Загрузка файла в Amazon S3 из iOS приложения

Шаг 1

Настроить iOS проект.

Шаг 2

Сделать свою имплементацию протокола AWSCredentialsProvider.

//
//  MyCredentialsProvider.h
//

#import <Foundation/Foundation.h>
#import "S3.h"
#import "AWSCore.h"

@interface MyCredentialsProvider : NSObject <AWSCredentialsProvider>

@property (nonatomic, strong) NSString *accessKey;
@property (nonatomic, strong) NSString *secretKey;
@property (nonatomic, strong) NSString *sessionKey;
@property (nonatomic, strong) NSDate *expiration;

- (BFTask *)refresh;

@end


//
//  MyCredentialsProvider.m
//

#import "MyCredentialsProvider.h"

@implementation MyCredentialsProvider

@end

Шаг 3

Подключить заголовочные файлы:

#import "S3.h"
#import "AWSCore.h"

Шаг 4

Написать код для загрузки файла в облачное хранилище Amazon S3:

MyCredentialsProvider *theMyCredentialsProvider = [[MyCredentialsProvider alloc] init];
theMyCredentialsProvider.accessKey = @"ASIAI26Q4VETSVHRX4ZQ";
theMyCredentialsProvider.secretKey = @"aCx1FWmZ+b38bhXTANwBgDsAtLfESlYRq3nXgPNu";
theMyCredentialsProvider.sessionKey = @"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";

AWSServiceConfiguration *theConf = [AWSServiceConfiguration configurationWithRegion:AWSRegionEUCentral1 credentialsProvider:theMyCredentialsProvider];

AWSS3TransferManager *transferManager = [[AWSS3TransferManager alloc] initWithConfiguration:theConf identifier:@"S3"];

AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
uploadRequest.bucket = @"example.com/a/b/";
uploadRequest.key = @"My File.txt";
uploadRequest.body = [NSURL fileURLWithPath:@"/Users/Devtype/Documents/My File.txt"];

[[transferManager upload:uploadRequest] continueWithExecutor:[BFExecutor mainThreadExecutor]
   withBlock:^id(BFTask *task) {
       if (task.error) {
           if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
               switch (task.error.code) {
                   case AWSS3TransferManagerErrorCancelled:
                   case AWSS3TransferManagerErrorPaused:
                       break;
                       
                   default:
                       NSLog(@"Error: %@", task.error);
                       break;
               }
           } else {
               // Unknown error.
               NSLog(@"Error: %@", task.error);
           }
       }
       
       if (task.result) {
           AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
           // The file uploaded successfully.
           NSLog(@"The file uploaded successfully.");
       }
       return nil;
   }];
