iOS: Adding a Facebook Like button to a native iPhone app

问题

I would like to know whether it is possible to add a Facebook Like button to a native iPhone app. In the app, the user browses a business directory or deals. When they tap on an item to view the details, it would be nice to have a Facebook Like button that can be used to post the item to the user's Facebook page.

Facebook writes: "Currently, the Like button is only available in mobile web apps".

My app is a native app and not a web app, so therefore I assume it's not possible. However, I do assume that it is possible to mix native UI components on a screen along with web components and therefore it might be possible to implement the Like button, although I am not sure how you pass data from the native portion to the web portion.

If the only solution is a hack, then I won't implement it because at some point the hack will fail when Facebook alters their API.

read around SO a little, you get many leads. Here's one: Like button in iOS application

And a comment points to github.com/brow/FacebookLikeView

It has same caveats, but it seems there aren't any magic solutions.

There are these blogposts as well:

But not sure you get a native UIButton. Maybe you can open a webview in the background and emulate a click on it...

GL, update if you have some findings, Oded.

Now you can use the FBlike button using the following code but it need to download latest sdk and it is the beta version :(

Here is the code:

[FBSettings enableBetaFeature:FBBetaFeaturesLikeButton];
[FBSettings enablePlatformCompatibility:NO];
FBLikeControl *like = [[FBLikeControl alloc] init];
like.objectID = @"http://shareitexampleapp.parseapp.com/photo1/";
like.likeControlHorizontalAlignment=FBLikeControlHorizontalAlignmentRight;
like.likeControlStyle=FBLikeControlStyleBoxCount;
[self.view addSubview like];
