如何在Xcode 4.2下用不同的图形集开发iOS应用？

Question

I have this app with one whole set of images, but I would like to add for example personalized set of graphics. Is there an easy way to organize and develop source code and not to get lost while switching between these sets of images?

One way I see it is to have on my hard drive two folders with graphics and before releasing replace in project current images with personalized set... is there a better way?

I'm using Xcode 4.2 and iOS 5.0 for this app.

Probably the easiest and most reliable in terms of maintainance is to write your own image access function or marco, that is controlled in one place globally. Then use this in all cases where you want to have the flexibility for differnt images for example like this. I just got used to this way of assigning an image with stretchableImageWithLeftCapWidth because it adjusts the size nicely.

Of course you may use any other way to assign your images, like directly without use of stretchableImageWithLeftCapWidth

Anyway, this is my suggestion:

   NSString *s = [NSString stringWithFormat:@"%s%i",@"imageName",CONST_VERSION];
   UIImage *theImage = [UIImage imageNamed:s];
   myImageView.image = [theImage stretchableImageWithLeftCapWidth:12 topCapHeight:0];

and you can do

 #define CONST_VERSION 1 // or 2

Then name your images like:

myImage1.png 

and

myImage2.png
