IOS cainiao's AFN secondary encapsulation and iosafn secondary Encapsulation

I used a singleton class to encapsulate some common network requests, including the resumable upload and download functions of the get request for post requests for uploading and downloading image files.

First, download AFN from github, drag the AFNetworking folder in the folder into the project, and then create an image file parameter class Code as follows:

# Import <Foundation/Foundation. h> @ interface UploadParam: NSObject/*** uploads binary data of a file */@ property (nonatomic, strong) NSData * data; /*** name of the uploaded parameter */@ property (nonatomic, copy) NSString * name;/*** name of the file uploaded to the server */@ property (nonatomic, copy) NSString * fileName;/*** upload file type */@ property (nonatomic, copy) NSString * mimeType; @ end

#import "UploadParam.h"@implementation UploadParam@end

The specific code for creating the network tool AFNManager is as follows (here I provide two methods for you to pass values through proxy and block ):

# Import <Foundation/Foundation. h> # import "AFNManagerDelegate. h "# import" UploadParam. h "@ interface AFNManager: NSObject @ property (nonatomic, weak) id <AFNManagerDelegate> delegate;/*** AFNManager */+ (AFNManager *) sharedManager; # pragma mark -- pass the value as a proxy/*** get */-(void) GET :( NSString *) URLString parameters :( id) parameters; /*** post */-(void) Post :( NSString *) URLString parameters :( id) parameters;/*** upload */-(void) Upload :( NSString *) URLString parameters :( id) parameters uploadParam :( UploadParam *) uploadParam; # pragma mark-pass the value in the form of block/*** get request */-(void) GET :( NSString *) URLString parameters :( id) parameters succeed :( void (^) (id data) succeed failure :( void (^) (NSError * error) failure; /*** post Request */-(void) Post :( NSString *) URLString parameters :( id) parameters succeed :( void (^) (id data )) succeed failure :( void (^) (NSError * error) failure;/*** upload */-(void) Upload :( NSString *) URLString parameters :( id) parameters uploadParam :( UploadParam *) uploadParam succeed :( void (^) (id data) succeed failure :( void (^) (NSError * error) failure; # pragma mark -- resumable download/*** start to download resumable download ** @ param URLString request interface */-(void) downloadStartWithUrl :( NSString *) URLString fileName :( NSString *) fileName;/*** start to upload resumable upload ** @ param URLString request interface */-(void) uploadStartWithUrl :( NSString *) URLString fileData :( NSData *) fileData; /*** pause the resumable upload operation */-(void) operationPause;/*** resume the resumable upload operation */-(void) operationResume; /*** cancel Operation */-(void) operationCancel; @ end

The network tool proxy protocol code is as follows:

# Import <Foundation/Foundation. h> @ class AFNManager; @ protocol AFNManagerDelegate <NSObject> @ optional/*** request sent successfully ** @ param manager AFNManager */-(void) AFNManagerDidSuccess :( id) data; /*** failed to send the request ** @ param manager AFNManager */-(void) AFNManagerDidFaild :( NSError *) error; @ end

If you have many shortcomings, please comment on them or pay attention to them for technical exchanges. In the future, I will also write some of my daily learning experiences.
