上传多张图片

OSSPutObjectRequest * put = [OSSPutObjectRequest new];

put.bucketName = @"fzyouke";
put.objectKey = [NSString stringWithFormat:@"klxz/taskios/%@.jpg",name];
put.uploadingFileURL = [NSURL fileURLWithPath:urlpath];
put.uploadProgress = ^(int64_t bytesSent, int64_t totalByteSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%lld, %lld, %lld", bytesSent, totalByteSent, totalBytesExpectedToSend);
};
OSSTask * putTask = [ossclient putObject:put];

[putTask continueWithBlock:^id(OSSTask *task) {
    NSLog(@"objectKey: %@---tsak-->>%@", put.objectKey,task.error);
    if (!task.error) {
        NSLog(@"upload object success!");
    } else {
        NSLog(@"upload object failed, error: %@" , task.error);
    }
    return nil;
}];

我想一次性上传 9张。怎么操作？？？
