UIImage *image = [UIImage imageNamed:@"some_image.png"];
CGImageRef tmpImgRef = image.CGImage;

//Taking left part of image from 0 to half of width
CGImageRef leftImgRef = CGImageCreateWithImageInRect(tmpImgRef, CGRectMake(0, 0, image.size.width/2.0, image.size.height ));
UIImage *leftUIImage = [UIImage imageWithCGImage:leftImgRef];
CGImageRelease(leftImgRef);

//Taking right of image from half of width to full width
CGImageRef rightImgRef = CGImageCreateWithImageInRect(tmpImgRef, CGRectMake(image.size.width / 2.0, 0, image.size.width/2.0, image.size.height));
UIImage *rightUIImage = [UIImage imageWithCGImage:rightImgRef];
CGImageRelease(rightImgRef);

//Placing images into separated containers (UIImageView) in order to manipulate with them
[_leftImage setImage:leftUIImage];
[_rightImage setImage:rightUIImage];
