localNotif.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
}
您可以为特定的timstamp设置本地通知。
您必须在ApplicationIDFinishedLaunching中检查用户信息字典,以获取任何通知数据
你必须处理:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
只需将firedate指定为UIDatePicker中的日期,将NSDayCalendarUnit指定为repeatinterval:
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = datePicker.date;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = @"This is the Alert-Body Text"];
localNotif.alertAction = @"Button-Text";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
localNotif.repeatInterval = NSDayCalendarUnit;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
