iOS How do something after touching a pickerview item?

[skunkio]

Hi all,
how can i do "something" when i touch a pickerview item?
In my app i have a pickerview filled using an array, now, when i touch (select) a specific item i would do another action. I didn't find nothing on google.
Any idea?

Ciao,

Hi,
you can look all delegate methods for UIPickerView by typing UIPickerViewDelegate in xcode docs...

the one you need is...

- (void)pickerView:(UIPickerView *)_pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
}

dont forget to set pickerViews delegate...

What did you Google for?

Your first stop should probably have been the documentation for UIPickerView, where the Overview includes this:

A UIPickerView object requires the cooperation of a delegate for constructing its components and a data source for providing the numbers of components and rows. The delegate must adopt the UIPickerViewDelegate protocol and implement the required methods to return the drawing rectangle for rows in each component. It also provides the content for each component’s row, either as a string or a view, and it typically responds to new selections or deselections.

(Emphasis mine).
