bouncinganimation's Introduction

BouncingAnimation

This is a bouncing animation on iOS platform written in objective-c.And it's merely a 2D animation, which is not working in 3D transform.
The whole project is a sample project with the animation components(BouncingAnimation.h/.m).

Install

Cocoapods

Add code below to your Podfile, and change 'Myapp' to your target name:

target 'MyApp' do
pod 'BouncingAnimation', '~> 1.0.0'
end

Then run pod install in your terminal.

Source code

Download the project here and drag the BouncingAnimation.h/.m files to your project.

After adding BouncingAnimation into your project, you can simply import BouncingAnimation.h to use it.

How to use it?

Use the public factory method to create custom bouncing animation. Here are some examples:

	CATransform3D fromt = CATransform3DIdentity;
	CATransform3D tot = CATransform3DMakeScale(2, 2, 1);
    
	BouncingAnimation *anim = [BouncingAnimation animationWithKeypath:@"transform"
                                                            fromValue:[NSValue valueWithCATransform3D:fromt]
                                                              toValue:[NSValue valueWithCATransform3D:tot]];

	[view.layer addAnimation:anim forKey:@""];

	CGFloat fromf = _view.layer.position.x;
	CGFloat tof = fromf - _view.bounds.size.width;
    
	BouncingAnimation *anim = [BouncingAnimation animationWithKeypath:@"position.x"
                                                            fromValue:[NSNumber numberWithFloat:fromf]
                                                              toValue:[NSNumber numberWithFloat:tof]];
                                                              
	[view.layer addAnimation:anim forKey:@""];

	CGRect fromr = _view.layer.frame;
	CGRect tor = CGRectInset(fromr, 10, 10);
    
	BouncingAnimation *anim = [BouncingAnimation animationWithKeypath:@"bounds"
                                                            fromValue:[NSValue valueWithCGRect:fromr]
                                                              toValue:[NSValue valueWithCGRect:tor]];
                                                              
	[view.layer addAnimation:anim forKey:@""];
