Hello with the new beta 2 i got a new problem that i couldn't solve.
var message = MSMessage()
var template = MSMessageTemplateLayout()
viewDidLoad() {
if let filePath2 =
Bundle.main().pathForResource("synth", ofType: "wav") {
let fileUrl = NSURL(string: filePath2)
let URL2 = fileUrl as! URL
template.mediaFileURL = URL2
}
message.layout = template
guard let conversation = activeConversation else {
fatalError("Expected a conversation") } conversation.insert(message,
localizedChangeDescription: nil) { error in
if let error = error {
print(error)
}
}
}
anyone else have the same problem? there's something wrong with conversation
There is no MSConversation method insert(_:localizedChangeDescription:). Look at the docs and see.
Did you mean insert(_:completionHandler:)? If so, just delete the second parameter.

Swift: Extra argument 'error' in call
(3 answers)
Closed 5 years ago.
I have been trying to login for a while using php but I have a final bug that stops me from finishing. It turns out to give a bug in NSJSONSerialization where the error tells me: error extra argument in call. Then I will provide a screenshot so that the error is clearer and the code so you can help me since I am in a blocking moment and I do not know how to solve it. Thanks in advance

You can follow the quick fix sugestions. Doing so will let you end up like this:
do {
var json = try JSONSerialization.jsonObject(with: Data(), options: .mutableContainers)
if let parseJSON = json {
//your code
}
} catch {
//handle error
}
Unlike Objective C, as per the new methodolgy in Swift, errors are handled using try/catch block instead of passing the error object in the method.
Use the following code for Swift 3.
do {
var json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers)
if let parseJSON = json {
var resultValue:String = parseJSON["status"] as String!;
print("result: \(resultValue)")
if(resultValue=="Success")
{
NSUserDefaults.standardUserDefaults().setBool(true, forKey: "isUserLoggedIn");
NSUserDefaults.standardUserDefaults().synchronize();
self.dismissViewControllerAnimated(true, completion: nil);
}
}
} catch let error {
//Perform the error handling here
}
Following for Swift 2
do {
var json = try NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers)
if let parseJSON = json {
var resultValue:String = parseJSON["status"] as String!;
print("result: \(resultValue)")
if(resultValue=="Success")
{
NSUserDefaults.standardUserDefaults().setBool(true, forKey: "isUserLoggedIn");
NSUserDefaults.standardUserDefaults().synchronize();
self.dismissViewControllerAnimated(true, completion: nil);
}
}
} catch let error {
//Perform the error handling here

