Our popular drawing/painting application, InkPaint, has been updated to version 1.6 today.

The new version contains an important fix for problem on iOS 6 that would cause it to abruptly exit.

Also, if you're running on iOS 6, we now use Apple's new standard sharing dialog to share your drawings via Facebook, Twitter, email, etc., as well as copy them to the clipboard or send them to your network printer.

The new update is recommended for all InkPaint users.  And if you're not using InkPaint already, please check it out — we are sure you will love how easy and fast it is to create professional-quality drawings.

We've had a lot of rather philosophical blog posts lately (mostly related to the BOSS text searching system). It seems time to put that aside a moment and get back to some nice, solid iOS coding.

A common pattern for iPhone apps is a tab bar on the bottom, with a navigation stack on each tab. Today, we'll look at how to set up such a structure in code.  (And we'll do it in pure, unsweetened Cocoa for that nostalgic old-school feel.)

Last week, we presented a method for playing videos that supports external monitors (like the Apple VGA Adapter). But we left out a few finishing touches.

We have a client project that, at several points in the iPad app, displays videos that were embedded into the app. This is an older app, originally written before there were such things as iPad VGA adapters. One might hope that, in the absence of any programming directives telling it otherwise, the iPad would simply mirror its entire display to the video port. Failing that (as Apple in fact has done), you might hope that the MPMoviePlayerController would automatically support the external display. But that fails too.
