我正在做一個涉及ALassets的項目。我知道,從iphoto的每個圖片都屬於一個事件。事件似乎像文件夾。我不清楚的是,如果您將手機同步到PC而不是Mac,那麼每項資產是否仍然屬於某個事件?ALAsset每個資產是否屬於一個事件?

感謝您的建議。

AssetLibrary具有所謂的組。這些組包含資產。有以下類型的組:

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. 
}; 

資產只是事件的一部分,如果它已通過iTunes同步或由Camera Connection Kit創建。在設備上拍攝的照片始終是ALAssetsGroupSavedPhotos(相機膠捲)的一部分,並且可以另外分配給用戶創建的相冊。
