//继承UILabel以后重载drawTextInRect- (void)drawTextInRect:(CGRect)rect { CGSize shadowOffset = self.shadowOffset; UIColor *textColor = self.textColor; CGContextRef c = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(c, 1); CGContextSetLineJoin(c, kCGLineJoinRound); CGContextSetTextDrawingMode(c, kCGTextStroke); self.textColor = [UIColor whiteColor]; [super drawTextInRect:rect]; CGContextSetTextDrawingMode(c, kCGTextFill); self.textColor = textColor; self.shadowOffset = CGSizeMake(0, 0); [super drawTextInRect:rect]; self.shadowOffset = shadowOffset;} |
