ios9 - iOS9的UILocalNotification问题

从iOS9开始，本地通知无法正常运行。
有时用户会收到通知，有时则不会。我的通知每天重复一次。
知道是什么原因引起的问题吗？我看到了一些帖子，说明iOS9中存在一个错误，但是我不确定这就是原因。

这是一段代码:

    NSDate *alarmDate = [date dateByAddingTimeInterval:DEFAULT_SNOOZE_DURATION * i];
    UILocalNotification *localNotif = [[UILocalNotification alloc] init];
    localNotif.fireDate = alarmDate;
    localNotif.timeZone = nil;
    localNotif.alertBody = alertBody;

    localNotif.hasAction = YES;

    localNotif.applicationIconBadgeNumber = 1;
    localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.repeatInterval = NSCalendarUnitDay;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif]

谢谢你的帮助

最佳答案

在AppDelegate.m中编写以下代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.

[launchOptions valueForKey:UIApplicationLaunchOptionsLocalNotificationKey];

if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)])
{

    [application registerUserNotificationSettings:[UIUserNotificationSettings
                                                   settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|
                                                   UIUserNotificationTypeSound categories:nil]];
}

return YES;

}

还要在AppDeleagte.m中编写此代码

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIAlertView *notificationAlert = [[UIAlertView alloc] initWithTitle:@"Reminder"    message:notification.alertBody
                                                           delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

[notificationAlert show];

// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}

在您要实现本地通知的ViewController中编写以下代码。

例如:在这里我初始化UILocalNotification，它的触发日期是currentTime和5seconds间隔时间。

触发fire localNotification后，它将在您的屏幕上发出警报。

- (void)viewDidLoad
{
[super viewDidLoad];
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:5];
notification.repeatInterval = NSDayCalendarUnit;
notification.alertBody = @"This is local notification!";
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 10;


[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
