在OSX 10.9之前的canDrawSubviewsIntoLayer的替代方法 [英] Alternative method for canDrawSubviewsIntoLayer prior to OSX 10.9

问题描述

我需要在我的图片视图中实现下面的代码，使gif正常动画：

I needed to implement the following code in my image view to make a gif properly animate:

self.homeView.radarImageView.animates = YES;
self.homeView.radarImageView.canDrawSubviewsIntoLayer = YES;
self.homeView.radarImageView.image = currentData.radarImage;

$ b <与OSX之前10.9。有没有另一种方法，我可以使用它将使这项工作在OSX 10.7和更高？

Unfortunately, the canDrawSubviewsIntoLayer method is not compatible with OSX prior to 10.9. Is there an alternative approach that I can use that will make this work in OSX 10.7 and higher?

推荐答案

避免基于图层的视图在10.8及以下，因为它们似乎与动画的gif混合不好

avoid layer-based views under 10.8 and below as they don't seem to mix well with animated gifs

效果而不使用图层）
对于渐变，例如有NSGradient，需要NSColors并且可以填充一个

as asked in the comment, one can draw gradients (and all other effects without using layers)
For Gradients for example there is NSGradient that takes NSColors and can fill a rect

一个NSView可以绘制所有你想要的背景：颜色，渐变，模式图像，只是一个图像，边框，圆角...所有在一个视图

A NSView that can draw all that you ever want in your background: color, gradient, patttern image, just an image, a border, rounded corners... all in one view https://github.com/Daij-Djan/DDBackgroundView
