Add new 'appearance' optional block, constructors to enable proper syncing of sound/vibration with queued notifications.

[andyzei]

CRToast automatically handles notification queuing, which is great -- it's essentially fire-and-forget. Currently, there is an optional block that you can provide to be called after a notification shows. Unfortunately, there isn't a way to get notified when a notification is actually being shown.

The scenario here is that several notifications are queued to show, and you want to play a sound / vibration each time a notification is dequeued/shown.

This change simply adds an additional block property to CRToast, and a new constructor that lets the caller provide it. The block is called immediately before the notification is shown.

I did my best to emulate the project formatting / conventions -- if you have feedback, I'm happy to do an iteration or two. Thanks for providing this library -- it's really great.

Thanks,

Andy

Great work Andy. Thanks.

This is great but I don't think showBegin is a very good name. I was thinking appearanceBlock? Also I would want the signature to be

+ (void)showNotificationWithOptions:(NSDictionary*)options appearanceBlock:(void (^)(void))appearanceBlock completionBlock:(void (^)(void))completion;

rather than

+ (void)showNotificationWithOptions:(NSDictionary*)options completionBlock:(void (^)(void))completion showBeginBlock:(void (^)(void))showBegin;

Thoughts?

@cruffenach -- great feedback -- agreed completely. Lemme spin up a change....

[andyzei]

@cruffenach, all fixed -- lemme know if you have any additional feedback / concerns -- thanks again for taking a look at this!

Should be if (notification.appearance) notification.appearance();

[andyzei]

indeed -- will fix -- sorry I missed this

[Ashton-W]

I wonder if appearance is confusing with UIAppearance :)

[cruffenach]

I hear you @Ashton-W, don't think its too big a deal myself. Other suggestions?

[Ashton-W]

Nah, looks great

[andyzei]

woot

[cruffenach]

Can we get this resolved?

[andyzei]

@cruffenach -- wow can't belive I missed that -- thanks. Fixed

[andyzei]

You guys rock -- thank you so much!
