Crash on init

[DennisDreissen]

I can't get the drop down menu to work, it keeps crashing as soon as it starts loading. It crashes at the point where it creates the frame in the "init" function. I am using Xcode 6.4 with iOS 8.

Here's my code:

import UIKit
import CVCalendar
import BTNavigationDropdownMenu

class RosterViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {

@IBOutlet weak var menuButton:UIBarButtonItem!
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var calendarView: CVCalendarView!
@IBOutlet weak var menuView: CVCalendarMenuView!

var menuViewNav: BTNavigationDropdownMenu!

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.delegate = self
    tableView.dataSource = self
    tableView.tableFooterView = UIView()

    let items = ["Most Popular", "Latest", "Trending", "Nearest", "Top Picks"]
    menuViewNav = BTNavigationDropdownMenu(title: "Hey", items: items)
    menuViewNav.didSelectItemAtIndexHandler = {(indexPath: Int) -> () in
        print("Did select item at index: \(indexPath)")
    }
    self.navigationItem.titleView = menuViewNav

    if self.revealViewController() != nil {
        menuButton.target = self.revealViewController()
        menuButton.action = "revealToggle:"
        self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
    }
}

I fixed it by setting the navigationController manually. I'm now sending the navigationController together with the title and the items.

BTNavigationDropdownMenu(title: "Hey", items: items, nav: navigationController!)

Not sure if this is the proper way to do it, but at least it works.

Same issue, crashing on // Set frame
let frame = CGRectMake(0, 0, titleSize.width + (self.configuration.arrowPadding + self.configuration.arrowImage.size.width)*2, (self.navigationController?.navigationBar.frame.height)!)

show thread 1 exc_bad_instruction (code=exc_i386_invop subcode=0x0)

The navigationController is nil.

Hi, please check this commit. I fixed bug relating to the availability of navigation controller. I also updated to CocoaPods for this fix (version 0.1.8).

I'm getting same exact issue, The navigationController is nil. Using CocoaPods version 0.1.8.

The same error

The top viewcontroller in my app is a UITabBarController instead of UINavigationController, so I think it should be able to set by programmer.
