[英]Do I have to retain an object before passing it to -performSelector:withObject:afterDelay:?
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。 我把这个数组传递给了
- (void)performSelector:(SEL)aSelector withObject:(id)anArgument afterDelay:(NSTimeInterval)delay
方法。 之后，我不再需要调用此performSelector的方法中的数组：withObject：afterDelay：。
该文档没有说明是否会保留anArgument，所以我想知道我是否必须自动发布或保留它才能保持活力。 你怎么看？
performSelector方法保留其接收者和参数。
