在iOS实现本地通知这篇文章中，介绍了通知的定义和最简单的实现。下面我将介绍一个比较复杂一点的例子，实现的效果如下：
开启通知。
通知的内容。
通知的次数。
下面是具体的实现：
首先是通知次数取消：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. / application.applicationIconBadgeNumber = 0; // Add the view controller’s view to the window and display. [self.window addSubview:viewController.view]; [self.window makeKeyAndVisible];
return YES; }
通知的具体实现：
#pragma mark – #pragma mark onChageValue -(IBAction)onChangeValue:(id)sender { UISwitch *switch1=(UISwitch *)sender; if (switch1.on) { UILocalNotification *notification=[[UILocalNotification alloc] init]; NSDate *now1=[NSDate date]; notification.timeZone=[NSTimeZone defaultTimeZone]; notification.repeatInterval=NSDayCalendarUnit; notification.applicationIconBadgeNumber = 1; notification.alertAction = NSLocalizedString(@"显示", nil); switch (switch1.tag) { case 0: { notification.fireDate=[now1 dateByAddingTimeInterval:10]; notification.alertBody=self.myLable1.text; } break; case 1: { notification.fireDate=[now1 dateByAddingTimeInterval:20]; notification.alertBody=self.myLable2.text; } break; case 2: { notification.fireDate=[now1 dateByAddingTimeInterval:30]; notification.alertBody=self.myLable3.text; } break; default: break; } [notification setSoundName:UILocalNotificationDefaultSoundName]; NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: [NSString stringWithFormat:@"%d",switch1.tag], @"key1", nil]; [notification setUserInfo:dict]; [[UIApplication sharedApplication] scheduleLocalNotification:notification]; }else { NSArray *myArray=[[UIApplication sharedApplication] scheduledLocalNotifications]; for (int i=0; i<[myArray count]; i++) { UILocalNotification *myUILocalNotification=[myArray objectAtIndex:i]; if ([[[myUILocalNotification userInfo] objectForKey:@"key1"] intValue]==switch1.tag) { [[UIApplication sharedApplication] cancelLocalNotification:myUILocalNotification]; } } } }
