Quick Code: URL Encoding – mailto example
Ever notice that when you go to a website there are some strange percent sign things going on up in the address bar? Well that’s URL encoding. You are probably most familiar with %20. That’s a space. When typing out Objective-C code, if you need a URL encoded string (maybe for a GET request), there

For those that love cocos2d as much as I do, you know that basically everything is a subclass of CCNode. Position is a the location in points (not pixels) of a CCNode where (0,0) is the bottom left corner of the parent object. Once you get into writing cocos2d apps, you will find that you

Today’s quick code is about using CCLayerColor and CCLayerGradient. These two objects are very useful for one, because of their simplicity, and for two, they keep you from making new sprite objects. Before I knew these objects existed, I would create a solid color 480×360 and 960×720 solid color image to use as a background

Awesome little bit of code here. Any time you want a bit of code to run in the future, you can schedule it to run after a number of seconds delay. For this you use performSelector:withObject:afterDelay:. It really works just as simple as it looks. Here’s a quick example: [mySprite performSelector:@selector(setVisible:) withObject:[NSNumber numberWithBool:YES] afterDelay:2.0f]; This
