Question

我正在练习在IOS 7上开发Alarm应用程序。 Alarm time up on IOS7 但是，我在锁定屏幕上停留在本地通知，就像这样。 My notification 我做了一些代码：

在我的AppDelegate.m

中

我的代码

[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];

    // Handle launching from a notification
    UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

....
..in my ViewController.m..

[self scheduleLocalNotificationWithDate:correctDate];
....
(void)scheduleLocalNotificationWithDate:(NSDate *)fireDate {

    UILocalNotification *localNotification = [[UILocalNotification alloc] init];

    localNotification.fireDate = fireDate;
    localNotification.alertBody = [NSString stringWithFormat:@"Alert Fired at %@", fireDate];
    localNotification.soundName = UILocalNotificationDefaultSoundName;

    localNotification.applicationIconBadgeNumber = numberReminder;
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

谁可以帮忙做到这一点？

Answer 1

第三方应用程序不会像系统闹钟应用程序那样出现在锁定屏幕上 - 您的应用程序只能生成普通通知。如果您希望添加API以获得全屏提醒样式，则可以尝试filing an enhancement request。

Answer 2

 if([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]) {
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
}

UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

if(notification) {       
    application.applicationIconBadgeNumber = 0;
}

在View Controller.m中调用此函数

- (void) Notify {
NSDate *fireDate = [[NSDate alloc]init];
fireDate = self.datePicker.date;    

NSCalendar *cal = [NSCalendar currentCalendar];
NSDateComponents *dateComp = [cal components:(NSCalendarUnitHour | NSCalendarUnitMinute| NSCalendarUnitSecond) fromDate:fireDate];    

NSDate *dd = [cal dateByAddingComponents:dateComp toDate:fireDate options:0];    

UILocalNotification *notification = [[UILocalNotification alloc]init];
[notification setFireDate:dd]; 
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

}
