I have a superUIView
which has a subUIView
. The subUIView
has the UIPanGestureRecognizer
.
I need to move the superUIView
when the user tries to move the subUIView
.
I do not want to set the center as that would give a jerk.
I need to move the superUIView
smoothly when the user tries to move the subUIView
.Because the superUIView
is moving, the user will get the feeling that he is moving the subUIView
.
So, I how do I get this done?

assuming you set the frame of the subUIView
when the gesture recognizer triggers, just move the super view the same amount
subview.frame = CGRectMake(-x,-y,w,h); //move opposite way to superview
[subview superview].frame = CGRectMake(x,y,w,h); //move
edit: misinterpreted what you were trying to accomplish a bit, you would need to move the subview the opposite way to which the superview is moving for the subview to stay in place while the superview moves

You can set the center to avoid jerk use UIView
animation block
[UIView animateWithDuration:0.5
animations:^{
//set center here
}
completion:^(BOOL finished) {
}];
