我想在我的UIWebView控件中播放dailymotion和youtube视频。而且我正在使用以下嵌入式HTML代码来播放它并且工作正常。但是当设备正在旋转时，它没有相应地重置，如果我再次调用以下代码，它将从头开始播放视频。
NSString* embedHTML = @"<html><head><style>body {\"background-color:transparent;color:black;\"}</style></head><body style=\"margin:0\"><embed id=\"yt\" src=\"%@\"type=\"application/x-shockwave-flash\"width=\"%.0f\" height=\"%.0f\"></embed></body></html>";
NSString* html = [NSString stringWithFormat:embedHTML, url, frame.size.width, frame.size.height];
根据设备轮换重置我的视图的任何解决方案并继续播放而不重新启动..？
修改 视频在播放模式下完美改变方向。一旦我停止并尝试旋转视图，webview的内容就不会旋转。我正在寻找解决方案。

我已经为此制作了一个教程，并且它也在使用界面orienatation更改。
这是实施文件。只需将粘贴复制到控制器中，放入您的URL并尝试此代码
#import "TestVideoViewController.h"
#import "UICommonUtils.h"
@implementation TestVideoViewController
@synthesize TestVideoView;
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
//sleep(10.0);
[busyLoadingView hide:YES];
//bShow = NO;
}

//sleep(10.0);
[busyLoadingView hide:YES];
//bShow = NO;
}

这是ViewController的头文件

@end
希望这会对你有所帮助。
如果您需要更多帮助，请告诉我。
修改： 这个代码很可能在模拟器上无法正常工作，因为模拟器没有一个shockwave-flash播放器
