NSUserDefaults only loads correctly half of the time - ios
I am currently creating an app with Swift2 that stores user entered data. Right now I am just using NSUserDefaults even though I will be using an external DB in the future.
With my current implementation, I have 2 Dictionaries stored to NSUserDefaults. "allNouns", "myNouns", and "nounTimes". When I load my app, the data only loads every other time. I have my code to get the data and the log print outs below.
func saveObject(object: AnyObject, objectKey: String) {
let objectData = NSKeyedArchiver.archivedDataWithRootObject(object)
NSUserDefaults.standardUserDefaults().setObject(objectData, forKey: objectKey)
}
func loadObject(objectKey: String) -> AnyObject? {
var object : AnyObject? = nil
if( NSUserDefaults.standardUserDefaults().objectForKey(objectKey) != nil ) {
let objectData = NSUserDefaults.standardUserDefaults().objectForKey(objectKey) as? NSData
if let objectData = objectData {
object = NSKeyedUnarchiver.unarchiveObjectWithData(objectData)!
}
}
return object
}
override func viewDidLoad() {
super.viewDidLoad()
if( NSUserDefaults.standardUserDefaults().objectForKey("allNouns") != nil ) {
allNouns = loadObject("allNouns") as! [Int : Noun]
allNounIdList = Array(allNouns.keys)
}
if( NSUserDefaults.standardUserDefaults().objectForKey("myNouns") != nil ) {
myNouns = loadObject("myNouns") as! [Int : [NSDate]]
myNounIdList = Array(myNouns.keys)
}
}
Here are all the places I save data:
func stashNoun(nounId: Int) {
let myNounTimes = myNouns[nounId]
if( myNounTimes == nil || myNounTimes!.isEmpty ) {
myNouns[nounId] = [ NSDate() ]
myNounIdList.append(nounId)
}
else {
myNouns[nounId]!.append(NSDate())
}
saveObject(myNouns, objectKey: "my")
}
#IBAction func addButtonClicked(sender: AnyObject) {
let newNoun = Noun(name: nameTextField, type: typeTextField, year: yearTextField)
allNouns[newNoun.id] = newNoun
allNounIdList.append(newNoun.id)
saveObject(allNouns, objectKey: "allNouns")
}
Here is a log of when I have data:

When you're done sending the data to NSUserDefaults you must call synchronize from its instance to be sure that your data was persisted. Otherwise your data may not be persisted in a timely fashion (the app may be terminated before this call is made automatically).

