发现一个问题，应该是手误 #14

在 ESRefreshHeaderView这个类中有个小小的问题，或者说，我没看明白吧，

public override func startAnimating() {

...... // Navigation will automatically add 64, we are here to deal with part of the logic if scrollView.contentInset.top != insets.top || scrollView.contentOffset.x != -insets.top { UIView .animateWithDuration(0.2, animations: { scrollView.contentInset = insets scrollView.contentOffset = CGPoint.init(x: scrollView.contentOffset.x, y: -insets.top) }) } ...... }

您能解释一下，if判断的第二个条件是什么意思？是不是scrollView.contentOffset.y != -inset.top？
