iOS开发笔记--描边label

今天需求突然要求需要描边文字，在网上找了一下，发现挺简单的，自己封装了一个

- (void)drawTextInRect:(CGRect)rect {

    CGSize shadowOffset = self.shadowOffset;
    UIColor *textColor = self.textColor;

    CGContextRef c = UIGraphicsGetCurrentContext();
    CGContextSetLineWidth(c, self.outlineWidth);
    CGContextSetLineJoin(c, kCGLineJoinRound);

    CGContextSetTextDrawingMode(c, kCGTextStroke);
    self.textColor = self.outlineColor;
    [super drawTextInRect:rect];

    CGContextSetTextDrawingMode(c, kCGTextFill);
    self.textColor = textColor;
    self.shadowOffset = CGSizeMake(0, 0);
    [super drawTextInRect:rect];

    self.shadowOffset = shadowOffset;
}
