In this post I will show a good way to resize UIImage, add shadow, corner radius and still have smooth movement of the image.
[css]
UIImage *image = [UIImage imageNamed:@"image.png"];
// Begin a new image that will be the new image with the rounded corners
// (here with the size of an UIImageView)
UIGraphicsBeginImageContextWithOptions(image.size, NO, [UIScreen mainScreen].scale);
// Add a clip before drawing anything, in the shape of an rounded rect
[[UIBezierPath bezierPathWithRoundedRect:CGRectMake(0, 0, image.size.width, image.size.height)
cornerRadius:10.0] addClip];
// Draw your image
[image drawInRect:imageView.bounds];
// Get the image
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
// Lets forget about that we were drawing
UIGraphicsEndImageContext();
[/css]
