问题描述

我正在一个方法中创建一个NSArray,所以当我完成它时,我必须放弃它。我将此数组传递给

I am creating an NSArray inside a method, so I have to give it up with release when I'm done with it. I pass this array to the

- (void)performSelector:(SEL)aSelector withObject:(id)anArgument afterDelay:(NSTimeInterval)delay

方法。在那之后,我不再需要在调用这个performSelector的方法中使用数组:withObject:afterDelay:。

method. After that, I don't need the array anymore in my method that calls this performSelector:withObject:afterDelay:.

该文档没有说明anArgument是否会保留,所以我想知道我是否必须自动发布或保留它以保持活力。您怎么看?

The documentaton doesn't say if anArgument is going to be retained, so I wonder if I had to autorelease it or retain it in order to stay alive. What do you think?

推荐答案

方法保留他们的接收器和参数。

The performSelector methods retain their receiver and argument.
