Create text Stroke for UILabel iphone

I was wondering how can I create text stroke for UILabel in iOS4 ? I need some suggestion . I want something like this :

EDITED :

UIFont *font =  [UIFont fontWithName:@"Arial" size:222];
CGPoint point = CGPointMake(0,0);

CGContextRef context = UIGraphicsGetCurrentContext();

CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 0.7);
CGContextSetRGBStrokeColor(context, 2, 2, 2, 1.0);
CGContextSetTextDrawingMode(context, kCGTextFillStroke);
CGContextSaveGState(context);

// I change it to my outlet
[label.text drawAtPoint:point withFont:font];

CGContextRestoreGState(context);
