any help or a shove in the proper direction. Soon the image will change every time day as well so any help/thoughts on that would be of great appreciation.

推荐答案

这里的probleme是 dataWithContentsOfURL：是在主线程上，所以它会阻止你的UI时图像被下载。

The probleme here is that dataWithContentsOfURL: is on the main thread, so it will block your UI when the image is downloaded.

您必须异步下载。对于我个人使用很大的一块code的我在互联网上找到： SDWebImage 。它不正是你想要的。

You have to download it asynchronously. For that I personally use a great piece of code i found on the internet : SDWebImage. It does exactly what you want.
