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开发者_C百科, kCGTextFillStroke);
CGContextSaveGState(context);

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

CGContextRestoreGState(context);

UIFont *font =  [UIFont fontWithName:@"Arial" size:14];
CGPoint point = CGPointMake(0,0);

CGContextRef context = UIGraphicsGetCurrentContext();

CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 0.7);
CGContextSetRGBStrokeColor(context, 0.0, 0.0, 0.0, 1.0);
CGContextSetTextDrawingMode(context, kCGTextFillStroke);
CGContextSaveGState(context);
[@"Label" drawAtPoint:point withFont:font];

CGContextRestoreGState(context);

you can look here:

and in the example code here: http://developer.apple.com/library/ios/#samplecode/QuartzDemo/Introduction/Intro.html%23//apple_ref/doc/uid/DTS40007531

I have a clean solution implementing UILabelStroke subclass:

@implementation UILabelStroked
@synthesize strokeColor;
- (void)drawTextInRect:(CGRect)rect {

    UIColor *borderColor = self.strokeColor;
    UIColor *fillColor = self.textColor;
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGContextSetLineWidth(context, 1.0f);
    CGContextSetTextDrawingMode(context, kCGTextStroke);
    self.textColor = borderColor;
    [super drawTextInRect:rect];

    CGContextSetLineWidth(context, 0.0f);
    CGContextSetTextDrawingMode(context, kCGTextFillStroke);
    self.textColor = fillColor;
    [super drawTextInRect:rect];
}
