Ios7 setAuthorizationHeaderWithUsername:密码：在多部分网络2.0中

我正在使用以下代码进行多媒体上传

NSMutableArray *mutableOperations = [NSMutableArray array];

    for (id obj in mediaArray)
    {


        NSURLRequest *request=[[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"MY URL" parameters:@"MY PARAMS" constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

            [formData appendPartWithFileURL:@"MY URL" name:@"MY File Name" error:nil];


        } error:&er];

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

        NSURLCredential *credential = [NSURLCredential credentialWithUser:PushuserNameAutheitcation password:PushpasswordAutheitcation persistence:NSURLCredentialPersistenceNone];

    }

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

NSMutableArray*mutableOperations=[NSMutableArray]；
用于（mediaArray中的id obj）
{
NSURLRequest*request=[[AFHTTPRequestSerializer]multipartFormRequestWithMethod:@“POST”URLString:@“MY URL”参数：@“MY PARAMS”constructingBodyWithBlock:^（id formData）{
[formData appendPartWithFileURL:@“我的URL”名称：@“我的文件名”错误：无]；
}错误：&er]；
AFHTTPRequestOperation*操作=[[AFHTTPRequestOperation alloc]initWithRequest:request]；
NSURLCredential*credential=[nsurlCredentialCredentialWithUser:PushUserName身份验证密码：PushPasswordAuthentication持久性：nsurlCredentialPersistenceOne]；
}
NSArray*operations=[AFURLConnectionOperation BatchOfRequesToOperations:mutableOperations progressBlock:^（NSInteger numberOfFinishedOperations，NSInteger totalNumberOfOperations）{
NSLog（@“%lu/lu完成”，numberOfFinishedOperations，totalNumberOfOperations）；
}completionBlock:^（NSArray*操作）
{
完成（真实、无、无）；
} ];
[[NSOperationQueue mainQueue]添加操作：操作等待完成：否]；

我想添加授权标头。我该如何做？

请尝试使用此代码传递授权标头

NSURLMutableRequest *request = [NSURLMutableRequest requestWithURL:[NSURL URLWithString:fileURL]];
NSData* authData = [[[NSString stringWithFormat:@"Username:Password"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] dataUsingEncoding: NSASCIIStringEncoding];
NSString *auth = [authData base64EncodedString];
auth = [NSString stringWithFormat:@"Basic %@",auth];
[request setValue:auth forHTTPHeaderField:@"Authorization"];

否则

NSURLCredential *credential = [NSURLCredential credentialWithUser:@"Login" 
password:@"Password" persistence:NSURLCredentialPersistenceForSession];
[operation setCredential:credential];
