CALayer is not clear when drawing
I use CALayer to make a tab bar. But sometimes, drawing is not clear as you can see 'index.pgiu'. If I see this on retina display, it is more worse than usual screen. (See difference between 'index.pgiu' and 'Flow' label )
How can I fix it? Even I cannot find keyword for google.
