不要将光标传递到下一个文本字段而不在第一个文本字段中输入值 [英] Do not pass cursor to next textfield without entering value in first textfield

问题描述

我在 UITableView 中动态创建了文本字段我不想在没有在第一个文本字段中输入值的情况下传递光标

I have created textfields dynamically in UITableView I don't want to pass cursor without entering value in first textfield

[self.playerTable.subviews enumerateObjectsUsingBlock:^(id obj, NSUInteger idx,BOOL*stop)
 {
     UITableViewCell *cell = obj;

     if([cell isKindOfClass:[UITableViewCell class]])
     {
         for(UITextField *textField in cell.contentView.subviews)
         {
             if([textField isKindOfClass:[UITextField class]])
             {
                 if ([textField isFirstResponder])
                 {
                     [textField resignFirstResponder];

                     isEditMode = NO;
                     if(!isEditMode && [playerstr length] > 0)
                     {

                         NSMutableArray *playerinfoArry = [dbWrapper getPlayerInfo];
                         for (Playerinfo *player in playerinfoArry)
                         {
                             if ([player.playername isEqualToString:playerstr])
                             {
                                 isPlayerExist = YES;
                                 isEditMode = !isEditMode;
                                 CustomAlert *alert = [[CustomAlert alloc] initWithTitle:@"" message:@"Please choose a different name" delegate:nil cancelButtonTitle:nil otherButtonTitle:@""];
                                 [_nameField resignFirstResponder];
                                 [alert showInView:self.view];
                                 NSIndexPath *indexPath1=[NSIndexPath indexPathForRow:selectedRow inSection:0];

                                 [_playerTable selectRowAtIndexPath:indexPath1 animated:YES  scrollPosition:UITableViewScrollPositionTop];
                                 return;
                            }
                        }
                    }
                }
            }
        }
    }
}];

推荐答案

与其在尝试编辑另一个 UITextField 时寻找第一响应者，您是否尝试过另一种方法:不允许 UITextField 辞去第一响应者的职务.这可能类似于:

instead of looking for the first responder while trying to edit another UITextField, have you tried the other approach: not permitting the UITextField to resign as first responder. This could be something like:

 - (BOOL) textFieldShouldEndEditing:(UITextField *)textField{

        for(UITextField *otherTextField in self.view)
        {
            if ([otherTextField isKindOfClass:[UITextField class]] && [textField.text isEqualToString:otherTextField.text]){
                CustomAlert *alert = [[CustomAlert alloc] initWithTitle:@"" message:@"Please choose a different name" delegate:nil cancelButtonTitle:nil otherButtonTitle:@""];
                [alert showInView:self.view];
                return NO;
            }
        }
    return YES;

}
