写的一个scrollView里循环滚动新闻的控件，在updateForTopTalkArray方法中添加

if ([_containerView subviews].count) {
        for (UIView *view in [_containerView subviews]) {
            if ([view isKindOfClass:[DyTopTalkButton class]]) {
                [view removeFromSuperview];
            }
        }
    }

变回报错，下面是错误信息：

2015-11-28 17:42:51.793 WanFanTian[9068:2279758] *** Assertion failure in -[MASViewConstraint install], /Users/deyi/Documents/Deyi/WanFanTian/Pods/Masonry/Masonry/MASViewConstraint.m:345

其中MASViewConstraint.m:345的内容就是：

 @"couldn't find a common superview for %@ and %@",

同时按钮添加的监听方法无效，点击之后没有效果
望大牛能够帮忙解决!!!

详细代码如下：
