Swift从相机胶卷中获取图像和视频

我使用"PHAsset"来获取相机胶卷资产.我在用

PHAsset.fetchAssetsWithMediaType(.Image, options: options)

用于获取所有图库图像.但我想同时获取所有图像和视频并在集合视图中显示(如Instagram相机视图).

请问任何人请告诉我该怎么做？

实际解决方案(swift 4,可能是swift 3):在你的viewDidLoad中,或者适用于你的案例调用checkAuthorizationForPhotoLibraryAndGet()

    private func getPhotosAndVideos(){

        let fetchOptions = PHFetchOptions()
        fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate",ascending: false)]
        fetchOptions.predicate = NSPredicate(format: "mediaType = %d || mediaType = %d", PHAssetMediaType.image.rawValue, PHAssetMediaType.video.rawValue)
        let imagesAndVideos = PHAsset.fetchAssets(with: fetchOptions)
        print(imagesAndVideos.count)
    }

    private func checkAuthorizationForPhotoLibraryAndGet(){
        let status = PHPhotoLibrary.authorizationStatus()

        if (status == PHAuthorizationStatus.authorized) {
            // Access has been granted.
            getPhotosAndVideos()
        }else {
            PHPhotoLibrary.requestAuthorization({ (newStatus) in

                if (newStatus == PHAuthorizationStatus.authorized) {
                        self.getPhotosAndVideos()
                }else {

                }
            })
        }
    }

1)确保使用mediaType =%d而不是mediaType ==%d

2)确保您确实拥有授权并可以访问照片库,否则它将无声地失败.
