为什么Objective-C在Apple社区之外不那么受欢迎? [英] Why is Objective-C not very popular outside of the Apple community?
问题描述
我知道，包括Mac和iPhone开发人员在内的Apple社区主要使用Objective-C作为其开发语言.但是，似乎没有多少人在Apple社区之外使用Objective-C，例如在Windows或Linux世界中.
I know that the Apple community – including Mac and iPhone developers – mainly use Objective-C for their development language. But it seems that not many people use Objective-C outside of the Apple community, such as in the Windows or Linux worlds.
Objective-C在苹果社区之外不受欢迎的可能原因是什么?
What are the possible reasons that Objective-C is not particularly popular outside of the Apple community?
推荐答案
对此问题的另一种思考方式可能是:为什么C ++而不是Objective-C成为面向对象的C"?
Another way of thinking about this question might be: why did C++, rather than Objective-C, become the "Object-Oriented C"?
我在1991年学习C ++，并记得C ++似乎很热门，而Objective-C是一种奇怪的小语言，没有人(NeXT除外)想要使用.我一直想着记住原因，并且我认为它可以归结为4件事(如果包含C ++并带有AT& T，则可以归结为5):
I learned C++ in 1991, and remember that C++ seemed like the hot thing while Objective-C was this weird little language that no-one (other than NeXT) wanted to use. I've been trying to remember why, and I think it boils down to 4 things (5, if you include C++ having AT&T behind it):
- 功能:即使到那时，C ++的功能也比Objective-C丰富得多.
- 语法:与C ++相比，Objective-C的语法从C的变化要大得多.
- 性能:Stroustrup致力于使C ++功能易于映射到C，因此(理论上！)使用C ++不会造成性能损失.而且，通过明智地使用"inline"关键字，与C相比，C ++可以获得更好的性能.即使到现在，我也无法在对性能至关重要的项目中使用Objective-C.
- 样式:相对强而静态的打字是一种时尚(有充分的理由).
因此，与Objective-C相比，90年代初期的C ++为您提供了更多功能，而对性能的影响却更少，并且语法比Objective-C更为时尚和更加熟悉.
So compared to Objective-C, C++ in the early '90s gave you more features with less of a performance penalty, with a syntax that was both fashionable and more familiar than Objective-C's.
