Buttons don't show on local interactive notification in iOS - ios

Question

I've been busting my head against the table al morning with this. I know it's been asked before, but I really don't understand what's the problem with my code.
Here's the code I use to register and send interactive notifications.
Thanks in advance.
#define kNotificationActionNo #"ActionKeyNo"
#define kNotificationActionYes #"ActionKeyYes"
#define kNotificationCategoryVendingMachine #"VendingMachineNotification"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[self registerForNotification];
...
}
+ (void)sendLocalNotification:(NSString*)message info:(NSDictionary*)infoDict {
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.alertBody = message;
localNotification.fireDate = [NSDate date];
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.category = kNotificationCategoryVendingMachine;
localNotification.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
- (void)registerForNotification {
UIMutableUserNotificationAction *action1;
action1 = [[UIMutableUserNotificationAction alloc] init];
[action1 setActivationMode:UIUserNotificationActivationModeBackground];
[action1 setTitle:NSLocalizedString(#"YES_LEGEND", nil)];
[action1 setIdentifier:kNotificationActionYes];
[action1 setDestructive:NO];
[action1 setAuthenticationRequired:NO];
UIMutableUserNotificationAction *action2;
action2 = [[UIMutableUserNotificationAction alloc] init];
[action2 setActivationMode:UIUserNotificationActivationModeBackground];
[action2 setTitle:NSLocalizedString(#"NO_LEGEND", nil)];
[action2 setIdentifier:kNotificationActionNo];
[action2 setDestructive:NO];
[action2 setAuthenticationRequired:NO];
UIMutableUserNotificationCategory *actionCategory;
actionCategory = [[UIMutableUserNotificationCategory alloc] init];
[actionCategory setIdentifier:kNotificationCategoryVendingMachine];
[actionCategory setActions:#[action1, action2]
forContext:UIUserNotificationActionContextDefault];
NSSet *categories = [NSSet setWithObject:actionCategory];
UIUserNotificationType types = (UIUserNotificationTypeAlert|
UIUserNotificationTypeSound|
UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings;
settings = [UIUserNotificationSettings settingsForTypes:types
categories:categories];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}

Well first things first,
I don't see you actually calling your sendLocalNotification method anywhere in your didFinishLaunchingWithOptions: method. You should call it to see if it actually fires, because aesthetically, you've done everything you should have done in order to set up a category-based notification. kudos, and well written for a newcomer to StackOverflow. Additionally, if you are calling it and you just simply omitted it from the question, then your problem probably lies in how you are setting your method. Right now it's a class method, if its intended or not I'm not sure, however, my point is, if it's not working, and the notifications are showing up, just not the category actions, then you should probably call it correctly or change it to an instance method.
See the difference between the two here
You are so close. You had everything set up properly and then swayed on the end. You should call your sendLocalNotification like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self sendLocalNotification:#"Estas cerca de una máquina expendedora. ¿Quieres realizar una compra?" info:#{#"type":#"near_vending"}];
}
And change your method to properly reflect what kind of method it is. I included a a link above to show you the difference. You will set it like this:
-(void)sendLocalNotification:
NOT
+(void)sendLocalNotification:
