Hi all: I have recently started creating an iPhone application using Appcelerator's Titanium. Since the application is essentially all JS, I needed some advice on how I should organize this project. It's becoming very easy to just create long procedural files for each view in the application. Is there a way I can incorporate MVC, or so...

I have a bit of a strange problem. I am trying to send in-app email. I am also using Cocos2d. It works, so far as I get the mail window and I can send mail, but it is extremely slow.

Do older iPods and iPhones have a frame rate of 60fps? I'm finding that all the methods for calculating time intervals on iPhone (cftimeinterval, nstimer, timesince1970, etc) are all giving me bad data, so I've decided assume a frame rate of 60, just not sure if older apple devices can run at this. ...

I want to display a popup image over a given UIView, but I would like it to behave like the UIAlertView or like the Facebook Connect for iPhone modal popup window, in that it has a bouncy, rubbber-band-like animation to it.

I'm considering upgrade SDK 3.1.3 to 3.2 because 3.1.3 disappeared on Apple's website. I used 3.2 SDK beta once, and any project launched iPad simulator only.

I thought the following might work, but it just returns the symbol as $: currencyCode = [dictPri...
