在重新加载UITableView部分时保持UIKeyboard

也请尝试以下代码.

[self.tblADMEDesign beginUpdates];
[self.tblADMEDesign insertRowsAtIndexPaths:@[selectedIndexPath] withRowAnimation:UITableViewRowAnimationRight];
[self.tblADMEDesign deleteRowsAtIndexPaths:@[selectedIndexPath] withRowAnimation:UITableViewRowAnimationNone];
[self.tblADMEDesign endUpdates];

[self.tblADMEDesign beginUpdates];
[self.tblADMEDesign endUpdates];

[self.tblADMEDesign beginUpdates];
[self.tblADMEDesign reloadRowsAtIndexPaths:@[selectedIndexPath] withRowAnimation:UITableViewRowAnimationNone];
[self.tblADMEDesign endUpdates];

推荐答案

此是在重新加载UITableView内容时保持键盘打开的最佳解决方案.

This is the best solution to keep the keyboard open while reload UITableView content.

如果它不适合您，那就不用担心.我有办法打开键盘.

If it is not worked for you then don't worry. I have a hack to open the keyboard as it.

请按照以下步骤操作，我相信它会为您工作.

Please follow the below steps, I am sure it will work for you.

• 将一个虚拟UITextField放入您的视图controller(Storyboard)
• 随意提供constraints(无关紧要)
• 始终从情节提要中保留隐藏的假人UITextField.
• 将隐藏的虚拟对象UITextField的outlet放入类文件.
• 现在在reloadData()之前进行黑客攻击的时间只需致电txtDummy.becomeFirstResponder()

• Take one dummy UITextField into your view controller(Storyboard)
• Give constraints as you like(Doesn't matter)
• Keep hidden dummy UITextField always from storyboard.
• Take outlet of hidden dummy UITextField into class file.
• Now time for the hack before reloadData() just call txtDummy.becomeFirstResponder()

请参阅下面针对已解决问题的代码.

Refer below code I have done to the resolved issue.

class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {

      @IBOutlet weak var txtDummy: UITextField!
        @IBOutlet weak var tblView: UITableView!

        override func viewDidLoad() {
            super.viewDidLoad()
            tblView.register(UINib.init(nibName: "CustomTableViewCell", bundle: nil), forCellReuseIdentifier: "CustomTableViewCell")
        }

        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return 10
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableView.dequeueReusableCell(withIdentifier: "CustomTableViewCell", for: indexPath) as! CustomTableViewCell
            cell.txtField?.text = "text"
            return cell
        }

        @IBAction func reloadtable(){
            txtDummy.becomeFirstResponder()
            tblView.reloadData()
            //Perform other operation after some delay
        }
    }
