ARAnimation is an Core Animation library to make you animations easily.

Features

  • Layer animations
  • Layer Spring Animations
  • Custom TimingFunction(easing funtion)
  • Official style block Animations

Install

Cocoapods

Manually

  • just drag demo source ducument to your project

Usage

Example1

[UIView AR_animationWithDuration:2.0
                          animations:^{
                              self.redView.layer.rotation = M_PI*10;
                              self.redView.layer.cornerRadius = 50;
                          }];

Example2 (Multistep animations block Nested)

 void(^animation4)(void) = ^{
        [self.view setNeedsLayout];
        [UIView AR_animationWithDuration:0.5 delay:0.0 easing:kAREasingCurveBounceOut animations:^{
            [self.view layoutIfNeeded];
        } completion:^{
            NSLog(@"all animations completion");
        }];
    };
    
    void(^animation3)(void) = ^{
        [UIView AR_springAnimationWithDuration:1 animations:^{
            self.redView.layer.scale = 2;
            self.yellowView.layer.scale = 1;
            self.redView.layer.position = CGPointMake(CGRectGetMidX(self.view.bounds), 250);
            self.yellowView.layer.position = CGPointMake(CGRectGetMidX(self.view.bounds), 250);
        } completion:animation4];
    };
    
    void(^animation2)(void) = ^{
        [UIView AR_springAnimationWithDuration:1.5 animations:^{
            self.redView.layer.cornerRadius = CGRectGetMidX(self.redView.bounds);
            self.yellowView.layer.cornerRadius = CGRectGetMidX(self.yellowView.bounds);
        } completion:animation3];
    };
    
    void(^animation1)(void) = ^{
        [UIView AR_animationWithDuration:0.5 animations:^{
            self.redView.layer.position = CGPointMake(CGRectGetMidX(self.view.bounds), 150);
            self.yellowView.layer.position = CGPointMake(CGRectGetMidX(self.view.bounds), 150);
            self.redView.layer.scaleX = 1.3;
            self.yellowView.layer.scaleY = 1.3;
        } completion:animation2];
    };
    
    
    [UIView AR_animationWithDuration:2 animations:^{
        self.redView.backgroundColor = [self randomColor];
        self.yellowView.backgroundColor = [self randomColor];
        self.yellowView.alpha = 1;
        
        self.redView.layer.rotation = M_PI*4;
        self.yellowView.layer.rotation = -M_PI*4;
    } completion:animation1];
