下面显示的代码就是我已经尝试过的。我希望实现的是从设备中获取所有照片。目前只有少数被提取。如何修改代码以加载所有图像从设备?
let fetchOptions = PHFetchOptions()
let collection:PHFetchResult = PHAssetCollection.fetchAssetCollectionsWithType(.Moment, subtype: .Any, options: fetchOptions)
if let first_Obj:AnyObject = collection.firstObject
{
self.assetCollection = first_Obj as! PHAssetCollection
}

更新了David对iOS 10+&的回答 Swift 4.x / 3.x :
请求设备访问照片的权限:
将以下值添加到info.plist
隐私 - 照片库使用说明
并提供向用户显示的字符串。
请求所有图片:
PHPhotoLibrary.requestAuthorization { status in
switch status {
case .authorized:
let fetchOptions = PHFetchOptions()
let allPhotos = PHAsset.fetchAssets(with: .image, options: fetchOptions)
print("Found \(allPhotos.count) assets")
case .denied, .restricted:
print("Not allowed")
case .notDetermined:
// Should not see this when requesting
print("Not determined yet")
}
}

所有照片都非常简单,但您需要确保首先获得授权。这是一些简单的代码来演示:
PHPhotoLibrary.requestAuthorization { (status) in
switch status
{
case .Authorized:
print("Good to proceed")
let fetchOptions = PHFetchOptions()
let allPhotos = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions)
print("Found \(allPhotos.count) images")
case .Denied, .Restricted:
print("Not allowed")
case .NotDetermined:
print("Not determined yet")
}
}
在我的手机上,这会返回25750项。在新的模拟器上,这应该产生5张图像。
