I'm creating a custom view, with a uiimageview as a subview. I'm then using that custom view in my navigation bar as the rightBarButtonItem. This works to display the proper icon in the proper location, but for whatever reason the function I define in "action" is never being called, so the segue isn't performed when I tap on the rightBarButtonItem. Oddly enough if I do NOT insert a custom view, but instead comment that bit out and just set a title, target, and action for rightItem then the function is performed properly. somehow adding that custom view messes with the target and action properties, but I can't seem to figure out how to fix it. Any help would be greatly appreciated!
//create custom view for right item and set it
var imageViewRight:UIImageView = UIImageView()
imageViewRight.frame = CGRectMake(5, 10, 35, 25)
let rightImage:UIImage = UIImage(named: "cameraIconInactive")!
imageViewRight.image = rightImage
var rightView:UIView = UIView()
rightView.frame = CGRectMake(0, 0, 45, 45)
rightView.addSubview(imageViewRight)
var rightItem:UIBarButtonItem = UIBarButtonItem()
//this line right below is the problem - if I comment it out and replace with a simple rightItem.title = "test" and leave everything else the same, then the method runs properly
rightItem.customView = rightView
rightItem.target = self
rightItem.action = "pushProfileToCamera"
self.navigationItem.rightBarButtonItem = rightItem
}
func pushProfileToCamera(){
println("pushing profile to camera")
self.performSegueWithIdentifier("pushProfileToCamera", sender: nil)
}
EDIT:
actually sat on this for 24 hours and came up with this solution before I saw these answer suggestions.. any reason I shouldn't do this? It works..
//create the custom rightBarButtonItem
//create the imageView with icon
var imageViewRight:UIImageView = UIImageView()
imageViewRight.frame = CGRectMake(5, 10, 35, 25)
var rightImage:UIImage = UIImage(named: "cameraIconInactive")!
imageViewRight.image = rightImage
//put the imageView inside a uiview
var rightView:UIView = UIView()
rightView.frame = CGRectMake(0, 0, 45, 45)
rightView.addSubview(imageViewRight)
//create the tap gesture recognizer for that uiview
var rightGestureRecognizer:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "pushProfileToCamera")
rightView.addGestureRecognizer(rightGestureRecognizer)
//create the uibarbuttonitem, assign our custom view to it, and insert it in the nav bar!
var rightItem:UIBarButtonItem = UIBarButtonItem()
rightItem.customView = rightView
self.navigationItem.rightBarButtonItem = rightItem
You can try to instead of linking the rightItemAction and adding a UIView to the customView, add a UIButton to the rightBarButtonItem:
var button: UIButton = UIButton()
button.setImage(UIImage(named: "cameraIconInactive"), forState: .Normal)
button.frame = CGRectMake(0, 0, 45, 45)
button.targetForAction("pushProfileToCamera", withSender: nil)
var rightItem:UIBarButtonItem = UIBarButtonItem()
rightItem.customView = button
self.navigationItem.rightBarButtonItem = rightItem
Try like this
var rightItem:UIBarButtonItem = UIBarButtonItem(image: rightImage, landscapeImagePhone: rightImage, style: UIBarButtonItemStyle.Plain, target: self, action: "pushProfileToCamera")
self.navigationController?.navigationBarHidden = false
let navigationBar = UINavigationBar(frame: CGRectMake(0, 0, self.view.frame.size.width, 64)) // Offset by 20 pixels vertically to take the status bar into account
navigationBar.backgroundColor = UIColor.blueColor()
navigationBar.delegate = self;
// Create a navigation item with a title
let navigationItem = UINavigationItem()
//menu button
let menubutton: UIButton = UIButton(frame: CGRectMake(0, 0, 30, 30))
menubutton.setImage(UIImage(named: "menu"), forState: UIControlState.Normal)
menubutton.addTarget(self, action: "btn_clicked", forControlEvents: UIControlEvents.TouchUpInside)
//menu button custom view
let leftView = UIView(frame: CGRectMake(0,0,30,30))
leftView.addSubview(menubutton)
//left uibarbutton
let leftItem:UIBarButtonItem = UIBarButtonItem(customView: leftView)
navigationItem.leftBarButtonItem = leftItem
//searchButton
let searchbutton: UIButton = UIButton()
searchbutton.setImage(UIImage(named: "search1x"), forState: UIControlState.Normal)
searchbutton.frame = CGRectMake(0, 0, 30, 30)
searchbutton.addTarget(self, action: "btn_clicked", forControlEvents: UIControlEvents.TouchUpInside)
//menu button custom view
let rightView = UIView(frame: CGRectMake(0,0,30,30))
rightView.addSubview(searchbutton)
//right uibarbutton
let rightItem:UIBarButtonItem = UIBarButtonItem(customView: rightView)
navigationItem.rightBarButtonItem = rightItem
// Assign the navigation item to the navigation bar
navigationBar.items = [navigationItem]
// Make the navigation bar a subview of the current view controller
self.view.addSubview(navigationBar)