Can't access a property in a Struct
I have the struct Subsection, like so:
struct Subsection: Decodable {
let subsectionName: String
let subsectionID: Int
}
That is a type in another class MenuInfo, like so:
struct MenuInfo: Decodable {
let subsections: [Subsection]
let menuItems: [MenuItem]
}
Which finally is used inside another struct RestaurantInfo, like so:
struct RestaurantInfo: Decodable {
let restaurantName: String
let menuInfo: MenuInfo
enum CodingKeys: String, CodingKey {
case restaurantName = "restaurant_name"
case menuInfo
}
}
I created a mock constant:
let restaurantMenuInfo = RestaurantInfo(
restaurantName: "SUBWAY",
menuInfo: MenuInfo(
subsections: [
Subsection(subsectionName: "SANDWICHES", subsectionID: 1),
Subsection(subsectionName: "DRINKS", subsectionID: 2),
Subsection(subsectionName: "DESSERTS", subsectionID: 3)
],
menuItems: [
MenuItem(menuItemName: "Chicken Sandwich", menuItemDescription: "Bread / Chicken Filé / Cheese", menuItemPrice: 9.99, subsection: 1),
MenuItem(menuItemName: "BLT", menuItemDescription: "Bread / Bacon / Lettuce / Tomatoes", menuItemPrice: 12.99, subsection: 1),
MenuItem(menuItemName: "BBQ sandwich", menuItemDescription: "Garlix Bread / BBQ Sauce / Roast Beef", menuItemPrice: 14.99, subsection: 1),
MenuItem(menuItemName: "Veggie Burger", menuItemDescription: "Bread / Soy Meat / Pickles", menuItemPrice: 17.99, subsection: 1),
MenuItem(menuItemName: "Mountain Dew", menuItemDescription: "Lemon / Raspberry / Grape", menuItemPrice: 2.99, subsection: 2),
MenuItem(menuItemName: "Iced Tea", menuItemDescription: "Tea with Lemon", menuItemPrice: 3.99, subsection: 2),
MenuItem(menuItemName: "Cookie", menuItemDescription: "Chocolate Chip Cookie", menuItemPrice: 1.99, subsection: 3),
MenuItem(menuItemName: "Cheese Cake", menuItemDescription: "Cheese cake / Blueberry", menuItemPrice: 5.99, subsection: 3),
MenuItem(menuItemName: "Chips", menuItemDescription: "Potato chips", menuItemPrice: 2.99, subsection: 3)
]
)
)
I am trying to get a stack view to load a .xib final with the subsectionName but I can't access the property subsectionName in the ViewController.
func setUpMenuSubsection() {
for subsection in restaurantMenuInfo.menuInfo.subsections.subsectionName {
if let subsectionView = Bundle.main.loadNibNamed("SubsectionView", owner: nil, options: nil)?.first as? SubsectionView {
subsectionView.setUpSubsection(subsection: subsection)
stackSubsections.addArrangedSubview(subsectionView)
}
}
}
But I get the error:
Value of type '[Subsection]' has no member 'subsectionName' on the second line of my function right on ".subsectionName".
The setup of your types is perfectly fine. However, when we look at the loop you are using:
func setUpMenuSubsection() {
for subsection in restaurantMenuInfo.menuInfo.subsections.subsectionName { // <-- this line
if let subsectionView = Bundle.main.loadNibNamed("SubsectionView", owner: nil, options: nil)?.first as? SubsectionView {
subsectionView.setUpSubsection(subsection: subsection)
stackSubsections.addArrangedSubview(subsectionView)
}
}
}
The error is on the marked line. That is because subsections, which is of type [Subsection], does not have a property subsectionName. If you just want to loop over the subsections (which is probably what you want), you can simply remove .subsectionName, and then to access the name of each subsection, inside the loop you would say subsection.subsectionName like so:
func setUpMenuSubsection() {
for subsection in restaurantMenuInfo.menuInfo.subsections {
print(subsection.subsectionName)
}
}
If, however, you want to loop only over the names, and do not care about the subsections themselves, you can do this:
func setUpMenuSubsection() {
for subsectionName in restaurantMenuInfo.menuInfo.subsections.map(\.subsectionName) {
print(subsectionName)
}
}
Connection of varispeed with RemoteIO in iOS
I am working with audio units to play and change the speed of playback. Since AudioGraph is deprecated.
What I have done, I have successfully played Audio coming from UDP via audio-units and made connections like:
converterUnit -> varispeed -> outConverterUnit -> RemoteIO (Out)
Our format for playing is int16(PCM), but varispeed requires float datatype, So we are using converters for varispeed.
Here is my code:
var ioFormat = CAStreamBasicDescription(

numChannels: 1,
pcmf: .int16,

var varispeedFormat = CAStreamBasicDescription(

numChannels: 1,
pcmf: .float32,
isInterleaved: false
)

The problem is, I don't feel any difference in voice if I use varispeed or not. Can anyone point out the problem in my code?

I have studied these answers and tried to implement them in our situation with no result.
I think scopes and elements might be the problem.

