If I have a UIViewController subclass, how can I get the class name as string? I've tried doing [vc class], but this returns a Class object, not an NSString.

If ending up here from google and actually want the SWIFT 3 answer, use eg:
String(describing: MyViewController.self) : stackoverflow.com/a/34878224/1736679You can do something like this
NSString *strClass = NSStringFromClass([viewController class]);

Use the function:
const char * class_getName(Class cls) as
class_getName ([vc class]);

how do I cast from char* to NSString?
Duncan C
you don't cast from char* to NSString. You have to create a string from bytes using a call like initWithBytes:length:encoding:. You'd probably use use the encoding NSASCIIStringEncoding. See the other poster's message about NSStringFromClass. That's much easier to use than the Objective C runtime function class_getName().

class_getName() is the runtime function that NSStringFromClass would use under the hood.you can do some thing like the following when you instantiate your object:
[[NSClassFromString(@"className1") alloc] init];

xonegirlz asked how to get an NSString from a class, and your answer gets an instance of a class from an NSString (i.e. you gave the reverse of the answer).
