Afficher un message dans iOS qui a les mêmes fonctionnalités que Toast dans Android

J'ai besoin de savoir s'il existe une méthode dans iOS qui se comporte comme des messages Toast dans Android. Autrement dit, j'ai besoin d'afficher un message qui est automatiquement rejeté après quelques secondes. Ceci est similaire à la fonctionnalité de la classe Toast dans l'environnement Android.

Vous pouvez utiliser MBProgressHUDproject.

Utilisez le mode HUD MBProgressHUDModeTextpour un comportement de type toast,

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];

// Configure for text only and offset down
hud.mode = MBProgressHUDModeText;
hud.label.text = @"Some message...";
hud.margin = 10.f;
hud.yOffset = 150.f;
hud.removeFromSuperViewOnHide = YES;

[hud hideAnimated:YES afterDelay:3];

NSString *message = @"Some message...";

UIAlertView *toast = [[UIAlertView alloc] initWithTitle:nil
                                                message:message
                                               delegate:nil
                                      cancelButtonTitle:nil
                                      otherButtonTitles:nil, nil];
[toast show];

int duration = 1; // duration in seconds

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [toast dismissWithClickedButtonIndex:0 animated:YES];
});

Utilisation de UIAlertViewController pour iOS 9 ou version ultérieure

NSString *message = @"Some message...";

UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil
                                                               message:message
                                                        preferredStyle:UIAlertControllerStyleAlert];

[self presentViewController:alert animated:YES completion:nil];

int duration = 1; // duration in seconds

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, duration * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [alert dismissViewControllerAnimated:YES completion:nil];
});

Swift 3.2

let message = "Some message..."
let alert = UIAlertController(title: nil, message: message, preferredStyle: .alert)
self.present(alert, animated: true)

// duration in seconds
let duration: Double = 5

DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + duration) {
    alert.dismiss(animated: true)
}

Sous Android, un toast est un court message qui s'affiche à l'écran pendant une courte période de temps, puis disparaît automatiquement sans perturber l'interaction de l'utilisateur avec l'application.

Donc, beaucoup de gens venant d'un arrière-plan Android veulent savoir ce qu'est la version iOS d'un Toast. Outre la question actuelle, d'autres questions similaires peuvent être trouvées ici , ici et ici . La réponse est qu'il n'y a pas d'équivalent exact à un toast dans iOS . Diverses solutions de contournement qui ont été présentées, cependant, y compris

• faire votre propre toast avec un UIView(voir ici , ici , ici et ici )
• importer un projet tiers qui imite un Toast (voir ici , ici , ici et ici )
• en utilisant une alerte sans bouton avec une minuterie (voir ici )

Cependant, mon conseil est de s'en tenir aux options d'interface utilisateur standard déjà fournies avec iOS. N'essayez pas de donner à votre application le même aspect et le même comportement que la version Android. Réfléchissez à la façon de le reconditionner pour qu'il ressemble et se sente à une application iOS. Voir le lien suivant pour quelques choix.

• Vue d'ensemble des options iOS standard pour afficher temporairement des informations à un utilisateur.

Envisagez de redéfinir l'interface utilisateur de manière à transmettre les mêmes informations. Ou, si les informations sont très importantes, une alerte pourrait être la réponse.

Swift 4

Et cette petite astuce?

func showToast(controller: UIViewController, message : String, seconds: Double) {
    let alert = UIAlertController(title: nil, message: message, preferredStyle: .alert)
    alert.view.backgroundColor = UIColor.black
    alert.view.alpha = 0.6
    alert.view.layer.cornerRadius = 15

    controller.present(alert, animated: true)

    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + seconds) {
        alert.dismiss(animated: true)
    }
}

Exemple d'appel:

showToast(controller: self, message : "This is a test", seconds: 2.0)

Production:

Swift 3

Pour une solution simple sans code tiers:

Utilisez simplement un UIAlertController normal mais avec style = actionSheet (regardez le code ci-dessous)

let alertDisapperTimeInSeconds = 2.0
let alert = UIAlertController(title: nil, message: "Toast!", preferredStyle: .actionSheet)
self.present(alert, animated: true)
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + alertDisapperTimeInSeconds) {
  alert.dismiss(animated: true)
}

L'avantage de cette solution:

1. Android comme le message Toast
2. Toujours iOS Look & Feel

Pour Swift 3 et 4 :

Utiliser la bibliothèque Toaster

Toast(text: "Hello, world!", duration: Delay.long)

Pour Swift 2 :

Utilisez JLToast

Si vous en voulez un avec iOS Style, téléchargez ce framework depuis Github

Structure de vue d'alertes Toast iOS

Ces exemples fonctionnent sur vous UIViewController, une fois que vous avez importé le Framework.

