The correct answer to my question is as follows:

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

             if (component == 0)
    {

        NSString *resultString = [[NSString alloc] initWithFormat:@"Proje Adı : %@", [[RaporlarList objectAtIndex:row] ProjeAdii]];
        lblProjeAdi.text = [NSString stringWithFormat:@"%@", resultString];

    }
    else
    {
        NSString *resultString = [[NSString alloc] initWithFormat:@"Proje No: %@", [[RaporlarList objectAtIndex:row] ProjeNoo]];
        lblProjeNo.text = resultString;

    }

           }

You have selected wrong datasource for pickerview.

You are returning string, instead return the label

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component
{

        // return your UILabel
}
