How do I make a UIPickerView in a UIActionSheet

Question

Just want to know how I would make a UIPickerView in a UIActionSheet with a simple array.

Answer 1

You don't want to do that. Instead, create your UIPickerView in Interface Builder and connect it to an Outlet in your view controller. Add it as a subview of your main view and set its frame coordinates so that it is offscreen just below the bottom edge, x=0, y=480.

Then, when you want to display the picker, animate it onto the screen with something like:

[UIView beginAnimations:nil context:NULL];
[colorPicker setFrame:CGRectMake(0.0f, 416.0f, 320.0f, 216.0f)];
[UIView commitAnimations];

And then hide it when you're done picking with this:

[UIView beginAnimations:nil context:NULL];
[colorPicker setFrame:CGRectMake(0.0f, 480.0f, 320.0f, 216.0f)];
[UIView commitAnimations];

This will cause your picker to slide up from the bottom animated and slide back down when you're done.

I don't think adding a picker to a UIActionSheet, if it's even possible, is advisable.

Answer 2

Ok well I actually found out how to put it into an action sheet but I like your way better because it applies more to my app, thanks, but I want to also know how put the options into the UIPickerView, I am just hung up on that part of that. I already have an array with the colors: red, green, blue, yellow, black, etc in it but I want to know how to put that into the pickerview if I have already used initwithframe:? Please anyone help I know it is a stupid question but I'm racking my head on my $$$$$$ Macbook.
