Question

Currently, these are my codes to create a picker view

genderPicker = [[UIPickerView alloc] 
                initWithFrame:CGRectMake(0, 244, 320, 270)];
genderPicker.delegate = self;
genderPicker.dataSource = self;
genderPicker.tag = 1;
genderPicker.showsSelectionIndicator = TRUE;  

The problem with this set of codes is that if the screen is scrollable, the picker would just
stay in that exact co-ordinates and will not move along with the screen when I scroll.

Could anyone assist me in animating the picker so when I scroll it up/down, the picker will follow?

Thank you.

When you are adding the picker, do not add it on self.view, instead add it on the scrollview.

For eg:-

[self.scrollview addSubView:genderPicker];

Here self.scrollview represents the scrollview. This will make sure that it moves along with the scrollview.
