如何获取存储在设备中的所有图像，并在iPhone sdk中将它们显示为图库 [英] How to get all the images stored in the device and show them as gallery in iPhone sdk

问题描述

我希望将所有图像存储在设备中，并在我的iPhone应用中将其显示为图库。 UIImagePickerController以缩略图视图显示所有照片，并且在选择每张照片时，我们只获取该特定所选图像的数据，而不想一次性获取所有照片并将其显示为图库。这是可能的，如果是，请告诉我如何做到这一点。 AssetLibrary有什么用？它是否对我需要实现的目标有所帮助。如果是，请告诉我如何使用AssetLibrary实现这一目标。

Is this possible, if yes please tell me how to do this. What is the use of AssetLibrary ?. Does it help what I need to achieve.If yes, please tell me how to achieve this using AssetLibrary.
