ios本地推送方法

//
创建一个本地推送

UILocalNotification
*notification = [[[UILocalNotification alloc] init] autorelease];

//设置10秒之后

NSDate
*pushDate = [NSDate dateWithTimeIntervalSinceNow:10];

if

(notification
!= nil) {

//
设置推送时间

notification.fireDate
= pushDate;

//
设置时区

notification.timeZone
= [NSTimeZone defaultTimeZone];

//
设置重复间隔

notification.repeatInterval
= kCFCalendarUnitDay;

//
推送声音

notification.soundName
= UILocalNotificationDefaultSoundName;

//
推送内容

notification.alertBody
= @

"推送内容"

;

//显示在icon上的红色圈中的数子

notification.applicationIconBadgeNumber
= 1;

//设置userinfo
方便在之后需要撤销的时候使用

NSDictionary
*info = [NSDictionary dictionaryWithObject:@

"name"

forKey:@

"key"

];

notification.userInfo
= info;

//添加推送到UIApplication

UIApplication
*app = [UIApplication sharedApplication];

[app
scheduleLocalNotification:notification];

}

//声明本地通知对象

UILocalNotification
