How to open the Pinterest App from your own iOS App

Pinterest_Badge_RedYou can open Pinterest links from your iOS app directly in the Pinterest app if it’s installed. This includes direct links to a user, a user’s board, or a specific pin.

In the following code snippets we’ll do just that, and if the Pinterest App is not installed on the device we’ll open the link in Safari instead. These methods can be hooked up to a UIButton.

Note that for this to work, users need to be logged in to the Pinterest App – otherwise the app opens with a login prompt and not the link we want.

Opening a Pinterest User Profile

Much like on Twitter, users on Pinterest have handles. Mine is versluis2000, and my Pinterest URL is http://www.pinterest.com/versluis2000. Here’s how you open this user via the Pinterest app:

Trying to display your own Pinterest User Profile may crash the Pinterest App – at least that’s what happened in my tests.

Opening a Pinterest Board

Users on Pinterest can pin links to their boards which work like collections or categories. Those boards have slugs that appear after the user handle. I have a board called iOS Projects which has the following URL: http://www.pinterest.com/versluis2000/ios-projects/

Here’s how we can open one directly in the Pinterest App:

Opening a Pinterest Pin

When a user finds a link on the web and pins it, the link will receive a unique numeric ID. Such an ID is independent from the user who pins it. Here’s a pin to a sketch of a Polaroid camera I drew: http://www.pinterest.com/pin/76279787413881109/

Let’s open this pin in the Pinterest App:

How about pinning something directly from my own app?

If you’d like users to pin something directly from your app, take a look at the iOS Pin It SDK – brought to you by the friendly folks at Pinterest. The article also explains the deep linking structure we’re using in the above examples:

How to open the Google Plus App from your own iOS App

Google+To open a URL inside the Google+ App we need to know the Google+ URI scheme.

Instead of http:// it’s gplus:// – so if your Google+ URL in a web browser is http://plus.google.com/+WpguruTv, then you can open the same URL from your iOS App with gplus://plus.google.com/+WpguruTv

Let’s have a look at how to do this in code:

First we try to open the Google+ App using the gplus:// URI. If that’s unsuccessful we’ll open the standard http:// URI which will automatically bring up Safari.

It’s a good idea to test for network connectivity before attempting to open any URL (for example with the excellent Reachability by Tony Million).

Links to the latest Social Icons

InBug-60px-RFacebook, Twitter & Co. change their brandings every now and again, and every time I need them for a project I keep scrambling to find the official links. Well no more – here’s a list of them all:

How to open the LinkedIn App from your own iOS App

Here’s a sample action that tries to open a LinkedIn Profile with the LinkedIn App. If it’s not installed, it opens a link to the profile in Safari. If that doesn’t work it gives a log message (please handle appropriately in your own code):

Note that currently you can only link to personal profiles, not to company profiles.

To create a dynamic web button with follower count (or not), check out the LinkedIn Developer Portal and load the code into a small UIWebView.

At the time of writing it appears that none of the LinkedIn provided plugins are actually working anywhere other than the preview. Looks like we’ll have to use a standard graphic instead until this is fixed.

How to open the Twitter App from your own iOS App

Opening the Twitter App is pretty much the same as opening the Facebook App discussed earlier, just the URL scheme is different.

This is how we open Twitter so people can follow the user (me in this case, versluis). If the call is unsuccessful, we’ll try to open the Twitter page in Safari. And if that doesn’t work, we’ll display a log message:

To find out which other apps you can opened, and to figure out what scheme they follow:
