Question

In my app there is a table view. When a row in the table view is selected a UIView appears and shows information.
The row title comes from a plist file with strings in it.
The plist file also includes strings with a phone number associated with the row title.
In the custom UIView I have a button, when you click the button I want it to call the number which is declared in the plist file.
The number which is associated with the row the user clicked.

How could I accomplish this?

The action is a ordinary IBAction:

- (IBAction)callNumber:(id)sender;

It is connected to the button in IB (in Xcode 4).

I would appreciate if someone had a solution to my problem, thanks.

Edit

For some clarity, I would like to get the phone number which is associated with the row you select in the table view. The string in the plist has a key, for the phone number name: “phone”.

NSString *phone = [[tableList objectAtIndex:indexPath.row] objectForKey:@"phone"];

“tablelist” is a NSMutableArray. I would like to get the key “phone” and store it in the NSString *phone. All this in a IBAction. Would it help to post the whole class?

You need to have a property on the “custom view” that indicates the index path of the row that was selected. You can put this in your custom view controller’s header to declare this property:

@interface MyCustomViewController : UIViewController {
    ...
    NSIndexPath * indexPath;
}
@property (nonatomic, retain) NSIndexPath * indexPath;

Then, setup the implementation like this:

@implementation MyCustomViewController
@synthesize indexPath;
...
// only needed if not using ARC
- (void)dealloc {
    self.indexPath = nil;
    ...
    [super dealloc];
}
@end

Now, in the tableView:didSelectRowAtIndexPath: method, simply create the view controller as usual, but set the indexPath property on it so that it can be accessed in the future:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    MyCustomViewController * vc = [[MyCustomViewController alloc] initWithBundle:nil nibName:nil];
    [vc setIndexPath:indexPath];
    [self presentModalViewController:vc];
    // if not using ARC
    [vc release];
}

Then, anywhere in MyCustomViewController.m, simply write self.indexPath.row to get the row of the index path that was selected.
