如何从Xcode 8中的Assets.xcassets添加不同屏幕尺寸的图像？

问题描述

我为登录屏幕创建了不同大小的背景图像。
我参考苹果链接

另一个问题是当我创建图像集时，应该将哪个图像大小拖到哪个位置。我不知道那个。或者我们只需要3张图片（通用行）？

那么，景观图像怎么样？我应该把它放在哪里？

解决方案

我会创建以下尺寸：

iPhone：

• @ 1x - 640 x 1136（iPhone SE）


• @ 2x - 750 x 1334（iPhone 7,6S）


• @ 3x - 1242 x 2208（iPhone 7 Plus， iPhone 6S Plus）
  

iPad：

• @ 2x - 2048 x 1536（iPad Air，Retina iPad 1st& 2nd Generation / 3rd& 4th& Pad Mini 2nd& 3rd Generation）

I create different sizes of background image for my Login screen.
I refer to the apple link https://developer.apple.com/ios/human-interface-guidelines/graphics/launch-screen/
But I'm not doing Launch Screen and I just want to add background to Login screen.

I would like to know which is 1x , 2x and 3x ?

Another problem is when I create Image Set, which size of image should be drag to which place. I have no idea of about that. Or do we need only 3 images (in universal row)?
And then , how about for Landscape image? Where should I put this?

解决方案

I would have created the following sizes:

iPhone:

• @1x - 640 x 1136 (iPhone SE)
• @2x - 750 x 1334 (iPhone 7, 6S)
• @3x - 1242 x 2208 (iPhone 7 Plus, iPhone 6S Plus)
  

iPad:

• @2x - 2048 x 1536 (iPad Air, Retina iPad 1st & 2nd Generation / 3rd & 4th & Pad Mini 2nd & 3rd Generation)
