iPad2与iPad3手动定位的项目有变化吗？

Question

since the iPad 3("The New iPad") has twice the pixels I obliviously have my make any images twice as big. But my question is since it has twice the pixels if I am manually placing an object on screen, with say CGRectMake, will it appear in different places on the iPad2 from the iPad3?
say I'm using the code below to position a button on screen:

 CGRectMake(375,500,125,125); 

since its positioned at 375 pixels on the X coordinate wouldn't it appear in different places on the iPad 2 vs the iPad3 since the iPad3 has twice as many pixels?

I'm sure this is a dumb question that any mildly experienced iOS developer would laugh at but since a simple Google search didn't turn anything up I figured id ask.

Thanks!

Answer 1

Though the amount of pixels may differ among devices, Core Graphic's coordinate system does not. This is because CG expresses itself in points, not pixels.
