如何将录制的video保存到相册中？

以下代码是将从相机拍摄的图像保存到相册中。

if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) { image = [info objectForKey:UIImagePickerControllerEditedImage]; UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:finishedSavingWithError:contextInfo:), nil); } 

如何将重新录制的video保存到相册中？

Answer 1

检查下面的代码…

  - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; if ([mediaType isEqualToString:@"public.movie"]){ // Saving the video / // Get the new unique filename NSString *sourcePath = [[info objectForKey:@"UIImagePickerControllerMediaURL"]relativePath]; UISaveVideoAtPathToSavedPhotosAlbum(sourcePath,nil,nil,nil); } 

Answer 2

 - (void)saveMovieToCameraRoll { ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; [library writeVideoAtPathToSavedPhotosAlbum:movieURL completionBlock:^(NSURL *assetURL, NSError *error) { if (error) [self showError:error]; else [self removeFile:movieURL]; dispatch_async(movieWritingQueue, ^{ recordingWillBeStopped = NO; self.recording = NO; [self.delegate recordingDidStop]; }); }]; [library release]; } 

这是苹果示例rosywriter的代码片段。 可以工作。

  movieURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@%@", NSTemporaryDirectory(), @"Movie.MOV"]]; [movieURL retain]; 

以上几行为video创build文件和path。

 - (void) startRecording { dispatch_async(movieWritingQueue, ^{ if ( recordingWillBeStarted || self.recording ) return; recordingWillBeStarted = YES; // recordingDidStart is called from captureOutput:didOutputSampleBuffer:fromConnection: once the asset writer is setup [self.delegate recordingWillStart]; // Remove the file if one with the same name already exists [self removeFile:movieURL]; // Create an asset writer NSError *error; assetWriter = [[AVAssetWriter alloc] initWithURL:movieURL fileType:(NSString *)kUTTypeQuickTimeMovie error:&error]; if (error) [self showError:error]; }); } 

此function用于使用avassetwriter开始将video录制到该movieURL文件中。

Answer 3

尝试下面的代码

 - (void)saveVideo:(NSURL *)videoUrl { NSData *videoData = [NSData dataWithContentsOfURL:videoUrl]; [videoData writeToFile:@"YOUR_PATH_HERE" atomically:YES]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSString *type = [mediaDict objectForKey:UIImagePickerControllerMediaType]; if ([type isEqualToString:(NSString *)kUTTypeVideo] || [type isEqualToString:(NSString *)kUTTypeMovie]) { // movie != video NSURL *videoURL [mediaDict objectForKey:UIImagePickerControllerMediaURL]; [self saveVideo:videoUrl]; } }

或者你也可以试试这个将video保存到文档目录如下

  - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL]; NSData *videoData = [NSData dataWithContentsOfURL:videoURL]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *tempPath = [documentsDirectory stringByAppendingFormat:@"/vid1.mp4"]; BOOL success = [videoData writeToFile:tempPath atomically:NO]; [picker dismissModalViewControllerAnimated:YES]; }
