苹果的推送服务

推送功能

当然了上面介绍的这些功能特性只是iPhone OS 4.0众多特性中的冰山一角，但是我们却能够通过这样的一些改变来看到iPhone OS 4.0在整体方面的一个发展趋势，那就是向着更为出众的用户体验、更为强大的功能表现、更为丰富的内容展现方式以及与用户更近的距离这方面去发展。那就让我们一起期待iPhone OS 4.0在六月份的到来吧。

iPhone OS 4.0的主要特性

•Multitasking.

•Spell check (like on the iPad).

•Bluetooth keyboard support (again, on the iPad).

•User-defined wallpaper (a jailbreak favorite).

•Tap to focus when recording video, just like with photos, and a 5x digital zoom for the camera.

•Playlist creation and nested playlists.

•App folders for sorting apps! You can even put an app folder in the dock.

•Enhanced Mail! You can have a merged inbox view, switch between inboxes quickly, and sync to more than one Exchange account. There's also threaded messaging (at last!) and in-app attachment viewing.

•iBooks, just like on iPad, only smaller. You can wirelessly sync books between platforms, a la Kindle.

•Enterprise features, including remote device management and wireless app distribution.

•Game Center. It's like Xbox Live, but for iPhone games. Includes achievements, leaderboards, and match making. It will be available as a "developer preview," and out for consumers later this year
