老的写法
[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]; }];
利用JHChainableAnimations只要一行代码就能搞定
新的写法(JHChainableAnimations!!!)
self.myView.moveX(50).spring.thenAfter(1.0).makeBackground([UIColor purpleColor]).easeIn.animate(0.5);
