在UIWebView中横向模式的Youtube视频 [英] Youtube video in landscape mode within a UIWebView

问题描述

我的应用程序不适用于景观。但是当我在 UIWebView 中打开我的YouTube频道并且用户启动视频时，它会显示在肖像中。如果用户转动他的iPhone，我想让它以横向模式显示。

如何启用横向模式，就像这种情况一样？ / p>

我知道有脏黑客这样做，但我更喜欢更干净的东西。此外，我不希望UIWebView切换到横向，但只是视频可以。

解决方案

我终于调整了我的查看以便使用以下代码支持横向模式：

   - （void）viewDidLoad {
 [super viewDidLoad] ; 
 
 [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; 
 [[NSNotificationCenter defaultCenter] addObserver：self selector：@selector（orientationChanged :) 
 name：UIDeviceOrientationDidChangeNotification object：nil]; 
} 
 
  - （void）viewWillAppear：（BOOL）animated {
 UIDeviceOrientation deviceOrientation = [UIDevice currentDevice] .orientation; 
 if（UIDeviceOrientationIsLandscape（deviceOrientation））
 {
 //我为此方向设置了我的新框架原点和大小
 isShowingLandscapeView = YES; 
} 
 else if（deviceOrientation == UIDeviceOrientationPortrait）
 {
 //我为此方向设置了我的新框架原点和大小
 isShowingLandscapeView = NO; 
} 
} 
 
  - （无）orientationChanged：（NSNotification *）通知
 {
 //我们必须在此添加延迟，否则我们' ll在新视图中交换
 //太快了，我们将得到一个动画故障
 [self performSelector：@selector（updateLandscapeView）withObject：nil afterDelay：0]; 
} 
 
  - （void）updateLandscapeView 
 {
 UIDeviceOrientation deviceOrientation = [UIDevice currentDevice] .orientation; 
 if（UIDeviceOrientationIsLandscape（deviceOrientation）&&！isShowingLandscapeView）
 {
 //我为此方向设置了我的新框架原点和大小
 isShowingLandscapeView = YES; 
} 
 else if（deviceOrientation == UIDeviceOrientationPortrait&& isShowingLandscapeView）
 {
 //我为此方向设置了我的新框架原点和尺寸
 isShowingLandscapeView = NO; 
} 
} 
 
  - （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation 
 {
 return（interfaceOrientation == UIInterfaceOrientationPortrait || UIInterfaceOrientationIsLandscape（interfaceOrientation）） ; 
} 
  

My application was not made ​​for the landscape. But when I open my YouTube channel in a UIWebView and a user launches a video, it appears in Portrait. I would like to make it appear in landscape mode if the user rotate his iPhone.

How to enable landscape mode as in this case?

I know there are "dirty hacks" to do this but I prefer something cleaner. Also I do not want the UIWebView switches to landscape but just that the videos can.

解决方案

I finally adjusted my view so that it supports landscape mode using the following code :

- (void)viewDidLoad {
    [super viewDidLoad];

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:)
                                                 name:UIDeviceOrientationDidChangeNotification object:nil];
}

- (void)viewWillAppear:(BOOL)animated {
    UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
    if (UIDeviceOrientationIsLandscape(deviceOrientation))
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = YES;
    }
    else if (deviceOrientation == UIDeviceOrientationPortrait)
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = NO;
    }
}

- (void)orientationChanged:(NSNotification *)notification
{
    // We must add a delay here, otherwise we'll swap in the new view
    // too quickly and we'll get an animation glitch
    [self performSelector:@selector(updateLandscapeView) withObject:nil afterDelay:0];
}

- (void)updateLandscapeView
{
    UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
    if (UIDeviceOrientationIsLandscape(deviceOrientation) && !isShowingLandscapeView)
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = YES;
    }
    else if (deviceOrientation == UIDeviceOrientationPortrait && isShowingLandscapeView)
    {
        //I set my new frame origin and size here for this orientation
        isShowingLandscapeView = NO;
    }    
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait || UIInterfaceOrientationIsLandscape(interfaceOrientation));
}
