在設備iOS旋轉時發送動作

Question

這是我要實現的目標，它是發送有關設備旋轉的操作...

關鍵是我有一個360播放器，我希望僅在設備處於橫向狀態時才能開始播放視頻。 如果是縱向模式，我想顯示一條消息，說“橫向旋轉設備以開始播放”，當用戶旋轉設備時，將播放視頻。

下面是我到目前為止的代碼：

- (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");
}

}

此代碼的問題是，它僅在Sent Event中的TouchUp Inside上觸發。 。 。 無論如何要開始旋轉動作？

感謝你的幫助 ！

編輯 - -

還嘗試了以下內容：

- (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

你有沒有嘗試過

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

Answer 2

嘗試將您的代碼放入其中：

- (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{

}

並在UIViewController編寫此方法。 旋轉設備（實際上是接口）時將調用此方法。 如果要在旋轉接口之前執行某些操作，請使用willRotateFromInterfaceOrientation
