MyCustomCell ,并在 cellForRowIndexPath tableview委托。当用户更改textfield值并调用 textFieldShouldEndEditing

然而,我想知道如何知道哪个textfield(indexPath)被更改了?

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"Cell";

    MyCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (cell == nil) 
    {  
        // use this if you created your cell with IB
        cell = [[[NSBundle mainBundle] loadNibNamed:@"MyCustomCell" owner:self options:nil] objectAtIndex:0];   

        // otherwise use this  
        cell = [[[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 


        // now set the view controller as the text field delegate  
        cell.textField.delegate = self;
    }

    // configure cell...

    return cell;
}

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

设置 UITextField cellForRowAtIndexPath 方法如果tableview中只有一个部分,则可以将该行设置为标记。这样地。

cell.textField.delegate = self;
cell.textField.tag = indexPath.row;

在你的 textFieldShouldEndEditing

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
    int row = textField.tag;

    [textField resignFirstResponder];
    return YES;
}

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField { if ([[[textField superview] superview] isKindOfClass:[MyCustomCell class]]) { MyCustomCell *cell = (MyCustomCell *)[[textField superview] superview]; NSIndexPath *indexPath = [self.tableView indexPathForCell:cell]; // this is what you want. } return YES; }

你可以试试这个:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"Cell";

    MyCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (cell == nil) 
    {  
        // use this if you created your cell with IB
        cell = [[[NSBundle mainBundle] loadNibNamed:@"MyCustomCell" owner:self options:nil] objectAtIndex:0];   

        // otherwise use this  
        cell = [[[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 


        // now set the view controller as the text field delegate  
        cell.textField.delegate = self;
        textField.tag = indexPath.Row;
    }

    // configure cell...

    return cell;
}

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
    NSLog("Selected Cell is:%@",textField.tag);
    [textField resignFirstResponder];
    return YES;
}
