Question

I am almost finished with the iPhone version of my app when I realized that I’m going to have to (probably?) write conditionals for every UI element because they use different graphics. This will make my code very messy. I have 15 different custom UI controls and I can’t imagine that setting up a conditional (“if ipad load image_ipad, if iphone load image_iphone”) for every method is the best way to do this. Can anyone suggest a particular technique for dealing with this? Or is there a way to name images like you can between retina and regular?

Answer 1

You will need just to pass the basic image name .. lets say our image name is “Apple.png” ,, then you will write the get image name like this UIImage *image = [UIImage ImageNamed:@"Apple.png"] and the name for the image for the following cases will be :

1.iPad > put ~ipad , image name will be "Apple~ipad.png"

2.iPhone > put ~iphone , image name will be "Apple~iphone.png"

3.for retina display > put @2x , image name will be "[e-mail]"

4.if you have diffrenet image for retina diplay for ipad and iphone it will be like this ,, for iPad "Apple@2x~ipad.png" ,, for iPhone "Apple@2x~iphone.png"

If you name it like this iOS will detect the best match image name and load it.
