1.建立開關如圖操作

2.開關為OFF

3.拖拽後Connection選擇Action

4.Type選擇UISwitch

5.ViewController中點選開關按鈕

if(sender.on == YES){
        UILocalNotification *local=[[UILocalNotification alloc]init];
        //設定通知的標題
        [email protected]"本地推送Demo傳送的本地通知";
        [email protected]"您的s護衛艦已經升級完畢趕快去攻城";
        local.applicationIconBadgeNumber=2;
        
 
[email protected]{
                         @"name":@"武則天",
                         @"age":@"1000",
                         @"sex":@"男"
                         };
        //設定一個觸發時間
        local.fireDate=[NSDate dateWithTimeIntervalSinceNow:5];
        //讓應用程式類物件去傳送本地通知
        [[UIApplication sharedApplication]scheduleLocalNotification:local];
        //申請使用者授權
        
    }
 

6.在AppDelegate中

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 申請使用者的推送授權
    // 申請使用者的推送授權
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert categories:nil];
    [[UIApplication sharedApplication]registerUserNotificationSettings:settings];
    return YES;
}
//申請使用者推送授權的回撥方法
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
    
}
//收到本地推送的回撥方法

    //s接到資訊字典,並列印
    for(NSString *key in notification.userInfo){
        NSLog(@"%@:%@",key,notification.userInfo[key]);
    }
    //把角標去除
    application.applicationIconBadgeNumber=0;
}

- (void)applicationWillResignActive:(UIApplication *)application {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}


- (void)applicationDidEnterBackground:(UIApplication *)application {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}


- (void)applicationWillEnterForeground:(UIApplication *)application {
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}


- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}


- (void)applicationWillTerminate:(UIApplication *)application {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    // Saves changes in the application's managed object context before the application terminates.
    [self saveContext];
}
