iPad应用程序中所有标签的模糊字体

Question

We have been developing an iPad app and we are seeing one strange issue.

Once we deploy app on device , in some of the iPads we see that fonts of all the labels are coming as blurred (fonts are visible but are faded/blurred).

In some iPads, we can see the issue but couldn't see the issue on all the iPads. It is not os specific (seen on both ios5 and ios6) . Issue doesn't go even after killing app or reinstalling it.

If device show issue , it will always be there and if device doesn't show issue, it won't show it ever.

Any input on when this can happen or anyone has seen it before ?

Answer 1

Maybe the problem can be that the coordinates are not integers. You can Fix it with CGRectIntegral() . Sample:

subView.frame = CGRectIntegral(CGRectMake( 0, 0, sizeWidth, sizeHeight));

Answer 2

It depends on iPad version. Seems you can see blurry labels only on iPad 2 ( non retina display ). And it not depends on iOS version. Rounding frame and center will fix it
