  1. POImage getting pixelated when used as part of an animation in iPhone animation
    text
    copied!<p>After countless tries I got my animation animating right (Why oh why is the layer's coordinate system Y flipped from the view's coordinate system, I will never guess) but it seems that it degrades the image quality for some reason:</p> <p><img src="https://imgur.com/PZOR0.png" alt=""></p> <p>(green circled are examples of the original good quality images, the red circled is to emphasize the difference. <a href="https://imgur.com/PZOR0.png" rel="nofollow noreferrer">original image.</a>).</p> <p>Close up:</p> <p><img src="https://imgur.com/kq5L6.png" alt="alt text"></p> <p>(The lower images are as supposed to be, except the left one. The rest are pixelated.)</p> <p>The code I'm using (approximately, you can see the exact one in the image.):</p> <pre><code>CGImageRef *ir = [UIImage imageNamed:@"something"].CGImage; CALayer *cl = [CALayer layer]; cl.contents = ir; CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"transform.translation.x"]; anim.duration = 5; anim.autoreverses = NO; anim.removedOnCompletion = NO; anim.fromValue = **something** anim.toValue = **anotherthing** [cl addAnimation:anim forKey: @"fallDown"]; </code></pre> <p>My questions:</p> <ol> <li><p>Why is there such a difference between the images? How do I fix it?</p></li> <li><p>How is my code? I just can't find enough examples / explanations about the animation types and all stuff you can do with it (for example all of the animatable properties). And I am learning the SDK by myself (I have iPhone in Action but it's quite basic) and there is no one I know to review my code :)</p></li> </ol>
