b）还有 String 的 pathExtension 和 lastPathComponent 都没了，都改到了 NSURL 下面去了，网上很多资料都还是从 NSString 或者 String 取这些属性
c）AVURLAsset 可以取到视频的时长 CMTimeGetSeconds(AVURLAsset(URL: file.url, options: nil).duration)
三、播放视频
func play(file: File) {
let player = AVPlayer(URL: file.url)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
self.presentViewController(playerViewController, animated: true) {
playerViewController.player?.play()
}
}
四、用 ... 打开
func openIn(file: File, indexPath: NSIndexPath) {
let document = UIDocumentInteractionController(URL: file.url)
let rect = self.tableView.rectForRowAtIndexPath(indexPath)
document.presentOpenInMenuFromRect(rect, inView: self.tableView, animated: true)
}
五、删除视频
func delete(file: File, indexPath: NSIndexPath) {
do {
try fileManager.removeItemAtPath(file.path)
videos.removeAtIndex(indexPath.row)
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)
} catch {
}
}
六、保存到相册
func saveToCameraRoll(file: File, indexPath: NSIndexPath) {
if UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(file.path) {
UISaveVideoAtPathToSavedPhotosAlbum(file.path, self, "image:didFinishSavingWithError:contextInfo:", nil)
} else {
// save faild
}
}
func image(image: UIImage, didFinishSavingWithError error: NSErrorPointer, contextInfo:UnsafePointer<Void>) {
if error == nil {
// save success
} else {
// save faild
}
}
代码说明：
注意 UISaveVideoAtPathToSavedPhotosAlbum 的用法，后面 Selector 写得不对就会报错。
