How to display temporary popup message on iPhone/iPad/iOS

Question

I\'d like to display a temporary message on the iPhone/iPad displaying confirmation of an action, or some quick status about some background activity.

Is there a st

Answer 1

Use UIAlertView. Here's a quick link to a simple example:

UIAlertView

Edited: Sorry, didn't see about disappearing on it's own. I think you need to have some confirmation by users of messages received. UIAlertView pretty much accomplishes that. Not sure if you have it gradually fade away unless you're in an app with a view that has a timer or event based delay that will show a view and then eventually remove it.

Second edit: Found a way to implement it. You can manually call the dismiss function after some set time that you've designated. (Sorry for the messy post) It would look something like this:

//Create UIAlertView alert
alert = [[UIAlertView alloc] initWithTitle:@"Title" message:@"Some message" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles: nil];

//After some time
[alert dismissWithClickedButtonIndex:0 animated:TRUE];

Answer 2

Create a class that inherits from UIAlertView. In your constructor just call [super init] and then add any view you want as a subview. You can even design this view in Interface Builder. Something like this:

- (id)initWithMessage:(NSString *)message dismissAfter:(NSTimeInterval)interval
{
  if ((self = [super init]))
  {
     CustomView * customView = [[[CustomView alloc] init] autorelease]; // or load from NIB
     [self addSubview:customView];
     [self performSelector:@selector(dismissAfterDelay) withObject:nil afterDelay:interval];
  }
  return self;
}

- (void)dismissAfterDelay
{
  [self dismissWithClickedButtonIndex:0 animated:YES]; 
}

To display your custom alert view just init it, and call show as with a regular UIAlertView.

CustomAlertView * cav = [[CustomAlertView alloc] initWithMessage:@"Doing Something];
[cav show];
[cav release];

As an nice side-effect, when you present this view the background will darken and you will get the nice wobbly animation for any alert view.

*Swift 2.2 Answer:

func showPopupWithTitle(title: String, message: String, interval: NSTimeInterval) {
    let alertController = UIAlertController(title: title, message: message, preferredStyle: .Alert)
    presentViewController(alertController, animated: true, completion: nil)
    self.performSelector(#selector(dismissAlertViewController), withObject: alertController, afterDelay: interval)
}

func dismissAlertViewController(alertController: UIAlertController) {
    alertController.dismissViewControllerAnimated(true, completion: nil)
}

showPopupWithTitle("Title", message: "Message", interval: 0.5)

Answer 4

You can use my own StatusAlert framework written in Swift. It gives you ability to show Apple system-like alert as well as present the same alert without an image, title or message anywhere in UIView.

It is available via Cocoapods and Carthage and supports iPhone X, Safe Areas layout, iPads and allows some customizations.

Similar answer to @marco-mustapic's, but without inheritance.

- (void)dismissAlert:(UIAlertView *)alertView
{
    [alertView dismissWithClickedButtonIndex:0 animated:YES];
}

- (void)showPopupWithTitle:(NSString *)title
                    mesage:(NSString *)message
              dismissAfter:(NSTimeInterval)interval
{
    UIAlertView *alertView = [[UIAlertView alloc]
           initWithTitle:title
                 message:message
                delegate:nil
        cancelButtonTitle:nil
        otherButtonTitles:nil
    ];
    [alertView show];
    [self performSelector:@selector(dismissAlert:)
               withObject:alertView
               afterDelay:interval
    ];
}

To use it:

[self showPopupWithTitle:@"Hi" message:@"I like pie" dismissAfter:2.0];

Throw it into a category on NSObject or something to always have it around.

Answer 6

I ended up creating my own class. Didn't inherit from UIAlertView. General structure is,

-(id)initWithText:(NSString *)msg {
    // Create a view. Put a label, set the msg
    CALayer *layer = self.layer;
    layer.cornerRadius = 8.0f;
    ...
    self.backgroundColor = [UIColor colorWithWhite:0 alpha:0.8];
    [self performSelector:@selector(dismiss:) withObject:nil afterDelay:2.0];
    [self setAutoresizesSubviews:FALSE];
    return self;
}


- (void)dismiss:(id)sender {
    // Fade out the message and destroy self
    [UIView animateWithDuration:0.5 
                 animations:^  { self.alpha = 0; }
                 completion:^ (BOOL finished) { [self removeFromSuperview]; }];
}
