这是通过UIViewController
将您的文字用作UIViewController
的输入附件视图,因此请从情节提要中删除该底部视图
在视图控制器中添加以下内容
var viewAcc: UIView?
var sendButton: UIButton!
var inputTextField: UITextField!
override var inputAccessoryView: UIView? {
return viewAcc
}
override var canBecomeFirstResponder: Bool {
return true
}
在视图中加载方法添加以下代码
注意:请根据您的要求更改约束
viewAcc = UIView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 44))
viewAcc?.backgroundColor = UIColor.white
inputTextField = UITextField (frame: CGRect(x:8, y:0, width:UIScreen.main.bounds.width, height: 44 ))
inputTextField.inputAccessoryView = nil
inputTextField.delegate = self as? UITextFieldDelegate
inputTextField.placeholder = "Enter message..."
viewAcc?.backgroundColor = .white
viewAcc?.addSubview(inputTextField);
let topBorderView = UIView()
topBorderView.backgroundColor = UIColor(white: 0.5, alpha: 0.5)
viewAcc?.addSubview(topBorderView)
viewAcc?.addConstraintsWithFormat(format: "H:|[v0]|", views: topBorderView)
viewAcc?.addConstraintsWithFormat(format: "V:|[v0(0.5)]", views: topBorderView)
sendButton = UIButton(type: .system)
sendButton.isEnabled = true
sendButton.titleLabel?.font = UIFont.systemFont(ofSize: 16)
sendButton.setTitle("Send", for: .normal)
sendButton.contentEdgeInsets = UIEdgeInsets(top: 8, left: 8, bottom: 8, right: 8)
sendButton.addTarget(self, action: #selector(handleSend), for: .touchUpInside)
viewAcc?.addSubview(sendButton)
inputTextField.translatesAutoresizingMaskIntoConstraints = false
sendButton.translatesAutoresizingMaskIntoConstraints = false
viewAcc?.addConstraint(NSLayoutConstraint(item: inputTextField, attribute: .left, relatedBy: .equal, toItem: viewAcc, attribute: .left, multiplier: 1, constant: 8))
viewAcc?.addConstraint(NSLayoutConstraint(item: inputTextField, attribute: .top, relatedBy: .equal, toItem: viewAcc, attribute: .top, multiplier: 1, constant: 7.5))
viewAcc?.addConstraint(NSLayoutConstraint(item: inputTextField, attribute: .right, relatedBy: .equal, toItem: sendButton, attribute: .left, multiplier: 1, constant: -2))
viewAcc?.addConstraint(NSLayoutConstraint(item: inputTextField, attribute: .bottom, relatedBy: .equal, toItem: viewAcc, attribute: .bottom, multiplier: 1, constant: -8))
viewAcc?.addConstraint(NSLayoutConstraint(item: sendButton, attribute: .right, relatedBy: .equal, toItem: viewAcc, attribute: .right, multiplier: 1, constant: 0))
viewAcc?.addConstraint(NSLayoutConstraint(item: sendButton, attribute: .bottom, relatedBy: .equal, toItem: viewAcc, attribute: .bottom, multiplier: 1, constant: -4.5))
Goto Storyboard选择你的tableview并将键盘关闭模式设置为交互式
现在你可以用手指拖动来解除键盘和文本字段
编辑IPHONE X支持
lazy var viewAcc: SafeAreaInputAccessoryViewWrapperView = {
return SafeAreaInputAccessoryViewWrapperView(for: button)
}()
