1、OSS连接[官方连接][Link 1]

2、下载SDK:

通过GitHub下载
    pod依赖： pod 'AliyunOSSiOS'
    demo地址： https://github.com/aliyun/aliyun-oss-ios-sdk

3、创建一个类  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtaWxlS0g_size_16_color_FFFFFF_t_70_pic_center]  
4、.h文件属性方法：

#import <Foundation/Foundation.h>
    #import <UIKit/UIKit.h>
    
    typedef NS_ENUM(NSInteger, UploadImageState) {
        UploadImageFailed   = 0,
        UploadImageSuccess  = 1
    };
    // 当前上传段长度、当前已经上传总长度、一共需要上传的总长度
    typedef void(^HBUploadImageManageProgressBlock)(int64_t bytesSent, int64_t totalByteSent ,int64_t totalBytesExpectedToSend);
    
    @interface HBUploadImageManage : NSObject
    
    + (void)asyncUploadImage:(UIImage *)image tempImgFolder:(NSString *)TempImgFolder progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names,UploadImageState state))complete;
    
    + (void)syncUploadImage:(UIImage *)image tempImgFolder:(NSString *)TempImgFolder progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names,UploadImageState state))complete;
    
    + (void)asyncUploadImages:(NSArray<UIImage *> *)images tempImgFolder:(NSString *)TempImgFolder progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names, UploadImageState state))complete;
    
    + (void)syncUploadImages:(NSArray<UIImage *> *)images tempImgFolder:(NSString *)TempImgFolder  progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names, UploadImageState state))complete;
    //上传视频
    + (void)asyncUploadVideo:(NSData *)data tempVideoFolder:(NSString *)TempVideoFolder progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names, UploadImageState state))complete;
    + (void)syncUploadVideo:(NSData *)data tempVideoFolder:(NSString *)TempVideoFolder progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names, UploadImageState state))complete;
    @end

5、.m文件属性方法

#import "HBUploadImageManage.h"
    #import <AliyunOSSiOS/OSSService.h>
    @implementation HBUploadImageManage

    static NSString *const AccessKey = @"";

    static NSString *const BucketName = @"";
    static NSString *const AliYunHost = @"";
    //static NSString *const AliYunHost = @"";
    //static NSString *kTempImgFolder = @"ios/img";
    //static NSString *kTempVideoFolder = @"ios/video";
    static NSString *rootUrl = @"";
    
    
    + (void)asyncUploadImage:(UIImage *)image tempImgFolder:(NSString *)TempImgFolder progress:(HBUploadImageManageProgressBlock)progressBlock complete:(void(^)(NSArray<NSString *> *names,UploadImageState state))complete
