i tried smiless's code. keyboard disappear gradually when view appears. there way remove slow motion disappearing?

- (void)viewdidappear:(bool)animated { [super viewdidappear:animated]; [self.view endediting:yes]; }

try 1 dismiss keyboard when user taps somewhere else :

- (void)touchesbegan:(nsset *)touches withevent:(uievent *)event{ [self.view endediting:yes]; }
