I have a ViewController1 and ViewController2. ViewController1 has a NavigationController set to it. I have a button (Custom Search Icon) on the NavigationBar. Now I press control+click and drag to ViewController2 and set it to Show. When I press it, it doesn't work. I also tried to drag the button to ViewController1 and set it as an IBAction but that doesn't work either.
What I want accomplished: I want to create a button on the left side of the NavBar. When clicking it, I want to be add the searchbar and allow the user to search from an array. What is the best way about doing this? The search bar also has the cancel button, and if pressed the user should return back to his previous ViewController. I don't want anyone to the work for me but if you could point me to the right direction, it would be awesome.
I'm assuming by "Custom Search Icon", you mean a UIBarButtonItem in the navigation bar. If that's the case you should be able to segue to a controller using the technique you described, so you could try putting in a new UIBarButtonItem and try again.
But for the problem you're describing I might recommend a slightly different approach using UISearchController. Since it sounds like you're using storyboards, drag in the Search Bar and Search Display Controller from the object library to your controller, just below the navigation bar.
Check out UISearchController documentation: [https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UISearchController/ ]
And here's a sample project from Apple: [https://developer.apple.com/library/ios/samplecode/TableSearch_UISearchController/Introduction/Intro.html ]
Good luck!
