UIToolbar xib xcode

问题

I am trying to create a custom UIToolbar that I can add to multiple views, I don't want to do this programmatically so I am using xib to design a UIToolbar. Do I need to wrap this in a UIView and a View Controller? ViewController.m is the root view controller. This is just a simple project I am just trying out some stuff

回答1:

You can do this so:

1. create ToolBar.xib file, delete UIView and add UIToolbar
2. create ToolBar.swift file, add code, like shown, and make outlets
3. for .xib in "Identity and Type" put Name "ToolBar.swift"

4. In your root View Controller put this code in ViewDidLoad:

   let toolBar = UINib(nibName: "ToolBar", bundle: nil).instantiateWithOwner(nil, options: nil).first as! ToolBar
   toolBar.hidden = true
   self.navigationController!.view.addSubview(toolBar)
   self.navigationController!.toolbarItems = toolBar.items
   

5. In all View Controllers put in ViewDidLoad:

   self.toolbarItems = self.navigationController!.toolbarItems
   

6. ToolBar.swift:

   import UIKit
   
   class ToolBar: UIToolbar {
   
       override init(frame: CGRect) {
           super.init(frame: frame)
       }
   
       required init?(coder aDecoder: NSCoder) {
           super.init(coder: aDecoder)
       }
   
       @IBAction func item1Pressed(sender: AnyObject) {
           print("item 1 pressed")
       }
   
       @IBAction func item2Pressed(sender: AnyObject) {
           print("item 2 pressed")
       }
   
       @IBAction func item3Pressed(sender: AnyObject) {
           print("item 3 pressed")
       }
   
       @IBAction func item4Pressed(sender: AnyObject) {
           print("item 4 pressed")
       }
   
   }
