这取决于您将如何使用该视图。如果将从方法返回的视图分配给某个对象（例如 UIViewController）并且该对象保留它，那么您应该在上述函数中自动释放该视图。这样，您将确保它在方法循环结束后自动释放，并且它的活动时间足以让对象保留它。所以代码将是这样的：
例如：
It depends on how you're going to use the view. If you assign the view returned from the method to some object (for example to a UIViewController) and that object retains it then you should autorelese the view in the above function. This way you'll make sure that it gets released automatically after the method loop ends and also it'll be alive long enough for an object to retain it. So the code will be like this:
For ex:
将其作为自动释放返回。使用此功能的人将负责其所有权。 查看此内容发布。
return it as auto-release. The one who uses this functions will take care of its ownership. See this post.
