UIpicker view data source

I'm a IOS noob and I'm trying to understand how to set the datasource of of the uipicker view i have followed This tutorial, everything seems to work correctly however i get a warning in xcode that says

'id<UIPickerViewDataSource>' from incompatible type 'StateViewController *const __strong'

it occurs on this line. 

myPickerView.delegate = self;

I keep trying different things but they all lead me in the same direction. It fails. How should i be doing this? how to i properly set the datasource of a UIpicker view.

Thanks in advance for your guidance.

Step 1: Add UIPickerViewDataSource delegate in your header file

@interface StateViewController : UIViewController <UIPickerViewDataSource>

Step 2: Now add the following line in your class file

myPickerView.dataSource = self

You need to say 

myPickerView.dataSource = self

and also

<UIPickerViewDataSource>

You just need to tell the compiler that you're going to conform to the delegate protocol. You do that by adding <UIPickerViewDataSource> to your .h file,

@interface StateViewController : UIViewController <UIPickerViewDataSource>
