iPhone SDK：如何使用分段控制两个不同的TableView？

Question

I search some Similar question like this question Need approach to show tables using segmented control?

the solution is using single tableview

But I think my problem is a little different

because the view will have a segmented control,has two selection: "DHCP" and "Manually"

When I pressed "DHCP",there will be a grouped table under the segmented controller

This tableview is uneditable ,only shows 3 items(IP address,mask,Router)in each rows

But if pressed "Manually",the tableview will become editable

Only can type like row 1" IP Address : 169.95.192.1 ",row 2 " Subnet mask 255.255.255.0 "...

So my question is

<1>How to use segmented control to switch two different table ?

<2>How to create a editable tableview ?

great thanks for reading and reply this question.

Answer 1

right... well - you need to have a global BOOL eg BOOL isManual;

now in each of your UITableViewDatasource methods you need to check this bool:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }

    if(isManual){
        // set cell content for manual
    }
    else{
        //set cell content for DCHP
    }

    return cell;
}

// this function allows you to set a table view cell as editable
// look up UITableView delegate methods for more :)
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    if(isManual){
        return YES;
    }
    else{
        return NO;
    }
}

And similar.

Then in your segmented control callback method you want to change isManual and reloadData on your table:

- (void)segmentedControlChanged:(id)selector {
    UISegmentedControl *control = selector;
    int selected = [control selectedSegmentIndex];

    if(selected == 0){
            isManual == NO;
        }
        else{
            isManual == YES;
        }
    [self.tableView reloadData];
}

Hope that helps somewhat - although its rather vague. :)
