Question

我有一系列图像，我尝试使用AFNetworking批量请求上传到服务器。这是我的代码，我收到了错误，我不知道为什么

-(void)imageUploader {


    NSArray *imageArray = _listing.productImageArray;


    imageCounter = 1;

    NSString * ts = [NSString stringWithFormat:@"%f",[[NSDate new] timeIntervalSince1970] * 1000];
    NSMutableArray *mutableOperations = [NSMutableArray array];

    for (NSURL *fileURL in imageArray) {

        imagesUploaded = 0;

        NSString *counter = [NSString stringWithFormat:@"%i", imageCounter];


        NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"https://myayla.com/bl/saveProductImages.php" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            [formData appendPartWithFileURL:fileURL name:@"images[]" error:nil];
        } error:nil];

        AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

        [mutableOperations addObject:operation];
    }

    NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:mutableOperations progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {
        NSLog(@"%lu of %lu complete", numberOfFinishedOperations, totalNumberOfOperations);
    } completionBlock:^(NSArray *operations) {
        NSLog(@"All operations in batch complete");
    }];
    [[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];

这是错误

'NSInvalidArgumentException', reason: '-[UIImage lastPathComponent]: unrecognized selector sent to instance

任何人都可以帮忙吗？感谢

图像阵列肯定是一个URL数组吗？在某个地方，有人期待一个字符串，但他们正在获得一个图像。基于：在UIImage上调用lastPathComponent（NSString方法）。

使用AFNetworking 2批量请求上载图像阵列
