In iOS7, we use attributes to draw text:
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:largeFont,NSFontAttributeName, [UIColor whiteColor],NSForegroundColorAttributeName,[UIColor blackColor], NSStrokeColorAttributeName,nil];
[myString drawAtPoint:myPosition withAttributes:dictionary];
But the stroke is not on outside of the text,it's center. Anyone know how to add outside stroke in iOS7?
