# 私が考える安全なプログラムを書くために必要なこと

今も昔も「入力によって挙動が大幅に変わるAPI」が世の中には多数存在していて、プログラマが本来意図した挙動と異なる動作を引き起こしている。

- ファイルを開こうとしたらコマンドを実行できてしまったり
- CSSセレクタを書いてるつもりがHTMLタグを生成してしまったり
- SELECT文を発行するつもりがDELETE文を発行できてしまったり

こういったときに
- 入力値検証をしないと危険になる

Greetings, NSHipsters!

As we prepare to increment our NSDateComponents -year by 1, it's time once again for NSHipster end-of-the-year Reader Submissions! Last year, we got some mind-blowing tips and tricks. With the release of iOS 7 & Mavericks, and a year's worth of new developments in the Objective-C ecosystem, there should be a ton of new stuff to write up for this year.

Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

Here are a few examples of the kind of things I'd like to see:

• Using NSStringFromSelector(@selector()) as a safer way to do KVC / KVO / NSCoding.
• Panic's [rather surprising discovery about the internals of the Lightning Digital AV Adapter](http://www.panic.com/blog/the-lightning-di

  // add back button to navigation bar

  self.navigationItem.leftBarButtonItem = backItem;

こういうハッシュでエラーが出ます。どうしたら良いでしょうか!?