Exemple 1:

//Manual 
let tav = ToastAlertView()
tav.message = "Hey!"
tav.image = UIImage(named: "img1")!
tav.show()
//tav.dismiss() to Hide

Exemple 2:

//Toast Alert View with Time Dissmis Only
self.showToastAlert("5 Seconds",
                image: UIImage(named: "img1")!,
                hideWithTap: false,
                hideWithTime: true,
                hideTime: 5.0)

    return rect.size.height
}
}

Usage:

  self.view.makeToast(message: "Simple Toast")
  self.view.makeToast(message: "Simple Toast", duration: 2.0, position:HRToastPositionTop)

  self.view.makeToast(message: "Simple Toast", duration: 2.0, position: HRToastPositionCenter, image: UIImage(named: "ic_120x120")!)

  self.view.makeToast(message: "It is just awesome", duration: 2.0, position: HRToastPositionDefault, title: "Simple Toast")

  self.view.makeToast(message: "It is just awesome", duration: 2.0, position: HRToastPositionCenter, title: "Simple Toast", image: UIImage(named: "ic_120x120")!)

  self.view.makeToastActivity()
  self.view.makeToastActivity(position: HRToastPositionCenter)
  self.view.makeToastActivity(position: HRToastPositionDefault, message: "Loading")
  self.view.makeToastActivityWithMessage(message: "Loading")

  // Hide Toast
  self.view.hideToast(toast: self.view)
  self.view.hideToast(toast: self.view, force: true)
  self.view.hideToastActivity()

Pour ceux qui utilisent Xamarin.IOS, vous pouvez faire comme ceci:

new UIAlertView(null, message, null, "OK", null).Show();

en utilisant UIKit; est requis.

Pour moi, cette solution fonctionne bien: https://github.com/cruffenach/CRToast

Exemple comment l'utiliser:

    NSDictionary *options = @{
                          kCRToastTextKey : @"Hello World!",
                          kCRToastTextAlignmentKey : @(NSTextAlignmentCenter),
                          kCRToastBackgroundColorKey : [UIColor redColor],
                          kCRToastAnimationInTypeKey : @(CRToastAnimationTypeGravity),
                          kCRToastAnimationOutTypeKey : @(CRToastAnimationTypeGravity),
                          kCRToastAnimationInDirectionKey : @(CRToastAnimationDirectionLeft),
                          kCRToastAnimationOutDirectionKey : @(CRToastAnimationDirectionRight)
                          };
[CRToastManager showNotificationWithOptions:options
                            completionBlock:^{
                                NSLog(@"Completed");
                            }];

Syntaxe Swift 4 pour un délai de 3 secondes:

present(alertController, animated: true, completion: nil)

DispatchQueue.main.asyncAfter(deadline: .now() + 3) {                 
    self.dismiss(animated: true, completion: nil)     
} 

Implémentation rapide d'Android Toast en utilisant Alert qui se dissipent au bout de 3 secondes.

    func showAlertView(title: String?, message: String?) {
    let alertController = UIAlertController(title: title, message: message, preferredStyle: .Alert)
    let okAction = UIAlertAction(title: "OK", style: .Cancel, handler: nil)
    alertController.addAction(okAction)
    self.presentViewController(alertController, animated: true, completion: nil)


    let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(3 * Double(NSEC_PER_SEC)))
    dispatch_after(delayTime, dispatch_get_main_queue()) {
        print("Bye. Lovvy")
        alertController.dismissViewControllerAnimated(true, completion: nil)
    }
}

Pour l'appeler simplement:

self.showAlertView("Message sent...", message: nil)

Pour Swift 2.0 et compte tenu de https://stackoverflow.com/a/5079536/6144027

                //TOAST
                let alertController = UIAlertController(title: "", message: "This is a Toast.LENGTH_SHORT", preferredStyle: .Alert)
                self!.presentViewController(alertController, animated: true, completion: nil)
                let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(2.0 * Double(NSEC_PER_SEC)))
                dispatch_after(delayTime, dispatch_get_main_queue()) {
                    alertController.dismissViewControllerAnimated(true, completion: nil)
                }

