  if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
  {


    NSArray *mediaTypes = [NSArray arrayWithObject:(NSString*)kUTTypeMovie];
    picker.mediaTypes = mediaTypes ;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo ;

    [self presentModalViewController:picker animated:NO];

    [picker release];


}
  else
    {

UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"Error" message:@" Camera Facility is not available with this Device" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alt show];
    [alt release];
    }


试试这个,我是用当前日期时间存储它::

Try this, I've stored it with current Date-Time ::

-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
    [self dismissViewControllerAnimated:NO completion:nil];
    NSString *type = [info objectForKey:UIImagePickerControllerMediaType];

    if ([type isEqualToString:(NSString *)kUTTypeVideo] || [type isEqualToString:(NSString *)kUTTypeMovie])
    {
        videoURL = [info objectForKey:UIImagePickerControllerMediaURL];

        NSLog(@"found a video");

        // Code To give Name to video and store to DocumentDirectory //

        videoData = [[NSData dataWithContentsOfURL:videoURL] retain];
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];

        NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] init] autorelease];
        [dateFormat setDateFormat:@"dd-MM-yyyy||HH:mm:SS"];
        NSDate *now = [[[NSDate alloc] init] autorelease];
        theDate = [dateFormat stringFromDate:now];

        NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"Default Album"];

        if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
           [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil];

        NSString *videopath= [[[NSString alloc] initWithString:[NSString stringWithFormat:@"%@/%@.mov",documentsDirectory,theDate]] autorelease];

        BOOL success = [videoData writeToFile:videopath atomically:NO];

        NSLog(@"Successs:::: %@", success ? @"YES" : @"NO");
        NSLog(@"video path --> %@",videopath);
    }
}

视频上传::

videoData 来自 videoData = [[NSData dataWithContentsOfURL:videoURL] retain];

- (void)uploadVideo
{
    NSData *imageData = videoData;

    NSString *urlString=[NSString stringWithFormat:@"%s", UploadVideoService];
    NSLog(@"url=== %@", urlString);

    request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSString *boundary = @"---------------------------14737809831466499882746641449";
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

    /*  body of the post */

    NSMutableData *body = [NSMutableData data];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    //Video Name with Date-Time
    NSDateFormatter *dateFormat=[[NSDateFormatter alloc]init];
    [dateFormat setDateFormat:@"yyyy-MM-dd-hh:mm:ssa"];
    NSString *currDate = [dateFormat stringFromDate:[NSDate date]];

    NSString *str = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"video-%@.mov\"\r\n", currDate];
    NSLog(@"String name::  %@",str);

    [dateFormat release];

    [body appendData:[[NSString stringWithString:str] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [request setHTTPBody:body];

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

    NSLog(@"result from webservice:::--> %@", returnString);

    [returnString release];
}

希望,它会帮助你。

谢谢。
