iOS Development--afnetworking Framework use detailed

Afnetworking is a delightful networking library for IOS and Mac OS x.it ' s built on top of the Foundation URL Loading syste M, extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, and Feature-rich APIs that is a joy to use.

Afnetworking is a popular network class library based on iOS and Mac OS x. Built on top of the framework of the URL loading system, it builds on the cocoa, extending a powerful high-level network abstraction. It is enjoyable to have a well-designed modular architecture and rich functionality.

How to use:
1.GET Request

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];[manager GET:@"http://example.com/resources.json" parameters:nilid responseObject) {    NSLog(@"JSON: %@"NSError *error) {    NSLog(@"Error: %@", error);}];

2.POST Request

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];NSDictionary *parameters = @{@"foo": @"bar"};[manager POST:@"http://example.com/resources.json"id responseObject) {    NSLog(@"JSON: %@"NSError *error) {    NSLog(@"Error: %@", error);}];

3.POST multi-part Request

Afhttprequestoperationmanager *manager = [Afhttprequestoperationmanager manager];nsdictionary*parameters = @{@"foo": @"Bar"};Nsurl*filepath = [Nsurlfileurlwithpath:@"File://path/to/image.png"]; [Manager post:@"Http://example.com/resources.json"Parameters:parameters constructingbodywithblock:^ (ID<AFMultipartFormData> formData) {[FormData Appendpartwithfileurl:filepath name:@"Image"ErrorNil];} success:^ (Afhttprequestoperation *operation,IDResponseobject) {NSLog(@"Success:%@", responseobject);} failure:^ (Afhttprequestoperation *operation,Nserror*error) {NSLog(@"Error:%@", error);}];

4. Create a download task

Nsurlsessionconfiguration *configuration = [Nsurlsessionconfiguration defaultsessionconfiguration]; Afurlsessionmanager *manager = [[Afurlsessionmanager alloc] initwithsessionconfiguration:configuration];Nsurl*url = [Nsurlurlwithstring:@"Http://example.com/download.zip"];nsurlrequest*request = [nsurlrequestRequestwithurl:url]; Nsurlsessiondownloadtask *downloadtask = [Manager downloadtaskwithrequest:request Progress:Nildestination:^Nsurl*(Nsurl*targetpath, Nsurlresponse *response) {Nsurl*documentsdirectoryurl = [[NsfilemanagerDefaultmanager] Urlfordirectory:nsdocumentdirectory indomain:nsuserdomainmask appropriateforurl:NilCreateNOErrorNil];return[Documentsdirectoryurl urlbyappendingpathcomponent:[response suggestedfilename];} completionhandler:^ (Nsurlresponse *response,Nsurl*filepath,Nserror*error) {NSLog(@"File downloaded to:%@", FilePath);}]; [Downloadtask resume];

5. Create an upload task

Nsurlsessionconfiguration *configuration = [Nsurlsessionconfiguration defaultsessionconfiguration]; Afurlsessionmanager *manager = [[Afurlsessionmanager alloc] initwithsessionconfiguration:configuration];Nsurl*url = [Nsurlurlwithstring:@"Http://example.com/upload"];nsurlrequest*request = [nsurlrequestRequestwithurl:url];Nsurl*filepath = [Nsurlfileurlwithpath:@"File://path/to/image.png"]; Nsurlsessionuploadtask *uploadtask = [Manager uploadtaskwithrequest:request Fromfile:filepath Progress:Nilcompletionhandler:^ (Nsurlresponse *response,IDResponseobject,Nserror*error) {if(Error) {NSLog(@"Error:%@", error); }Else{NSLog(@"Success:%@%@", response, Responseobject); }}]; [Uploadtask resume];

6. Create an upload file task and show progress

Nsmutableurlrequest *request = [[Afhttprequestserializer serializer] multipartformrequestwithmethod:@"POST"urlstring:@"Http://example.com/upload"ParametersNilconstructingbodywithblock:^ (ID<AFMultipartFormData> formData) {[FormData appendpartwithfileurl:[Nsurlfileurlwithpath:@"File://path/to/image.jpg"] name:@"File"filename:@"Filename.jpg"mimetype:@"Image/jpeg"ErrorNil]; } Error:Nil]; Afurlsessionmanager *manager = [[Afurlsessionmanager alloc] Initwithsessionconfiguration:[nsurlsessionconfiguration Defaultsessionconfiguration]]; Nsprogress *progress =Nil; Nsurlsessionuploadtask *uploadtask = [Manager uploadtaskwithstreamedrequest:request progress:&progress completionhandler:^ (Nsurlresponse *response,IDResponseobject,Nserror*error) {if(Error) {NSLog(@"Error:%@", error); }Else{NSLog(@"%@ %@", response, Responseobject); }}]; [Uploadtask resume];

