CGContext - PDF margin

I am showing PDF content on a view using this code using Quartz Sample: // PDF page drawing expects a Lower-Left coordinate system, so we flip the coordinate system // before we start drawing. CGContextTranslateCTM(context, 0.0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); // Grab the first PDF page CGPDFPageR...

Why keep using CCSprite drawing will have a line in the middle?

The image that should be display: But actually, it shows like this: It seems some over lapping, what's happen? thank you. ...
