoneGap/javascript and do something with it in the WebView. Is this

Swift: Receive UDP with GCDAsyncUdpSocket

阅读更多关于 Swift: Receive UDP with GCDAsyncUdpSocket

BACKGROUND: I want to be able to send and receive UDP packets between my iOS app and a server. The server echoes back every incoming message to the client the app. The server is tested and confirmed working . I have a StartViewController which starting up two classes that implements GCDAsyncUdpSocketDelegate, one for sending and one for receiving. The "sending socket" is working, the server receives the messages. PROBLEM: The app never get the incoming message back after it been sent. Something with the listening socket setup is probably wrong since didReceiveData never get called. Have I done
