fix cash on Observing

[captain-black]

    if (self.infiniteScrollingView.isObserving) {
        [self removeObserver:self.infiniteScrollingView forKeyPath:@"contentOffset"];
        [self removeObserver:self.infiniteScrollingView forKeyPath:@"contentSize"];
        [self.infiniteScrollingView resetScrollViewContentInset];
        self.infiniteScrollingView.isObserving = NO;
    }

[self.infiniteScrollingView resetScrollViewContentInset]; will make scrolling and trigger this method again.

you should do: if (self.infiniteScrollingView.isObserving) { self.infiniteScrollingView.isObserving = NO; [self removeObserver:self.infiniteScrollingView forKeyPath:@"contentOffset"]; [self removeObserver:self.infiniteScrollingView forKeyPath:@"contentSize"]; [self.infiniteScrollingView resetScrollViewContentInset]; }

This kind of BUG is also in the other method, fix them like above
