So I'm trying to animate an image stretching from a zero width to full size while fading in. The fade in comes across fine, but for whatever reason the thing appears at the full frame at the start of the animation, instead of growing as the alpha effect happens. My code is as follows: [UIView beginAnimations:@"FadeButtons" context:nil];...

There appears to be a mysterious padding added to the left of ALL <li> elements on the page (almost like a padding-left:30px) when viewing the webpage over 3G/Edge/GPRS. However, when viewing the page over wifi, the padding disappears, and the page ren...

Here are the UIActionS...

I have a program that, at present, uses both UIImage and CGImage components. There's one CGImage tucked away in there for use as an image mask, since it seems easier to create the mask as a CGImage and leave it that way than to tuck it into the UIImage wrapper. My question is simply: are there any tangible differences between using a UII...
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...

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...

So far, I've taken a cursory look at Netem and ns-2 (or its offspring ns-3). Nete...
