objective c - Making the UINavigationBar Disappear and Appear on a touch, mimicking safari on iOS -

i have uipageviewcontroller called uitableviewcontroller , shows series of images user.

the images contain lot of information , while doesn't make sense have uinavigationbar entire time, because it's used share image, or go back, there way mimic safari on ios, uinavigationbar @ top disappears , reappears on touch?

i have not tried because don't have first clue on start this. there third-party open source framework, or easy way animate this? perhaps in viewdidload, have timer on uinavigationbar, show @ start , disappear after 2 seconds, etc, reappear on touch?

any guidance on appreciated.

ios 8 provide default feature

self.navigationcontroller.hidesbarsontap = true; 

[edited] add tap gesture in viewdidload

uitapgesturerecognizer *taprecognizer = [[uitapgesturerecognizer alloc] initwithtarget:self action:@selector(taphandle:)]; [self.view addgesturerecognizer:taprecognizer]; 

add following method viewcontroller

- (void)taphandle:(uitapgesturerecognizer*)sender {      dispatch_after(dispatch_time(dispatch_time_now, 2 * nsec_per_sec), dispatch_get_main_queue(), ^{         if (self.navigationcontroller.navigationbarhidden == no) {                 [[self navigationcontroller] setnavigationbarhidden:yes animated:yes];         }         else{                 [[self navigationcontroller] setnavigationbarhidden:no animated:yes];         }     }); }
