iOS 8 will bring third-party keyboards, Notification Center widgets, Safari extensions

In a demonstration at Monday's Worldwide Developers Conference keynote, Apple software chief Craig Federighi showed off Notification Center on both iPhone and iPad. One widget showed current sports scores via ESPN SportsCenter, and another one allowed users to track and update bids on eBay through the auction site's app.

In another example, Federighi accessed a Bing translation extension included in the Safari browser on iPad. This allowed him to quickly translate a page to English using Microsoft's search engine.

Another extension for Pinterest was shown, allowing Federighi to quickly post items he found to his Pinterest account. The extension automatically pulled pictures from the website and allowed him to select the one he wanted.

Finally, Federighi revealed to great applause that iOS will now support third-party keyboards. Users will be able to install their own keyboards of their choosing.

Apple will also introduce its own enhanced keyboard, dubbed "QuickType," in iOS 8, which will predict what a user may want to type based on their past usage.
