Declaration
Parameters
classNameThe name of a class.
Return Value
The Class object for class. Returns nil if class is not one of the classes associated with the receiver or if there is an error loading the executable code containing the class implementation.
Discussion
If the bundle’s executable code is not yet loaded, this method dynamically loads it into memory. Classes (and categories) are loaded from just one file within the bundle directory; this code file has the same name as the directory, but without the extension (“.bundle”, “.app”, “.framework”). As a side effect of code loading, the receiver posts did after all classes and categories have been loaded; see Notifications for details.
