关闭带有inputAccessoryView的键盘

Question

textview停靠在底部（如消息应用程序）。但是，当用户点击textView外部时，键盘不会解散。

import UIKit 
class CommentsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 

    @IBOutlet var commentBar: UIView! 

    @IBOutlet var commentTextField: UITextField! 

    override var inputAccessoryView: UIView { 
     return commentBar 
    } 

    override func canBecomeFirstResponder() -> Bool { 
     commentBar.removeFromSuperview() 
     return true 
    } 

    func textFieldShouldReturn(textField: UITextField!) -> Bool { 
     self.view.endEditing(true); 
     return false; 
    } 

    override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { 
     self.view.endEditing(true); 
     commentTextField.resignFirstResponder() 
    }

无需在canBecomeFirstResponder方法中删除您的commentBar。这将在每次键盘退出时调用。

尝试一下这样的事情。

class ViewController: UIViewController { 
@IBOutlet var commentBar: UIView! 
@IBOutlet var commentTextField: UITextField! 

override func viewDidLoad() { 
     super.viewDidLoad() 
     commentBar.removeFromSuperview() 
    } 
override var inputAccessoryView: UIView { 
     return commentBar 
    } 

override func canBecomeFirstResponder() -> Bool { 
     return true 
    } 

    func textFieldShouldReturn(textField: UITextField!) -> Bool { 
     self.view.endEditing(true); 
     return false; 
    } 

    override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { 
     self.view.endEditing(true); 
     commentTextField.resignFirstResponder() 
    } 

}
