camera-roll

So I'm using Expo's Camera API to take a picture, like so: takePicture = async function() { if(this.camera) { this.camera.takePictureAsync().then(data => { CameraRoll.saveToCameraRoll(data.uri); }).then(() => { this.setState({ photoId: this.state.photoId + 1, }); }); } }; Now, I'd like to specifically retrieve the pictures I take with this app to work with later. I figure an easy way to do this would be if the app saved its pictures to a separate folder in the camera roll, much like how Instagram makes its own folder in there. How would I go about having the app create its own folder in the

One of my app's features is to download a mp4 file and store it to the local phone album. I have tried several approaches since and the result is always the same, it worked on the simulator but not on the actual iPhone. Xcode is version 5.0.1, iPhone 4.

From what I can see, the only way to access all photos in iOS 8 is through the Collection view (in the Photos app or the new built-in

I try to get the last photo from camera roll and delete it.Now I get the last photo but have problems in deleting the last photo. I tried this way but I delete all photos,so I plan to build a new PHFetchResult which only include the last photo but I don't know how to do that. PHPhotoLibrary.sharedPhotoLibrary().performChanges( { PHAssetChangeRequest.deleteAssets(fetchResult)}, completionHandler: { success, error in NSLog("Finished deleting asset. %@", (success ? "Success" : error)) }) Thank all of you to answer my question! I guess the problem lies in your fetchResult . You will have to pass
