开发杀手级iPhone应用程序的7大法则编辑本段回目录
也许你从未预料到iPhone可以像星火燎原般迅速收获大量人气，但事实就是如此，而且我们也已经无法忽视苹果App Store中的大量应用程序。
App Store中已有不少从好玩、独特、不寻常，非主流的各类应用，该应用商店每天都会有上百款新产品露面，而一般每款应用的平均寿命却不足一周，所以要制作一款具有突破性的iPhone应用实在是一个不小的挑战。
推出一款热销iPhone应用并非易事，甚至会让开发者大为伤神。虽然这个领域暂时没有任何开发杀手级iPhone应用的精确法则，但如果做到以下7点，至少可以创建一款近乎完美的iPhone应用。

1.创新性，尝试推出一些新颖的内容：你的iPhone应用具备这一特点吗？它是否有创意，与众不同？它是同类产品中的唯一吗？如果是，那么你的应用就很容易在App Store中获得足够的曝光率。
2.实用性：你的应用也许极具创意，而且超乎寻常地新颖，但如果不具备实用性，那也难免无人理会。所以最好要创建一款具有实用价值的应用，奇特的应用是很不错，但它们并不会带来多大意义。开发iPhone应用时最好遵循苹果人性化且具有持久实用性的特点。
3.易用性：这是创建手机应用的黄金法则，没有人会喜欢一款令人困惑或难以操作的应用程序。你的产品越是不好用，它被用户接受的概率就越低。
4.灵活的定价策略：在互联网领域，免费产品最有市场。但这并不是说你只能开发免费的杀手级应用，你可以将其标价于0.99至20美元之间，只是定价需要谨慎。免费应用总比标有价格的产品更易获得曝光度，所以你可以选择不同的定价策略，先推出一个免费的测试版本，如果情况对路，那就再推出付费版新应用。
5.足够的用户支持：及时追踪应用运行的表现情况。如果用户运行一些功能时遇到一些麻烦，就得调整这些功能，或者及时发布具体操作指南。
6.及时更新内容：开发完工后还需不断更新产品功能。重视聆听用户反馈，并依此添加新功能。那些之前错过你的应用发布信息的用户，有可能因为它的更新版本而下载这款应用。
7.勿忽视市场营销作用：这无疑是创建杀手级应用的必须法则。不可开发完一款应用后就任其自生自灭。你市场营销行动越多，就越有可能获得用户关注。不必推出大规模的市场营销活动，只需采纳实用型、侧重结果的营销策略即可。做到以上这几点，你就有希望看到胜利的曙光了。（本文为游戏邦/gamerboom.com编译，作者：IREM BRIGHT CHIMEZIE）
7 Rules to build Killer iPhone Apps
by IREM BRIGHT CHIMEZIE
Bet you never thought the iPhone would grow so alarmingly popular. But it has, and we cannot simply ignore it or the millions of applications that float in the apple app Store.
From funny to unique, unique to unusual and bizarre, diverse kinds of applications rule the app Store. Hundreds of more such are launched everyday. With the app Store growing bigger and bigger everyday, the lifetime of an ordinary app denigrates to less than a week. Making a breakthrough iPhone app is indeed a challenge all iphone application developers face.
To launch a top-selling iPhone app is no easy job and requires a lot of racking your brain. Though there is no exact science to build a killer iPhone app, you can launch a near-perfect top seller if you follow these 7 rules of the thumb:
1. Innovate. Try something novel. Does your iPhone app have the ?wow? factor? Is it innovative, out of the ordinary? Is it the only one in its kind? If yes, your app will definitely get due recognition in the App Store.
2. make it usable: Your apps can be extraordinarily creative and startlingly new. But users are going to keep it idle if it is not usable. Build an app which has utility value. Fancy apps are good, but they don’t get you anywhere. A usability specialist says that one should follow apple’s sterling virtue of ?intuitive and consistent usability? while building apps for the iPhone.
3. Keep it Simple: Keeping it simple is a golden rule in mobile application development. No one wants an app that confuses or complicates things for them. The more difficult you make your app for usage, the less recognition it is going to receive from users.
4. Pricing: Anything sells if given for free in the Internet world. This does not mean you need to give your killer app for free. You can price it anywhere between $0.99 to $20. But, act prudently. Your app will get more exposure when given for free than when launched with a price tag. Maybe you can try different strategies. You can give your beta version for free and put a price on newer versions.
5. Provide Support: Be responsive to how your app performs in the store. If users are having difficulty in handling some feature, try to change it or post guides on how to handle your app.
6. Upgrades: Anything left idle grows stale. Never leave your app in beta. Keep upgrading new features. Listen to your users and add as many new features as possible. People who failed notice your app during its launch may notice its upgraded version and start using it.
7. marketing is must: Yes, without doubt, this is important in killer-app making. You cannot create a killer app if you fail to market it. The more your app is marketed, the more it gets noticed by users. Instead of aggressive marketing, engage in useful, result-oriented marketing. You’ll definitely hit the road to success.（source:appscreationguidecom）
