【问题描述】：

我有一个问题，录制视频后，我点击使用按钮将此视频保存到库，但保存完成后，我无法点击播放按钮或重拍按钮。这是我的代码：

  -(void)actionLaunchAppCamera

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    
        UIImagePickerController * imagePickerController = [[UIImagePickerController alloc] init];

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])  
            imagePickerController.mediaTypes =  [NSArray arrayWithObject:(NSString *)kUTTypeMovie];
            imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
            imagePickerController.showsCameraControls = YES;
            imagePickerController.allowsEditing = YES;
            imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
            imagePickerController.delegate = self;
            imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceRear;

            [self presentModalViewController:imagePickerController animated:YES];
            //[imagePickerController release];
        
    

保存拍摄的图像

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    NSURL *recordedVideoURL= [info objectForKey:UIImagePickerControllerMediaURL];

    if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:recordedVideoURL]) 
        [library writeVideoAtPathToSavedPhotosAlbum:recordedVideoURL
                completionBlock:^(NSURL *assetURL, NSError *error)
                    [library assetForURL:assetURL resultBlock:^(ALAsset *asset) 
                        NSDate* date = [asset valueForProperty:ALAssetPropertyDate];
                        NSLog(@"Date Time Modify %@",date);
                        NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];
                        [formatter setDateFormat: @"dd.MM.yyyy HH:mm:ss"];
                        NSString* CurrentDateStamp = [formatter stringFromDate:date];

                        NSLog(@"NameVideo %@",asset.defaultRepresentation.filename);
                        NSLog(@"DateModify %@",CurrentDateStamp);
                        NSLog(@"Size: %lld", asset.defaultRepresentation.size);
                     failureBlock:nil];

 actionSheetUpload= [[UIActionSheet alloc] initWithTitle:@"Do you want to upload this video?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Upload" otherButtonTitles:nil];
                actionSheetUpload.actionSheetStyle = UIActionSheetStyleBlackOpaque;
                [actionSheetUpload showInView:[UIApplication sharedApplication].keyWindow];
                [actionSheetUpload release];
                
         ];
    
   [library release];

有什么想法吗？提前致谢

【问题讨论】：

那么要玩的代码在哪里..？您只是保存视频，之后需要播放视频

保存视频后，我会将此视频上传到服务器。我更新了问题中的代码。

那你应该用播放器来玩吧？

【参考方案1】：

也许您不会使用 - (void)dismissViewControllerAnimated: (BOOL)flag completion: (void (^)(void))completion 关闭选择器

【参考方案2】：

该代码非常适合保存视频，如果您想播放它。然后你需要使用播放器来播放它。

例如：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
    NSURL *recordedVideoURL= [info objectForKey:UIImagePickerControllerMediaURL];
.// Save Your Stuff
.
.

     MPMoviePlayerController *movieplayer =[[MPMoviePlayerController alloc] initWithContentURL: recordedVideoURL];    
    [[movieplayer view] setFrame: 
    [self.view bounds]];  
    [self.view addSubview: 
    [movieplayer view]];
    [movieplayer play];

编辑： 对于上传视频，根据您的代码： 声明NSURL *recordedVideoURL;

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
    //NSLog(@"but ind %d", buttonIndex);
    if (buttonIndex == uploadBTnIndex) 
     NSData *videoData = [NSData dataWithContentsOfURL:recordedVideoURL];
   //Use this NSData to upload, So what else your problem to upload using web Services ?

【讨论】：

谢谢，但我不需要播放视频。我只需要将它上传到服务器。

那是什么问题，你要求我在完成（保存）后做上传代码。

我的问题是点击Use video后，它会显示Actionsheet Uploading，然后我点击Actionsheet上的Cancel来支持UIImagePickercontroller，但是UIImagePickerController似乎无法点击任何按钮。
