ios - Have keyboard already presented on view on viewDidAppear? -

-

i have uipageviewcontroller initialized 3 controllers. when swipe right, presenting uiview has uitextview becomes firstresponder. trying achieve have keyboard appearing when user swipes right, , when swipe away hide keyboard within view. seems keyboard added onto window? facebook seems achieve when posting new post, keyboard seems loaded before view appears?

i able keyboard show without animating keyboard when becomefirstresponder invoked on uitextview. there seems delay on when keyboard appears.

self.composeview.bodytextview.inputaccessoryview = [uiview new]; [[nsnotificationcenter defaultcenter] addobserver:self                                          selector:@selector(willshowkeyboard:)                                              name:uikeyboardwillshownotification                                            object:nil];  [[nsnotificationcenter defaultcenter] addobserver:self                                          selector:@selector(didshowkeyboard:)                                              name:uikeyboarddidshownotification                                            object:nil];

it seem show view controller , pop keyboard @ same time cause delay.
suggestion let keyboard show little later. can either put [textview becomefirstresponder] in viewdidappear: or subclassing uitextfield override didmovetosuperview (put [self becomefirstresponder] on it).
