Question

我在这做什么？我正在尝试构建一个Instagram克隆，并在我的家庭视图控制器中显示帖子应该显示的内容。我使用表视图进行导航，并且该表视图有2个具有不同标识符的单元格。单元格编号1它是一个标题，用于将users表中的数据添加到我的用户名标签和配置文件图像中。它的帖子数据如图像和标题，它的帖子数据和帖子数量为2。我使用firebase数据库。问题是我的布局不像我想要的那样显示它给出了这个错误：

2017-12-31 00:00:31.920010+0300 Instgram Clone[2165:463944] [LayoutConstraints] Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it.

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x604000284ba0 UIButton:0x7fdc874433e0.height == 30   (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.

只是为了知识：

postcell =视图标题

imagecell =视野

header cell constraints

post cell constraints

Continue with post cell constraints

this image to my result layout when the running app

当我将内容视图修复为高时，

我的新错误消息：
