HD footage at that framerate would be incredibly useful for capturing the banal and everyday surroundings of life in a new way.  I’d really like to capture some macro depth-of-field moments with the subtle motion in the background.

Throwing Image Data into Arrays, Sets, Dictionaries

There are multiple ways of drawing image data out, but this way draws directly into a graphics context, which is good for doing procedural animation (ala processing/computational visualization)

//throwing it in from jpg in resources folder
UIImage *myImage = [UIImage imageWithContentsOfFile:@"myImage.jpg"];
NSArray *myArray = [NSMutableArray array]; // this will autorelease
[myArray addObject:myImage];

//drawing back out
CGContextRef context = UIGraphicsGetCurrentContext(); // get GC
UIImage *myImage = [myArray lastObject];
CGImageRef *myCGImage = [myImage CGImage];
CGContextDrawImage(context, rect, myCGImage);

Converting JPEG/PNG Images in NSImage into NSData

NSData *imageData = UIImagePNGRepresentation(image); // png

NSData *imageData = UIImagePNGRepresentation(image); // jpg/jpeg

Grabbing a quick URL's data for (for quick API calls)

NSString *text = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"]];
if(text){
textView.text = text;
}
