I can't seem to be able to get the keyboard to default to black in my code. I've tried the solutions in the other posts with no success. Not sure if I am missing something. I want it to apply to all view controllers so I want to put it in my app delegate. This is the code I believe should be doing the trick, but its not working for me.
textfield.keyboardAppearance = UIKeyboardAppearanceDark;
I don't know what your variable "textfield" is, but if it is an instance of a UITextField, then it will only set the keyboard appearance for that specific textField instance.
If on the other hand you want to set it for all UITextFields throughout your app use instead:
[[UITextField appearance] setKeyboardAppearance:UIKeyboardAppearanceDark];
somewhere after your appstart, e.g. application: didFinishLaunchingWithOptions: in your app delegate.

I have a view controller in one storyboard that I'd like to reuse in another storyboard's Tab Bar Controller. In XCode, I can add a storyboard reference and then ctrl-drag from the Tab Bar Controller to it, and it shows up as another tab, just like a View Controller would in the same storyboard. I'm trying to do this in VS 2017 though and it doesn't seem to work. Or if it does, I'm unsure of how to do it. I tried adding a storyboard reference and ctrl-dragging, just like I do for normal View Controllers. I select "Tab" under "View Relationship" which pops up when I finish dragging, but it never makes the link and never makes the tab.
Is this even something that is valid? And if it is, is it a bug/limitation with VS that I can't do this, and is there a workaround?
Edit:
I managed to get this to work programmatically. Here's what I did in case anyone wants to know. However, I still would like to know the answer to my previous questions.
First, in your desired VC (I'm going to call it TestVC), make sure you add a Tab Bar Item (not a tab bar). Set up the title and image as you would normally. Then, in your Tab Bar Controller's ViewDidLoad method, do something like this:
var storyboard = UIStoryboard.FromName("StoryboardNameTestVCIsIn", null);
var vc = storyboard.InstantiateViewController("TestVC");
var existing = new List<UIViewController>(ViewControllers);
existing.Add(vc);
ViewControllers = existing.ToArray();

It is not support to add Tab relationship by this way. As you mentioned above, you could only implement that programmatically. Maybe in the near future Xamarin will support it like in Xcode.
Click on the segue , and you can see all the actions you can do.
I saw this article on the code project, where the author mentions the possibility of making an ApplicationBar persistent.
I want my app bar always visible!
You can make the app bars display at all times by setting the IsPersistent property to True.
I'd like to do the same in my Windows 8.1 (WinRT) project. I can't see a IsPersistent property for the CommandBar class here.
It's not IsPersistant, it's IsSticky
Using the CommandBar within the Page.Bottom[Top]AppBar areas will not give you this ability. As presently defined, AppBars are transient and can always be dismissed by the user. IsOpen/IsSticky are ways to help it stay open longer, but the user can always still dismiss them.
If you want a persistent 'appbar' feel that isn't dismissable, you'll want to just create something that stays bottom-aligned on your view. You will however, be having different behavior than the user may expect given other apps.
You can always use Closed Method of the CommandBar.
And set within the method IsOpen to True.
This way to force the CommandBar to always be visible even if the user press Windows+Z, Right click, etc.
Getting started with xCode 4.6.3 and I'm running into a hiccup.
I've built a simple app using the UIWebView to display a local HTML file and it's contents. I used that to debug any issues with the HTML and/or image displays and I'm all set.
Now I need to recreate that within a larger project I've built with storyboards for all my navigations between multiple view controllers. My issue comes when I'm trying to control-click drag from the WebView into the ViewController.h code below the #interface like many tutorials show, and that worked fine within my smaller single view controller app. It won't do it. I know I'm missing something obvious here. Am I going to have the set up these screens (I have multiple ones to do this same way) as separate xib files and add them into my main project?
Thanks for any help and clarification.

You can create a class called for example myWebViewController and in Interface builder add a UIWebView to it. The control+drag to the header file will work.
Every time you want a UIViewController that has a browser in it, define its class as myWebViewController in Interface Builder.
Try not to repeat code. If you see UIViewControllers or any other UIView...that do the same thing, you can group them into a class that you use over and over.
I'm developing an App with some maps functionalities (among other things), I'd like to draw a map from my current location to a given destination, but I do not want to use the shareadapplication, The shared application does not have a BACK button for example and some other navigation items I already have.
I want to do it in my own viewcontroller with mkmapview on it.
I already have the code to place the pin annotations, what I need is to trace the driving directions from A to B.
The other option is to use the [[UIApplication sharedApplication] openURL:url] call to appear inside the viewcontroller window so I can keep my navigation items.
Any ideas?

You can't do the "other option". iOS apps do not run inside windows that you can put within your app, they are full screen apps and you can make you app switch to them, but you can't make other apps switch back to yours.
So, the big question is, where are you going to get driving directions from? Check out GoogleMapsSDK, OpenStreetMap and CloudMade, because iOS maps won't give you the directions.
I've currently got two view controllers A and B, A uses a segue to push B and this works back and forth nicely, however based on some button presses in view controller B i want to change the text within a UITextView in controller A.
I've had a look at previous posts but i'm a novice at present and was confused by the way in which i should go about doing this.
I'd love to be able to get my head around how interactions are best done between various parts of the app. Also i was wondering if there is a way i can tap into a segue returning to trigger some other code.
Thanks
Edit:
OK perhaps i was a little bit limited with my information, from what i can gather reading other posts they are manually creating a variable for the viewcontroller (A) in viewcontroller (B) then accessing it in the second view controller (B) and setting a variable (property and synthesize) to edit that way, however i have the viewcontrollers embedded in a navigation controller and using a push setup in the storyboard (GUI system). I'm not sure if i have to create a variable to do this or if because they exist in the storyboard there is another way, if someone could just point me in the direction of a post that helps to explain this (i am looking at the moment too) i'd be very grateful.
OK well here's how i got it to work but i imagine there are:
A: Better ways to do it.
B: Changes depending on your setup.
I had my two view controllers embedded in a navigation controller, and used a segue push to access the second view controller each had a different class (all setup in the storyboard thing).
To get it working for me i did the following:
I have a singleton (a class that stores all my data but is global to the app so the variables can be accessed from anywhere in the app) this allows me to have variables that i can access from any view controller. A great tutorial on this can be found here
I then created an NSString variable (passedNote) and updated the value of this variable from the ViewController B, when my button was pressed.
Next when viewController A is loaded (in the viewWillAppear: (BOOL)animated method) i append or replace the value of the textview (dependent on some logic) I have with the global variable (passedNote).
Hope this helps anyone who had the problem.
