ios - When dismissing keyboard how do I keep my existing text fields in the same location? -

so have uiscrollview contains uitextfields , uilabels, , when user clicks inside uitextfield keyboard shows. need way allow user dismiss keyboard , try use swipe down gesture (as in messages). added gesture recognizer view in storyboard , added action header file. here method:

- (ibaction)swipekeyboarddown:(id)sender {     if(self.movetextfield)     {         [self.movetextfield resignfirstresponder];     }  } 

i have if there testing when user has clicked on first text field, , when try swipe down of text field , labels move bottom of screen. there need keep text fields , labels in place? using auto layout , created them in storyboard.

this how view looks before swiping keyboard down:

and how looks after swiping down:

thanks help, , if more info needed please ask , can provide more.

and after looking @ code keyboard did show , hide methods wondering if maybe doing wrong there:

this in viewdidload:

[[nsnotificationcenter defaultcenter] addobserver:self                                          selector:@selector(keyboarddidshow)                                              name:uikeyboardwillshownotification                                            object:nil]; [[nsnotificationcenter defaultcenter] addobserver:self                                          selector:@selector(keyboarddidhide)                                              name:uikeyboardwillhidenotification                                            object:nil]; 

and these selectors:

- (void)keyboarddidhide {     if(keyboardshown)     {         cgrect r = self.scrollview.frame;         r.size.height += 216;         self.scrollview.frame = r;          keyboardshown = no;     } }  - (void)keyboarddidshow {     if(!keyboardshown)     {         cgrect r = self.scrollview.frame;         self.scrollview.contentsize = self.scrollview.frame.size;         r.size.height -= 216;         self.scrollview.frame = r;          keyboardshown = yes;     } } 

you don't need gesture recognizer.

scrollviews have keyboarddismissmode property. set uiscrollviewkeyboarddismissmodeondrag or uiscrollviewkeyboarddismissmodeinteractive , set go.
