在使用UINavigationController+FDFullscreenPopGesture全屏手勢的時候與UIScrollview發(fā)生沖突。在官方的demo里 是這么寫的:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    if (self.contentOffset.x <= 0) {
        if ([otherGestureRecognizer.delegate isKindOfClass:NSClassFromString(@"_FDFullscreenPopGestureRecognizerDelegate")]) {
            return YES;
        }
    }
    return NO;
}

所以我們只需要新建一個UIScrollview分類，把這個方法放進去即可。
