我已经用 swift 编写了一堆代码并且更喜欢以编程方式编写很多代码，我想知道这两者之间的区别是什么:
self.view.addSubview(someNewView)
view.addSubview(someNewView)
它们似乎都有效。出于某种原因更好吗？它们真的那么不同吗？
如果这是一个愚蠢的问题或已经回答，可以将其删除。只是一个想法。
最佳答案
没有真正的区别，尽管您可能会更频繁地看到以前的 Objective-C 开发人员使用 self。来自文档:
In practice, you don’t need to write self in your code very often. If you don’t explicitly write self, Swift assumes that you are referring to a property or method of the current instance whenever you use a known property or method name within a method.
...
The main exception to this rule occurs when a parameter name for an instance method has the same name as a property of that instance. In this situation, the parameter name takes precedence, and it becomes necessary to refer to the property in a more qualified way.
关于ios - self.view.addSubview 和 view.addSubview 的区别，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27752535/
