Animated popover that pops out of a frame. You can specify the direction of the popover and the arrow that points to its origin. Color, border radius and font can be easily customized. This popover can be used to leave subtle hints about your UI and provide fun looking onboarding popups.

Versioning notes

With version 2.0.0 the library was re-written in Swift, and the API was slightly updated. Checkout version 1.5.x for the previous Objective-C implementation.

Version 3.0.0 introduces Swift 4 support, 3.5.0 Swift 4.2.

Setup with CocoaPods

  • Add pod 'AMPopTip' to your Podfile
  • Run pod install
  • Run open App.xcworkspace

Setup with Carthage

  • Add github "andreamazz/AMPopTip"
  • Run carthage update
  • Add AMPopTip.framework in your project

Usage

The API is fairly straight forward, you can show and hide the popover at any time.

Showing the popover

You must specify the text that you want to display alongside the popover direction, its max width, the view that will contain it and the frame of the view that the popover's arrow will point to.

let popTip = PopTip()
popTip.show(text: "Hey! Listen!", direction: .up, maxWidth: 200, in: view, from: someView.frame)

You can also display the popover in the center, with no arrow, in this case the from can be the whole view:

popTip.show(text: "Hey! Listen!", direction: .none, maxWidth: 200, in: view, from: view.frame)

Coordinate system

Please note that the frame you are intended to provide needs to refer to the absolute coordinate system of the view you are presenting the popover in. This means that if you are presenting the popover in a view, pointing to a nested subview, you'll need to convert its frame using UIKit's convertRect(_:toView:). Read the reference here.

Showing a custom view

You can provide a custom view that will be wrapped in the PopTip and presented.

let customView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
// Configure your view
popTip.show(customView: customView, direction: .down, in: view, from: someView.frame)

Dismissing the popover

You can hide the popover by calling:

popTip.hide()

Or you can specify the duration of the popover:

popTip.show(text: "Hey! Listen!", direction: .up, maxWidth: 200, in: view, from: someView.frame, duration: 3)

You can also let the user dismiss the popover by tapping on it:

popTip.shouldDismissOnTap = true

You can add a block that will be fired when the user taps the PopTip...

popTip.tapHandler = { popTip in
  print("\(popTip) tapped")
}

... when the popover is shown...

popTip.appearHandler = { popTip in
  print("\(popTip) appeared")
};

... or when the popover is dismissed:

popTip.dismissHandler = { popTip in
  print("\(popTip) dismissed")
}

popTip.tapOutsideHandler = { _ in
  print("tap outside")
}

popTip.swipeOutsideHandler = { _ in
  print("swipe outside")
}

Updating the PopTip

You can update the text, attributed text, or custom view to a PopTip already visible:

popTip.update(text: "New string")
popTip.update(attributedText: someAttributedString)
popTip.update(customView: someView)

The position can also be changed by updating the from property:

let here = CGRect(x: 100, 100, 10, 10)
let there = CGRect(x: 400, 400, 10, 10)

popTip.show(text: "Hey! Listen!", direction: .up, maxWidth: 200, in: view, from: here)
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
  popTip.from = there
}

Custom entrance animation

You can choose which animation should be performed when the popTip is displayed:

popTip.entranceAnimation = .scale;

Available animations:

PopTipEntranceAnimation.scale,
PopTipEntranceAnimation.transition,
PopTipEntranceAnimation.none,
PopTipEntranceAnimation.custom

PopTipEntranceAnimation.custom

You can provide your own animation block when using PopTipEntranceAnimation.custom:

popTip.entranceAnimationHandler = { [weak self] completion in
  guard let `self` = self else { return }
  self.popTip.transform = CGAffineTransform(rotationAngle: 0.3)
  UIView.animate(withDuration: 0.5, animations: {
    self.popTip.transform = .identity
  }, completion: { (_) in
    completion()
  })
}

This sample makes the PopTip rotate on entrance. Make sure to call the completion block when the animation is done. Also note that the animation is fired as soon as the PopTip is added as subview.

Action animations

Action animations are subtle animations that can be performed to get the user's attention. Set your preferred animation:

popTip.actionAnimation = .bounce()

Available animations:

PopTipActionAnimation.bounce,
PopTipActionAnimation.float,
PopTipActionAnimation.pulse,
PopTipActionAnimation.none

The animation is fired as soon as the popover enters the scene and completes its entrance animation, if startActionAnimationOnShow is set to true.

Customize the animations

You can pass a custom value as an associated value to customize the action animation:

popTip.actionAnimation = .bounce(16) // This will bounce for 16px instead of the default value

AMPopTip bounce

Customizing the arrow position

The arrow is centered by default, and moves to avoid the edge of the screen. You can manually change the offset from the center using the bubbleOffset property.

Customization

Use the appearance proxy to customize the popover before creating the instance, or just use its public properties:

textColor = <#UIColor#>;
textAlignment = <#NSTextAlignment#>
bubbleColor = <#UIColor#>
borderColor = <#UIColor#>
borderWidth = <#CGFloat#>
cornerRadius = <#CGFloat#> // Popover's border radius
rounded = <#Bool#> // If set to YES the radius will equal frame.height / 2
offset = <#CGFloat#> // Offset between the popover and the origin
font = <#UIFont#>
padding = <#CGFloat#>
edgeInsets = <#UIEdgeInsets#>
arrowSize = <#CGSize#>
animationIn = <#TimeInterval#>
animationOut = <#TimeInterval#>
delayIn = <#TimeInterval#>
delayOut = <#TimeInterval#>
entranceAnimation = <#PopTipEntranceAnimation#>
actionAnimation = <#PopTipActionAnimation#>
actionAnimationIn = <#TimeInterval#>
actionAnimationOut = <#TimeInterval#>
actionDelayIn = <#TimeInterval#>
actionDelayOut = <#TimeInterval#>
edgeMargin = <#CGFloat#>
bubbleOffset = <#CGFloat#> // Offset between the bubble and the arrow
arrowRadius = <#CGFloat#>
shadowOpacity = <#Float#>
shadowRadius = <#Float#>
shadowOffset = <#CGSize#>
shadowColor = <#UIColor#>
