I'm looking for an example of how to create an animated row menu like the Facebook & twitter apps for iphone have. I see the TTTableViewController
has the showMenu:forCell:
method, but I have not been able to find any examples of how to use it. Specifically in the context of a URL Navigator selector, but any example would be great.

Were you able to find an example on this.
I, too, was stuck with the same problem as you did. I couldn't find an example of using TTTableViewController showMenu:forCell: method a week ago. After messing with the code, I came up with this...
Create a subclass of TTTableViewCell and add a UIButton (as a trigger to launch the menu view) to the view.
@interface MyViewCell : TTTableViewCell {
}
- (id) initWithName:(NSString *)name target:(id)target action:(SEL)action {
// ...
UIButton *moreButton = [UIButton buttonWithType:UIButtonTypeCustom];
moreButton.frame = CGRectMake(268.0f, 6.0f, 32.0f, 32.0f);
[moreButton setImage:TTIMAGE(@"bundle://Icon_More.png")
forState:UIControlStateNormal];
[moreButton addTarget:target action:action
forControlEvents:UIControlEventTouchUpInside];
[self moreButton];
// ...
}
Next, create a subclass of TTTableViewController and add custom TTTableViewCells to the data source.
@interface MyTableViewController : TTTableViewController {
}
- (void) createModel {
self.dataSource = [TTListDataSource dataSourceWithObjects:
[[[ContactViewCell alloc] initWithName:@"Cell 1"
target:self
action:@selector(moreButtonDidPress:)]
autorelease],
[[[ContactViewCell alloc] initWithName:@"Cell 2"
target:self
action:@selector(moreButtonDidPress:)]
autorelease],
nil];
}
In the action handler, that's where showMenu:forCell: is called. The trick is to determine which cell the button belongs to and consequently replace that cell with the menu view. This is what I did.
- (void) moreButtonDidPress:(id)sender {
// Load our custom menu view from a nib.
UIView *menuView = [[UIView alloc] initWithFrame:cell.contentView];
UIButton *moreButton = (UIButton *) sender;
// Convert plusButton bounds to the the coordinate system of table view
// and then get the cell containing the button.
CGRect coord = [plusButton convertRect:moreButton.bounds toView:self.tableView];
NSIndexPath *path = [self.tableView indexPathForRowAtPoint:coord.origin];
TTTableViewCell* cell = (TTTableViewCell*) [self.tableView
cellForRowAtIndexPath:path];
// Now call showMenu with the menu to display on the associated cell.
[self showMenu:menuView forCell:cell animated:YES];
}
It's not exactly using a URL Navigator selector, but it's functional.
