使用 alloc init 而不是 new [英] Use of alloc init instead of new

问题描述

学习Objective-C并阅读示例代码，我注意到通常使用这种方法创建对象:

Learning Objective-C and reading sample code, I notice that objects are usually created using this method:

SomeObject *myObject = [[SomeObject alloc] init];

代替:

SomeObject *myObject = [SomeObject new];

这是否有原因，因为我已经读到它们是等效的?

Is there a reason for this, as I have read that they are equivalent?

推荐答案

这里有很多原因:http://macresearch.org/difference-between-alloc-init-and-new

部分选定的是:

• new 不支持自定义初始值设定项(例如 initWithString)
• alloc-init 比 new
更明确

• new doesn't support custom initializers (like initWithString)
• alloc-init is more explicit than new

一般的意见似乎是你应该使用任何你觉得舒服的东西.

General opinion seems to be that you should use whatever you're comfortable with.
