I'm trying to underline label's text in UIButton. But it didn't work for me.
My code in viewDidLoad
method:
CGFloat x = 13.0f;
CGFloat y = 15.0f;
if (self.numberOfFirstButton == 0) {
self.numberOfFirstButton = 1;
}
for (NSUInteger i = 1; i <= 5; i++) {
for (NSUInteger j = 0; j < 10; j++) {
UIHouseButtons *button = [[UIHouseButtons alloc] init];
[button setFrame:CGRectMake(x+(47*j), y, 30.0f, 30.0f)];
[button setTitle:[NSString stringWithFormat:@"%i", self.numberOfFirstButton] forState:UIControlStateNormal];
[button drawRect:CGRectMake(x+(47*j), y, 30.0f, 30.0f)];
[self.view addSubview:button];
self.numberOfFirstButton++;
}
y += 48.0f;
}
my drawRect
method
- (void)drawRect:(CGRect)rect
{
CGRect textRect = self.titleLabel.frame;
// need to put the line at top of descenders (negative value)
CGFloat descender = self.titleLabel.font.descender;
CGContextRef contextRef = UIGraphicsGetCurrentContext();
// set to same colour as text
CGContextSetStrokeColorWithColor(contextRef, self.titleLabel.textColor.CGColor);
CGContextMoveToPoint(contextRef, textRect.origin.x, textRect.origin.y + textRect.size.height + descender);
CGContextAddLineToPoint(contextRef, textRect.origin.x + textRect.size.width, textRect.origin.y + textRect.size.height + descender);
CGContextClosePath(contextRef);
CGContextDrawPath(contextRef, kCGPathStroke);
[super drawRect:rect];
}
There are all my buttons in view but label's text is not underlined. What I'm doing wrong?
You may subclass from UILabel and override drawRect method:
- (void)drawRect:(CGRect)rect {
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextSetRGBStrokeColor(ctx, 207.0f/255.0f, 91.0f/255.0f, 44.0f/255.0f, 1.0f); // RGBA
CGContextSetLineWidth(ctx, 1.0f);
CGContextMoveToPoint(ctx, 0, self.bounds.size.height - 1);
CGContextAddLineToPoint(ctx, self.bounds.size.width, self.bounds.size.height - 1);
CGContextStrokePath(ctx);
[super drawRect:rect];
}
then put a custome button over that label.
