iOS UITableView Search

Self-implementation UITableView search, compared to the use of Uisearchdisplaycontroller to write a little trouble for themselves a little bit, but more flexible. The main is to use a field to distinguish between the current search or non-search, and then reload the corresponding data on the line, and the implementation of Uisearchdisplaycontroller is similar, but Uisearchdisplaycontroller is two TableView switch, here we are a tableview load different data.

Key code:

@interface Maintableviewcontroller:uiviewcontroller<uisearchbardelegate,uitableviewdelegate,uitableviewdatasource> {    *mytableview;     *data;     *filterdata;     // identifies whether a search    is in progress UIView *mask;}

- (void) viewdidload{[Super Viewdidload]; Mytableview= [[UITableView alloc] Initwithframe:cgrectmake (0, -, Self.view.frame.size.width, self.view.frame.size.height- -)]; Mytableview.datasource=Self ; Mytableview.Delegate=Self ;        [Self.view Addsubview:mytableview]; Uisearchbar*searchbar = [[Uisearchbar alloc] Initwithframe:cgrectmake (0,0, Self.view.frame.size.width, -)]; Searchbar.placeholder=@"Search"; Searchbar.Delegate=Self ; Mytableview.tableheaderview=Searchbar; //Add a maskmask = [[UIView alloc] Initwithframe:cgrectmake (0, -+ -, Self.view.frame.size.width, Self.view.frame.size.height- -- -)];    [Self.view Addsubview:mask]; Mask.backgroundcolor=[Uicolor Blackcolor]; Mask.alpha=0;}
