how to return string from uipicker inside uialertview with selectedRowInComponent

I have created a uipicker in a uialertview that pops up when someone selects a UITextfield I have created this inside the 

- (void)textFieldDidBeginEditing:(UITextField *)myTextField{

method, inside this I have also created a Done and Cancel button that I have hooked up to their own methods... The one that I am having trouble with is the

-(void)doneButtonPressed:(id)sender{

Inside this method I want to catch what the uipicker has been set too.. however its giving me a warning...

-(void)doneButtonPressed:(id)sender{  
    //Do something here here with the value selected using [pickerView date] to get that value  
    [pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];
    NSString *hexString = [NSString stringWithFormat:@"%x%x%x%x%x", [pickerViewPopup selectedRowInComponent:0], [pickerViewPopup selectedRowInComponent:1], [pickerViewPopup selectedRowInComponent:2], 
                           [pickerViewPopup selectedRowInComponent:3]];

    dateCode.text = hexString;

this throws a warning UIActionSheet may not respond to SelectedRowInComponent... any idea on how to get around this warning?

Solution

  • Is it possible that you have wrongly initialize pickerViewPopup to be an object of UIActionSheet?, because the is no method called selectedRowInComponent for UIActionSheet.

    Check the pickerViewPopup initialization again, it might help.
