I'm crossfading between two views using UIView animation. I've noticed the following surprising fact: If I have (say) two identical views in an identical place, and I animate a cross fade between them (e.g. animate the alpha from 0.0 to 1.0 on one while going from 1.0 to 0.0 on the other, in the same animation), during the animation, th...
Hi All, I'm currently writing an iPhone app where I need to uncompress several files from .pak archive.

Any help at all would be much appreciated...

I am setting the frame property of a UIImageView at a frequency of about 30Hz. Instruments shows that QuartsCore is allocating (and releasing) 88 bytes at this frequency.

Hey all, I'm getting tired of creating free apps that are of a high quality, but they don't do much for me. I looked into selling paid apps and iAds, but they both require the intervention of the tax man, who I really don't want to get into trouble with. What is the best thing I can do, as a 16-year-old developer, to monetize my iPhone...
Hi! I've been doing some tests, and one of my needs is to read data from different xml files and stack it together on a single file. While I've managed to accomplish this, memory consumption seems to be quite large for the task, the iphone simulator didn't even raise the memory warning, but I don't think the real iPhone would tolerate th...

However, it is happily parsed by NSURL with no errors at all. It does not return nil and it does not throw an exception. Calling [url absoluteS...
