我正在做一个涉及ALassets的项目。我知道,从iphoto手机中的每张照片都属于一个事件。事件似乎就像文件夹。我不清楚的是,如果您将手机同步到PC而不是Mac,那么每项资产是否仍属于某项活动?
感谢您的建议。

AssetLibrary有所谓的组。这些组包含资产。有以下类型的组:
enum {
ALAssetsGroupLibrary = (1 << 0), // The Library group that includes all assets.
ALAssetsGroupAlbum = (1 << 1), // All the albums synced from iTunes or created on the device.
ALAssetsGroupEvent = (1 << 2), // All the events synced from iTunes.
ALAssetsGroupFaces = (1 << 3), // All the faces albums synced from iTunes.
ALAssetsGroupSavedPhotos = (1 << 4), // The Saved Photos album.
ALAssetsGroupPhotoStream = (1 << 5), // The PhotoStream album.
ALAssetsGroupAll = 0xFFFFFFFF, // The same as ORing together all the available group types,
// with the exception that ALAssetsGroupLibrary is not included.
};
资产只是事件的一部分,如果它已被iTunes同步或由相机连接套件创建。在设备上拍摄的照片始终是ALAssetsGroupSavedPhotos(相机胶卷)的一部分,还可以分配给用户创建的相册。
