Ios 当单元格不可见时，如何访问和迭代UITableView中的contentView.SubView？

我正在UITableView中创建一个表单，当我使用for（UIView*view in cell.contentView.subviews）{}收集表中的所有数据时，即使它遍历UITableView中的每个单元格，它也看不到行中任何尚不可见的数据。如何访问此数据

我尝试添加ScrollToRowatineXpath，但徒劳地希望它能够加载可见的行，但没有效果

 for (int i=0; i < countArray.count; i++) { //count needs to be for the cells entire tableView

        NSIndexPath *indexPath = [NSIndexPath indexPathForRow: i inSection: 0]; //create NSIndexPath for each cell in section 0
        UITableViewCell *cell = [self.table cellForRowAtIndexPath:indexPath]; //iterating through each cell available in table
        NSLog(@"iterationing through cell \"%i\"",indexPath.row);

         [self.table scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
        NSLog(@"moving view to \"%i\"",indexPath.row);

        for (UIView *view in  cell.contentView.subviews){ //find views within cell.contentview

            if ([view isKindOfClass:[UITextField class]]){ // narrow those views down to anything with class UITextField

                UITextField* txtField = (UITextField *)view; // instantiate the UITextField

                if (txtField.tag == 201) { //find the tag of the instantiated UITextField
                    if (dataSwitch == 0) { //we are collecting data
                        [tmpArray addObject:[NSString stringWithFormat:@"%@",txtField.text]];
                    }else if (dataSwitch == 1) { //we are distributing data
                        txtField.text = [tmpArray objectAtIndex:i];
                    }
                }
                else if (txtField.tag == 202) { //find the tag of the instantiated UITextField
                    if (dataSwitch == 0) { //we are collecting data
                        [tmpArray addObject:[NSString stringWithFormat:@"%@",txtField.text]];
                    }else if (dataSwitch == 1) { //we are distributing data
                        txtField.text = [tmpArray objectAtIndex:i];
                    }
                }
                else if (txtField.tag == 203) { //find the tag of the instantiated UITextField
                    if (dataSwitch == 0) { //we are collecting data
                        [tmpArray addObject:[NSString stringWithFormat:@"%@",txtField.text]];
                    }else if (dataSwitch == 1) { //we are distributing data
                        txtField.text = [tmpArray objectAtIndex:i];
                    }
                }
                else if (txtField.tag == 204) { //find the tag of the instantiated UITextField
                    if (dataSwitch == 0) { //we are collecting data

在此方面的任何帮助都将不胜感激

这就是我最后做的

邓肯C是对的，像这样获取信息是不对的。可以设置tableview的动画，以将可重用的单元格带入视图并收集数据，但它看起来很混乱，这是一种更干净的方法

-(void)textFieldDidEndEditing:(UITextField *)textField {

 if(textField.tag >= 0 && textField.tag <= 10) {

      CGPoint location = [self.table convertPoint:textField.frame.origin fromView:textField.superview];
        NSIndexPath *indexPath = [self.table indexPathForRowAtPoint:location]; //get the indexPath of the textField.

      NSString *str1  = [NSString stringWithFormat:@"%i",stack];
      NSString *str2  = [NSString stringWithFormat:@"%i",indexPath.row];
      NSString *str3  = [NSString stringWithFormat:@"%@",textField.text];

      NSMutableArray *cellAnswer = [[NSMutableArray alloc] initWithObjects:str1,str2,str3, nil];

    }
}
