ios – 检测popover dismiss

概述我想玩UIPopupController,我明白我无法检测到我的popover何时解雇. 我的步骤： 1.从XCode创建示例(文件 – >新项目 – >实用应用程序) 2.添加到MainViewController.h UIPopoverControllerDelegate #import "FlipsideViewController.h"@interface MainViewContro 我想玩UIPopupController,我明白我无法检测到我的popover何时解雇.
我的步骤：
1.从XCode创建示例(文件 – >新项目 – >实用应用程序)
2.添加到MainVIEwController.h UIPopoverControllerDelegate

#import "FlipsIDeVIEwController.h"@interface MainVIEwController : UIVIEwController <FlipsIDeVIEwControllerDelegate,UIPopoverControllerDelegate>@property (strong,nonatomic) UIPopoverController *flipsIDePopoverController;- (IBAction)showInfo:(ID)sender;@end

>在MainVIEwController中：

    - (IBAction)showInfo:(ID)sender    {        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {            FlipsIDeVIEwController *controller = [[FlipsIDeVIEwController alloc] initWithNibname:@"FlipsIDeVIEwController" bundle:nil];            controller.delegate = self;            controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;            [self presentModalVIEwController:controller animated:YES];        } else {            if (!self.flipsIDePopoverController) {                FlipsIDeVIEwController *controller = [[FlipsIDeVIEwController alloc] initWithNibname:@"FlipsIDeVIEwController" bundle:nil];                controller.delegate = self;                self.flipsIDePopoverController.delegate = self                self.flipsIDePopoverController = [[UIPopoverController alloc] initWithContentVIEwController:controller];            }            if ([self.flipsIDePopoverController isPopoverVisible]) {                [self.flipsIDePopoverController dismisspopoverAnimated:YES];            } else {                [self.flipsIDePopoverController presentPopoverFrombarbuttonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];            }        }    }    -(voID)popoverControllerDIDdismisspopover:(UIPopoverController *)popoverController    {        NSLog(@"ololO");    }

但是当我点击某个地方,并且popover消失时,Console中没有NSLog消息.
我究竟做错了什么？

解决方法 将popover的代表设置为self,你也可以使用两个popover代理,即： –

/* Called on the delegate when the popover controller will dismiss the popover. Return NO to prevent the dismissal of the vIEw. */- (BOol)popoverControllerShoulddismisspopover:(UIPopoverController *)popoverController;/* Called on the delegate when the user has taken action to dismiss the popover. This is not called when -dismisspopoverAnimated: is called directly. */- (voID)popoverControllerDIDdismisspopover:(UIPopoverController *)popoverController;
