iphone-sdk-4.1

I followed the tutorial: http://useyourloaf.com/blog/2010/5/18/adding-a-settings-bundle-to-an-iphone-app.html And the Toggle Switch (that I just created based on the tutorial) was not in the Settings App. Every time I did an NSLog on the state of the switch, it would return "(null)".

Should I do it programmatically, or in a XIB? Edit: I'm looking to do this with custom icons/selected icons and having icons only.

Tirth Here is a good way to crop an image to a CGRect: - (UIImage*)imageByCropping:(UIImage *)imageToCrop toRect:(CGRect)rect { //create a context to do our clipping in UIGraphicsBeginImageContext(rect.size); CGContextRef currentContext = UIGraphicsGetCurrentContext(); //create a rect with the size we want to crop the image to //the X and Y here are zero so we start at the beginning of our //newly
