如何隐藏键盘，当UITextFiled在UITableViewCell中时

@interface ViewController () {   UITextField *_textFieldBeingEdited;} @end- (void)textFieldDidBeginEditing:(UITextField *)textField {   _textFieldBeingEdited = textField;}- (void)textFieldDidEndEditing:(UITextField *)textField{   // no need to resignFirstResponder here.   _textFieldBeingEdited = nil;}- (void)tableView:(UITableView *)tableView           didSelectRowAtIndexPath:(NSIndexPath *)indexPath {   if (_textFieldBeingEdited) {     [_textFieldBeingEdited resignFirstResponder];   }   ...}
