Question

I have a pickerView in a popOver.
When the user selects a row from the pickerView, it should be stored into a UITextField (subject)

The method i’m having troubles is:

- (void) viewWithPickerController:(ViewWithPickerController*) viewWithPickerController didSelectValue:(NSString*) value
{   NSLog(@"selected value is: %@",value);
    subject.text = [NSString stringWithFormat:@"%@",value];
    NSLog(@"subject is: %@",subject.text);

}

Where value is the row of the pickerView: it logs the right value but it doesn’t set it to the textField subject, which seems to be null.

Where am i wrong?

You need to make sure your “subject” IBOutlet is set.

If you’re doing this picker view method before your XIB / view controller is instantiated, that would explain why subject is a nil object.

How else would you be instantiating “subject“?