7. Create a Data Flow task

Nsurlsessionconfiguration *configuration = [Nsurlsessionconfiguration defaultsessionconfiguration]; Afurlsessionmanager *manager = [[Afurlsessionmanager alloc] initwithsessionconfiguration:configuration];Nsurl*url = [Nsurlurlwithstring:@"Http://example.com/upload"];nsurlrequest*request = [nsurlrequestRequestwithurl:url]; Nsurlsessiondatatask *datatask = [Manager datataskwithrequest:request completionhandler:^ (NSURLResponse *response,IDResponseobject,Nserror*error) {if(Error) {NSLog(@"Error:%@", error); }Else{NSLog(@"%@ %@", response, Responseobject); }}]; [Datatask resume];

8. Get Network status

[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));}];[[AFNetworkReachabilityManager sharedManager] startMonitoring];

9.HTTP Manager reachability (Accessibility)

Nsurl*baseurl = [Nsurlurlwithstring:@"http://example.com/"]; Afhttprequestoperationmanager *manager = [[Afhttprequestoperationmanager alloc] initwithbaseurl:baseurl]; Nsoperationqueue *operationqueue = Manager. Operationqueue; [Manager. Reachabilitymanagersetreachabilitystatuschangeblock:^ (afnetworkreachabilitystatus status) {Switch(status) { CaseAfnetworkreachabilitystatusreachableviawwan: CaseAfnetworkreachabilitystatusreachableviawifi: [Operationqueue setsuspended:NO]; Break; CaseAfnetworkreachabilitystatusnotreachable:default: [Operationqueue setsuspended:YES]; Break; }}]; [Manager. ReachabilitymanagerStartmonitoring];

10.AFHTTPRequestOperation GET Request (Afhttprequestoperationmanager is usually the best way to go, but afhttprequestopersion can also be used alone)

Nsurl*url = [Nsurlurlwithstring:@"Http://example.com/resources/123.json"];nsurlrequest*request = [nsurlrequestRequestwithurl:url]; Afhttprequestoperation *op = [[Afhttprequestoperation alloc] Initwithrequest:request];op. Responseserializer= [Afjsonresponseserializer serializer]; [Op setcompletionblockwithsuccess:^ (Afhttprequestoperation *operation,IDResponseobject) {NSLog(@"JSON:%@", responseobject);} failure:^ (Afhttprequestoperation *operation,Nserror*error) {NSLog(@"Error:%@", error);}]; [[Nsoperationqueue Mainqueue] addoperation:op];

11.Batch of Operations

Nsmutablearray*mutableoperations = [NsmutablearrayArray]; for(Nsurl*fileurl in Filestoupload) {nsurlrequest*request = [[Afhttprequestserializer serializer] multipartformrequestwithmethod:@"POST"urlstring:@"Http://example.com/upload"ParametersNilconstructingbodywithblock:^ (ID<AFMultipartFormData> formData) {[FormData appendpartwithfileurl:fileurl name:@"images[]"ErrorNil];    }];    Afhttprequestoperation *operation = [[Afhttprequestoperation alloc] initwithrequest:request]; [Mutableoperations addobject:operation];}Nsarray*operations = [afurlconnectionoperation batchofrequestoperations:@[...] progressblock:^ (NSUInteger Numberoffinishedoperations, Nsuinteger totalnumberofoperations) {NSLog(@"%lu of%lu Complete", Numberoffinishedoperations, totalnumberofoperations);} completionblock:^ (Nsarray*operations) {NSLog(@"All operations in batch complete");}]; [[Nsoperationqueue Mainqueue] addoperations:operations waituntilfinished:NO];

The above is some common methods in afnetworking, afnetworking request to the data, automatically parse the requested data, iOS data request This aspect afnetworking is a very good third-party library.
