View doesn't move up when keyboard is present iOS - ios

Question

I am trying to use this code
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
NSLog(#"%f",self.view.frame.origin.y);
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.25f];
CGRect frame = self.view.frame;
frame.origin.y =frame.origin.y -204;
[self.view setFrame:frame];
[UIView commitAnimations];
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.25f];
CGRect frame = self.view.frame;
frame.origin.y = frame.origin.y + 204;
[self.view setFrame:frame];
[UIView commitAnimations];
}
To move view up when keyboard is present but this results like this:
becomes this:
Can't figure out why and if it has to do something with the navbar or constraints.

Answer 1

Why not to use this beautiful library named IQKeyboardManager. Just add it through pods/manually and let it do your work

Answer 2

Kind of what Alexey Sobolevsky said did the trick. Basically i needed to put them in a scrollview and add a constraint from the scroll view to the object beneath, then put all the views containing textfields inside that scrollview instead. This made everything work correctly.

Answer 3

First add the scroll view.
Then write the following code.
//When return key press then bring the view back
-(BOOL)textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
self.scrlView.contentOffset = CGPointMake(0, 0);
return YES;
}
//When the text field begin editing then moves the view up
-(void)textFieldDidBeginEditing:(UITextField *)textField{
self.scrlView.contentOffset = CGPointMake(0, 30);
}
//When ext field end editing then bring the view back
-(void)textFieldDidEndEditing:(UITextField *)textField{
self.scrlView.contentOffset = CGPointMake(0, 0);
}
