小编mar*_*ian的帖子

我开发了一个显示错误的项目:

不推荐使用'UIPopoverController':首先在iOS 9.0中弃用 - 不推荐使用UIPopoverController.弹出窗口现在实现为UIViewController演示.使用UIModalPresentationPopover和UIPopoverPresentationController的模态表示样式.

我的编纂是:

ViewController.h:

#import <UIKit/UIKit.h>
#import <Photos/Photos.h>
#import <MobileCoreServices/MobileCoreServices.h>



@interface ViewController : UIViewController
 <UIImagePickerControllerDelegate, UINavigationControllerDelegate>

- (IBAction)touch:(id)sender;

@end

@interface SecondView : UIViewController
<UIImagePickerControllerDelegate, UINavigationControllerDelegate>



//video gallery
@property (strong,nonatomic) UIPopoverPresentationController *popOver;
@property (weak, nonatomic) IBOutlet UIView *studentView;
@property (strong, nonatomic) NSURL *videoURL;


@end

ViewController.m:

- (void)openGallery {

UIImagePickerController *Picker=[[UIImagePickerController alloc] init];
Picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
Picker.mediaTypes=[[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie,  nil];
Picker.delegate=self;

if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

{


    UIPopoverController *popController=[[UIPopoverController alloc] initWithContentViewController:Picker];
    [popController presentPopoverFromRect:CGRectMake(0, 600, 160, 300) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    self.popOver=popController;
} …

我一直在努力将Facebook分享整合到我的应用程序中.但我不断收到以下错误:
