在 Typescript 2.0 中使用 @type 类型定义 基于 Typescript 开发的时候,很麻烦的一个问题就是类型定义.导致在编译的时候,经常会看到一连串的找不到类型的提示.解决的方式经过了许多的变化,从 DefinitelyTyped 到 typings.最后是 @types.在 Typescript 2.0 之后,推荐使用 @types 方式. DefinitelyTyped 这个工具已经不被推荐,仅作介绍. 多数来自 javascript 的库是没有 TypeScript 类

作为iOS开发者,估计有很多都遇到过APP提交到App Store被拒,然后这些被拒的原因多种多样,今天dApps收集了常见的被拒的原因,以便更多开发者了解. 1.程序有重大bug,程序不能启动,或者中途退出.2.绕过苹果的付费渠道,我们之前游戏里的用兑换码兑换金币.3.游戏里有实物奖励的话,一定要说清楚,奖励由本公司负责,和苹果没有关系.4.用到苹果的标志.(应用的设计和Apple的Logo风格太像了也会被拒)5.网络功能不能正常访问.6.图标不能点击,不能点击的图标要置灰,或者直接隐藏.7.

苹果官方发布的十大常见被拒原因 1.崩溃次数和Bug数量.苹果要求开发者在将应用提交给App Store之前彻查自己的应用,以尽量避免Bug的存在. 2.链或错误的链接.应用中所有的链接必须是真实且有效的. 3.占位符内容.有占位符内容的应用将无法审核通过. 4.提交的信息不完整.苹果要求开发者提供所有必须在iTunes Connect的应用审查信息区(App Review Information Section)中提交审查时所需要用到的所有完整信息.这是应用审核未通过最常见的原因,占到了14%

在我们进入章节之前,我们讨论一下生成.打包和部署你的应用程序和应用程序类型必须的步骤.在这章里,我关注的是如何为你的应用程序的用途生成程序集.在第三章,"共享程序集合和强命名程序集",我会涉及你需要了解的高级概念,包括如何生成和使用包含类型的程序集,这些程序集将被多个应用程序共享.在这两章中,我也会讨论管理员可以影响执行应用程序和它的类型的方式. 如今,应用程序由几个类型组成,通常由你和微软创建.此外,有很多组件供应商创建和出售类型,其它公司购买可以减少软件项目开发时间.假如这些类型是
