我开发了一个显示错误的项目：

'UIPopoverController' 已弃用：首先在 iOS 9.0 中弃用 - UIPopoverController 已弃用。弹出框现在实现为 UIViewController 演示文稿。使用 UIModalPresentationPopover 和 UIPopoverPresentationController 的模态表示样式。

我的编码是：

视图控制器.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

视图控制器.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;
}
else
{
    [self presentViewController:Picker animated:YES completion:nil];
}
}


#pragma mark - UIImagePickerControllerDelegate

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


if (self.studentView) {

    self.videoURL = info[UIImagePickerControllerMediaURL];
    [picker dismissViewControllerAnimated:YES completion:NULL];


    [[NSUserDefaults standardUserDefaults] setObject:[self.videoURL absoluteString] forKey:@"url1"];
}

}

我无法正确参考 UiModalPresentationPopover。有人可以帮我解决这个错误。任何帮助深表感谢。谢谢你。

使用 UIModalPresentationPopover

在水平规则环境中，内容显示在弹出视图中的一种演示风格。背景内容变暗，在弹出框外点击会导致弹出框被关闭。如果您不希望点击关闭弹出框，您可以将一个或多个视图分配给关联的 UIPopoverPresentationController 对象的 passthroughViews 属性，您可以从 popoverPresentationController 属性中获取该属性。

在水平紧凑的环境中，此选项的行为与 UIModalPresentationFullScreen 相同。

在 iOS 8.0 及更高版本中可用。

参考UIModalPresentationStyle 参考

例如

ModalViewController *modal = [[ModalViewController alloc] init];
modal.modalPresentationStyle = UIModalPresentationPopover;
modal.transitioningDelegate = self;
modal.popoverPresentationController.sourceView = self.view;
modal.popoverPresentationController.sourceRect = CGRectZero;
modal.popoverPresentationController.delegate = self;

[self presentViewController:modal animated:YES completion:nil];

否则使用 UIPopoverPresentationController

例如

UIPopoverPresentationController *popController = [self. popoverPresentationController];
popController.permittedArrowDirections = UIPopoverArrowDirectionAny;
popController.barButtonItem = self.leftButton;
popController.delegate = self;
