Weekly Roundup

by Aaron Brethorst | February 27, 2012

Hello everyone, and welcome to your weekly Cocoa Controls roundup! It’s been an exciting week for Mac developers with the unexpected announcement and Beta release of OS X Mountain Lion. Some of the new features, like Gatekeeper, are certainly not unexpected. This Cocoa developer, for one, is pleased that Apple has announced a reasonably middle-of-the-road approach that balances security with usability.

Perhaps one of the biggest surprises in Mountain Lion is what Apple did not announce: Siri. The existence of the feature for iOS was a poorly guarded feature up until the announcement of the iPhone 4S. It’s possible Apple is simply biding its time until WWDC. We’ll see.

Until next time,

Aaron

SJNotificationViewController

Notifications slide up from the bottom of whatever view they’re attached to and slide back down when you or the user are done with them. Great for indicating that something is happening (a feed is being refreshed, for example) or that something has just happened (there was an error sending something, for example) without throwing up a UIAlertView.

You can customize the notification text, the notification level (which affects the background color of the notification — red for error, blue for message, and green for success), the target/selector that’s fired when the user taps the notification, and whether or not the notification has a spinner. BSD licensed.

JTGestureBasedTableViewDemo

Next up is our super-duper cool Control of the Week. If you’ve paid any attention to Mac or iOS news websites over the past week or two, you’ve probably heard a lot of people talking about the super-snazzy task management app, Clear.

Enterprising iOS developer, James Tang, recreated the core experience and released the source code on GitHub under the very permissive MIT license.
