使用alloc init代替new [英] Use of alloc init instead of new

问题描述

学习Objective-C并阅读示例代码，我注意到对象通常是使用这种方法创建的:

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];

这是有原因的吗，因为我已经知道它们是等效的?

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

一些选定的是:

• new不支持自定义初始化程序(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

一般认为，您应该使用自己喜欢的任何东西.

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