With sort and the shorthand arguments you can order the second element in your 2D array like this:
let sortedAfterCountryNames = prefixCodes.sort{ $0[1] < $1[1] }
print(sortedAfterCountryNames)
// [["AF", "Afghanistan"], ["AL", "Albania"], ["DZ", "Algeria"], ["AS", "American Samoa"], ...
Hope this will help you.
let sortedArray = prefixCodes.sort { (first, second) -> Bool in
return first.last < second.last
}
You should use the sort method to sort your array.
Let's first create an unsorted array:
var arr = [["A", "Hello world"],
["C", "Bye world"],
["B", "idk what to say here"]]
Now let's look at what arguments the sort method needs. Apparently it needs a closure of the following signature:
([String], [String]) -> Bool
The most straightforward (but not so swifty) approach would be to write a function with that signature:
func myFunction (first: [String], second: [String]) -> Bool {
}
In that function, you need to decide whether the algorithm should swap the two arguments. If it should not, return true, otherwise false. I think if you want to sort in alphabetical order, you should just compare the two strings
return first[1] < second[1]
You access the element at index 1 because that is where you store the country names, right?
Then, call sort with the function
arr = arr.sort(myFunction)
However, that is not very swifty. To make this the most swifty, you can do this:
arr.sort {
$0[1] < $1[1]
}
Much better!
You may do the following:
prefixCodes.sort { $0[1] < $1[1] }
But to be safer, I think that you should define a Country struct like this:
struct Country {
let code: String
let name: String
init(_ code: String, _ name: String) {
self.code = code
self.name = name
}
}
let countries = [Country("AD", "Andorra"), Country("AE", "United Arab Emirates"), Country("BQ", "Caribbean Netherlands")]
print(countries.sort { $0.name < $1.name })
So that if you want to add more details to your countries, you will not have a chance to break your sort closure.
Or if you want to keep things simple but still enforce strong typing, you could use tuples:
let countries = [("AD", "Andorra"), ("AE", "United Arab Emirates"), ("BQ", "Caribbean Netherlands")]
print(countries.sort { $0.1 < $1.1 })
If you mix different tuple lengths in your array:
let countries = [("AD", "Andorra"), ("toto"), ("tata", "titi", "tutu")]
Swift will return this error:
error: type of expression is ambiguous without more context
Image from iphone app to wcf service
Can any one suggest me that how can I retrive a image from iphone app through WCF web service
and save it to a directory.
I am recieving a image from iphone app in form of NSDATA(Don't know about that,Actually iphone develpoer is giving me a image as Nsdata).
and I am doing like this to convert this data to image and save to my directory
public Image byteArrayToImage(byte[] byteArrayIn)
{
Image returnImage = null;
string ApplicationVerifyPath = ConfigurationManager.AppSettings["ImagePath"].ToString();
ApplicationVerifyPath = ApplicationVerifyPath + "RetailerAdmin/ProductImages/";
using (MemoryStream ms = new MemoryStream(byteArrayIn, 0, byteArrayIn.Length))
{
ms.Write(byteArrayIn, 0, byteArrayIn.Length);
ms.Seek(0, SeekOrigin.Begin);
returnImage = Image.FromStream(ms);
returnImage.Save(ApplicationVerifyPath + returnImage, System.Drawing.Imaging.ImageFormat.Png);
}
return returnImage;
}
it is showing (parameter is invalid error in Image.FromStream(ms).
Kindly help me to get out from this solution.

You can try the below way as I had implemented in one of my project when intergrating WCF REST service in iPhone.
Get NSDATA to string property or variable. Use this string as Base64 string and convert it into an image and save it to your directory.
public void Base64ToImage(string imageString)
{
// Convert Base64 String to byte[]
byte[] imageBytes = Convert.FromBase64String(imageString);
MemoryStream ms = new MemoryStream(imageBytes, 0,
imageBytes.Length);
// Convert byte[] to Image
ms.Write(imageBytes, 0, imageBytes.Length);
System.Drawing.Image image = System.Drawing.Image.FromStream(ms, true);
image.Save("Base64ToImage.png"); //Specify your filename here
}
