storage

I would like to store and update a Dictionary when a user enters a value. Everything seems to function until this code, and the application crashes: override func viewDidLoad() { super.viewDidLoad() if NSUserDefaults.standardUserDefaults().objectForKey("dict") != nil { answersSaved = NSUserDefaults.standardUserDefaults().objectForKey("dict") as [String:String] } } The error message says "anyObject is not convertible to [String:String]. It offers to add ! after the as but then the app crashes. dict is my Dictionary variable with Strings as values. I also have code updating the NSUserDefaults

When attempting to update a record within indexeddb using the put method, it appears that a new value is created rather than a change. According to MDN this is the method to update a record, yet I'm not having the expected result. Any ideas? Here is my code example. /* @keys initalisation */ extension.onupgradeneeded = function (event) { database = event.target.result; if (!database.objectStoreNames.contains('profile')) { var _profile = database.createObjectStore('profile', { autoIncrement: true }); _profile.createIndex('default', 'default', { unique: true }); _profile.createIndex('username',

My App had been rejected because I save in-app purchase data in Documents folder on iPhone. Data that can be recreated but must persist for proper functioning of your app - or because customers expect it to be available for offline use - should be marked with the "do not back up" attribute. For NSURL objects, add the NSURLIsExcludedFromBackupKey attribute to prevent the corresponding file from being backed up. For CFURLRef objects, use the corresponding kCFURLIsExcludedFromBackupKey attribute. But I want the user to use the data even if they are offline, so I'll use

So I have this text on the java-side that arrives from an Intent , which I'd like to save to AsyncStorage to being able to access it through React afterwards. Any chance I can achieve this? I have: package com.myapp; import android.app.Activity; import android.os.Bundle; import android.view.KeyEvent; import android.content.Intent; import com.facebook.react.LifecycleState; import com.facebook.react.ReactInstanceManager; import com.facebook.react.ReactRootView; import com.facebook.react.modules.core.DefaultHardwareBackBtnHandler; import com.facebook.react.shell.MainReactPackage; import com

I want to be able to use Android's internal storage. I found some code snippets like: string path = Application.Context.FilesDir.Path; var filePath = Path.Combine(path, "test.txt"); System.IO.File.WriteAllText(filePath, "Hello World"); But I could not figure out what Application is in here. Is there any solution for that or different perspective? Thanks :) Use this: string path = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal); string filename = System.IO.Path.Combine(path, "testfile.txt"); // Write using (var streamWriter = new StreamWriter(filename, true)) {
