Question

I am testing my app in the iphone simulator To test the retina display, I’ve set the hardware to iphone(retina)
Unfortunately, the entire scene seems to be scaled to four times its normal size!
The only thing I see, is the left bottom quarter of the entire scene.
The app, since it exceeds the bounds of the screen, shows up only as a quarter on the iphone screen.
I am using Cocos2d. What is the cause of this? I also have retina display enabled in the app delegate. Any help is greatly appreciated!

Answer 1

The simulator is increasing to four times it’s normal size (twice on each axis) because by default it uses a 1:1 mapping of pixels.

In other words, one screen pixel = one device pixel. So when you go to Retina display, which doubles the retina density, you need four times as much space to display the device screen.

Edit:

In response to the updated question, you can use the ‘scale’ feature. Window->scale->50% (or command+3).
