ios - Override Double Tap to Zoom in MKMapView -

is possible replace gesture in ios 6 custom gesture? have gesture show map in full screen hiding status , navigation bars , works zooms every time done.

here how have gesture implemented.

- (bool)gesturerecognizer:(uigesturerecognizer *)gesturerecognizer shouldrecognizesimultaneouslywithgesturerecognizer:(uigesturerecognizer *)othergesturerecognizer {     return yes; } 

in viewdidload:

uitapgesturerecognizer *tap = [[uitapgesturerecognizer alloc]initwithtarget:self action:@selector(togglebars:)];     tap.numberoftapsrequired = 2;     [self.view addgesturerecognizer:tap];     tap.delegate = self; 

gesture method:

- (void)togglebars:(uitapgesturerecognizer *)gesture {     bool barshidden = self.navigationcontroller.navigationbar.hidden;      if (!barshidden)     {         [[uiapplication sharedapplication] setstatusbarhidden:yes withanimation:uistatusbaranimationslide];         [self hidetabbar:self.tabbarcontroller];     }     else if (barshidden)     {         [[uiapplication sharedapplication] setstatusbarhidden:no withanimation:uistatusbaranimationslide];         [self showtabbar:self.tabbarcontroller];     }      [self.navigationcontroller setnavigationbarhidden:!barshidden animated:yes]; } 

methods hiding/showing tab bar:

- (void) hidetabbar:(uitabbarcontroller *) tabbarcontroller {     cgrect screenrect = [[uiscreen mainscreen] bounds];      [uiview beginanimations:nil context:null];     [uiview setanimationduration:0.5];     float fheight = screenrect.size.height;     if(  uideviceorientationislandscape([uiapplication sharedapplication].statusbarorientation) )     {         fheight = screenrect.size.width;     }      for(uiview *view in tabbarcontroller.view.subviews)     {         if([view iskindofclass:[uitabbar class]])         {             [view setframe:cgrectmake(view.frame.origin.x, fheight, view.frame.size.width, view.frame.size.height)];         }         else         {             [view setframe:cgrectmake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fheight)];             view.backgroundcolor = [uicolor blackcolor];         }     }     [uiview commitanimations]; }  - (void) showtabbar:(uitabbarcontroller *) tabbarcontroller {     cgrect screenrect = [[uiscreen mainscreen] bounds];     float fheight = screenrect.size.height - 49.0;      if(  uideviceorientationislandscape([uiapplication sharedapplication].statusbarorientation) )     {         fheight = screenrect.size.width - 49.0;     }      [uiview beginanimations:nil context:null];     [uiview setanimationduration:0.5];     for(uiview *view in tabbarcontroller.view.subviews)     {         if([view iskindofclass:[uitabbar class]])         {             [view setframe:cgrectmake(view.frame.origin.x, fheight, view.frame.size.width, view.frame.size.height)];         }         else         {             [view setframe:cgrectmake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fheight)];         }     }     [uiview commitanimations]; }