How to create a button which counts how many user presses and then activate a different sound after a certain number of presses?
#IBAction func button(_ sender: UIButton) {
var buttonCount: Int
buttonAnim.startCanvasAnimation()
let path = Bundle.main.path(forResource: "test", ofType:"wav")!
let url = URL(fileURLWithPath: path)
let path2 = Bundle.main.path(forResource: "stop-it", ofType:"mp3")!
let url2 = URL(fileURLWithPath: path2)
buttonCount = 0
buttonCount = buttonCount + 1
if buttonCount == 10 {
do {
let sound2 = try AVAudioPlayer(contentsOf: url2)
bombSoundEffect2 = sound2
sound2.play()
} catch {
// couldn't load file :(
}
}else{
do {
let sound = try AVAudioPlayer(contentsOf: url)
bombSoundEffect = sound
sound.play()
} catch {
// couldn't load file :(
}
}
}
Here's my button code, I wish make it add on into an Int variable and when that variable reaches 5, it will reset itself and also play a different sound.
edit: I've edited the code, but it says there that the if portion will never be executed.
Declare var buttonCount = 0 out side of the function, and rest it in if condition.
class ViewController: UIViewController {
#IBOutlet weak var dateLabelOutlet: UILabel!
var buttonCount: Int = 0
#IBAction func button(_ sender: UIButton) {
buttonAnim.startCanvasAnimation()
let path = Bundle.main.path(forResource: "test", ofType:"wav")!
let url = URL(fileURLWithPath: path)
let path2 = Bundle.main.path(forResource: "stop-it", ofType:"mp3")!
let url2 = URL(fileURLWithPath: path2)
buttonCount = buttonCount + 1
if buttonCount == 10 {
do {
let sound2 = try AVAudioPlayer(contentsOf: url2)
bombSoundEffect2 = sound2
sound2.play()
} catch {
// couldn't load file :(
}
}else{
do {
let sound = try AVAudioPlayer(contentsOf: url)
bombSoundEffect = sound
sound.play()
} catch {
// couldn't load file :(
}
}
}
}
I am using the following code to play music. It plays well :)
var backgroundMusicPlayer = AVAudioPlayer()
func playBackgroundMusic(filename: String) {
let url = NSBundle.mainBundle().URLForResource(filename, withExtension: nil)
guard let newURL = url else {
print("Could not find file: \(filename)")
return
}
do {
backgroundMusicPlayer = try AVAudioPlayer(contentsOfURL: newURL)
backgroundMusicPlayer.numberOfLoops = -1
backgroundMusicPlayer.prepareToPlay()
backgroundMusicPlayer.play()
} catch let error as NSError {
print(error.description)
}
}
playBackgroundMusic("music.wav")
However, I'd like to be able to keep the music playing only through certain transitions. Is this possible?
Cheers :)
I'm using this class that was written in Swift 1.2 and now I want to use it with Swift 2.0.
I get an error: Ambiguous use of 'subscript' # let artist = result["name"] as! String
} else if let jsonArtists = jsonResult["artists"] as? NSDictionary {
if let results:NSArray = jsonArtists["items"] as? NSArray {
dispatch_async(dispatch_get_main_queue(), {
self.searching = false
var suggestionResults: [spotifySearchResult] = []
for result in results {
let artist = result["name"] as! String
var sugresult = spotifySearchResult()
sugresult.artist = artist
if !suggestionResults.contains(sugresult) {
suggestionResults.append(sugresult)
}
}
handler(suggestionResults)
})
}
}
}
I tried different fixes such as let artist = (result["name"] as! String) or let artist = (result["name"] as! String) as! String
But nothing worked.
I know that the question was already post 4 times but, I can't find anyone explaining how to fix it in every case, only case by case.
Can someone explain me how to investigate to fix it? Not just only a fix for my case. I would prefer fix it by myself with your hints!
BTW what does mean subscript? Is subscript the thing between quotation mark? IMHO the error message is a bit vague...
EDIT:
class spotifySearchResult : NSObject {
var artist=""
var track=""
var duration=0
var spotifyURL = NSURL()
var spotifyURI = NSURL()
override func isEqual(theObject: AnyObject?) -> Bool {
if let myObject = theObject as? spotifySearchResult {
return (myObject.artist.uppercaseString == self.artist.uppercaseString && myObject.track.uppercaseString == self.track.uppercaseString)
}
return false
}
}
Subscription means to use the shorter syntax item["key"] for item.objectForKey["key"]
results seems to be an array of dictionaries so I suggest to cast down to a more specific type
if let results = jsonArtists["items"] as? [[String:AnyObject]] {
or even, if all values are guaranteed to be strings
if let results = jsonArtists["items"] as? [[String:String]] {
I just updated to Xcode7 and am trying to switch my project to using the Swift 2.0 Syntax when I ran into this error in a file from an open source library I'm using. Here's the relevant code:
public lazy var cookies:[String:NSHTTPCookie] = {
let foundCookies: [NSHTTPCookie]
if let responseHeaders = (self.response as? NSHTTPURLResponse)?.allHeaderFields {
foundCookies = NSHTTPCookie.cookiesWithResponseHeaderFields(responseHeaders, forURL:NSURL(string:"")!) as! [NSHTTPCookie]
} else {
foundCookies = []
}
var result:[String:NSHTTPCookie] = [:]
for cookie in foundCookies {
result[cookie.name] = cookie
}
return result
}()
The error reads: Cannot assign a value of type '[NSHTTPCookie]' to a value of type '[NSHTTPCookie]'
Is there something I'm missing here?
Change your code to this:
public lazy var cookies:[String:NSHTTPCookie] = {
let foundCookies: [NSHTTPCookie]
if let responseHeaders = (self.response as? NSHTTPURLResponse)?.allHeaderFields as? [String:String] {
foundCookies = NSHTTPCookie.cookiesWithResponseHeaderFields(responseHeaders, forURL:NSURL(string:"")!)
} else {
foundCookies = []
}
var result:[String:NSHTTPCookie] = [:]
for cookie in foundCookies {
result[cookie.name] = cookie
}
return result
}()
Changes:
if let responseHeaders ... line - did add as? [String:String], because allHeadersFields return type is [NSObject : AnyObject] and not [String:String] required by cookiesWithResponseHeaderFields...
removed as! [NSHTTPCookie] - it has no sense, because cookiesWithResponseHeaderFields return type is already [NSHTTPCookie]
Just check cookiesWithResponseHeaderFields signature:
class func cookiesWithResponseHeaderFields(headerFields: [String : String],
forURL URL: NSURL) -> [NSHTTPCookie]
Please read How do I ask a good question. At least, you should point out to lines where the problem is, etc.
