iOS How to init object using string name of the class?

[Sergio10]

Hi,
Here is a code:

		NSString* className = @"SomeClass"

		UIViewController *viewController = [[(Class)className alloc] initWithNibName:aXIBName bundle:[NSBundle mainBundle]];

It crashes. How to solve the problem?

Thank you.

Use NSClassFromString to turn your string into a Class then you can alloc init as usual:

NSString* className = @"SomeClass" 

id myInstance = [[NSClassFromString(className) alloc] init];
