Answer 1

UIView *view = // your view    
UIGraphicsBeginImageContext(view.bounds.size);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

This gives the image which you can store using –

NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
[imageData writeToFile:path atomically:YES];

where path is location you want to save to.
