我想在我的 UIWebView 控件中播放 dailymotion 和 youtube 视频。我正在使用以下嵌入式 html 代码来播放并且运行良好。但是当设备正在旋转时，它不会相应地重置，如果我再次调用以下代码，它将开始从头开始播放视频。
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];
是否有任何解决方案可以根据设备旋转重置我的 View 并继续播放而无需重新启动......？
编辑: 视频在播放模式下完美地改变了方向。一旦我停止它并尝试旋转 View ，webview 的内容就不会旋转。我正在寻找解决方案。
最佳答案
我已经为此制作了一个教程，其中还涉及界面方向的更改。
这是实现文件。只需将粘贴复制到您的 Controller 中，输入您的 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;
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
//sleep(10.0);
[busyLoadingView hide:YES];
//bShow = NO;
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
//bShow = YES;
//[busyLoadingView showWhileExecuting:@selector(showCursor:) onTarget:self withObject:nil animated:YES];
//[busyLoadingView show:YES];
return YES;
}
- (void)webViewDidStartLoad:(UIWebView *)webView
{
[busyLoadingView show:YES];
}
-(void)viewWillDisappear:(BOOL)animated
{
[self embedVideo1:@"PASS HERE URL1" andVideo2:@"PASS HERE URL2" frame:self.view.frame];
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
CGRect rectFrame = [UIScreen mainScreen].applicationFrame;
self.view.frame = rectFrame;
self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.view.autoresizesSubviews = YES;
//TestVideoView.scalesPageToFit = YES;
//TestVideoView.backgroundColor = [UIColor clearColor];
busyLoadingView = [[MBProgressHUD alloc] initWithView:self.view];
// Add HUD to screen
[self.view addSubview:busyLoadingView];
busyLoadingView.labelText = @"Loading...";
[self embedVideo1:@"PASS HERE URL1" andVideo2:@"PASS HERE URL2" frame:self.view.frame];
//self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
//self.view.autoresizesSubviews = YES;
}
- (void)embedVideo1:(NSString*)url1 andVideo2:(NSString*)url2 frame:(CGRect)frame {
float videoWidth = 748.0;
float videoHeight = 341.0;
//int marginLeft = 10;
//int marginTop = 10;
if ([UICommonUtils isiPad]){
videoWidth = 748.0;
videoHeight = 341.0;
//marginLeft = (int)(frame.size.width - videoWidth) /2;
//marginTop = 10;
} else {
videoWidth = 300.0;
videoHeight = 160.0;
//marginLeft = 10;
//marginTop = 10;
}
NSString* embedHTML = @" \

}
- (void)dealloc {
[super dealloc];
}
@end
这是ViewController的头文件
#import <UIKit/UIKit.h>
#import "MBProgressHUD.h"
@interface TestVideoViewController : UIViewController<UIWebViewDelegate>{
UIWebView *TestVideoView;
MBProgressHUD *busyLoadingView;
BOOL bShow;
}
@property (nonatomic, retain) IBOutlet UIWebView *TestVideoView;
- (void)embedVideo1:(NSString*)url1 andVideo2:(NSString*)url2 frame:(CGRect)frame;
@end

如果您需要更多帮助，请告诉我。
编辑: 此代码很可能无法在模拟器上正常运行，因为模拟器没有 Shockwave-Flash 播放器
