More animation transitions for iOS
I think that one of the most common deceptions for iOS developers is to discover how small is the set of default transitions that the iOS SDK support out of the box. There are just four of them: flip from left or right, and curl up or down. Well, I also think that all iOS developers also think that those four are simply the only <i>public</i> transitions in the SDK, but that there have to be more. But, you know, non public means rejection, a word that no one likes.
Lately, thank to this post by Benjamin Godard, I have not only discovered that indeed there are more transitions, but that there is also a way to safely use them – i.e., without your app being rejected. On this page you can find a list of all the numerical constant values that are associated to several default transitions that are there for your to use. Using the numerical code should be App-Store-safe, since no symbol is involved.
Cocos2D and the new Retina iPad
The introduction of the new iPad, a.k.a Retina-iPad, or iPad 3, has made developing universal applications supporting all of iOS devices definitely more complex. This is mostly due to the requirement of providing artwork for 4 (four!) different resolutions:
Review: iPoe for the iPad/iPhone
As a follow up to this old post of mine about interactive books for the iPhone/iPad, I would like to mention a new entry in the field: iPoe.
cocos2d and the new retina iPad - take 2
I described in a previous post about cocos2d and the new retina iPad a quick solution to the problem of supporting higher-resolution images. The main objective of that work was to make easier re-building your app for submission on the App Store before you could possibly provide higher-resolution images for the new iPad. I mentioned anyway that that approach was just a quick hack and not a full answer to the need to provide 4 (four!) different versions for any of your artworks.
Blur effect for Cocos2D textures on retina displays
I have recently needed to blur a Cocos2d texture to simulate an “out-of-view-field” effect. As it usually happens, it had been already implemented under the name of AWTextureFilter by Manuel Martínez-Almeda, who made it available on github.
