I just figured out that - instead of using a UIImageView to show an image - I use an UIWebView, it uses much less memory. Does that make sense for anyone? What I did was to get an ordinary .jpg file with about 280kb in size and show it on a simple app with just an UIImageView. Looking at Instrument's Object Allocations tool, the applic...

As many people are complaining it seems that in the Apple SDK for the Retina Display there's a bug and imageWithContentsOfFile actually does not automatically load the 2x images. I've stumbled into a nice post how to make a function which detects UIScreen scale factor and properly loads low or high res images ( http://atastypixel.com/bl...

Hey guys, I have a little issue here; my goal is to be able to process images at a very fast rate, maybe up to 10 images per second. What is happening is I'm getting a CGImage, converting it to UIImage, and saving it to disk. But I'm realizing that saving using writeToFile is quite "slow", as I need to be able to save ten of these per s...
Hello everyone! So, I'm actually making an iPhone app with a big library of guitar chords and scales. The scales are logical, so they are successfully draw by following musical theory. On the other hand, I have a library of 4500 small png files (3ko) for the guitar chords. My problem is that even if it's not used for the launch (but f...
For example, the png file is 1200 (h) x 50 (w) pixels, how can I cut the png and loads in 6 UIImages, each 200 (h) x 50 (w). Thanks!
