Question

我从iphone库导入视频在我的应用程序中......但是我无法显示我在堆栈上研究了大量代码但是没有工作..对我来说...基本上我正在分享fb和推特... ..

-(IBAction)showVideoLibrary
{
UIImagePickerController *videoPicker = [[UIImagePickerController alloc] init];
videoPicker.delegate = self;
videoPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

videoPicker.mediaTypes =[[NSArray alloc] initWithObjects: (NSString *)kUTTypeMovie,nil];    
if(self.popoverController!=nil)
{
    [self.popoverController release];
}
self.popoverController  = [[UIPopoverController alloc] initWithContentViewController:videoPicker];
popoverController.delegate = self;
popoverController.popoverContentSize=CGSizeMake(320,1000);

[popoverController presentPopoverFromRect:CGRectMake(0,0,10,10) inView:self.view permittedArrowDirections:nil animated:YES];

}

提前致谢

在真正的iPhone设备上试试吧。这是从我的项目中使用的iPhone库中挑选视频的代码。只需将选择器中的视频方法添加到所需的按钮即可。

-(void)video
     {
     UIImagePickerController *imagePicker =
     [[UIImagePickerController alloc] init];
     imagePicker.delegate = self;
     imagePicker.sourceType = 
     UIImagePickerControllerSourceTypePhotoLibrary;


     imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];

     [self presentModalViewController:imagePicker animated:YES];


     }


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


     NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];

     if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0)
     == kCFCompareEqualTo) 
     {

     NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

       NSURL *videoUrl=(NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
     // NSLog(@"%@",moviePath);

     if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
     UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
     }
     }


     [self dismissModalViewControllerAnimated:YES];

     [picker release];


     }

不要忘记添加移动核心服务框架并导入

 #import <MobileCoreServices/UTCoreTypes.h>

字符串“moviepath”为您提供iPhone中视频的路径，然后对该视频执行任何所需的操作压缩完成后，您将在字符串电影路径enter code here

中获得视频路径

 MPMoviePlayerController *player =[[MPMoviePlayerController alloc] initWithContentURL: url];   //  give here the "videourl"  
 [[player view] setFrame: [self.view bounds]];  
 [self.view addSubview: [player view]];
 [player play];
