Appendable Upload

Appendable upload allows you to upload an object in appending mode and then append data to the object. You can call appendObject to perform appendable upload. Sample code is as follows:

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"FileName" ofType:@"FileSuffix"];
    NSFileManager *manager = [NSFileManager defaultManager];
    NSDictionary *fileDic = [manager attributesOfItemAtPath:filePath error:nil];
    unsigned long long size = [[fileDic objectForKey:NSFileSize] longLongValue];
    int filesize = size;
    //Create an object in appendable mode.
    OBSAppendObjectWithFileRequest *request = [[OBSAppendObjectWithFileRequest alloc] initWithBucketName:@"bucketName" objectKey:@"objectname" uploadFilePath:filePath];
    request.position = [NSNumber numberWithFloat:0];
    
    request.uploadProgressBlock =  ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
        NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
        
    };
    [client appendObject:request completionHandler:^(OBSAppendObjectResponse *response, NSError *error) {
        NSLog(@"%@",response);
        //Start position for next appending
       Int position = response.nextPosition;
    }];
    
    //Append data to the object.
    OBSAppendObjectWithFileRequest *request = [[OBSAppendObjectWithFileRequest alloc] initWithBucketName:@"bucketName" objectKey:@"objectname" uploadFilePath:filePath];
    request.position = [NSNumber numberWithFloat:size];
    
    request.uploadProgressBlock =  ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
        NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
        
    };
    [client appendObject:request completionHandler:^(OBSAppendObjectResponse *response, NSError *error) {
        NSLog(@"%@",response);
        //Start position for next appending
        Int position = response.nextPosition;
    }];
