开发iPhone应用程序需要多少钱？ [英] How much does it cost to develop an iPhone application?

问题描述

开发者可以为 Twitterrific 等iPhone应用收取多少费用？

How much can a developer charge for an iPhone app like Twitterrific?

我想知道这一点，因为我需要这样一个具有相同功能的应用程序用于新的社区网站。我可以做Ruby，但没有使用Objective-C的经验。因此，如果我应该开始阅读有关iPhone编程的书籍或将工作外包给iPhone程序员，那对我来说会很有趣。

I want to know this because I need such an application with the same functionality for a new community website. I can do Ruby but have no experience with Objective-C. So it would be interesting for me if I should start reading books about iPhone programming or outsource the work to a iPhone programmer.

推荐答案

我是Twitterrific的开发人员之一，说实话，我不能告诉你已经进入产品的时间。我可以告诉大家，估计开发时间为160小时，设计时间为40小时的人数很高。 （我会使用另一个短语，但这是我在Stack Overflow上的第一篇文章，所以我很好。）

I'm one of the developers for Twitterrific and to be honest, I can't tell you how many hours have gone into the product. I can tell you everyone who upvoted the estimate of 160 hours for development and 40 hours for design is fricken' high. (I'd use another phrase, but this is my first post on Stack Overflow, so I'm being good.)

Twitterrific有4个主要版本，从iOS 1.0（Jailbreak。）这是很多代码，其中大部分代码都在位（我们对每个主要版本都进行了很多重构。）

Twitterrific has had 4 major releases beginning with the iOS 1.0 (Jailbreak.) That's a lot of code, much of which is in the bit bucket (we refactor a lot with each major release.)

有一件事情会有趣的是，我们必须在iPad版本上工作的时间量。 Apple设定了产品发布日期，为我们提供了60天的开发时间。 （后来延长了一周。）

One thing that would be interesting to look at is the amount of time that we had to work on the iPad version. Apple set a product release date that gave us 60 days to do the development. (That was later extended by a week.)

我们从头开始开发iPad，但很多底层代码（主要是模型）都被重用了。开发工作由两位经验丰富的iOS开发人员完成。其中一人甚至写了一本书： http://appdevmanual.com ： - ）

We started the iPad development from scratch, but a lot of our underlying code (mostly models) was re-used. The development was done by two experienced iOS developers. One of them has even written a book: http://appdevmanual.com :-)

如此短的时间表，我们工作了很长时间。让我们保守一点，说每周工作6天，每周工作10天。 9周的60小时给我们540小时。有两个开发人员，这非常接近1,100小时。我们的客户费率为每小时150美元，仅为新代码提供165,000美元。还要记住，我们正在重复使用现有代码：我将以35,000美元的价格降低该代码的价值，总开发成本为200,000美元。

With such a short schedule, we worked some pretty long hours. Let's be conservative and say it's 10 hours per day for 6 days a week. That 60 hours for 9 weeks gives us 540 hours. With two developers, that's pretty close to 1,100 hours. Our rate for clients is $150 per hour giving $165,000 just for new code. Remember also that we were reusing a bunch existing code: I'm going to lowball the value of that code at $35,000 giving a total development cost of $200,000.

任何完成的人严肃的iPhone开发可以告诉你，任何项目涉及很多设计工作。我们有两位设计师正在研究产品的这个方面。他们在处理完全新的交互机制时不再努力。不要忘记他们也没有任何硬件可以触摸（很多打印输出！）他们每周至少花25个小时在项目上。因此225小时150美元/小时约为34,000美元。

Anyone who's done serious iPhone development can tell you there's a lot of design work involved with any project. We had two designers working on that aspect of the product. They worked their asses off dealing with completely new interaction mechanics. Don't forget they didn't have any hardware to touch, either (LOTS of printouts!) Combined they spent at least 25 hours per week on the project. So 225 hours at $150/hr is about $34,000.

许多开发商还忽略了其他成本：项目管理，测试和设备。再说一次，如果我们将这个数字降低到16,000美元，我们将达到25万美元。这个数字与Jonathan Wight（@schwa）估计的22天奥巴马应用程序一致。

There are also other costs that many developer neglect to take into account: project management, testing, equipment. Again, if we lowball that figure at $16,000 we're at $250,000. This number falls in line with Jonathan Wight's (@schwa) $50-150K estimate with the 22 day Obama app.

再次点击，伙计。

现在，如果你想为你的应用程序构建后端服务，那么这个数字会更高。每个人都惊讶于Instagram通过风险投资掏出50万美元来建立一个新的前端和后端。我不是。

Now if you want to build backend services for your app, that number's going to go up even more. Everyone seems surprised that Instagram chewed through $500K in venture funding to build a new frontend and backend. I'm not.
