Trailing switch of ios_20_ Weibo dock

Finally: Dock trailing HOMEVC switch together

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 the controller on the left side returns Button,dock also comes 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 you can see,

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

1, the upper navigation controller 2, the following dock

The view of the upper navigation Controller also contains 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 be able to slide past together, and can slide back together,

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

so that it can listen to the push action Willshowviewcontroller and Didshowviewcontroller methods

In the following Willshowviewcontroller methods,

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

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.

This is achieved, let the main controller inside the dock trailing navigation controller root controller, together disappear, and back together ~
