iOS 7 force landscape on a UIViewController with UINavigationController - xcode

In my app I want one view controller to be shown in landscape because it is a signature pad. The rest of the views are portrait. I can force the view to be landscape without a problem as long as it is not embedded in a Navigation Controller. The problem is that I want the Navigation bar to show also. Does anyone know a workaround for this?

You can either present your view controller instead of push using UINavigationController (See kjam's solution in the following link) or you may try this solution of arpan_techisavy.

Linking actions to buttons on a modal/popover segue (swift 2 Xcode 7)

I'm sure I'm asking a simple question but I've only just started coding... so take pity on me!
I'm trying to figure out how to connect buttons (actions) to the viewController.swift from a modal/popover segue (I think the solution is the class but whenever I change it I get an error).
Eg.
In the storyboard, on the viewController interface, I have a button for sharing files. When I click it, a popover segue appears with two buttons on it, one for Fb one for Twitter, but I can't connect any actions from them to the viewController.swift
In another project I made a Google+ login and connected it to a modal segue but I couldn't make that work either.
Is segue the wrong thing to use?
Thanks for your help!

Your question would be easier to answer if you'd provide the actual error you're getting when you try to change the class.
It sounds like you're trying to connect the popover's buttons to actions in the presenting view controller (that is, the view controller that presented the popover), rather than the view controller of the popover itself. If that's the case, then that's the problem. You can only connect your buttons directly to actions available in the current scene.
This means you need a custom class for the presenting view controller (the one with the button that segues to the popover controller) and one for your popover. Set each scene view controller's classes to the appropriate custom classes you created (which must be a subclass of NSViewController or one of its subclasses or you won't be able to set the class name in IB) and you should be able to drag connections.

How to incorporate a UISearchController into new (iOS8) UISplitviewController

I try to build a simple app based on the UISplitViewController template from Xcode 6 for universal apps (with Storyboard and CoreData/NSFetchedResultsController). This app should also provide a search bar for the MasterViewController. Unfortunately, Xcode 6 provides no InterfaceBuilder element for the UISearchBar/UISearchController combo (only the depreciated UISearchBar/UISearchDisplayController).
In the iOS Developer library, Apple provides the "Table Search with UISearchController" example, but this is not based on the UISplitViewController and supports only iPhone.
My problem is, that I'm not able to show the detail view on the correct ViewController under all circumstances. I tried to transfer the approach from the Apple example project to the UISplitViewController template. In this, one is encouraged to show the search results in a separate UITableViewController subclass (ResultsTableViewController) and use this as the searchResultsController of the UISearchController. I was not able to create a scene in InterfaceBuilder for this setup so I had to add these manually in code.
The problems begin when I click on a table cell of the ResultsTableViewController. This vc is not part of the scene in InterfaceBuilde and I don't know how to add it to the SplitViewController setting correctly. The biggest problem is the weird behavoir of the iPhone 6 Plus and the UISplitViewController. In portrait mode it behaves like an iPhone and doesn't seem to have a SplitViewController and only uses a NavigationController to which I push my DetailViewController. In landscape mode it behaves like an iPad with SplitViewController were I have to get the second ViewController of the SplitViewController childControllers and push the DetailViewController on this one.
Now it happens, when I start in portrait mode and switch to landscape mode that the DetailViewController is all gone, showing gray space where the DetailVC should be. It seems, when going to portrait mode, the DetailViewController gets kicked from the SplitViewController (or the SplitViewController gets kicked at all in favor for the iPhones NavigationController setup). When switching back to landscape the SplitViewController is initialized again but without proper initialization of the DetailViewController.
Is there any template or suggestion on how to correctly implement search capabilities on a universal UISplitViewController?

Switching views in storyboard after executing code in xcode

I made a log-in screen that once you press the button to log-in and it authenticates the user name and password. What I want to do it switch to a different view after the authentication is completed. I am using a storyboard for this application and I have set it up so that the log-in button does a modal seque but it doesn't switch the view. I tested this with a sample button and all it does it switch the view back to the same view and refreshes the view. What do I need to add in order for my function to switch from my ViewController View (the main view) to the next view (RootViewController).
I have a navigationController and an object created from the ViewController class but I don't know how to use them in order to switch views.
Can anyone point me in the right direction? I can provide more information or sample code if needed.
If I'm following your question correctly, what you're looking for is performSegueWithIdentifier:sender:.
In general the apple documentation on view controllers in storyboards is pretty good and covers all of the relavent bits for transitioning between views in storyboards.

Handle different view controllers to achieve different views at orientation change

I have a universal app that i need to present different screen for ipad depending if the device is portrait or landscape. I am using storyboards and view controllers. In the ipad storyboard I have one view controller for Portrait and one for landscape both pointing to the same .m class and each has an identifier name.
At the didRotate method in each .m file i tried to load the correct view cotroller based on its identifier name and i used push in the navigation controller. But in this way the back button doesnt lead back to the correct orientation of the previous view.

show rootview controller (uitableviewcontroller subclass) in splitview in portrait mode

I want to show rootview controller(uitableviewcontroller sublass) in splitview in portrait mode which is by default hidden.when i switch to landscape mode its visible but i want to show this in portrait mode also.
thanx for any help.
This is not possible using the standard UISplitViewController class. Apple has a private API they use to do this same thing in the Settings app. Take a look at this MGSplitViewController which should allow you to achieve the same effect without breaking the private API rules.
Take a look at APSplitViewController.
