Question

我收到此错误“由于未捕获的异常终止应用AmazonServiceException，原因：'（null）'”请求从S3获取对象时，这是我的代码：< / p>

 AmazonS3Client *s3 = [[AmazonS3Client alloc] initWithAccessKey:ACCESS_KEY_ID
                                                     withSecretKey:SECRET_KEY];
    S3TransferManager *tm = [S3TransferManager new];
    tm.s3 = s3;

    S3GetObjectRequest *getObjectRequest = [[S3GetObjectRequest alloc] initWithKey:@"1234/history.json" withBucket:S3TRANSFERMANAGER_BUCKET];
    [s3 getObject:getObjectRequest];

    S3GetObjectResponse *getObjectResponse = [s3 getObject:getObjectRequest];



    NSData *data = getObjectResponse.body;
    NSError *error = nil;
    NSArray *jsonArrayNewObject = [NSJSONSerialization JSONObjectWithData:json options:kNilOptions error:&error];
    NSArray *jsonArrayHistoryObject = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
    NSMutableArray *historyList = [jsonArrayHistoryObject mutableCopy];

    [historyList addObjectsFromArray:jsonArrayNewObject];

    NSDictionary *dictionary = [[NSDictionary alloc] init];
    dictionary = [historyList mutableCopy];

    NSData *jsonData = [NSJSONSerialization
                        dataWithJSONObject:dictionary
                        options:NSJSONWritingPrettyPrinted
                        error:&error];

    [self upload:jsonData];

我将看一下AWS iOS SDK的iOS示例应用程序部分：https://github.com/awslabs/aws-sdk-ios-samples

它包含S3文件传输（上传和下载）示例
