链接以在Android或iOS上启动Facebook或Google+应用

Question

There are very similar questions on the board but I still didn't find satisfying results for my topic.

I have to implement links on our website to redirect to Facebook and Google+ for check-ins to my company. It should be possible to click on the link on the website and my smartphone (Android) should ask if this link should open for example the Facebook App or the Link to the Site in the Smartphone browser.

Is there a link that the smartphone can parse: -the app is installed, would you like to open the G+ or Facebook app -or open the web-browser from the smartphone

The link should also redirect me on the Facebook/G+ site of my company. So after the user chooses the app or web browser he/she should be able to check-in with one click.

I think there are already standards for links like this. I just can't find any satisfying results for my problem.

I am currently testing with Android but it would be cool if the links would be also working with iOS :-)

This would be a similar question.

I added this html snippet to my page: href="fb://page/77664937087"

The problem is I have to parse if the user has installed the app or the browser. In this case the app would open. But I need some sort of if-statement. I am no javascript pro so I need some help for this.

And I don't want to implement 2 seperate links for app or browser.

You can use this method of UIApplication to check whether the app is installed:

- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);

If can not you can open the url using following code:

NSString *url = @"xxxxxx"; //your link here
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
