phasset

问题 I want to upload PHAsset but I do not have the file path of the asset. I am able to upload the file using the below block methods. But these are asynchronous methods to get the URLs. Is there any synchronous method to do so or any other way to upload the PHAsset files. Image Asset URL: [asset requestContentEditingInputWithOptions:editOptions completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) { NSURL *imageURL = contentEditingInput.fullSizeImageURL; }]; Video

问题 Is there a way to get the file size on disk of a PHAsset without doing requestImageDataForAsset or converting it to ALAsset ? I am loading in previews of a user's photo library - potentially many thousands of them - and it's imperative to my app that they know the size before import. 回答1: You can grab the fileSize of a PHAsset and convert it to human readable form like this: let resources = PHAssetResource.assetResources(for: yourAsset) // your PHAsset var sizeOnDisk: Int64? = 0 if let

问题 I am asking the same question as here I do not understand how to implement to solution. I have tried the following fileprivate func fetchPhotos(indexSet: IndexSet) { let allPhotos = PHAsset.fetchAssets(with: .image, options: assetsFetchOptions()) DispatchQueue.global(qos: .background).async { allPhotos.enumerateObjects(at: indexSet, options: NSEnumerationOptions.concurrent, using: { (asset, count, stop) in let imageManager = PHImageManager.default() let targetSize = CGSize(width: 200, height:

问题 I am actually creating an iOS app, and want to store some details about Photo Library pictures in an SQLite database. I also would like to be able to share this data across the different devices the user has (imagine someone wanted to reorganize pictures on his iPhone, and wants to retrieve the same order in his iPad). I have searched across the Apple documentation, but did not find any PHAsset identifier that is shared across devices. I also tried to check if the PHImageFileURLKey ,

问题 Xcode says that PHAsset doesn't have the 'location' member. What's the remedy for Swift? 回答1: Short answer: you might have forgotten to import CoreLocation; import Photos import CoreLocation let asset: AnyObject? = nil if let asset = asset as?

问题 I want to play video from PHAsset , collected from iOS Photos. PHAsset video nsurl (https://stackoverflow.com/a/35099857/1084174) is valid to my own application lets say MyPlayer for few moments/blocks. When I am copying the image/video into MyPlayers own sandbox only then the nsurl becomes always valid. It seems to me, I need to copy each video from temporary PHAsset nsurl to MyPlayers sandbox (appgroup/documents) and only then I can play the video with sandbox relative nsurl. If this is the
