本地推送

1.AppDelegate.m里

- (void)application:(UIApplication*)application didReceiveLocalNotification:(UILocalNotification*)notification{

//如果应用程序在前台，将应用程序图标上红色徽标中数字设为0

application.applicationIconBadgeNumber=0;

//使用UIAlertView显示本地通知的信息

[[[UIAlertViewalloc]initWithTitle:@"收到通知"

message:notification.alertBody

delegate:nilcancelButtonTitle:@"确定"otherButtonTitles:nil]show];

}

2.发送通知按钮实现方法

if([UIApplicationinstancesRespondToSelector:@selector(registerUserNotificationSettings:)])

{

[[UIApplicationsharedApplication]registerUserNotificationSettings:[UIUserNotificationSettingssettingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSoundcategories:nil]];

}

//创建本地通知对象

UILocalNotification*ln = [[UILocalNotificationalloc]init];

//1.设置通知的内容(如果此属性不设置是不会发送通知的)

ln.alertBody=@"小明,你妈叫你回家吃饭了!";

//2.设置通知触发的开始时间

ln.fireDate= [NSDatedateWithTimeIntervalSinceNow:10];

//3.设置重复通知的时间,间隔

ln.repeatInterval=kCFCalendarUnitMinute;

ln.timeZone= [NSTimeZonedefaultTimeZone];

//5.设置应用图标右上角的数字

ln.applicationIconBadgeNumber=3;

ln.hasAction=YES;

//6.设置点击推送通知进入界面的时候显示,加载图片

ln.alertLaunchImage=@"";

//8设置一些额外信息

ln.userInfo=@{@"QQ":@"55555",@"info":@"约了没"};

//让应用调度通知

[[UIApplicationsharedApplication]scheduleLocalNotification:ln];

3.取消发送通知

//获取所有处于调度中本地通知数组

NSArray*localArray = [[UIApplicationsharedApplication]scheduledLocalNotifications];

if(localArray)

{

for(UILocalNotification*notiinlocalArray)

{

NSDictionary*dict = noti.userInfo;

if(dict)

{

//如果找到要取消的通知

NSString*inKey = [dictobjectForKey:@"QQ"];

if([inKeyisEqualToString:@"55555"])

{

//取消调度该通知

[[UIApplicationsharedApplication]cancelLocalNotification:noti];//②

}

}

}

}
