IOS Swift&oc emulate mainstream app for sliding view hidden navigation bar

Simple directly on the code-.-a GIF figure 5M?

@property (nonatomicstrongUITableView *tableViewScroll;@property (nonatomicassigndouble//记录滑动的距离@property (nonatomicstrongUIView *customView;@property (nonatomicstrongUIButton *btn;

Create the desired view

-(uitableview  *)        tableviewscroll{if  (_tableviewscroll = = nil ) { _tableviewscroll = [[uitableview  alloc] Initwithframe:cgrectmake (0 , 0 , ScreenWidth, ScreenHeight) Style:uitableviewstyleplain]        ;        _tableviewscroll.delegate  = self ;        _tableviewscroll.datasource  = self ; [_tableviewscroll registerclass:[uitableviewcell  class] Forcellreuseidentifier    : Cellidentifier]; } return  _tableviewscroll;}  

-(uiview  *) customview{if  (_customview = = nil ) {_custo MView = [[uiview  alloc] Initwithframe:cgrectmake (0        , 44 , ScreenWidth, 30 )]; _customview.backgroundcolor  = [UIColor     Lightgraycolor]; } return  _customview;}  

-(uibutton  *) btn{ If  (_btn = = nil ) {_btn = [uibutton  but Tonwithtype:uibuttontypecustom]; _btn.frame  = CGRectMake (ScreenWidth-70 , 5 , 40 , 20 ); [_btn settitle:@ "attention"  forstate:uicontrolstatenormal]; _btn.titlelabel  .font  = [uifont  systemfontofsize:13 ]; _btn.backgroundcolor  = [uicolor  GreenColor] ; } return  _btn;} 

The key is the processing in the ScrollView protocol method

//objective-c -( void ) Scrollviewdidenddecelerating: (uiscrollview  *) scrollview{//record sliding distance  self   = Scrollview.contentoffset  ; nslog  (@ "histroy_y ========%lf" , self  .recorddistance );} //Swift  func scrollviewdidenddecelerating (scrollView: uiscrollview ) {self  .recorddistance  = Scrollview.contentoffset  .y } 

//Objective-c- (void) Scrollviewdidscroll: (Uiscrollview*) scrollview{NSLog(@"y =======%lf", ScrollView. Contentoffset. Y); ScrollView. Contentoffset. Y> Self. Recorddistance? ScrollView. Contentoffset. Y< Self. Recorddistance? [ Self. NavigationcontrollerSetnavigationbarhidden:NOAnimated:YES]:[ Self. NavigationcontrollerSetnavigationbarhidden:YESAnimated:YES] : [ Self. NavigationcontrollerSetnavigationbarhidden:NOAnimated:YES];}//SwiftFunc Scrollviewdidscroll (ScrollView:Uiscrollview) {ScrollView. Contentoffset. Y> Self. Recorddistance? ScrollView. Contentoffset. Y< Self. Recorddistance? Self. Navigationcontroller?. Setnavigationbarhidden(false, Animated:true): Self. Navigationcontroller?. Setnavigationbarhidden(true, Animated:true) : Self. Navigationcontroller?. Setnavigationbarhidden(false, Animated:true); }

Omitted TableView-related code
in Viewdidload

 [Self.view     Addsubview:self.tableviewscroll ] [Self.navigationcontroller   addsubview:self.customview ]     [Self.customview  addsubview:self.btn    ] Self.title  = @ "This is a test page"   Self.navigationcontroller  .navigationBar  .bartintcolor  = [Uicolor lightgraycolor] ;

I think I can have a good, I want to apply for micro Boga v. Just a little Sir-.-hahaha.
