NumberMorphView
NumberMorphView
a view like label for displaying numbers which animate with transition using a technique called number tweening or number morphing.
Usage
To run the example project, clone the repo, and run pod install
from the Example directory first.
Interface builder
- Drag a UIView into your view controller.
- Change the class to
NumberMorphView
in the identity inspector. - Change intrinsic size from default to placeholder in the size inspector.
- Create an IBOutlet in your view controller.
Set the digit of number view as shown below:
numberView.currentDigit = 5;
Animate to nextDigit as shown below.
numberView.nextDigit = 8;
From code
NumberMorphView
can be used with or without auto layout. Usage of intrinsic content size is recommended. Preferred aspect ratio of the view is 13 : 24.
let numberView = NumberMorphView();
numberView.fontSize = 64;
numberView.currentDigit = 5;
let preferedSize = numberView.intrinsicContentSize();
numberView.frame = CGRect(x: 10, y: 10, width: preferedSize.width, height: preferedSize.height);
self.view.addSubview(numberView);
dispatch_after(5, dispatch_get_main_queue()) {
numberView.nextDigit = 7;
}
Note: Intrinsic content size is changed after setting fontSize
.
Customizing animations
- To set the animation duration:
numberView.animationDuration = 4;
- To change the type of animation, set the interpolator.
numberView.interpolator = NumberMorphView.SpringInterpolator();
Already available interpolators are LinearInterpolator
, OvershootInterpolator
, SpringInterpolator
, BounceInterpolator
, AnticipateOvershootInterpolator
, and CubicHermiteInterpolator
. Also you can add new interpolators. The interpolator class needs to conform to InterpolatorProtocol
as shown below:
class MyLinearInterpolator: InterpolatorProtocol {
func getInterpolation(x: CGFloat) -> CGFloat {
return x;
}
}
Requirements
- iOS 8.0+
- Swift 2.2
