Among the myriad of problems I'm having with this application a new one
developed when I began adding a shadow to text.
The default text shadows look terrible on iPhone. This I subclassed UILabel and
did an override of drawTextInRect
Well in order to draw with the correct colors I have had to do all my custom
stuff and then call [super drawTextInRect:rect];
It all works until an Italic font is used. Then the last maybe 5 pixel are cut
out of the text. I've attempted to adjust both the bounding box of the parent
view and the subclassed label both, and it does not seem to change the views at
all. So I'm not entirely sure how but I'm screwing up adjusting a rectangle…
(Hoiw hard is it to add 6 pixels to width of a darn rect?)
Anyway. So I attempted to use a string drawing method, which would among other
things allow me to set the alignment. This works, until I click the text (which
selects it) And it also fails to draw in the correct color. (Always black
instead of whatever it should be)
Is string drawing possible if I want color? I need to override to get nice
shadows but it creates this nightmare.
CGSize myShadowOffset = self.offset;
float myColorValues[] = {0, 0, 0, self.depth};
CGContextRef myContext = UIGraphicsGetCurrentContext();
CGContextSaveGState(myContext);
CGColorSpaceRef myColorSpace = CGColorSpaceCreateDeviceRGB();
CGColorRef myColor = CGColorCreate(myColorSpace, myColorValues);
CGContextSetShadowWithColor (myContext, myShadowOffset, self.spread,
myColor);
CGSize newSize = rect.size;
CGSize imgSize = [self.text sizeWithFont:self.font];
imgSize.width +=6; //this does nothing
//everything below adjusts for the shadow which is a flipping train
wreck of its own.
CGPoint p;
CGFloat x=0.0,y=spread;
if (myShadowOffset.width <=0) {
x =((newSize.width -
(imgSize.width+(spread*2)))/2)+abs(myShadowOffset.width);
}
else if(myShadowOffset.width >0){
x =0;
}
p = CGPointMake(x, y);
rect.origin = p;
rect.size = imgSize;
[super drawTextInRect:rect];
CGColorRelease(myColor);
CGColorSpaceRelease(myColorSpace);
CGContextRestoreGState(myContext);
