使用网络应用程序和phonegap播放视频时遇到问题。我的网络应用程序中有一个链接直接链接到mp4文件。我在phonegap的AppDelegate类中为这种类型的URL添加了一个处理程序。
- (BOOL)webView:(UIWebView *)theWebView shouldStartLoadWithRequest:
(NSURLRequest *)request navigationType:
(UIWebViewNavigationType)navigationType
{
NSURL *url = [request URL];
NSLog(@"redirect detected");
if ([[[url path] pathExtension] isEqualToString:@"mp4" ] || [[[url path] pathExtension] isEqualToString:@"m4v" ] || [[[url path] pathExtension] isEqualToString:@"m3u8" ]) {
//video files are .mp4 or m4v, stream indexes are m3u8
//it's a movie, go play!
NSLog(@"Movie detected - playing");
NSLog([url path]);
[self playMovieAtURL:url];
return NO;
} else {
return [ super webView:theWebView shouldStartLoadWithRequest:request
navigationType:navigationType ];
}
}
这很好用,并且调用了电影播放的方法。该方法实现如下(1):
-(void) playMovieAtURL: (NSURL*) theURL {
NSLog(@"PlayMovieAtUrl");
MPMoviePlayerController* theMovie =
[[MPMoviePlayerController alloc] initWithContentURL: theURL];
[self presentMoviePlayerViewControllerAnimated:theMovie];
}
也试过这个(2):
-(void) playMovieAtURL: (NSURL*) theURL {
NSLog(@"PlayMovieAtUrl");
MPMoviePlayerController* theMovie =
[[MPMoviePlayerController alloc] initWithContentURL: theURL];
[theMovie setControlStyle:MPMovieControlStyleFullscreen];
[theMovie setFullscreen:YES];
// Register for the playback finished notification
[[NSNotificationCenter defaultCenter]
addObserver: self
selector: @selector(myMovieFinishedCallback:)
name: MPMoviePlayerPlaybackDidFinishNotification
object: theMovie];
NSLog(@"About to play");
// Movie playback is asynchronous, so this method returns immediately.
[theMovie play];
}
但在这两种情况下都是玩家创造并播放。唯一的问题是,它是隐藏的。可以听到声音,但没有图片。仍然显示webView。 (1)应该在没有任何基于其他地方的帖子的设置的情况下工作。问题(我猜)是,它在AppDelegate类中调用而不是在Controller类中调用。但是我不知道如何使用phonegap实现这个:(任何想法?
答案 0 :(得分:0)
我设法解决了这个问题。问题是,我无法访问WebView的ViewController。但我发现https://gist.github.com/527494作者使用带有phonegap的模态窗口。当我有ViewController时 - 很简单:)
MPMoviePlayerViewController* theMovie =
[[MPMoviePlayerViewController alloc] initWithContentURL: theURL];
[super.viewController presentMoviePlayerViewControllerAnimated:theMovie];
我希望能有所帮助。我花了一整天时间来解决它;)
