Question

如何检查AFNetworking是否已完成文件上传？我怎么能检查是否有问题？

这是我的代码：

AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://server"]];
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:[fieldName text] forKey:@"name"];
[parameters setObject:[fieldSurname text] forKey:@"surname"];

NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"/upload.php" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData:[[AttachedFile sharedAttachedFile]dataToSend] mimeType:@"image/jpeg" name:@"attach"];
}];

AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] initWithRequest:myRequest] autorelease]; 
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
    NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];

queue = [[[NSOperationQueue alloc] init] autorelease];
[queue addOperation:operation];

我应该实现哪个方法（和委托）？

谢谢！

Answer 1

使用

[AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest
                                                success:(void (^)(id object))success 
                                                failure:(void (^)(NSHTTPURLResponse *response, NSError *error))failure];

而不是

AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] initWithRequest:myRequest] autorelease];

当您的文件完全上传时，将调用成功块。如果出现问题，则调用失败块。

不推荐使用

HTTPRequestOperationWithRequest ，最好在AFHTTPRequestOperation实例上使用 setCompletionBlockWithSuccess：failure
