系统忽略iPhone旋转

发布于 2024-09-09 06:24:19 字数 1288 浏览 6 评论 0原文

UIApplication 中是否有像 beginIgnoringInteractionEvents 这样的函数忽略旋转而不是触摸？我需要我的应用程序不只在我呈现的 MPMovePlayerViewController 中旋转。

谢谢

[更新]

这是我的代码——

MPMoviePlayerViewController *mpViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:videoURL]];
[mpViewController shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
[self presentMoviePlayerViewControllerAnimated:mpViewController];
[mpViewController release];

我通过添加 shouldAutorotateToInterfaceOrientation: 和 setStatusBarOrientation: 方法使其工作。它在模拟器中工作。但是，如果我在视频播放时旋转 iPhone，状态栏也会旋转并保持“卡在”纵向状态。

[更新2]

通过子类化MPMoviePlayerViewController（并实现shouldAutorotate方法），程序可以按预期旋转。只有视频无法播放，因为该行

[self presentMoviePlayerViewControllerAnimated:mpViewController];

不接受我的子类。

“警告：不兼容的 Objective-C 类型 'struct NoRotate *'，当从不同的 Objective-C 类型传递 'presentMoviePlayerViewControllerAnimated:' 的参数 1 时，预期为 'struct MPMoviePlayerViewController *'”

Is there a function like beginIgnoringInteractionEvents in UIApplication that ignores rotation instead of touches? I need my app NOT to rotate just in an MPMovePlayerViewController that I present.

Thanks

[UPDATE]

Here's my code --

MPMoviePlayerViewController *mpViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:videoURL]];
[mpViewController shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
[self presentMoviePlayerViewControllerAnimated:mpViewController];
[mpViewController release];

I got it working by adding both the shouldAutorotateToInterfaceOrientation: and setStatusBarOrientation: methods. It works in the simulator. However if I rotate the iPhone while the video is playing, the status bar rotates as well and stays 'stuck' in the portrait orientation.

[UPDATE 2]

By subclassing MPMoviePlayerViewController (and implementing the shouldAutorotate method), the program rotates as it should. Only the video doesn't play because the line

[self presentMoviePlayerViewControllerAnimated:mpViewController];

doesn't accept my subclass.

"warning: incompatible Objective-C types 'struct NoRotate *', expected 'struct MPMoviePlayerViewController *' when passing argument 1 of 'presentMoviePlayerViewControllerAnimated:' from distinct Objective-C type"

在您呈现的视图中，实现 shouldAutoRotate 方法并简单地返回“NO”。这将导致手机忽略任何和所有方向变化。

也许你可以像这样子类化 MPMoviePlayerViewController

// NotRotatingMoviePlayerViewController.h
@interface NotRotatingMoviePlayerViewController : MPMoviePlayerViewController {
}

@end

// NotRotatingMoviePlayerViewController.m
@implementation

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
  return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

@end

Maybe you could subclass the MPMoviePlayerViewController like this

// NotRotatingMoviePlayerViewController.h
@interface NotRotatingMoviePlayerViewController : MPMoviePlayerViewController {
}

@end

// NotRotatingMoviePlayerViewController.m
@implementation

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
  return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

@end
