iOS菜鳥之AFN的二次封裝，iosafn二次封裝

我用一個單例類將一些常用的網路請求進行了二次封裝，主要包括post請求 get請求  圖片檔案上傳下載  視頻的斷點續傳等功能。

首先大家先去github上下載AFN，將檔案夾內的AFNetworking檔案夾拖入工程中，然後建立一個圖片檔案參數類代碼如下：

#import <Foundation/Foundation.h>@interface UploadParam : NSObject/** *  上傳檔案的位元據 */@property (nonatomic, strong) NSData *data;/** *  上傳的參數名稱 */@property (nonatomic, copy) NSString *name;/** *  上傳到伺服器的檔案名稱 */@property (nonatomic, copy) NSString *fileName;/** *  上傳檔案的類型 */@property (nonatomic, copy) NSString *mimeType;@end

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

然後建立網路工具AFNManager具體代碼如下(此處我提供了代理和block兩種方式進行傳值供大家選擇)：

#import <Foundation/Foundation.h>#import "AFNManagerDelegate.h"#import "UploadParam.h"@interface AFNManager : NSObject@property (nonatomic, weak) id<AFNManagerDelegate> delegate;/** *  AFNManager單利 */+(AFNManager *)sharedManager;#pragma mark --代理的方式傳值/** *  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 --block的形式傳值/** *  get請求 */- (void)GET:(NSString *)URLString parameters:(id)parameters succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure;/** *  post請求 */- (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 --斷點續傳/** *  開始下載  斷點續傳 * *  @param URLString 請求介面 */- (void)downloadStartWithUrl:(NSString *)URLString fileName:(NSString *)fileName;/** *  開始上傳  斷點續傳 * *  @param URLString 請求介面 */- (void)uploadStartWithUrl:(NSString *)URLString fileData:(NSData *)fileData;/** *  暫停操作  斷點續傳 */- (void)operationPause;/** *  繼續操作  斷點續傳 */- (void)operationResume;/** *  取消操作 */- (void)operationCancel;@end

網路工具代理協議代碼如下：

#import <Foundation/Foundation.h>@class AFNManager;@protocol AFNManagerDelegate <NSObject>@optional/** *  發送請求成功 * *  @param manager AFNManager */-(void)AFNManagerDidSuccess:(id)data;/** *  發送請求失敗 * *  @param manager AFNManager */-(void)AFNManagerDidFaild:(NSError *)error;@end

有很多不足之處請大家多多指正，可以評論或點關注進行技術交流。後續也會寫一些自己平時學習的點點滴滴。
