UI-UISEARCHCONTROLLER&UISEARCHDISPLAYCONTROLLER__ Search

Brief Introduction

System with the Search page class-uisearchdisplaycontroller and Uisearchcontroller detailed use of the method, so that you more convenient and efficient search function development. The effect is as follows:
Uisearchdisplaycontroller

Ns_class_deprecated_ios (3_0, 8_0, "Uisearchdisplaycontroller has been replaced with Uisearchcontroller") 1. Take a look at the attributes and agents that are used first

return Dataarr; }

2. Create TableView and Uisearchdisplaycontroller for the current page

-(void) Configuretableview
{
    Self.dataarr = [self create createdata];
    Self.tableview = [[UITableView alloc]initwithframe:cgrectmake (0, 375, m) Style:uitableviewstyleplain];
    _tableview.delegate = self;
    _tableview.datasource = self;
    [Self.view Addsubview:_tableview];
    [Self Configuretableview:_tableview];
}

-(void) Addsearchbarandsearchdisplaycontroller
{
    Uisearchbar *searchbar = [[Uisearchbar alloc] init];
    [Searchbar SizeToFit];
    Searchbar.delegate = self;
    Self.tableView.tableHeaderView = Searchbar;

    Self.searchdisplaycontroller = [[Uisearchdisplaycontroller alloc] Initwithsearchbar:searchbar contentsController: Self];
    _searchdisplaycontroller.delegate = self;
    _searchdisplaycontroller.searchresultsdatasource = self;
    _searchdisplaycontroller.searchresultsdelegate = self;
}

3. Tableviewdatasource and Tableviewdelegate

Uisearchcontroller

In the Uisearchcontroller example, a separate controller is passed in, and the Uisearchdisplaycontroller example is a tableview in the current controller.
