nsuserdefaults

when my app starts music is playing: -(void)playBgMusic { NSString *path = [[NSBundle mainBundle] pathForResource:@"bgmusic" ofType:@"aif"]; theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; } but he should be able to turn the music off by pressing a button if he presses the button again the music should turn on again. i have: -(IBAction)check { if (isquiet == NO) { [theAudio stop]; isquiet = YES; defaults = [NSUserDefaults standardUserDefaults]; [defaults setBool:YES forKey:@"stringKey"]; } else { [self

I have a custom class called Person that stores various attributes about someone when they enter information. class Person { // Person dictionary variable var name: String? var age: String? var html_url: String? init(json: NSDictionary) { // Dictionary object self.name = json["name"] as? String self.age = json["age"] as? String self.html_url = json["html_url"] as? String // Location of the JSON file } } Once the dictionary is created, it is then placed into an array. I am having problems saving the array into NSUserDefaults when a button is tapped. personArray.append(newPerson) // newPerson =

I have recently been building an app using [NSUserDefaults standartdUserDefaults] to store locally various information (regarding the session, user preferences, etc). Now I am exporting a subpart of my project as an iOS framework (the goal is to make a SDK). I am generating a MyKit.framework and MyKit.bundle to be imported in third party apps (the bundle contains Storyboards, Localizable.strings and .xcassets). For the moment, I made sure that resources used by MyKit.framework are loaded from the MyKit.bundle scope and not the [NSBundle mainBundle] to avoid collisions with resources from the

There seems to be a strange issue with iOS Playgrounds where NSUserDefaults always returns nil instead of the actual value. In an iOS Playground the last line wrongly returns nil . import UIKit let defaults = NSUserDefaults.standardUserDefaults() defaults.setObject("This is a test", forKey: "name") let readString = defaults.objectForKey("name") In an OSX Playground the last line correctly returns "This is a test". import Cocoa let defaults = NSUserDefaults.standardUserDefaults() defaults.setObject("This is a test", forKey: "name") let readString = defaults.objectForKey("name") Any idea why

So I've been looking around and following all the steps to setup shared UserDefaults correctly but I should be missing something. I have App Groups capability activated on both my app and my extension. Both use the same suite name ( "group.TestSharedPreferences" ) and I write this way: struct Preferences { static let shared = UserDefaults(suiteName: "group.TestSharedPreferences")! } On viewDidLoad : Preferences.shared.set(1, forKey: "INT") And to read: Preferences.shared.integer(forKey: "INT") // Returns 1 in Container App Preferences.shared.integer(forKey: "INT") // Returns 0 in Today

In reference to the following question: iPhone: How do I detect when an app is launched for the first time? When I looked up NSUserDefaults apple reference, it said that registerDefaults does not store the data onto the disk. In the above question, the app registers the value firstLaunch to YES upon each launch. So each time the app is launched, firstLaunch is overwritten to YES and so the app will always think that this is the app's initial launch. Am I right on this? EDIT: After doing what the tutorial above says, it doesn't always work anyway. I keep relaunching from Xcode and it keep

So I've been trying for a few hours for a way to store an array to NSUserDefault and print them to the cells but the data is not saving as an array, it basically only saves one value at a time. var emailData = [String]() var passwordData = [String]() @IBAction func addPressed(sender: AnyObject) { let defaults = NSUserDefaults.standardUserDefaults() emailData.append(addEmail.text!) passwordData.append(addPassword.text!) var storedEmail = defaults.objectForKey("emailData") as? [String] ?? [String]() var storedPasswords = defaults.objectForKey("passwordData") as? [String] ?? [String]() // then
