ios - UIPopoverController 不关闭

Question

我有一个普通的 UIPopoverController，它是这样制作的:

-(IBAction)btKBIs_click:(id)sender
{

if(kbiPopOver != NULL)
    [kbiPopOver dismissPopoverAnimated:YES];

KBIViewController *kbiViewController = [[KBIViewController alloc]initWithNibName:@"KBIViewController" bundle:nil CurrentUser:currentUser];
kbiViewController.currentStatus = FIRST;
kbiViewController.firstlist = [currentUser getDescriptions];
kbiViewController.mapViewController =self;


UINavigationController* kbiNavController = [[UINavigationController alloc] initWithRootViewController:kbiViewController];

kbiPopOver = [[UIPopoverController alloc] initWithContentViewController:kbiNavController];
kbiPopOver.delegate = self;

kbiViewController.kbiPopOver = kbiPopOver;

[kbiPopOver presentPopoverFromBarButtonItem:sender 
                     permittedArrowDirections:UIPopoverArrowDirectionUp animated:true];

}

在我调用的 KBIViewController 类中:

    [self.kbiPopOver dismissPopoverAnimated:YES];
    [self.kbiPopOver.delegate popoverControllerDidDismissPopover:self.kbiPopOver];

要关闭它，但它不起作用。为什么？

您是否添加了 <UIPopOverControllerDelegate>在你的类界面中，你是否实现了– popoverControllerDidDismissPopover:方法？只需调用 dismissPopoverAnimated:当您在弹出窗口外点击时，在您的代码或委托(delegate)方法中显式显示。删除 [self.kbiPopOver.delegate popoverControllerDidDismissPopover:self.kbiPopOver];来自您的代码。
