// 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];
}

- ( void )application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@ "iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@ "确定" otherButtonTitles:nil];
[alert show];
// 图标上的数字减1
application.applicationIconBadgeNumber -= 1;
}

// 获得 UIApplication
UIApplication *app = [UIApplication sharedApplication];
//获取本地推送数组
NSArray *localArray = [app scheduledLocalNotifications];
//声明本地通知对象
UILocalNotification *localNotification;
if (localArray) {
for (UILocalNotification *noti in localArray) {
NSDictionary *dict = noti.userInfo;
if (dict) {
NSString *inKey = [dict objectForKey:@ "key" ];
if ([inKey isEqualToString:@ "对应的key值" ]) {
if (localNotification){
[localNotification release];
localNotification = nil;
}
localNotification = [noti retain];
break ;
}
}
}
//判断是否找到已经存在的相同key的推送
if (!localNotification) {
//不存在初始化
localNotification = [[UILocalNotification alloc] init];
}
if (localNotification) {
//不推送 取消推送
[app cancelLocalNotification:localNotification];
[localNotification release];
return ;
}
}
