iphone - 保存录制的视频

Question

请任何人提供任何示例代码来在录制后保存视频。我可以使用 UIImagePickerController 录制视频。

if (canShootVideo) {
        UIImagePickerController *videoRecorder = [[UIImagePickerController alloc] init];
        videoRecorder.sourceType = UIImagePickerControllerSourceTypeCamera;
        videoRecorder.delegate = self;

        NSArray *mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
        NSArray *videoMediaTypesOnly = [mediaTypes filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(SELF contains %@)", @"movie"]];
        BOOL movieOutputPossible = (videoMediaTypesOnly != nil);

        if (movieOutputPossible) {
            videoRecorder.mediaTypes = videoMediaTypesOnly;

            [self presentModalViewController:videoRecorder animated:YES];           
        }
        [videoRecorder release];
    }

但是如何保存它。谁能告诉一下吗？

提前致谢

Answer 1

- (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];
    }

}

这适用于您想要将视频保存到您可以控制的某个文件路径的情况。您也可以保存到“已保存的照片”
