IOS 7锁定屏幕Objective-C的警报本地通知

Question

我正在练习在 IOS 7 上开发警报应用程序，例如警报。 Alarm time up on IOS7 但是，我在锁定屏幕时停留在本地通知，就像这样。 My notification 我做的一些代码：

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];
}

谁能帮忙？

谢谢

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。如果您想添加一个 API 来获得全屏警报样式，您可以尝试filing an enhancement request。

 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;
}

并在 View Controller.m 中调用这个函数

- (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];

}
