Answer 1

You should try this.

//check if the device supports 3DTouch
if(self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable){
    [self registerForPreviewingWithDelegate:self sourceView:self.view];
}else{
    [[[UIAlertView alloc] initWithTitle:@"Error" message:@"3DTouch not available" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil] show];
}
