How do make the individual cells go to different View Controller. Right now, using the method im using, if i click the first cell, it takes me to a view controller where i have a pic. now if i go back and click the second cell, it takes me to the same view controller. How do i change this so that all the other individual cells go to individual view controller? what do i add or what do i configure?
here my code:
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableV开发者_StackOverflow中文版iewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSUInteger row = [indexPath row];
cell.textLabel.text = [breakdownArray objectAtIndex:row];
bookDetailViewController.title = [NSString stringWithFormat:@"%@" , [breakdownArray objectAtIndex:row]];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.
/*
<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
*/
NSInteger row = [indexPath row];
if (self.bookDetailViewController == nil); {
BookDetailViewController *aBookDetail = [[BookDetailViewController alloc] initWithNibName:@"BookDetailView" bundle:nil];
self.bookDetailViewController = aBookDetail;
[aBookDetail release];
}
bookDetailViewController.title = [NSString stringWithFormat:@"%@" , [breakdownArray objectAtIndex:row]];
Books2010AppDelegate *delegate = [[UIApplication sharedApplication] delegate];
[delegate.breakdownNavController pushViewController:bookDetailViewController animated:YES];
}
One fairly easy way is in your tableView:didSelectRowAtIndexPath: method. You can check the index path parameter and execute different code paths. Something like:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath )indexPath {
switch(indexPath.row) {
case 1:
[self.navigationController pushViewController:someViewController animated:YES];
break;
case 2:
[self.navigationController pushViewController:someOtherViewController animated:YES];
break;
}
}
Like most design choices, this is just an example of one possible approach. That's the best I can do in this general case.
I would create a new view controller each time instead of using the same one and just changing its properties, more like the example that you have commented out in tableView:didSelectRowAtIndexPath:. This will only work if you don't access your controller from anywhere other than these methods.
First: Remove bookDetailViewController.title = [NSString stringWithFormat:@"%@" , [breakdownArray objectAtIndex:row]];
from your tableView:cellForRowAtIndexPath: method (you should do this anyway, since it is just taking more processor time)
Second: Remove the bookDetailController property from your class. You won't need it anymore.
Third: Implement tableView:didSelectRowAtIndexPath: as follows:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)path {
BookDetailViewController *bookDetailViewController = [[BookDetailViewController alloc] initWithNibName:@"BookDetailView" bundle:nil];
NSInteger row = path.row;
bookDetailViewController.title = [NSString stringWithFormat:@"%@" , [breakdownArray objectAtIndex:row]];
//Any other setup on view controller
Books2010AppDelegate *delegate = [[UIApplication sharedApplication] delegate];
[delegate.breakdownNavController pushViewController:bookDetailViewController animated:YES];
[bookDetailViewController release];
}
