Question

Answer 1

Use this It may Help's you

 NSString *CurrentSelectedCViewController = NSStringFromClass([[((UINavigationController *)viewController1) visibleViewController] class]);

Answer 2

The most common technique is to use -isKindOfClass:

if ([[viewContrells lastObject] isKindOfClass:MyViewController.class]]) {
    // ...
}

Using NSStringFromClass to compare strings is not a very nice solution because your code will break if you refactor the view controller to rename it.

Answer 3

if ([NSStringFromClass([[viewContrlls lastObject] class]) isEqualToString: @"Whatever"]){
}

You could also use -isKindOfClass if you prefer to compare directly an instance to a specific class.

Answer 4

Swift version:

static func getClassNameAsString(className: AnyObject) -> String {
    return _stdlib_getDemangledTypeName(className).componentsSeparatedByString(".").last!
}
