用于推送与模态segue的用例？ [英] Use case for push versus modal segues?
问题描述
假设我有一个场景（带有导航栏的推视控制器），它在表格视图中显示一些表格数据。
在那个场景的导航栏中，我有一个+号，它应该打开一个新场景，用户可以在其中添加一个新项目（行到核心数据表）。
在表格视图中，每行在每个单元格的右侧都有一个箭头，这会打开一个场景，用户可以在其中编辑该特定项目的详细信息。
我应该使用push或modal segue作为+吗？
我应该使用推动或模态segue箭头吗？
什么是最佳做法？
我理解push和modal segues之间的区别，但我想知道哪种更适合上述用例。
Let's say, I have a scene (pushed view controller with a navigation bar), which displays some tabular data in a table view. In the navigation bar of that scene I have a + sign, which should open a new scene, where the user can add a new item (row to a core data table). In the table view, each row has an arrow on the right side of each cell, which opens a scene where the user can edit that particular item's details. Should I use a push or modal segue for the +? Should I use a push or modal segue for the arrow? What is the "best practise"? I understand the difference between push and modal segues, but I want to know which is better suited for the above use cases.
推荐答案
如果您想遵循Apple的最佳做法，我建议如下：
If you want to follow Apple's best practices, I would suggest the following :
-
对于添加功能，请使用模态 segue。
例如，查看联系人应用。按+显示模态视图控制器。
逻辑是什么？开始时，模态视图控制器通常有一个取消按钮，而不是按下推动的vc上的后退按钮。
当用户按下后退时 - 他希望有一种方法可以来回到vc。通常返回会将您的数据保存在iOS上（自动保存）。
因此，通过使用模态segue，您可以强制用户提交表单，或取消。模态演示提示您确实需要填写此屏幕。
For the "Add" functionality, use a modal segue.
For example look at the contacts app. Pressing + shows a modal view controller.
What's the logic ? for start, modal view controllers usually have a "cancel" button, as opposed to the "back" button on a pushed vc.
When the user presses "back" - he'd expect a way to come back to the vc. Usually "back" saves your data on iOS (auto-saved).
So by using a modal segue you force the user to submit the form , or cancel. The modal presentation hints that you really need to fill this screen.
进行编辑 - 推送。但模态也可以工作（你可以重复使用相同的VC）。
推送的理由：
For editing - push. but modal could work as well (and you could reuse the same VC).
Reasons for push :
- 你获取vc的层次结构，在向下钻取时前后移动。
- （你应该实现）返回时自动保存（就像其他iOS应用程序一样）
