如何激活@ 2x高分辨率图形以进行视网膜显示? [英] How to activate @2x high res graphics for retina display?

问题描述

我有一个旧应用，并为其创建了@ 2x高分辨率图像.现在，我将所有这些内容都整合到了我的项目中，但是当我在视网膜显示测试设备上构建并运行该应用程序时，看不到高分辨率图像.

I have an old app and created @2x high res images for it. Now I've incorporated all these into my project, but when I build and run the app on the retina display test device I do not see the high res images.

可以肯定的是，我用奇怪的颜色制成了其中的一些，所以我确切地知道是否使用了@ 2x.我还尝试先清理我的构建和所有目标.似乎该设备拒绝使用高分辨率图像.

To be sure, I made some of them with strange colors so I know exactly if @2x is used or not. I also tried to clean my build and all targets first. It just seems the device is refusing to use high res images.

我必须在info.plist中设置一个标志吗?

Must I set a flag in the info.plist?

推荐答案

这是imageWithContentsOfFile:的已知问题.在API文档中，它说它应该可以工作，但实际上却不起作用(在4.0.x中不起作用，不确定较新的版本).他们有一天会修复它.

it's a known issue with imageWithContentsOfFile:. In API docs, it says it should work, in reality it doesn't (didn't work in 4.0.x, not sure about newer). They'll fix it one day.
