Source code Address: Https://github.com/JxbSir/YiYuanYunGou

The effect is as follows:

1: In the main page first define the key and bound view (not written in the attribute is defined such as Btnrigth,dropdownview, etc.):

Btnrigth = [UIButton buttonwithtype:uibuttontypecustom];    [Btnrigth addtarget:self Action: @selector (Btnrightaction) forcontrolevents:uicontroleventtouchupinside];    if (![ Oytool Shardinstance].bisforreview)    {        [self actioncustomnavbtn:btnrigth nrlimage:@ "" htlimage:@ "" title:@ " All categories "];    }    else    {        [self actioncustomnavbtn:btnrigth nrlimage:@ "" htlimage:@ "" title:[dictypename.allvalues OBJECTATINDEX:0]];    }    Self.navigationItem.rightBarButtonItem = [[Uibarbuttonitem alloc] initwithcustomview:btnrigth];    allprotypeview* Tview = [[Allprotypeview alloc] initWithFrame:self.view.bounds];    Tview.delegate = self;    In the drop-down effect view    dropdownview = [[Lmdropdownview alloc] init];    Dropdownview.menubackgroundcolor = [Uicolor whitecolor];    Dropdownview.menucontentview = Tview;

2: Where to set the key to the package:

-(void) ACTIONCUSTOMNAVBTN: (UIButton *) btn nrlimage: (NSString *) nrlimage                  htlimage: (NSString *) Hltimage                     Title: (NSString *) title {    [btn setimage:[uiimage imagenamed:nrlimage] forstate:uicontrolstatenormal];    if (hltimage) {        [btn setimage:[uiimage imagenamed:hltimage] forstate:uicontrolstatehighlighted];    } else {        [btn setimage:[uiimage imagenamed:nrlimage] forstate:uicontrolstatenormal];    }    if (title) {        Btn.titleLabel.font = [Uifont boldsystemfontofsize:13];        [Btn Settitle:title forstate:uicontrolstatenormal];        [Btn Settitle:title forstate:uicontrolstatehighlighted];        [btn Settitlecolor:[uicolor Whitecolor] forstate:uicontrolstatenormal];        [btn Settitlecolor:[uicolor Whitecolor] forstate:uicontrolstatehighlighted];    }    [Btn SizeToFit];}

3: Where Btnrightaction responds to event content (primarily for display and hide drop-down effects):

-(void) btnrightaction{    if ([Dropdownview IsOpen])    {        [dropdownview hide];    }    else    {        //[tbviewtype reloaddata];        [Dropdownview ShowInView:self.view withframe:cgrectmake (0, 0, Mainwidth, self.view.bounds.size.height)];}    }

The view code for the 4:allprotypeview drop-down content is as follows (is a list):

