ios9 $rootScope 上的角度路由：infdig 错误

Question

在 ios8 中工作的 Angular 应用程序中的路由在 ios9 中产生 [$rootScope:infdig] 错误。 ngRoute 和 ui.router 我都试过了，但结果是一样的。

Error: [$rootScope:infdig] http://errors.angularjs.org/1.4.3/$rootScope/infdig?p0=10&p1=%5B%5D

有什么解决办法吗？

Answer 1

即使这被标记为此问题的重复。这是解决此问题的最佳方法。

ionic app iOS 9 problems [$rootScope:infdig] 10 $digest() iterations reached

这篇文章中选择的答案会将您引导至此插件，该插件使用 Angular 修补所有 iOS9 问题。 https://gist.github.com/IgorMinar/863acd413e3925bf282c

此补丁适用于Angular 1.2.0 – 1.4.5，并且所有较新版本的 Angular 都将嵌入此修复。

显然解决了这个问题，但在其他版本的 Angular 中没有。
