Question

I’ve been trying to display text using a Quartz context, but no matter what I’ve tried I simply haven’t had luck getting the text to display (I’m able to display all sorts of other Quartz objects though). Anybody knows what I might be doing wrong?

example:

-(void)drawRect:(CGRect)rect {      // Drawing code   CGContextRef  context = UIGraphicsGetCurrentContext();   CGContextSelectFont(context, 'Arial', 24, kCGEncodingFontSpecific);   CGContextSetTextPosition(context,80,80);   CGContextShowText(context, 'hello', 6);   //not even this works   CGContextShowTextAtPoint(context, 1,1, 'hello', 6); }

Here is a fragment of code that I’m using.

UIColor *mainTextColor = [UIColor whiteColor]; [mainTextColor set]; drawTextLjust(@'Sample Text', 8, 50, 185, 18, 16); 

And:

static void drawTextLjust(NSString* text, CGFloat y, CGFloat left, CGFloat right,                           int maxFontSize, int minFontSize) {     CGPoint point = CGPointMake(left, y);     UIFont *font = [UIFont systemFontOfSize:maxFontSize];     [text drawAtPoint:point forWidth:right - left withFont:font        minFontSize:minFontSize actualFontSize:NULL        lineBreakMode:UILineBreakModeTailTruncation        baselineAdjustment:UIBaselineAdjustmentAlignBaselines]; }
