CAGradientLayer不够流畅？

本文介绍了CAGradientLayer不够流畅？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在为我的 UIView 的每个背景做 CAGradientLayer ，但我遇到了一个小问题。渐变似乎不够平滑。颜色之间的过渡将呈现。你可以在这张图片中看到它。

I'm doing a CAGradientLayer for every background of my UIViews, but I have a small problem. The gradient doesn't seem that smooth enough. The transition between the colors are to present. You can see it in this picture.

这就是我在UIView初始化程序中实现此渐变的方法。

This is how I implemented this gradient in the initializer of my UIView.

CAGradientLayer *layer = [CAGradientLayer layer]; layer.colors = [NSArray arrayWithObjects: (id)[[UIColor darkKinepolisColor] CGColor], (id)[[UIColor lightKinepolisColor] CGColor], (id)[[UIColor lightKinepolisColor] CGColor], (id)[[UIColor darkKinepolisColor] CGColor], nil]; layer.locations = [NSArray arrayWithObjects: [NSNumber numberWithFloat:0], [NSNumber numberWithFloat:0.4], [NSNumber numberWithFloat:0.6], [NSNumber numberWithFloat:1], nil]; layer.startPoint = CGPointMake(0, 0); layer.frame = self.layer.bounds; layer.endPoint = CGPointMake(1, 1); layer.contentsGravity = kCAGravityResize; [self.layer addSublayer:layer];

优秀的开发人员可以帮我解决这个问题吗？谢谢！

Could you, fine developers, help me with this problem? Thanks!

推荐答案

从我所见，CAGradientLayer不支持抖动，但CGGradient支持抖动。请参阅我的答案此处。另请参阅其他答案，例如关于使用CGGradient。

From what I've seen CAGradientLayer does not support dithering, but CGGradient does. See my answer here. Also see the other answers for example on using CGGradient.