. h file Contents #import <UIKit/UIKit.h> @protocol allprotypeviewdelegate-(void) Selectedtypecode: (int) code;@ End@interface Allprotypeview:uiview@property (nonatomic,weak) id<allprotypeviewdelegate> delegate; @end. m File contents        @interface Allprotypeview () <uitableviewdatasource,uitableviewdelegate>{UITableView *tbView;    Nsarray *arroftype;    Nsarray *arroftypeimage;        Nsinteger Indextype; __weak id<allprotypeviewdelegate> Delegate;} @end @implementation allprotypeview@synthesize delegate;-(ID) initWithFrame: (cgrect) frame{self = [Super InitWithFrame    : frame];                if (self) {self.backgroundcolor = [uicolor Redcolor]; Tbview = [[UITableView alloc] Initwithframe:cgrectmake (0, 0, mainwidth, frame.size.height) style:        Uitableviewstylegrouped];        Tbview.delegate = self;        Tbview.datasource = self;        Tbview.backgroundcolor = [Uicolor Whitecolor]; Tbview.separatorstyle = UitableviewcellseparatorstylesingleLine; Tbview.autoresizingmask = Uiviewautoresizingflexiblewidth |        Uiviewautoresizingflexibleheight;                [Self addsubview:tbview]; if (![ Oytool shardinstance].bisforreview) {Arroftype = @[@ "All categories" @ "mobile phone digital" @ "PC Office" @ "Home appliances" @ "Makeup protection" @ "Watch jewellery" @ "other            Goods "];        Arroftypeimage = @[@ "Sort0", @ "sort100", @ "sort106", @ "sort104", @ "Sort2", @ "sort222", @ "sort312"];            } else {arroftype = @[@ "Home appliances" @ "makeup guard" @ "Watch jewellery" @ "other goods"];        Arroftypeimage = @[@ "sort104", @ "Sort2", @ "sort222", @ "sort312"]; }} return self;} #pragma mark-tableview-(Nsinteger) Numberofsectionsintableview: (UITableView *) tableview{return 1;} -(Nsinteger) TableView: (UITableView *) TableView numberofrowsinsection: (nsinteger) section{return arroftype.count;} -(CGFloat) TableView: (UITableView *) TableView Heightforrowatindexpath: (Nsindexpath *) indexpath{return 44;} -(CGFloat) TableView: (UITableView *) TableView heightforheaderinsection: (Nsinteger)section{return 0.1;} -(CGFloat) TableView: (UITableView *) TableView heightforfooterinsection: (Nsinteger) section{return 0.1;} -(uitableviewcell*) TableView: (UITableView *) TableView Cellforrowatindexpath: (Nsindexpath *) indexpath{//static    NSString *cellidentifier = @ "Cell";    UITableViewCell *cell = nil;//(uitableviewcell*) [TableView Dequeuereusablecellwithidentifier:cellidentifier];    if (cell = = nil) {cell = [[UITableViewCell alloc] init];    } cell.textLabel.text = [NSString stringwithformat:@ "%@", [Arroftype ObjectAtIndex:indexPath.row]];     nsstring* name = [Arroftypeimage ObjectAtIndex:indexPath.row];        if (Indexpath.row = = indextype) {name = [NSString stringwithformat:@ "%@_checked", name];                Cell.textLabel.textColor = Maincolor;        uiimageview* Imgok = [[Uiimageview alloc] Initwithframe:cgrectmake (mainWidth-32, 14, 20, 16)];        Imgok.image = [UIImage imagenamed:@ "Screening_select"]; [Cell Addsubview:imgok];   } else {name = [NSString stringwithformat:@ "%@_normal", name];    } uiimageview* img = [[Uiimageview alloc] Initwithframe:cgrectmake (16, 10, 24, 24)];    Img.image = [UIImage imagenamed:name];    [Cell addsubview:img]; return cell;} -(void) TableView: (UITableView *) TableView Didselectrowatindexpath: (Nsindexpath *) indexpath{[TableView    Deselectrowatindexpath:indexpath Animated:yes];    Indextype = Indexpath.row;        [Tbview Reloaddata]; if (delegate) {nsstring* code = [[Arroftypeimage ObjectAtIndex:indexPath.row] Stringbyreplacingoccurrencesofstri        ng:@ "Sort" withstring:@ "" ";    [Delegate Selectedtypecode:[code Intvalue]; }} @end

Note: The list has a binding is selected, it shows the effect is not the same, at the time of the release of the identifier is re-assigned to pass through delegate it back to the main view control device;

5: The main controller in response to the above delegate content is:

-(void) Selectedtypecode: (int) code{    icodetype = code;    [Dropdownview hide];        nsstring* key = [NSString stringwithformat:@ "%d", code];    nsstring* name = [Dictypename Objectforkey:key];        [Self actioncustomnavbtn:btnrigth nrlimage:@ "" htlimage:@ "0" title:name];       Rebind List display content    __weak typeof (self) wself = self;    Curpage = 1;    [Self getdata:^{        __strong typeof (wself) sself = wself;        Sself->listnew = nil;    }];}
