objective c - Switching to a UITabBarController at a specific index -


I am trying to switch back to UITabBarController in a specific index. My method does not seem to work here. My code is:

BaseViewController.m 

  - (zero) switch tab visibility: (NSString *) viewName inx: (int ) Index {UIStoryboard * storyBoard = [UIStoryboard storyboardWithName: @ "man_iphone" bundle: zero]; UITabBarController * View = [storyBoard instantiateViewControllerWithIdentifier: viewName]; View.tabBarController.selectedIndex = Index; [Self-present ViewController: see animated: yes complete: zero]; }

ChildViewController.m (BaseViewController inherits) 

  - (IBAction) Backbuttonclosed: (ID) sender {[Self switch tab visibility: @ "Tab view" Inks : 1]; }

It goes back to the UITabBarController, but the index argument does not appear because it always goes to index 0. 

  - (zero) switch tab view: (NSString *) viewName Inx: (int Index) {UIStoryboard * StoryBoard = "post-text" itemprop = "text" [UIStoryboard storyboardWithName: @ "men_iphone" bundle: zero]; UITabBarController * View = [storyBoard instantiateViewControllerWithIdentifier: viewName]; View.tabBarController.selectedIndex = Index; [Self-present ViewController: see animated: yes complete: zero]; }  
  - (zero) switch tab visibility: (NSString *) viewName Inx: (int Index) {UIStoryboard * storyBoard = [UIStoryboard storyboardWithName: @ "men_phone" bundle: zero]; UITabBarController * View = [storyBoard instantiateViewControllerWithIdentifier: viewName]; View.selectedIndex = Index; [Self-present ViewController: see animated: yes complete: zero]; }

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
