iOS rightBarButtonItem on UINavigationController in swift
提问by Marcone
I'm trying to put a rightBarButtonItemon a second view controller of an UINavigationViewControllerstack.
我正在尝试将一个rightBarButtonItem放在UINavigationViewController堆栈的第二个视图控制器上。
I'm creating and setting the button in viewDidLoadof the view controller that I want to show. My actual code looks like this:
我正在创建和设置viewDidLoad要显示的视图控制器的按钮。我的实际代码如下所示：
override func viewDidLoad() {
super.viewDidLoad()
menu_button_ = UIBarButtonItem(image: UIImage(named: "menu"),
style: UIBarButtonItemStyle.Plain ,
target: self, action: "OnMenuClicked:")
self.navigationController!.navigationItem.rightBarButtonItem = menu_button_
}
What am I missing? The button doesn't appear.
我错过了什么？按钮不出现。

You should set the menu_button_as the rightBarButtonItemof your viewControllerrather than the navigationController.
您应该将 设置menu_button_为rightBarButtonItem您的viewController而不是navigationController。
Try
尝试
self.navigationItem.rightBarButtonItem = menu_button_
instead of
代替
self.navigationController!.navigationItem.rightBarButtonItem = menu_button_

let homeButton : UIBarButtonItem = UIBarButtonItem(title: "LeftButtonTitle", style: UIBarButtonItemStyle.Plain, target: self, action: "")

self.navigationItem.leftBarButtonItem = homeButton
self.navigationItem.rightBarButtonItem = logButton

button.layer.cornerRadius = 5
button.backgroundColor = .gray
button.frame = CGRect(x: 0, y: 0, width: 100, height: 25)

In Swift 5
在斯威夫特 5
//For righter button item
let rightBtn = UIBarButtonItem(image: UIImage(named: "rightmenu"), style: .plain, target: self, action: #selector(onClickMethod))//Change your function name and image name here
self.navigationItem.rightBarButtonItem = rightBtn
//self.navigationItem.rightBarButtonItem = [rightBtn, anotherBtn] //If you want to add more buttons add like this
//This is your function
@objc func onClickMethod() {
print("Left bar button item")
}
