【问题描述】：

我正在从 iPad 应用程序录制视频，我希望该视频可以保存在文档文件夹中，或者我们可以直接将其上传到服务器。我已将音频文件存储在文档中，但如何保存视频文件。我正在使用以下代码录制视频。

  UIImagePickerController *picker = [[UIImagePickerController alloc] init];
  picker.delegate = self;

  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];
    }

【问题讨论】：

@Popeye 你可以看到这个问题是如何录制视频但问题不是保存这就是我问这个问题的原因所以不需要-1
您接受的答案告诉您如何保存和记录。你不应该问另一个完全相同的问题，这就是我给你-1的原因。如果它不起作用，那么您不应该接受答案，因为这会误导其他用户。
@Popeye 好的，我知道了
老实说，您也有关于将数据发布到服务器的问题。它不是重复的，但您可以将两个和两个放在一起以获得您的答案。

试试这个，我已经用当前日期时间存储了它::

-(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];
}

希望对你有帮助。

谢谢。

这个方法会自动调用
当您点击“使用”按钮时，它会自动调用。我刚刚在这个方法中的 doc dir 中添加了用于保存视频的代码。
当我想把它上传到服务器时，我将如何访问这个路径
什么是视频 url 的数据类型，我必须标记它给错误的变量
@iManan 如果您从未在代码中释放某些对象，那么您有一个小的内存泄漏并不重要。 +1 虽然除了这是一个很好的答案。

【解决方案2】：

//for video..
#import <MobileCoreServices/MobileCoreServices.h>
#import <AVFoundation/AVFoundation.h>
#import <MediaPlayer/Mediaplayer.h>

#import <CoreMedia/CoreMedia.h>



UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;

    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];
    }

用于保存到文档文件夹，也可以保存在照片库中

NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString* documentsDirectory = [paths objectAtIndex:0];


        //for video
        NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
        NSLog(@"video url-%@",videoURL);

        NSData *videoData = [NSData dataWithContentsOfURL:videoURL];

        NSString * videoName = [NSString stringWithFormat:@"student_%d_%d.mp4",stud_id,imgVidID];

        videoPath = [documentsDirectory stringByAppendingPathComponent:videoName];

        NSLog(@"video path-%@",videoPath);

        [videoData writeToFile:videoPath atomically:YES];

        NSString *sourcePath = [[info objectForKey:@"UIImagePickerControllerMediaURL"]relativePath];

        UISaveVideoAtPathToSavedPhotosAlbum(sourcePath,nil,nil,nil);
}

一旦这样尝试，

- (void)imagePickerController:(UIImagePickerController *)imagePicker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{

    NSURL *videoUrl = (NSURL *)[info objectForKey:UIImagePickerControllerMediaURL]; 

    NSDate *now = [NSDate date];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    dateFormatter.dateFormat = @"hh:mm:ss";
    [dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];

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

    NSString *savedvedioPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:now]]];
    savedvedioPath  = [savedvedioPath stringByAppendingFormat:@".mp4"];
    [videoData writeToFile:savedvedioPath atomically:NO];

    //here is the method to upload onto server
    [self Upload_server:savedvedioPath];

    [self dismissModalViewControllerAnimated:YES];
}

现在定义您上传视频的方法，

-(void)Upload_server:(NSString*)file_path {

  NSURL *url = [NSURL URLWithString: @"YOUR_URL_TO_UPLOAD"];
  ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
  [request setUseKeychainPersistence:YES];
  [request addFile:file_path forKey:@"YOUR_KEY"];

//insted of in above line you can also use [request setData:vedioData withFileName:@"your_file_name" andContentType:@"video/mp4" forKey:@"YOUR_KEY"] by Sending  vedioData of type NSData as another perameter to this method.

[request setDelegate:self];
[request setDidFinishSelector:@selector(uploadRequestFinished:)];
[request setDidFailSelector:@selector(uploadRequestFailed:)];
[request startAsynchronous];

}

现在实现 ASIFormDataRequest 委托方法，例如，

- (void)uploadRequestFinished:(ASIHTTPRequest *)request{ 

   NSString *responseString = [request responseString];
  //do something after sucessful upload

}

- (void)uploadRequestFailed:(ASIHTTPRequest *)request{

  NSLog(@" Error - Statistics file upload failed: \"%@\"",[[request error] localizedDescription]); 

  }

在这里，我将 ASIFormDataRequest 上传到服务器。希望它会帮助你..
