how to implement a pop up dialog box in ios  using -'ios,popup'

After a calculation, I want to display a pop up or alert box conveying a message to the user. Does anyone know where I can find more information about this?

Yup, a UIAlertView is probably what you're looking for. Here's an example:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No network connection" 
                                                message:@"You must be connected to the internet to use this app." 
[alert show];
[alert release];

If you want to do something more fancy, say display a custom UI in your UIAlertView, you can subclass UIAlertView and put in custom UI components in the init method. If you want to respond to a button press after a UIAlertView appears, you can set the delegate above and implement the - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex method.

You might also want to look at the UIActionSheet.

Hope this helps!

Since the release of iOS 8 the UIAlertView is now deprecated. Now you will use UIAlertController.

Here is a sample how it looks in Swift

    let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: UIAlertControllerStyle.Alert)
    let alertAction = UIAlertAction(title: "OK!", style: UIAlertActionStyle.Default) { (UIAlertAction) -> Void in }
    presentViewController(alert, animated: true) { () -> Void in }

As you can see the API allows us to implement callbacks both the action and when we are presenting the alert which is quite handy!

Different people who come to this question mean different things by a popup box. I highly recommend reading the Temporary Views documentation. My answer is largely a summary of this and other related documentation.


enter image description here

Alerts display a title and an optional message. The user must acknowledge it (a one-button alert) or make a simple choice (a two-button alert) before going on. You create an alert with a UIAlertController.

It is worth quoting the documentation's warning and advice about creating unnecessary alerts.

Action Sheet

enter image description here

Action Sheets give the user a list of choices. They appear either at the bottom of the screen or in a popover depending on the size and orientation of the device. As with alerts, a UIAlertController is used to make an action sheet. Before iOS 8, UIActionSheet was used, but now the documentation says:

Important: UIActionSheet is deprecated in iOS 8. (Note that UIActionSheetDelegate is also deprecated.) To create and manage action sheets in iOS 8 and later, instead use UIAlertController with a preferredStyle of UIAlertControllerStyleActionSheet.

Modal View

enter image description here

A modal view is a self-contained view that has everything it needs to complete a task. It may or may not take up the full screen. To create a modal view, use a UIPresentationController with one of the Modal Presentation Styles.

A Popover is a view that appears when a user taps on something and disappears when tapping off it. It has an arrow showing the control or location from where the tap was made. The content can be just about anything you can put in a View Controller. You make a popover with a UIPopoverPresentationController. (Before iOS 8, UIPopoverController was the recommended method.)

In the past popovers were only available on the iPad, but starting with iOS 8 you can also get them on an iPhone (see here, here, and here).

Notifications are sounds/vibrations, alerts/banners, or badges that notify the user of something even when the app is not running in the foreground.

A note about Android Toasts

enter image description here

In Android, a Toast is a short message that displays on the screen for a short amount of time and then disappears automatically without disrupting user interaction with the app.

People coming from an Android background want to know what the iOS version of a Toast is. Some examples of these questions can he found here, here, here, and here. The answer is that there is no equivalent to a Toast in iOS. Various workarounds that have been presented include:

  • Make your own with a subclassed UIView
  • Import a third party project that mimics a Toast
  • Use a buttonless Alert with a timer

However, my advice is to stick with the standard UI options that already come with iOS. Don't try to make your app look and behave exactly the same as the Android version. Think about how to repackage it so that it looks and feels like an iOS app.

Download this framework from Github

iOS Toast Alert Views

This examples work on you UIViewController, once you imported the Framework.

Example 1:

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

Example 2:

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