Objective-C classes may have multiple
initmethods. Usually, one of them is called the “Designated Initializer”, and is the one all the rest call.If you are subclassing, and creating an
initmethod with a different signature, you should call the superclass’ designated initializer (although calling any initializer of the superclass will work as well). The documentation for the classes will usually tell you what the designated initializer is.For instance, in
UITableViewCellthe designated initializer isinitWithStyle:reuseIdentifier:and is the one you should call if you subclass and create aninitmethod with a different signature.
