I subscribe to a number of Google calendars and while those calendars appear on my Mac, they don't show up in my iPhone's Calendar app. How can I configure the iPhone so the events are added automatically?
As you've likely noticed, in OS X's Calendar application you can select Calendar > Preferences > Accounts, select your Gmail account, click on the Delegation tab, and then enable any calendars you're subscribed to. This option doesn't exist in iOS. Thankfully, with the help of your iPhone's copy of Safari, you can add these calendars.
On your iPhone go to https://www.google.com/calendar/syncselect. On the resulting page log into your Gmail account and tap Sign In. In the screen that appears you'll see listings for not only your Gmail calendars, but also those calendars you've subscribed to. Enable those calendars you'd like to sync with your iPhone and it's done. When you next open the Calendar app you'll the events these calendars contain embedded in your calendar.
