ios 8交互式通知未显示操作

问题描述

这是我为ios8注册交互式通知的代码：

This is my code to register Interactive Notifications for ios8 :

+ (void)registerInteractiveNotifications
{
    UIMutableUserNotificationCategory *corideInviteCategory = [self corideInviteCategory];
    UIMutableUserNotificationCategory *riderInviteCategory = [self riderInviteCategory];

    NSSet *categories = [NSSet setWithObjects:corideInviteCategory, riderInviteCategory, nil];
    UIUserNotificationType types = (UIUserNotificationTypeAlert|
                                    UIUserNotificationTypeSound|
                                    UIUserNotificationTypeBadge);

    UIUserNotificationSettings *settings;
    settings = [UIUserNotificationSettings settingsForTypes:types
                                                 categories:categories];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}

+ (UIMutableUserNotificationCategory *)riderInviteCategory
{
    UIMutableUserNotificationAction *accept;
    accept = [[UIMutableUserNotificationAction alloc] init];
    [accept setActivationMode:UIUserNotificationActivationModeForeground];
    [accept setTitle:@"Accept"];
    [accept setIdentifier:RiderInviteAccept];
    [accept setDestructive:NO];
    [accept setAuthenticationRequired:NO];

    UIMutableUserNotificationAction *decline;
    decline = [[UIMutableUserNotificationAction alloc] init];
    [decline setActivationMode:UIUserNotificationActivationModeForeground];
    [decline setTitle:@"Decline"];
    [decline setIdentifier:RiderInviteDecline];
    [decline setDestructive:YES];
    [decline setAuthenticationRequired:NO];

    UIMutableUserNotificationCategory *actionCategory;
    actionCategory = [[UIMutableUserNotificationCategory alloc] init];
    [actionCategory setIdentifier:RiderInviteCategory];
    [actionCategory setActions:@[decline, accept]
                    forContext:UIUserNotificationActionContextDefault];
    [actionCategory setActions:@[decline, accept] forContext:UIUserNotificationActionContextMinimal];

    return actionCategory;
}

+ (UIMutableUserNotificationCategory *)corideInviteCategory
{
    UIMutableUserNotificationAction *accept;
    accept = [[UIMutableUserNotificationAction alloc] init];
    [accept setActivationMode:UIUserNotificationActivationModeForeground];
    [accept setTitle:@"Accept"];
    [accept setIdentifier:CorideInviteAccept];
    [accept setDestructive:NO];
    [accept setAuthenticationRequired:NO];

    UIMutableUserNotificationAction *decline;
    decline = [[UIMutableUserNotificationAction alloc] init];
    [decline setActivationMode:UIUserNotificationActivationModeForeground];
    [decline setTitle:@"Decline"];
    [decline setIdentifier:CorideInviteDecline];
    [decline setDestructive:YES];
    [decline setAuthenticationRequired:NO];

    UIMutableUserNotificationCategory *actionCategory;
    actionCategory = [[UIMutableUserNotificationCategory alloc] init];
    [actionCategory setIdentifier:CorideInviteCategory];
    [actionCategory setActions:@[decline, accept]
                    forContext:UIUserNotificationActionContextDefault];
    [actionCategory setActions:@[decline, accept] forContext:UIUserNotificationActionContextMinimal];

    return actionCategory;
}

当我删除应用并再次安装时，会发生以下情况：按钮（当我拉下通知横幅，或在通知中心向左滑动时）出现。但过了一段时间（我不确定是什么导致它），虽然我不断发送相同的通知，但它们仍然停止出现。这是我的通知内容：

What happens is : when i delete the app and install again, the 2 action buttons (when I pull down the notification banner, or swipe left in notification center) appears. But after a while ( i'm not really sure what cause it ), they stop appearing although i keep sending the same notification. This is my notification content:

{"aps":{"alert":"test","category":"coride_invite"},"journey_id":100}

有人可以解决一些问题吗？谢谢

Can anyone shed some light please ? Thanks

推荐答案

如果代码中还有其他地方，请检查以下代码：

Check for the following in you code if it is anywhere else as well:

 [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

因为， UIUserNotificationSettings 是单身，无论何时你这个叫它，它会覆盖旧的设置。因此，如果在没有任何按钮的情况下注册新设置，则不会显示任何按钮。

Since, UIUserNotificationSettings is singleton, whenever you call this, it overwrites the old settings. So if new settings is registered without any buttons it will not show any buttons.

此处说明了更好的注册新设置的方法：

Better way of registering new setting is explained here:Interactive push notifications - Hide/Show buttons
