在UIButton中使用替代UILabel

Question

this is my first question on this message board so please go easy on me :)

A while ago I came across a useful piece of code to change a UILabel, this basically surounds the text in the label with a black (or an other color) outline.

- (void)drawTextInRect:(CGRect)rect; {

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

CGContextRef c = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(c, 2);
CGContextSetLineJoin(c, kCGLineJoinRound);

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

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

self.shadowOffset = shadowOffset;

}

I successfully used this as a good template to subclass my UILabels, and now I would say I have a fair understanding on subclassing.

What I would like to do is use this subclass as the UILabel part of a UIButton so that the text within my buttons have a matching black outline.

Any help or even just being pointed in the right direction would be greatly appreciated.

Thanks

Why not just subclass UIButton , and then within that subclass make the same changes you made in your UILabel subclass to the button's label property. Basically you would do everything the exact same way, except all of your changes would refer to self.titleLabel instead of just self .
