Question

我正在使用UIWebView使用iFrame播放YouTube视频我正在使用UIMoviePlayerControllerDidEnterFullscreenNotification将youtube屏幕检测到全屏如下代码：

[[NSNotificationCenter defaultCenter] addObserver: self
                                         selector: @selector(myMovieEnterFullScreen:)
                                             name: @"UIMoviePlayerControllerDidEnterFullscreenNotification"
                                           object: nil];

适用于iOS7 但我尝试在iOS8中运行它它不起作用。
我认为通知名称已经更改有没有办法在ios8中检测youtube全屏事件？

Answer 1

markussvensson的实施有一些误报，因为任何UIWindowDidBecomeVisibleNotification都被认为是全屏视频播放，但事实并非如此。

实施＆＃34; AVPlayerItemBecameCurrentNotification＆＃34;通过Selvin可以捕捉电影播放开始，但无法捕捉电影播放停止。

所以我结合了两种实现，它按预期工作。

将观察者添加到AVPlayerItemBecameCurrentNotification＆amp; UIWindowDidBecomeHiddenNotification;
当AVPlayerItemBecameCurrentNotification发生时，设置一个标志;
当UIWindowDidBecomeHiddenNotification发生时，请检查该标记是否为＆＃34;视频停止播放事件＆＃34;。

BTW，AVPlayerItemBecameCurrentNotification未记录，可能会在下一个iOS主要版本中被破坏。

Answer 2

我有同样的问题。我找不到真正的解决方案，但我能够使用UIWindowDidBecomeVisibleNotification / UIWindowDidBecomeHiddenNotification通知解决它。

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(windowVisible:)
                                             name:UIWindowDidBecomeVisibleNotification
                                           object:self.view.window];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(windowHidden:)
                                             name:UIWindowDidBecomeHiddenNotification
                                           object:self.view.window];

- (void)windowVisible:(NSNotification *)notification
{
    NSLog(@"-windowVisible");
}

- (void)windowHidden:(NSNotification *)notification
{
    NSLog(@"-windowHidden");
}

Answer 3

我同意@markussvensson。我确认iOS8上没有发布UIMoviePlayerControllerDidEnterFullscreenNotification。

或者，您可以观察AVPlayerItemBecameCurrentNotification以查看YouTube视频是否全部来自UIWebView。

检查我是否在NSNotificationCenter上写了一个钩子，以观察在视频播放过程中传递的所有通知。

#import "NSNotificationCenter+Hook.h"
#import <objc/runtime.h>

@implementation NSNotificationCenter (Hook)

+ (void)load
{
    Method original = class_getInstanceMethod([NSNotificationCenter class], @selector(postNotificationName:object:userInfo:));
    Method swizzled = class_getInstanceMethod([NSNotificationCenter class], @selector(swizzle_postNotificationName:object:userInfo:));

    method_exchangeImplementations(original, swizzled);

    original = class_getInstanceMethod([NSNotificationCenter class], @selector(postNotificationName:object:));
    swizzled = class_getInstanceMethod([NSNotificationCenter class], @selector(swizzle_postNotificationName:object:));

    method_exchangeImplementations(original, swizzled);

    original = class_getInstanceMethod([NSNotificationCenter class], @selector(postNotification:));
    swizzled = class_getInstanceMethod([NSNotificationCenter class], @selector(swizzle_postNotification:));

    method_exchangeImplementations(original, swizzled);
}

- (void)swizzle_postNotificationName:(NSString *)aName object:(id)anObject userInfo:(NSDictionary *)aUserInfo{

    NSLog(@"HOOK_NOTIFICATION_With_UserInfo: %@",aName);
    [[NSNotificationCenter defaultCenter]swizzle_postNotificationName:aName object:anObject userInfo:aUserInfo];

}

- (void)swizzle_postNotificationName:(NSString *)aName object:(id)anObject{
    NSLog(@"HOOK_NOTIFICATION_Without_UserInfo: %@",aName);
    [[NSNotificationCenter defaultCenter]swizzle_postNotificationName:aName object:anObject];
}

- (void)swizzle_postNotification:(NSNotification *)notification
{
    NSLog(@"HOOK_NOTIFICATION_NSNotification: %@",notification.name);
    [[NSNotificationCenter defaultCenter]swizzle_postNotification:notification];
}

@end

播放器全屏时记录数据

Answer 4

我尝试使用下面的代码来查找备用通知名称。

NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
[center addObserverForName:nil
                    object:nil
                     queue:nil
                usingBlock:^(NSNotification *notification)
{
     NSLog(@"%@", notification.name);
}];

但没有找到。
现在我正在使用HCYoutubeParser来获取直接视频网址并通过MPMoviePlayerController播放但这很危险。
您不知道Google什么时候更改直接网址的规则。

Answer 5

你以错误的方式解决这个问题。

不是将整个应用程序限制为纵向，然后尝试使视频播放器允许横向，而是应该允许整个应用程序中的横向，然后将您的视图控制器（或根视图控制器）限制为仅允许纵向模式，像这样：

在目标设置中，允许应用的横向显示：

在视图控制器中，添加此项以将其限制为纵向：

-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

UIMoviePlayerControllerDidEnterFullscreenNotification在iOS8中不起作用
