Question

这适用于OS X：

#include <iostream>
#include <vector>
#include <algorithm>
#include <cmath>

int main() {
    std::vector<double> v{9.2, 0.4, 2.5, 6.5, 4.3, 3.1, 9.7, 0.9, 1.2, 2.2, 1.09, 1.3};
    if (v.size()) {
      if (v.size() % 2) {
        std::cout << "Middle: " << v[v.size()/2] << "\n";
      } else {
        std::cout << "Middle: " << v[v.size()/2 - 1] << "\n";
      }
      std::nth_element(v.begin(), v.begin() + v.size()/2, v.end());
      if (v.size() % 2) {
        std::cout << "Median " << v[v.size()/2] << '\n';
      } else {
        auto second = v[v.size()/2];
        std::nth_element(v.begin(), v.begin() + v.size()/2 - 1, v.end());
        auto first = v[v.size()/2 - 1];
        std::cout << "Median " << " " << (first + second)/2 << '\n';
      }
      auto result = std::minmax_element(v.begin(), v.end());
      std::cout << "Min: " << *result.first << "\nMax: " << *result.second << "\n";
    }
    return 0;
}

但在macOS崩溃：

WebPreferences *prefs = [webView preferences];
[prefs setDeveloperExtrasEnabled:YES];

WebInspector *inspector = [[WebInspector alloc] initWithWebView:webView];

这个私有API被抛弃了吗？

代码取from here。

他们已将其重命名为：http://trac.webkit.org/changeset/189654

TLDR：

WebInspector *inspector = [WebInspector alloc];

if ([inspector respondsToSelector:@selector(initWithWebView:)])
    [inspector initWithWebView:webView];
else
    [inspector initWithInspectedWebView:webView];

如果将来有变化，请查看WebKit source code。

如何在10.12 Sierra上打开Web Inspector？
