UIPicker and send selected row data to UIView - iphone

Question

I have written a UIPicker which is populated from a .plist. This part works fine.
What I don't know how do is once the row has been selected is to display that underlying data in another UIView.
The code in my .m file is:
#import "airlinePickerViewController.h"
#implementation airlinePickerViewController
#synthesize picker;
#synthesize airlines;
#synthesize airline;
#synthesize teleno;
- (IBAction)butonPressed:(id)sender
{
NSInteger airRow = [picker selectedRowInComponent:kAirlineComponent];
NSInteger telRow = [picker selectedRowInComponent:kTelenoComponent];
NSString *air = [self.airline objectAtIndex:airRow];
NSString *tel = [self.teleno objectAtIndex:telRow];
NSString *title = [[NSString alloc] initWithFormat:#"You selected %#.", tel];
NSString *message = [[NSString alloc] initWithFormat:#"%# is in %#", tel, air];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
[title release];
[message release];
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
// Initialization code
}
return self;
}
- (void)viewDidLoad {
NSBundle *bundle = [NSBundle mainBundle];
NSString *plistPath = [bundle pathForResource:#"airlinedictionary" ofType:#"plist"];
NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
self.airlines = dictionary;
[dictionary release];
NSArray *components = [self.airlines allKeys];
NSArray *sorted = [components sortedArrayUsingSelector:#selector(compare:)];
self.airline = sorted;
NSString *selectedAirline = [self.airline objectAtIndex:0];
NSArray *array = [airlines objectForKey:selectedAirline];
self.teleno = array;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview
// Release anything that's not essential, such as cached data
}
- (void)dealloc {
[picker release];
[airlines release];
[airline release];
[teleno release];
[super dealloc];
}
#pragma mark -
#pragma mark Picker Data Source Methods
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
if (component == kAirlineComponent)
return [self.airline count];
return [self.teleno count];
}
#pragma mark Picker Delegate Methods
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
if (component == kAirlineComponent)
return [self.airline objectAtIndex:row];
return [self.teleno objectAtIndex:row];
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
if (component == kAirlineComponent)
{
NSString *selectedAirline = [self.airline objectAtIndex:row];
NSArray *array = [airlines objectForKey:selectedAirline];
self.teleno = array;
[picker selectRow:0 inComponent:kTelenoComponent animated:YES];
[picker reloadComponent:kTelenoComponent];
}
}
#end
Can anyone help me get to grips with how to complete this task.
Many thanks

Now a somehow general answer:
I assume you want to switch to a completely new View (not a subview) so the first thing you probably need is a Navigation Controller or TabBarController to facilitate pushing / switching to new Views. Before switching / pushing the new View you could assign the selected values as properties to that new View after initialization but before switching to the new View.
