About

JRMFloatingAnimation is an ObjC library used to create floating image views:

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

To create the animation view:

self.floatingView = [[JRMFloatingAnimationView alloc] initWithStartingPoint:self.view.center];
[self.floatingView addImage:[UIImage imageName:@"myImage"]];
[self.view addSubview:self.floatingView];

To animate the view:

[self.floatingView animate];

You can add as many images to your view as you want, and they will be used randomly. Note that the images should be square.

There are a variety of different settings you can add to your animation view.

• startingPointWidth - Varies the x of the starting point, with the starting point y being the middle. default is 0.
• maxAnimationHeight - The maximum height that the animation may go. Default is the distance from the top of the frame to the starting point y value.
• minAnimationHeight - The minimum height that the animation may go. If this is larger than the maxAnimationHeight, they will swap. Default is 1/3 the maxAnimationHeight .
• animationWidth - The maximum "width" of the bezier path's control points fro the object's starting point. Changing this may give you unexpected results. Defaults:
  • JRMFloatingShape: The object's size * 2.
  • JRMFloatingShapeCurveLeft: The distance between the starting point x and the let edge of the frame.
  • JRMFloatingShapeCurveRight: The distance between the starting point x and the right edge of the frame.
  • JRMFloatingShapeTriangleUp: The width of the frame.
• pop: Gives the impression of the images "popping" before they are removed from the view. Default NO.
• maxFloatObjectSize: The maximum size a floating object can be. Default is 20.
• minFloatObjectSize: The minimum size a floating object can be. If the minFloatObjectSize < maxFloatObjectSize, both sizes become the minFloatObjectSize. Default is 10.
• floatingShape: The "shape" that the animation can take. Default is JRMFloatingShapeStraight.
  • JRMFloatingShapeTriangleUp - Floats up in a cone shape from the starting point.
  • JRMFloatingShapeStraight - Floats straight up from the starting point.
  • JRMFloatingShapeCurveLeft - Floats up and curves to the left.
  • JRMFloatingShapeCurveRight - Floats up and curves to the right.
• fadeOut: If the floating object's alpha should fade out before disappearing from the view. Default NO.
• varyAlpha: If the floating object's alpahs should vary (to give a more randomized look). Default NO.
• animationDuration: The speed of the animation. Default 2.
• removeOnCompletion: If the floating object should be removed from the superview when the animation is finished. Default YES.
• imageViewAnimationCompleted: A completion block to call whenever an image view is finished animating. It will return the image view. (See the JRMDemoBalloonViewController.m file for an example.)
