我有UITableView與嵌入UICollectionView。在第一部分中有用UITextField定製的單元格,第二部分有UICollectionView。UITableView中的UICollectionView不檢測tap因爲view.addGestureRecognizer()
要隱藏鍵盤,當用戶敲擊的UITextField之外我使用
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard))
view.addGestureRecognizer(tap)
func dismissKeyboard(sender: UIGestureRecognizer) {
view.endEditing(true)
}
因爲它的,因爲我已經想通了,我UICollectionView不對其物品識別水龍頭。如果我刪除view.addGestureRecognizer(tap)一切工作正常,但在這種情況下鍵盤不隱藏。
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder() //if desired
return true
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
switch indexPath.section {
case 0:
let cell = tableView.dequeueReusableCell(withIdentifier: "ProfileTableViewCell", for: indexPath) as! ProfileTableViewCell
cell.value.delegate = self // value is my textField
return cell
case 1:
let cell = tableView.dequeueReusableCell(withIdentifier: "WallpaperTableViewCell", for: indexPath) as! WallpaperTableViewCell
cell.setCollectionViewDataSourceDelegate(dataSourceDelegate: self, index: (indexPath as NSIndexPath).row)
return cell
default:
let cell = UITableViewCell()
return cell
}
}
如何解決這個問題,並一起使用隱藏鍵盤和點擊識別UICollectionView? 感謝
要嵌入UICollectionView中的UITableView我用這個例子https://github.com/DahanHu/DHCollectionTableView

答案是很簡單
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
和
func keyboardWillShow(notification: NSNotification) {
view.addGestureRecognizer(tap)
}
func keyboardWillHide(notification: NSNotification) {
view.removeGestureRecognizer(tap)
}
