On iOS you simply tap the arrow that is presented when you are looking at a detailed view of the content or app. As you can see from the image below, a series of options will be presented. Selecting any of these will launch their specific app. Tapping on Copy Link will of course allow you to paste the link, to the content, into any text based document on your device.
Within iTunes on the Mac, you have a few similar options to explore. By clicking the down arrow button, next to the price of the content, you can select to Tell a Friend, Copy Link, and Share on Facebook or Twitter.
When you select Tell a Friend, you will be presented with an additional window that allows you to enter the email address of the recipient, along with a message to accompany the link.
Whilst this is a basic and clean process you may prefer selecting the option to Copy Link. You can then paste the link into a new email in your preferred Mail application.
Interestingly, when you look at sharing the link for an application from within the Mac App Store, you have the option of Share in Messages as well. This process is the same as the version found in the iOS App Store. Unfortunately, this functionality is not yet available for iTunes on either the Mac or iOS.
So there you have it. Plenty of ways to share the content you consider to be valuable with others. At mac-fusion, we are always interested in finding wonderful new apps and content.
