Implement the UIPickerViewDataSource methods :

– numberOfComponentsInPickerView:
– pickerView:numberOfRowsInComponent:

and UIPickerViewDelegate :

– pickerView:titleForRow:forComponent:

Don't forget to set properties:



UIPickerView * myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];
myPickerView.delegate = self;
myPickerView.dataSource = self;
[self.view addSubview:myPickerView];

And in the .h file, don't forget to put:

<UIPickerViewDelegate, UIPickerViewDataSource>

I usually use NSMutableArray

filled with strings to fill in the data. Hope it helps!
