iphone - how to change the arrow direction of UIMenuController just before shown in an UIWebView -

i trying change arrow direction when appears not block top bar set application. here code used change direction:

uimenucontroller *menucontroller = [uimenucontroller sharedmenucontroller]; [menucontroller setarrowdirection:uimenucontrollerarrowup]; 

and here result, say, pretty stressful:

it appears same issue on iphone well.

can this? thanks

after days of researching, find way change arrow direction of menu controller in webview. first, please in view controller's viewdidload method.

[[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(menucontrollerwillshow:) name:uimenucontrollerwillshowmenunotification object:nil]; [[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(menucontrollerwillhide:) name:uimenucontrollerwillhidemenunotification object:nil]; 

then, add these 2 functions, arrow direction pointing up, in case menubar appear below text. (same way, can change uimenucontrollerarrowup; other direction if want menubar appear in other position)

-(void)menucontrollerwillshow:(nsnotification *)notification{     //remove show notification prevent     // "menucontrollerwillshow" function called multiple times     [[nsnotificationcenter defaultcenter]removeobserver:self name:uimenucontrollerwillshowmenunotification object:nil];      //hide original menu view     uimenucontroller* menucontroller = [uimenucontroller sharedmenucontroller];     cgpoint origin = menucontroller.menuframe.origin;     cgsize size = menucontroller.menuframe.size;     cgrect menuframe;     menuframe.origin = origin;     menuframe.size = size;     [menucontroller setmenuvisible:no animated:no];      //modify target rect , show again prevent glitchy appearance     menucontroller.arrowdirection = uimenucontrollerarrowup;     [menucontroller settargetrect:menuframe inview:self.view];     [menucontroller setmenuvisible:yes animated:yes];  }  -(void)menucontrollerwillhide:(nsnotification *)notification{     //re-register menucontrollerwillshow     [[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(menucontrollerwillshow:) name:uimenucontrollerwillshowmenunotification object:nil]; }
