Scenario Description:
To implement interface A in Tableviewcontroller, click on a cell and jump to the second Viewcontroller interface B. In the second interface, do the corresponding operation.
In my practice, using SB, add a static table in a, and hold down CTRL to make the cell-to-B controller connection. Give Segue a identifier: "Mysegue".
Run, found that the B interface will pop up two times.
The correct approach, when connecting, is to connect from the a controller to the B controller, not from the cell.
Viewload do not overload easily. Reason:
2, Loadview
Creating your View objects
Only the view is initialized, typically used to create a more critical view such as Tableviewcontroller's Tabview,uinavigationcontroller Navgationbar, Do not swap out the view getter (before you drop the Super Loadview), it is best not to initialize some non-critical view. If you are creating a Viewcontroller from the nib file, you must first call Super's Loadview method, but it is not recommended to overload this method.
