You can use 

Class class = NSClassFromString(@"RootViewController");

NSClassFromString

Obtains a class by name.

Class NSClassFromString ( NSString *aClassName );

Parameters

aClassName

The name of a class.

Return Value

The class object named by aClassName, or nil if no class by that name is currently loaded. If aClassName is nil, returns nil. Availability

Available in iOS 2.0 and later.

There is a lot of methods like this in foundation framework

NSGetSizeAndAlignment
NSClassFromString
NSStringFromClass
NSSelectorFromString
NSStringFromSelector
NSStringFromProtocol
NSProtocolFromString

Refer Foundation Functions Reference
