問題：
I was going through the release notes for Xcode 4.4 and noticed this:我正在瀏覽 Xcode 4.4 的發行說明並注意到這一點：
LLVM 4.0 Compiler LLVM 4.0 編譯器
Xcode now includes the Apple LLVM Compiler version 4.0, including the following newObjective-C language features: [...] Xcode 現在包含 Apple LLVM 編譯器 4.0 版，包括以下新的Objective-C 語言特性：[...]
- Objective-C literals: create literals for NSArray, NSDictionary, and NSNumber, just the same as the literals for NSString - Objective-C 文字：爲 NSArray、NSDictionary 和 NSNumber 創建文字，與 NSString 的文字相同
I'm intrigued about this feature.我對這個功能很感興趣。 It's not entirely clear to me just how literals for NSString work and how one could use them on NSArray , NSDictionary , and NSNumber .我並不完全清楚NSString文字是如何工作的，以及如何在NSArray 、 NSDictionary和NSNumber上使用它們。
What are the details?詳情是什麼？
