如何制作约束使用视图数组中具有最高高度的视图

Question

假设我有4个视图，连续3个视图，另一个视图中有1个视图。第一排的那些有动态高度，我们不知道它们有多高。

我想从这张图片中获得结果：

基本上我想在第一行中将View 4的顶部设置为最高视图的底部。我怎样才能做到这一点？

Answer 1

使用view4.topAnchor.constraint(greaterThanOrEqualTo: view1.bottomAnchor, constant: 10).isActive = true view4.topAnchor.constraint(greaterThanOrEqualTo: view2.bottomAnchor, constant: 10).isActive = true view4.topAnchor.constraint(greaterThanOrEqualTo: view3.bottomAnchor, constant: 10).isActive = true ：

views.py

recent_results_ids = []
[recent_results_ids.append(i.id) for i in Results.objects.raw('SELECT MAX(id) id FROM results WHERE hide = 0 GROUP BY site ORDER BY MAX(created) DESC LIMIT 10')]
recent_results = Results.objects.filter(id__in=recent_results_ids).order_by('-id')

Answer 2

将 var React = require('react'); var ReactDOM = require('react-dom'); var {HashRouter, Route,Link, hashHistory, Switch} = require('react-router-dom'); var Main = require('Main'); var Weather = require('Weather'); var About = require('About'); var Examples = require('Examples'); ReactDOM.render( <HashRouter> <div> <Route exact path="/about" component={About} /> <Route exact path="/examples" component={Examples} /> <Route exact path= "/" component={Main} /> </div> </HashRouter> ,document.getElementById('app') ); ，View1和View2放在View3（或常规UIStackView）中，然后在此UIView之间添加约束{ {1}}和bottom的{​​{1}}
