1. Custom controller switch < one >

I. Custom controller switching: On the same controller, show different controllers, similar to Tabbar

Two. What do I do? (Problem resolution Steps)

1. Create several controllers: Oneviewcontroller Twoviewcontroller .....

2. Define a realistic controller:

Defined:

@property (nonatomic, weak) Uiviewcontroller *SHOWINGVC;

self.childviewcontrollers= @[

[[Zsoneviewcontroller alloc] init],

[[Zstwoviewcontroller alloc] init],

[[Zsthreeviewcontroller alloc] init]

];

Or

[Self Addchildviewcontroller:[[zsoneviewcontroller alloc] init]];

[Self Addchildviewcontroller:[[zstwoviewcontroller alloc] init]];

[Self Addchildviewcontroller:[[zsthreeviewcontroller alloc] init]];

3. Core steps: 3.1. Remove the view on the real controller and get to the controller to be displayed and assign to the displayed controller--Add the displayed controller to the host controller

Remove the view from other controllers

[Self.showingVc.view Removefromsuperview];

Where to get the Controller (index)

Nsuinteger index = [button.superview.subviews Indexofobject:button];

Add view for Controller

SELF.SHOWINGVC = Self.childviewcontrollers[index];

Self.showingVc.view.frame = CGRectMake (0, Self.view.frame.size.width, self.view.frame.size.height-64);

[Self.view AddSubview:self.showingVc.view];

Knowledge Point Supplement:

Remove the first controller from the childviewcontrollers array

[Self.childviewcontrollers[0] removefromparentviewcontroller];
