Write the VCard data to a temporary location on disk.

Note that some solutions suggested creating an contact via the AddressBook framework and using that to generate the VCard contents, crazy!.

When searching Google for 'uiactivityviewcontroller share location', the top results (I've not checked all ~150,000) point to a very similar solution: So, without further adu, here's the meat to go with your potatoes. The primary focus for this blog post is going to be sharing locations. However, in this case, simply using NSItemProvider will help a lot. Even though it's smart enough to figure out what you want with simple things (such as text, as shown in the example), it cant infer what you want to send for all items.įor more complex items, items should conform to UIActivityItemSource (something I hope to write another blog post on). This may look like an open invitation to just pop anything in the array, but it's actually far from that. Note that UIActivityViewController's designated initialiser takes in an array of AnyObject. On its own, this isn't particularly useful, but it's a start. This would allow the user to share this text via various built-in applications, such as Messages, Mail, or Notes, via 3rd party apps, such as Dropbox or Facebook, or via AirDrop. This would present a Share Sheet sharing 'A shared piece of text'. PresentViewController ( vc, animated : true, completion : nil )

There's not a whole lot of documentation that helps determine exactly how to use UIActivityViewController and its associated classes, but the simplest way to use it would be: // This code assumes: // - This is inside a subclass of `UIViewController` // - This is inside a class that contains a property called `shareBarButtonItem` of type `UIBarButtonItem` let activityItems : = let vc = UIActivityViewController ( activityItems : activityItems, applicationActivities : nil ) // If run on iPad, this is required vc. UIActivityViewController and UIActivityItem

The full list can be found in Apple's Documentation. In the blog post we'll be looking at location exclusively, but there are a various things that can be shared, from images, to URLs, to text files.

When tapping this, the user is presented with a Share Sheet, which provides various options, depending on the item being shared. Sharing on iOS is done using the Share Sheet, which is often opened via the 'Action' icon (shown left). This is the first post in a series of planned posts going over a few of the tips, tricks, and common pitfalls I have found while working with iOS Share Sheets. Sharing a location on iOS is something that not a lot of apps need, but after requiring it for my latest app, Scanula, I found that there isn't a good resource explaining how to do it properly.
