本地推送

1.创建开关如图操作

2.开关为OFF

3.拖拽后Connection选择Action

4.Type选择UISwitch

5.ViewController中点击开关按钮

if(sender.on == YES){
        UILocalNotification *local=[[UILocalNotification alloc]init];
        //设置通知的标题
        local.alertTitle=@"本地推送Demo发送的本地通知";
        local.alertBody=@"您的s护卫舰已经升级完毕赶快去攻城";
        local.applicationIconBadgeNumber=2;
        local.userInfo=@{
                         @"name":@"武则天",
                         @"age":@"1000",
                         @"sex":@"男"
                         };
        //设置一个触发时间
        local.fireDate=[NSDate dateWithTimeIntervalSinceNow:5];
        //让应用程序类对象去发送本地通知
        [[UIApplication sharedApplication]scheduleLocalNotification:local];
        //申请用户授权
        
    }

6.在AppDelegate中

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

    // 申请用户的推送授权
    // 申请用户的推送授权

    return YES;
}

    }
    //把角标去除
    application.applicationIconBadgeNumber=0;
}

}

}

}

}

    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
