Ever had issues with your CoreGraphics image masks just refusing to work right? Yeah, us too. But here’s a tip on how to make them reliable:

…Thus, I’ve found that the best and most reliable way to generate an image mask from an arbitrary image is to do this:

  1. Create a bitmap graphics context that is in an acceptable format for image masks
  2. Draw your image into this bitmap graphics context
  3. Create the image mask from the bits of the bitmap graphics context…

… The challenge for any content publisher therefore, is how to support their users in finding the content that they are looking for.

Locayta Search Mobile solves this problem by providing highly accurate and relevant search results, enabling users to find exactly ...

Wireless Ad Hoc Distribution

So a while back there was this article drawing our attention to the fact that the description here

Installing Applications and Distribution Provisioning Profiles Wirelessly

iOS 4 supports over-the-air installation of enterprise applications, allowing you to distribute in-house software to your iPhone and iPod touch users without having to use iTunes or iPhone Configuration Utility…

is not, in fact, limited to enterprise applications; any ad hoc application can be distributed this way. Long as they’ve upgraded to iOS 4, and so ...

AppStore Review Links Redux

If you’ve been including direct review links in your apps — personally, we’ve found the itms-apps:// URL scheme described here to be the most reliable for that — here’s a subtlety for iPad-only apps that may have escaped you:

… The above link takes you directly to the review page, which is one layer down below the main app description page on the iPhone. If you have an iPhone-only, or a universal app, this link will also work on ...

So, looks like there’s a new App Store alternative around these days: OpenAppMkt! Basically they’re doing their best to replicate the App Store experience with HTML5 apps; and they seem to be getting a little bit of traction. As well as a good deal of frenzied yammering about “loopholes” and the like, from people whose memories apparently are not good enough to extend back to 2007 when we were all being told that HTML5 would be the only way ...

My, it’s been a while since the last time we had a new trollish trifle for you to try, isn’t it? Our recent projects do just seem to be wandering off into the weeds in every direction, cha. But hey, here’s one today; yet another in the ever expanding collection of trinkets for those great Wayz guys, it’s … iGoalKeeper!
