What size has a background image to have?
提问by Zé Moreira
I'm developing a game in Swift (but not sprite kit), and i'm having a lot of trouble to make a background image that look great in every device. I recently understand the concept of the @1x, @2x and @3x images and it's pixels, but i can't find any place that say what size (width and height) an background image must have to look good both in canvas mode, preview mode and in action.
我正在 Swift 中开发一个游戏（但不是精灵套件），我在制作一个在每个设备上看起来都很棒的背景图像时遇到了很多麻烦。我最近了解了 @1x、@2x 和 @3x 图像的概念，它是像素，但我找不到任何说明背景图像必须在画布模式下看起来都很好的地方，预览模式和行动。
Anyone can help me?

设备的大小图标：
UIImageView *imageView = [UIImageView alloc]init];
imageView.frame = CGRectMake(0,0,widthInt,heightInt);
imageView.image = [UIImage ImageWithName:@"nameImage.png"];
