Ios_20_ Weibo dock Follow-up switch

Final: Dock follows HOMEVC to switch

Requirements:

When you click on a line in the microblog list in Homevc,

Push to Statusdetail Weibo details controller, and the dock disappears together

When you click Statusdetail Weibo details controller The left back button on the top, and the dock is back with HOMEVC .

Homevc.m

Click on a microblog in the list to create a statusdetailviewcontroller, assign a value to its member status (data source), and enter the stack by navigation push-(void) TableView: (UITableView *) TableView Didselectrowatindexpath: (Nsindexpath *) indexpath{    //Create a microblog body detail controller,    Statusdetailviewcontroller * DETAILVC = [[Statusdetailviewcontroller alloc] init];    Transfer Weibo data (for display) for the microblog body controller that is about to jump    statuslistcellframe *statuslistcellframe = _statuscellframes[indexpath.row] ;    Detailvc.status = Statuslistcellframe.status;    Jump past through the navigation controller    [Self.navigationcontroller PUSHVIEWCONTROLLER:DETAILVC animated:yes];}

As shown,

The view of the host controller (BEYONDVC) contains two parts:

1, upper navigation controller 2, dock below

The view of the upper navigation controller also includes two sections:

1, the upper navigation bar (when push, it always does not move)

2, lower root controller (HOMEVC) (animation toggle when push)

In order for the dock and navigation controller root control (HOMEVC) to slip together and slide back together,

The host controller (BEYONDVC) must be the proxy for the navigation controller,

enable it to monitor the push action Willshowviewcontroller and Didshowviewcontroller methods

In the following Willshowviewcontroller method,

First remove the dock from the host controller (BEYONDVC) and add it to the navigation controller's root control (HOMEVC)

the proxy method for the navigation controller Willshowviewcontroller

in the following in the Didshowviewcontroller method,

First remove the dock from the navigation controller's root control (HOMEVC) and add it to the host controller (BEYONDVC)

the proxy method for the navigation controller Didshowviewcontroller

y = 20 of the navigation controller, height of the navigation controller = total Height-Dock height-20#define kcontentframe cgrectmake (0, Self.view.frame.size.width, Self.view . frame.size.height-kdockheight-20)//BEYONDVC host Controller, the dock y = total height-Dock Height # define Kdockframe cgrectmake (0, Self.view.fra Me.size.height-kdockheight, Self.view.frame.size.width, kdockheight)//The purpose is to monitor the push action and remove the dock from the navigation controller when the new controller is already displayed. And then re-display to the host controller-(void) Navigationcontroller: (Uinavigationcontroller *) Navigationcontroller Didshowviewcontroller: ( Uiviewcontroller *) Viewcontroller animated: (BOOL) animated{//The root controller of the bottom of the navigation first Uiviewcontroller *ROOTVC = Navigationco    Ntroller.viewcontrollers[0];   If the controller to be displayed is the root controller, re-place the dock if (Viewcontroller = = ROOTVC) {//Change the navigation controller view's frame//navigation Controller's y = 20, the height of the navigation controller =                Total height-dock height-navigationController.view.frame = kcontentframe;                Remove the dock first from the root controller ROOTVC on the bottom of the stack [_dock Removefromsuperview]; Add the dock to beyondviewcontroller,dock y = total height-Dock height _dock.frame = kdockframe;       [Self.view Addsubview:_dock]; }}

This allows the dock in the main controller to follow the root controller of the navigation controller, disappear together, and come back together .
