IOS: Socket-based third-party framework Cocoaasyncsocket usage

Cocoaasyncsocket is undoubtedly the most well-packaged socket library now: Support asynchronous TCP/UDP, support Gcd,objective-c interface encapsulation, as well as log tracking function, using this log tracking, programmers can easily debug.

The file is as follows:

If you want to turn on log debugging, it is easy to import the required DDASLLogger.h header files and create Ddasllogger simple interest objects.

The simple demo is as follows:

1. In the story version layout

2. In the ViewController.h file

 //  ViewController.h  //  Aysnsocket   #import  <uikit /uikit.h> #import   asyncsocket.h    @interface  Span style= "color: #000000;"    > viewcontroller:uiviewcontroller{Nsmutablearray  *_scokets; //     store variable array of clients     Asyncsocket *_sendsocket; //     send side     Asyncsocket *_recescoket; //  receive end     @end  

3. In the viewcontroller.m file

//VIEWCONTROLLER.M//Aysnsocket#import "ViewController.h"#import "AsyncSocket.h"@interfaceViewcontroller () @property (weak, nonatomic) Iboutlet Uitextview*Msgview, @property (weak, nonatomic) Iboutlet Uitextfield*Ipfield, @property (weak, nonatomic) Iboutlet Uitextfield*Sendfield;-(Ibaction) coneclicked: (UIButton *) sender;//connecting to a server-(Ibaction) sendclicked: (UIButton *) sender;//Send side Send message-(Ibaction) disconeclicked: (UIButton *) sender;//Disconnect Connection@end@implementationViewcontroller@synthesizeMsgview;@synthesizeIpfield;@synthesizeSendfield;- (void) viewdidload {[Super viewdidload]; //1.

The test is as follows:

(1) Open the computer's network settings, look at the IP and set the port to 8888

(2) Run the program and enter the IP and message in the demo

Start: Enter IP and messages, and then connect to the server

Successfully sent a successful connection to a successful server

To disconnect the server:

After disconnecting the server, the attempt to send the data is not sent and displayed on the Uitextview.
