Modal view returns the method for the previous view: [Self dismissviewcontrolleranimated:yes completion:nil]; The first parameter is whether the table uses a toggle animation effect, and a block of code on the second parameter table.

Uinavigationcontroller in the Stack method: [Self.navigationcontroller pushviewcontroller:<# (Uiviewcontroller *) #> animated:<# (BOOL) #>]; the first parameter table to switch to the view that is pressed into the stack, the second parameter indicates whether there is a toggle animation effect.
