I was so excited that I tweeted the shipping notification to sarcastically note the availability in June still.</p><figure><img src="2015-04-22_11-02-33.png" class="kg-image" alt="Screen capture of the Preparing Shipment notification with a note of the watch being available in June" loading="lazy" width="660" height="183"></figure><p>Copying that text into a tweet, I actually got:</p><p>Preparing for Shipment TODO: Pull info bubble content div up to the order list level (only need 1 per page) and refactor info bubbles into single conditional &amp; span based on group status type OR alternatively, refactor to single info bubble per delivery group based on status shipped shipped Available to ship: June</p>https://aaron.blog/nsnotificationcenter-block-based-observer-2/Tue, 17 Dec 2013 15:22:37 +0000https://aaron.blog/nsnotificationcenter-block-based-observer-2/<p>Back in iOS 4, a nifty block-based observer method was added to NSNotificationCenter:<br></p><ul><li><code>(id)addObserverForName:(NSString *)name object:(id)obj queue:(NSOperationQueue *)queue usingBlock:(void (^)(NSNotification *))block;</code><br></li></ul><p>Super convenient, right? I love using blocks to pass simple callbacks to controllers instead of creating a delegate protocol. There is a catch with this method, and it's not terribly obvious unless you're looking closely. The method returns (id) - according to Apple's documentation the return object is "An opaque object to act as the observer".  What does this mean?</p>
