在设备iOS旋转时发送动作

Question

这是我要实现的目标，它是发送有关设备旋转的操作...

关键是我有一个360播放器，我希望仅在设备处于横向状态时才能开始播放视频。 如果是纵向模式，我想显示一条消息，说“横向旋转设备以开始播放”，当用户旋转设备时，将播放视频。

下面是我到目前为止的代码：

- (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");
}

}

此代码的问题是，它仅在Sent Event中的TouchUp Inside上触发。 。 。 无论如何要开始旋转动作？

感谢你的帮助 ！

还尝试了以下内容：

- (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

你有没有尝试过

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

Answer 2

尝试将您的代码放入其中：

- (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{

}

并在UIViewController编写此方法。 旋转设备（实际上是接口）时将调用此方法。 如果要在旋转接口之前执行某些操作，请使用willRotateFromInterfaceOrientation
