iPhone和iPad的iOS图像大小

Question

I am developing universal app for iOS,

I am using Autolayout feature in my app,

I have one doubt:

I want to apply background image in my app, How many background image i will have to make ?? and what will be the naming conventions of the images ? so that iPhone automatically takes corresponding images according to device.

Like we gives on launch images, default@2x.png , Default-568h@2x.png , Default-Portrait@2x.png and device automatically understands it's corresponding images.

Answer 1

you need 2 types of images for iphone and ipad .

For ipad you just need to add ~ipad before .png .
eg image.png for iphone and image~ipad.png for ipad .

Do the same for Retina display images also.

eg

iPhone Retina : image@2x.png

iPad Retina : image@2x~ipad.png
