Iphone – popover segue with no anchor, MKMapView

iphoneuipopovercontrolleruistoryboard

I'm trying to present a popover over a pin I added to a MKMapView. I added a UIViewController to my storyboard, and dragged a segue from the MKMapView in one view controller to the viewController I want to show in my popover and selected popover. I get the error:

Popover segue with no anchor

In IB, I see "Drag to select an anchor", but when I try dragging it anywhere within the first viewController that has the MKMapView in it, nothing gets selected. I'm not sure where to go from here and if popover's from a view that is created dynamically can be used to present a popover with Storyboards. I know I can do it in code, but then I have to copy and paste my setters in prepareForSegue:. Thoughts? Thanks.

You need to make a custom annotation view. This will look like a popover view but it is actually different. A great tutorial on this can be found here: http://www.raywenderlich.com/30001/overlay-images-and-overlay-views-with-mapkit-tutorial

Essentially, you need to go NEW->NEW FILE-> the first option on the top left for OBJECTIVE C CLASS-> Name it whatever you want, I recommend CustomAnnotationView, and make it part of NSObject (rather than the default UIViewController)->follow the instructions on the above listed tutorial. If that tutorial does not work for you then you can search "custom map annotation" and many others will pop up. Apple even has a couple good (though outdated) sample projects which due this, such as a weather app and a callouts app with callouts for three locations in San Francisco.

Ios – creating button for popover view anchor at run time

I had the same problem and solved it by creating a UIBarButtonItem in the Storyboard for the view controller but not part of the view hierarchy.

In IB, Drag a bar button item to the dark bar below the view controller view, drop it next to the "First Responder" and "View Controller" icons. Create a (strong) IBOutlet for it. Then create a popover segue from it to the destination view controller by dragging from the bar button item to the destination. It seems like this is the only way to set it as the anchor. Choosing it as the anchor for an existing segue does not work (looks like an IB bug).

enter image description here

In viewDidLoad you can assign this bar button item to the navigationItem (or where ever you like) and the segue works as expected.

You can call a segue yourself using

[self performSegueWithIdentifier: @"SegueToScene1" sender: self];
