Load YouTube outside Application

问题

I have a simple UIWebView showing a page including YouTube thumbnail. When I click it, it loads it inside the application, but I want it to be loaded outside application in the YouTube-app. How can this be done?

Thanks.

回答1:

It should be as simple as loading the YouTube-video-url like this:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.youtube.com/watch?v=abcde12345"]];

It won't work in the simulator because it doesn't have the YouTube-app, but it will work on the iPhone (i hope, untested).

(I also see that your accept-rate is pretty low, you should click the little ✔ next to the answer that you think is the best answer. That way people wondering about the same thing can find the most useful answer fast and the person posting the answer will be accredited.)

EDIT: Here is an example of what you could do to catch the YouTube-urls and opening them in the YouTube-app instead of in your app:

- (BOOL)webView:(UIWebView *)wv shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

    // Determine if we want the system to handle it.
    NSURL *url = request.URL;
    if ([url.host isEqual:@"youtube.com"] && ([url.query rangeOfString:@"watch"] != 0)) {
        if ([[UIApplication sharedApplication]canOpenURL:url]) {
            [[UIApplication sharedApplication]openURL:url];
            return NO;
        }
    }
    return YES;
}

This is not tested, but should work :)

Method 2: Embed the YouTube player in a UIWebView

No, the iPhone still doesn't do Flash, but if you haven't already noticed, the Safari browser on the iPhone is clever enough to turn any YouTube embed into a clickable thumbnail that launches the native YouTube player app on the phone. You can take advantage of this feature in your app by using a UIWebView. Here's how:

Set up a UIWebView in your app. You can make it part of a xib or create it programmatically. Size the UIWebView according to how large you want the clickable thumbnail to be.

Grab the video url using the same method as the one described above.

Call the loadHTMLString:baseURL: method on the UIWebView instance with some carefully constructed HTML that contains the YouTube embedded player code snippet and some supporting HTML to make sure that the video thumbnail appears correctly. Set the base URL to the URL of your website (it doesn't do anything here -- ordinarily UIWebView uses it to handle relative URL links correctly).

The best way to illustrate this is with a code snippet. Note the use of the viewport HTML meta parameter and the consistent use of width and height parameters throughout.

// webView is a UIWebView, either initialized programmatically or loaded as part of a xib.

NSString *htmlString = @" ";

[webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:@"http://www.your-url.com"]];

One of the biggest benefits of this approach is that your app does not have to quit in order for the video to start playing. In fact, the iPhone will keep your app running in the background while it fires up the YouTube player to play the video. After the video finishes playing (or when the user hits "Done"), the user is automatically taken back to your app. This experience is very similar to watching embedded YouTube videos in the iPhone Safari browser and is just as seamless.
