如何將barButtonItem添加到工具欄中

Question

如何將此代碼轉換爲讓按鈕出現在工具欄中？ ：

navigationItem.rightBarButtonItem = editButtonItem() 

Answer 1

試試這個，

let barButtonItem = UIBarButtonItem(title: "Edit", style: .Plain, target: self, action: "onEditButtonTapped:") 
    self.navigationItem.rightBarButtonItem = barButtonItem 

然後寫入動作功能喜歡這個，

func onEditButtonTapped(sender:UIBarButtonItem) { 
     ... 
    }

試試這個：

self.navigationItem.setRightBarButtonItem(UIBarButtonItem(barButtonSystemItem: UIBarButtonItemStyle.Plain, target: self, action: "btnClicked:"), animated: true) 


    //adding function to bar button 

    func btnClicked(sender: UIBarButtonItem) 
    { 
     //your code here 
    }
