在Objective-C中實現易讀鏈式動畫寫法：JHChainableAnimations

JHChainableAnimations讓你能夠在Objective-C中實現易讀鏈式動畫寫法。

老的寫法

    [UIView animateWithDuration:1.0 delay:0.0 usingSpringWithDamping:0.8 initialSpringVelocity:1.0 options:0 animations:^{ CGPoint newPosition = self.myView.frame.origin;
                            newPosition.x += 50;
                            self.myView.frame.origin = newPosition;
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:0.5 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
            self.myView.backgroundColor = [UIColor purpleColor];
        } completion:nil];
    }];

</h3>

利用JHChainableAnimations只要一行代碼就能搞定

新的寫法(JHChainableAnimations!!!)

self.myView.moveX(50).spring.thenAfter(1.0).makeBackground([UIColor purpleColor]).easeIn.animate(0.5);
