Error loading page Domain: WebKitErrorDomain Error Code: 101

使用 WebView 组件，loading的过程中出现这个错误。

解决方案： webVIew 里面加

renderError={ (e) => {
                        if (e === 'WebKitErrorDomain') {
                            return
                        }
                      }
                    }

React native ERROR Packager can't listen on port 8081

这个问题，其实就是端口和正在运行的程序的端口冲突了，最简单的办法就是把正在运行的项目停掉，然后重新对当前的项目npm start。也可以用终端代码操作：

$ react-native start --port=8088
$ netstat -a -b -o
$ taskkill /pid 1234

初始化React-native,执行run-ios报错了
