调用系统录制并成功保存到相册--Swift

效果图：

这次直接上效果图，不然大家也不知道具体乱糟糟的代码是什么鬼。

首先项目需要这两个： AVFoundationimport 和 MobileCoreServices

1、先实例化一个按钮，这个就不用贴代码了吧。
2、然后初始化摄像机以及设置参数：

func initImagePicker(){

    imagePicker = UIImagePickerController()
    //设置imagePicker的来源，这里设置为摄像头
    imagePicker.sourceType = .Camera
    //设置为后摄像头
    imagePicker.cameraDevice = .Rear
    //设置摄像头的类型(录像)
    imagePicker.mediaTypes = [String(kUTTypeMovie)]
    //设置摄像头捕获模式
    imagePicker.cameraCaptureMode = .Video
    //是否允许编辑
    imagePicker.allowsEditing = true
    //设置摄像头的质量(高清)
    imagePicker.videoQuality = .TypeIFrame1280x720
    //设置代理检测操作
    imagePicker.delegate = self
}

3、完成代理和设置保存路径：

extension ViewController: UINavigationControllerDelegate, UIImagePickerControllerDelegate {
//完成回调
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let url = info[UIImagePickerControllerMediaURL] as! NSURL
let urlStr = url.path
if UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(urlStr!) {
//保存视频到相簿，注意也可以使用ALAssetsLibrary来保存
UISaveVideoAtPathToSavedPhotosAlbum(urlStr!, self, "video:didFinishSavingWithError:contextInfo:", nil)
print("保存成功......")
}
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Phone) {
self.dismissViewControllerAnimated(true, completion: nil)
}
}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    print("取消录制")
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Phone) {
        self.dismissViewControllerAnimated(true, completion: nil)
    }
}

}

func video(videoPath: String, didFinishSavingWithError error: NSError, contextInfo info: AnyObject) {
print("保存成功")
let url = NSURL(fileURLWithPath: videoPath)
player = AVPlayer(URL: url)
let playerLayer = AVPlayerLayer(layer: player)
playerLayer.frame = imageView.bounds
imageView.layer.addSublayer(playerLayer)
player.play()
}

最近在学习多媒体后续还会写一些例子，大家多多指点。

自学笔记、谨慎阅读。
