什么时候应该使用视图控制器的addSubview方法? [英] When should I use the addSubview method of a view controller?
问题描述
我正在为iPhone编程,我想知道什么时候使用视图的addSubview方法和何时提交使用模态视图控制器(presentModalViewController)。更复杂的是,如果你正在使用导航控制器(我不是),你可以使用pushViewController方法?
什么时候使用每个和为什么?
感谢。
-presentModalViewController
和 -pushViewController
是两种方法来处理同样的事情:显示一个新的视图。您使用哪一个取决于您要去的用户体验。它们对用户意味着不同的东西,但在实现上非常相似。
-addSubview
完全不同。它将组件添加到当前视图。您不应该使用它来显示独立的UI。 -addSubview
最常用于在 -loadView
中以编程方式创建UI时,尽管它还有许多其他用途。 p>
I'm programming for the iPhone and I'm wondering when to use the addSubview method of a view and when to present to use the modal view controller (presentModalViewController). What complicates this even more is if you are using a navigation controller (I'm not) and you can use the pushViewController method?
When would you use each and why?
Thanks.
-presentModalViewController
and -pushViewController
are two ways of going about the same thing: displaying a new view. Which you use depends on the user experience you're going for. They mean different things to the user, but are very similar in implementation.
-addSubview
is completely different. It adds components to the current view. You should never use it to display an independent UI. -addSubview
is most often used when programmatically creating the UI in -loadView
, though it has many other uses.
