iOS使用自定义TableView单元格prepareForSegue

Question

i created a .xib with my custom cell that I'm using on one of my tableviewcontroller in my storyboard.

In the storyboard, I linked the current tableview with another tableview with a push segue. (when the user click on one of the cell, he has a new view).

The problem is, I don't understand, how to "link" this segue, with my CUSTOM cell ?

I'm loading my custom cell like that :

static NSString *simpleTableIdentifier = @"cellCustom";

cellCustomView *cell = (cellCustomView *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

if (cell == nil) {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"cellCustom" owner:self options:nil];
    cell = [nib objectAtIndex:0];
}

and when I try to implement the method :

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    NSLog(@"test"); 
}

I've nothing, because according me, I missed something to do with my custom cell, and the segue of my storyboard, but I don't understand how it works :/

thx,

Answer 1

Did you try this?

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier:@"MySegue"
                              sender:self];
}

This method belong in whichever class contains the tableView. Make sure that the tableView's delegate is equal to self in that class. If you're using a storyboard, control-drag this view to whichever view you want to segue to. Click on that segue, and change its identifier to "MySegue" or whatever you want, as long as its the same in your code.

You can try the following approach

Control + Drag from your cell to next view controller to setup a segue called "showDetail", that you want to show on clicking tableview cell.

and in your view controller

if you have nsarray such as

NSArray *names = @[@"Apple", @"Google", @"Microsoft"];

and you want to pass the array value based on the selected table row cell index, you can as follows

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
   if ([[segue identifier] isEqualToString:@"showDetail"]) 
   {
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
        NSString *name = _names[indexPath.row]; 

        // For explanation sake, I am assuming name as property defined 
        // in your destination view controller
        [[segue destinationViewController] setName:name];  
    }
}