Voici votre solution:
mettez le code ci-dessous dans votre projet Xcode et profitez-en,

- (void)showMessage:(NSString*)message atPoint:(CGPoint)point {
const CGFloat fontSize = 16;

UILabel* label = [[UILabel alloc] initWithFrame:CGRectZero];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont fontWithName:@"Helvetica-Bold" size:fontSize];
label.text = message;
label.textColor = UIColorFromRGB(0x07575B);
[label sizeToFit];

label.center = point;

[self.view addSubview:label];

[UIView animateWithDuration:0.3 delay:1 options:0 animations:^{
    label.alpha = 0;
} completion:^(BOOL finished) {
    label.hidden = YES;
    [label removeFromSuperview];
}];
}

Comment utiliser ?

[self showMessage:@"Toast in iOS" atPoint:CGPointMake(160, 695)];

Encore une fois, si vous utilisez IOS sur Xamarin, il existe un nouveau composant appelé BTProgressHUD dans le magasin de composants

1) Téléchargez toast-notifications-ios depuis ce lien

2) allez dans Targets -> Build Phases et ajoutez -fno-objc-arc aux "sources du compilateur" pour les fichiers pertinents

3) créer une fonction et #import "iToast.h"

-(void)showToast :(NSString *)strMessage {
    iToast * objiTost = [iToast makeText:strMessage];
    [objiTost setFontSize:11];
    [objiTost setDuration:iToastDurationNormal];
    [objiTost setGravity:iToastGravityBottom];
    [objiTost show];
}

4) appelez où vous devez afficher un message toast

[self showToast:@"This is example text."];

J'ai pensé à un moyen simple de porter un toast! en utilisant UIAlertController sans bouton! Nous utilisons le texte du bouton comme message! tu piges? voir ci-dessous le code:

func alert(title: String?, message: String?, bdy:String) {
    let alertController = UIAlertController(title: title, message: message, preferredStyle: .Alert)
    let okAction = UIAlertAction(title: bdy, style: .Cancel, handler: nil)
    alertController.addAction(okAction)
        self.presentViewController(alertController, animated: true, completion: nil)


    let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(2 * Double(NSEC_PER_SEC)))
    dispatch_after(delayTime, dispatch_get_main_queue()) {
        //print("Bye. Lovvy")
        alertController.dismissViewControllerAnimated(true, completion: nil) 
    }    
}

utilisez-le comme ceci:

self.alert(nil,message:nil,bdy:"Simple Toast!") // toast
self.alert(nil,message:nil,bdy:"Alert") // alert with "Alert" button

C'est ce que j'ai fait dans Swift 3.0. J'ai créé l'extension UIView et j'ai appelé self.view.showToast (message: "Message Here", durée: 3.0) et self.view.hideToast ()

extension UIView{
var showToastTag :Int {return 999}

//Generic Show toast
func showToast(message : String, duration:TimeInterval) {

    let toastLabel = UILabel(frame: CGRect(x:0, y:0, width: (self.frame.size.width)-60, height:64))

    toastLabel.backgroundColor = UIColor.gray
    toastLabel.textColor = UIColor.black
    toastLabel.numberOfLines = 0
    toastLabel.layer.borderColor = UIColor.lightGray.cgColor
    toastLabel.layer.borderWidth = 1.0
    toastLabel.textAlignment = .center;
    toastLabel.font = UIFont(name: "HelveticaNeue", size: 17.0)
    toastLabel.text = message
    toastLabel.center = self.center
    toastLabel.isEnabled = true
    toastLabel.alpha = 0.99
    toastLabel.tag = showToastTag
    toastLabel.layer.cornerRadius = 10;
    toastLabel.clipsToBounds  =  true
    self.addSubview(toastLabel)

    UIView.animate(withDuration: duration, delay: 0.1, options: .curveEaseOut, animations: {
        toastLabel.alpha = 0.95
    }, completion: {(isCompleted) in
        toastLabel.removeFromSuperview()
    })
}

//Generic Hide toast
func hideToast(){
    if let view = self.viewWithTag(self.showToastTag){
        view.removeFromSuperview()
    }
  }
}
