Send Action on rotation of device iOS - ios

Question

here is what I'm trying to achieve, it would be to send an action on rotation of the device...
the point is i'm having a 360 player, I would like the video to start only once the device is on landscape. If it's in portrait i'd like to display a message a saying "rotate your device in landscape to start", and when the user rotate the device, the video play.
below is my code so far:
- (IBAction)test:(id)sender forEvent:(UIEvent *)event {
if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft || [[UIDevice currentDevice] orientation ]== UIDeviceOrientationLandscapeRight)
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"demo1" ofType:#"mp4"];
NSURL *url = [NSURL fileURLWithPath:path];
Video360ViewController *videoController = [[Video360ViewController alloc] initWithNibName:#"HTY360PlayerVC" bundle:nil url:url];
[videoController VRMode:true];
if (![[self presentedViewController] isBeingDismissed]) {
[self presentViewController:videoController animated:YES completion:nil];
}
}
if([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait || [[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown )
{
NSLog(#"UIDeviceOrientationPortrait");
}
}
The problem of this code is than it trigger only on TouchUp Inside in the Sent Event . . . anyway to have the action starting on rotation ?
Thanks for all your help !
EDIT---
TRYIED THE FOLLOWING ASWELL:
- (IBAction)test:(id)sender forEvent:(UIEvent *)event {
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft || [[UIDevice currentDevice] orientation ]== UIDeviceOrientationLandscapeRight)
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"demo1" ofType:#"mp4"];
NSURL *url = [NSURL fileURLWithPath:path];
Video360ViewController *videoController = [[Video360ViewController alloc] initWithNibName:#"HTY360PlayerVC" bundle:nil url:url];
[videoController VRMode:true];
if (![[self presentedViewController] isBeingDismissed]) {
[self presentViewController:videoController animated:YES completion:nil];
}
}
if([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait || [[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown )
{
NSLog(#"UIDeviceOrientationPortrait");
}
}

Answer 1

Have you tried
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

Answer 2

Try put your code inside:
- (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
}
and write this methods in your UIViewController. This method is called when the device (interface really) is rotated; if you want do something before the rotation of interface, use willRotateFromInterfaceOrientation
