问题 Following @matt's code when using the UIImagePicker , I can prevent the user from picking a .livePhoto once an image is choosen using: let asset = info[UIImagePickerControllerPHAsset] as? PHAsset if asset?.playbackStyle == .livePhoto { // alert user this photo isn't a possibility } When using the PHFetchOptions how can I prevent them from being shown instead of filtering them out inside the enumerateObjects callback? fileprivate func fetchPhotos() { let fetchOptions = PHFetchOptions()

问题 iOS 13 beta4 no longer gives 1) PHImageFileURLKey 2) PHImageResultIsDegradedKey in image result info keys. Anyone knows a way to find the fileurl of the PHAsset? 回答1: You have to use this function from PHAsset object: - (PHContentEditingInputRequestID)requestContentEditingInputWithOptions:(nullable PHContentEditingInputRequestOptions *)options completionHandler:(void (^)(PHContentEditingInput *__nullable contentEditingInput, NSDictionary *info))completionHandler; Then you can retrieve URL

问题 How can I get the path or directory of the PHAsset images? I came across an answer here written by @diegomen but when I try it like selectedAssets[0].PHAsset.getURL() it asks for a parameter but @diegomen said it doesn't require a parameter from the comments. Am I applying it wrong? Or is there other way of getting the images path from PHAsset ? NOTE: I found another solution here by @Clay but it doesn't seem to be the good practice to do it. 回答1: If you have already store image in your local

问题 I am enumerating a PHFetchResult. If I do a println on the PHAssets being returned, I get this: <PHAsset: 0x178192140> 4CBE5A4F-90BD-438B-954E-6FF1B14538CD/L0/001 mediaType=1/0, assetSource=3, (2448x3264), creationDate=2014-10-15 14:20:12 +0000, location=1, hidden=0, favorite=1 Does anyone know what the assetSource=3 bit is? I would like to run a predicate on the assetSource if possible but can't find any information anywhere on what it is or how to access it. Is it private? 回答1: assetSource

问题 I have a custom album in which my app saves picture from camera. I am wondering if there is a way I can create folders inside my album so I can stack certain images inside it? ANSWER As fellow members mentioned, sadly there is no way you can create a folder inside album. 回答1: You should try code below. It's Swift 3.0 syntaxe. :) import Foundation import Photos class CustomPhotoAlbum: NSObject { static let albumName = "Album Name" static let sharedInstance = CustomPhotoAlbum() var

问题 I'm performing a request to get an image asset given a PHAsset , and I'm using UIProgressView to indicate the progress using the progressHandler PHImageRequestOptions allows me to provide. When that handler is called, it provides me with progress so I set the progress on the progress view but I also animate to that new progress via setProgress:animated: . I now need to figure out how to hide the progress view once progress has reached 1.0, but not until it has finished animating to 1.0. For

问题 I have converted some PHAsset to UIImage : PHImageManager *manager = [PHImageManager defaultManager]; [manager requestImageForAsset:asset targetSize:PHImageManagerMaximumSize contentMode:PHImageContentModeDefault options:requestOptions resultHandler:^void(UIImage *image, NSDictionary *info) { convertedImage = image; [images addObject:convertedImage]; }]; Now I want to do something like that: [selectedAssets removeObject:image]; where selectedAssets is an array of PHAsset and image is an

问题 I want to parse all images from my MacOS Photos Library, using PHAsset. However all examples I find are only working for iOS, like the one below, where the last line, which retrieves the assets is not available on macos framework: NSMutableArray *photos = [[NSMutableArray alloc] init]; PHFetchOptions *allPhotosOptions = [[PHFetchOptions alloc] init]; allPhotosOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]]; // Below compilation error as

问题 I have a photo I want my user to be able to share on Instagram and I need to get the local file directory of the photo. However I am fetching my images as a PHAsset (not the ALAsset all the other answers seem to cover on this subject). Looking at the PHAsset documentation I don't see a 'local directory' variable. Do you know how I can get the path to a photo from the users camera roll using the new ios8 Photo's framework? Here is my code for loading the last image in the users photo roll

问题 I am trying to share video PHAsset via UIActivityController using requestAVAsset. This works with Messaging, but not with AirDrop, indicating as 'Failed'. PHCachingImageManager.default().requestAVAsset(forVideo: asset, options: nil, resultHandler: { (givenAsset, audioMix, info) in let videoAsset = givenAsset as! AVURLAsset let videoURL = videoAsset.url DispatchQueue.main.async { let activityViewController = UIActivityViewController( activityItems: [videoURL], applicationActivities: nil)
