iOS开发-cell里面有textField,出现键盘自动上移

Posted 2022-12-02 sunshine-zzz

当UITableViewCell里有UITextfield，当输入时键盘遮盖了UITextField，UITableView是会自动上移，当如果要让tableView自动滚动的话，还需要设置一下tableView的contentInset。接下来介绍一下实现步骤，  首先监听键盘出现和消失：  [[ NSNotificationCenter defaultCenter ] addObserver : self selector : @selector (keyboardWillShow:) name : UIKeyboardWillShowNotification object : nil ];     [[ NSNotificationCenter defaultCenter ] addObserver : self selector : @selector (keyboardWillHide:) name : UIKeyboardWillHideNotification object : nil ];
具体实现方法： -( void )keyboardWillShow:( NSNotification *)note     CGRect keyBoardRect=[note. userInfo [ UIKeyboardFrameEndUserInfoKey ] CGRectValue ];     self . myTableView . contentInset = UIEdgeInsetsMake ( 0 , 0 , keyBoardRect. size . height , 0 ); #pragma mark 键盘消失 -( void )keyboardWillHide:( NSNotification *)note     self . myTableView . contentInset = UIEdgeInsetsZero ;
