怎样获得TableView中TextField.text？解决思路

怎样获得TableView中TextField.text？
tableView的cell中有TextField，怎样在导航离开此view或编辑完TextField时，获得TextField.text的值？

[解决办法]
UITableViewCell* cell = [self.utvLeft cellForRowAtIndexPath:indexPath];
if (cell != nil) 
{
TextField *field = (TextField*)[cell viewWithTag:CELL_TEXTFIELD];
｝
[解决办法]
吃饭去。写全部给你看看

C/C++ code

         UITextField *textField=[[UITextField alloc] initWithFrame:CGRectMake(250, 50, 150, 22)];        textField.tag=[indexPath row];        textField.delegate=self;        textField.placeholder = @"请输入";        textField.font = [UIFont fontWithName:@"Times New Roman" size:25];        [textField addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];        [cell addSubview:textField];//第二步,实现回调函数- (void) textFieldDidChange:(id) sender {    NSNumber *tag=[NSNumber numberWithInt:[sender tag]];    UITextField *_field = (UITextField *)sender;    NSLog(@"tag%@",tag);    NSLog(@"_field%@",[_field text]);}
