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？

------解决方案--------------------
UITableViewCell* cell = [self.utvLeft cellForRowAtIndexPath:indexPath];
if (cell != nil)
{
TextField *field = (TextField*)[cell viewWithTag:CELL_TEXTFIELD];
｝
------解决方案--------------------
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]);
}
