Question

我有一个iPhone / iPad应用程序（通用二进制文件），带有常规UIWebView，可在Internet上显示网页。当用户按下Youtube嵌入时，iPhone应用程序正常运行 - 打开视频播放器，当您关闭它时，它会返回到应用程序。但是，在iPad上它崩溃了

（我甚至没有在堆栈跟踪中看到我的应用程序（除了顶级main.m）

在iPad Mobile Safari中，在同一网页上，视频将在网页上就地播放。我有什么需要做的吗？或者我忘了启用某些东西？

据我所知，这个问题只出现在iPhone OS 3.1.3及更低版本下编译的通用二进制文件上。不仅有YouTube视频，还有加载到UIWebView中的各种媒体文件。作为解决方案，您可以覆盖UIWindow并添加一些虚拟方法。

@interface MyWindow : UIWindow {
}
@end

@implementation MyWindow {
- (void)addEventMonitor:(void *)monitor {}
- (void)pendingMouseUpCount {}
}

当Youtube播放器在UIWebView中点击时，iPad应用程序崩溃
