问题 I'm trying to grab a thumbnail of the last photo taken on a device using the new Photos framework in iOS 8. The code I have right now to do this is the following: PHFetchOptions *fetchOptions = [PHFetchOptions new]; fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]]; PHFetchResult *assetsInfo = [PHAsset fetchAssetsWithOptions:fetchOptions]; PHImageRequestOptions *requestOptions = [PHImageRequestOptions new]; requestOptions.version =

问题 I load photos from PHAssets. I get this error log when I load some images and pass them to another view controller. I can't seem to find anything online about this. Anyone encounter this and know what it is? I also get this error along with it: ***** Error: logging directory does not exist /var/mobile/Library/Logs/CrashReporter/DiagnosticLogs/ 回答1: There may be following reason : 1.)

问题 Context I am try to fetch images within range of two dates from the photo library. Firstly, I am getting info of the photo library images one by one in the dictionary form and picking every image date by using key and comparing that date with two dates by using if condition. If that image's date lies between the two dates, I insert that image into array. I am Saving images in array because I would like to show them in a collection view.

What I want to achieve I want something like the image selection in whatsapp (iOS) (see screenshot). When you open the camera, there is also a horizontal slider where you can see all images from your gallery. What I tried Right now I have the following code in my appDelegate: let options = PHFetchOptions() options

问题 I am making an app that takes pictures with AVFoundation and I want to save them to a custom album that I can then query and show in my app. (I'd prefer to not have them in the general photo roll, unless the user wants that) I can't really find anything showing how to do this in Swift... or at all. Is there a different way I am supposed to do this? I found this example on SO but it doesn't make sense to me and I can't get it to work. func savePhoto() { var albumFound : Bool = false var

问题 I am trying to get all the photos from cameraRoll using Photos framework but its taking a lot of time to fetch all the photos from cameraRoll. Is their anyway to add pagination to it ? so i can fetch while scrolling. var images = [UIImage]() var assets = [PHAsset]() fileprivate func assetsFetchOptions() -> PHFetchOptions { let fetchOptions = PHFetchOptions() //fetchOptions.fetchLimit = 40 //uncomment to limit photo let sortDescriptor = NSSortDescriptor(key: "creationDate", ascending: false)

问题 I need to retrieve the names of all the PHAsset existing in the Camera Roll, individually and in a short time. To get the file name, I use the documented originalFilename property of PHAssetResource associated to the PHAsset . This works fine for the first assets, but at some point (after around 400 assets), it starts failing and returning nil every time. Here is a code that shows this behavior (running on an iPhone 7 with ~800 photos in the Camera Roll): PHFetchResult *result =
