iOS handoff from phone to macbook safari/chrome - ios

Question

I want to send a URL from my app to open on a laptop web browser using handoff. I have added the activity type to my app's NSUserActivityTypes. here is my code so far:
- (void)startHandoff {
NSUserActivity *activity = [[NSUserActivity alloc] initWithActivityType:#"com.me.browse"];
activity.webpageURL = [NSURL URLWithString:_wakeUrl];
[activity becomeCurrent];
}
It doesn't seem to be appearing on my dock - does it need a special Activity Type if you want to use safari?

Ok after tests, it seems that you need to declare the NSUserActivity as a instance Variable :
So this does not work:
#interface TestViewController () {
}
#end
#implementation TestViewController
- (void)viewDidLoad {
[super viewDidLoad];
//init hand off
NSUserActivity *activity = [[NSUserActivity alloc] initWithActivityType:#"com.app.browse"];
activity.webpageURL = [NSURL URLWithString:#"http://www.stackoverflow.com"];
[activity becomeCurrent];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
But this works fine:
#interface TestViewController () {
NSUserActivity *activity;
}
#end
#implementation TestViewController
- (void)viewDidLoad {
[super viewDidLoad];
//init hand off
activity = [[NSUserActivity alloc] initWithActivityType:#"com.app.browse"];
activity.webpageURL = [NSURL URLWithString:#"http://www.stackoverflow.com"];
[activity becomeCurrent];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
Not sure why though, I'm looking into it now
