如何在特定的indexpath的tableview中的单元格中插入值？

Question

我在tableview中有一个标签和textfield，现在我想要的是无论我插入textfieldDidEditing方法中的值，它都应该计算该值并将其返回给tablevievw的indexpath中的标签。

Answer 1

在textfieldDidEditing，就可以得到相应的文本框的单元格，计算值，并将其分配给标签如下：

yourTableViewCell *cell = (yourTableViewCell *)[[textField superview] superview]; 
cell.yourLabel.text = value; 

Answer 2

/* u just give Tag to TextField and in textFieldDidEndEditing, save textfield text into an string and then reload the row...here is the code..also have sample */ 


-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexpath 
{ 
    UITableViewCell *cell = [[UITableViewCell alloc] init]; 

    UITextField *txtField1 = [[UITextField alloc]initWithFrame:CGRectMake(20, 10, 100, 80)]; 
    txtField1.tag = indexpath.row; 
    txtField1.delegate= self; 
    [cell addSubview:txtField1]; 

    UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(140, 10, 100, 80)]; 

    [cell addSubview:label1]; 

    //set text in label ** str1 comes from textFieldDidEndEditing 
    label1.text = str1; 

    return cell; 
} 

-(void)textFieldDidEndEditing:(UITextField *)textField 
{ 
    //save textField text to any string**declair it global 
    str1 = textField.text; 

    //reload selected row in table 
    NSIndexPath *durPath = [NSIndexPath indexPathForRow:textField.tag inSection:0]; 
    NSArray *paths = [NSArray arrayWithObject:durPath]; 
    [tbl reloadRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationRight]; 
}
