Asynchronous callback pattern for Afhttpclient

Source: Internet
Author: User

In the first version of iOS, the synchronous mode of HTTP is used in many places, causing the thread to block and develop a simple afhttpclient asynchronous callback mode.

Callback's protocol:

@protocol Myafnetworkingresponse <nsobject>

@required

-(voidnsstring*" ret Type: (nsstring*" strtype returndata: (nsobject*) retdata;

@end

Afhttpclient implementation classes for asynchronous communication:

@interface myafnetworkingclient: afhttpclient

@property nsurl* mserverurl;//http service address

@property ID<myafnetworkingresponse> delegate;//This is the most important, callback agent

class initialization function

-(ID) init;

-(ID) Initwithbaseurl: (nsurl *) URL;

/* Then a bunch of implemented functions */

.....

@end

Then in Viewcontroller:

@interface mainviewcontroller  () <   Myafnetworkingresponse>

@end

@implementation Mainviewcontroller

-(void) viewdidload {

[Super viewdidload];     

Initialization

     self.mafnetworkinghttpclient = [[myafnetworkingclient alloc] init";

self. Mafnetworkinghttpclient. Delegate = self;

}

-(void) Myhttpresponse: (nsstring*) ret Type: (nsstring*) strtype returndata: (nsobject *) retinfo{

    __weak   Mainviewcontroller* wself = self

     if  ([ Strtype isequaltostring:@" xxxx " ) {

         //a specific HTTP type, implementation processing

   } else < Span class= "S1" style= "margin:0px; padding:0px ">ifisequaltostring:@" xxxx "]) {

Implementation processing of a specific HTTP type

}

}

@end
