UIPicker Problem

[stephen]

Hello,

I'm trying to implement UIPicker as a subview of a current ViewController. When the user taps on a textfield, the keyboard popups instead of the UIPicker. I was pointed to the following tutorial as a guide:

UIPickerView - Creating a simple picker view - iPhone SDK Articles

My code is as follows:

NewWorkoutViewController.h

@interface NewWorkoutViewController : UIViewController  {
	IBOutlet UIBarItem *saveButton;
	IBOutlet UIBarItem *backButton;
	
	IBOutlet UILabel *time;
	//IBOutlet UITextView *routePicker;
	
	IBOutlet UIPickerView *pickerView;
	
	int counterInt;
	NSTimer *myTimer;
	
	NSInteger *startInterval;
	NSInteger *stopInterval;
	NSInteger *elapsedInterval;
}

@property (retain,nonatomic) NSTimer *myTimer;

-(IBAction)backButton;
-(IBAction)saveButton;
-(IBAction)mapButton:(id) sender;
-(IBAction)statisticsButton:(id) sender;

-(IBAction)startTimerButton;
-(IBAction)stopTimerButton;

-(IBAction)routePicker;

-(void)showActivity;

@end

NewWorkoutViewController.m

#import "NewWorkoutViewController.h"
#import "StatisticsViewController.h"

@implementation NewWorkoutViewController

@synthesize myTimer;

-(void)routePicker
{
	PickerViewController *pvController = [[PickerViewController alloc] initWithNibName:@"PickerView" bundle:[NSBundle mainBundle]];	
	[self presentModalViewController:pvController animated:YES];
}


-(void)applicationDidFinishLaunching:(UIApplication *)application
{	
	pvController = [[PickerViewController alloc] initWithNibName:@"PickerView" bundle:[NSBundle mainBundle]];
	[window addSubview:pvController.view];
	
    // Override point for customization after application launch
    [window makeKeyAndVisible];	
}


- (void)dealloc {
	[myTimer release];
    [super dealloc];
}
@end

PickerViewController.h

#import <UIKit/UIKit.h>

@interface PickerViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate>{

	IBOutlet UIPickerView *pickerView;
	NSMutableArray *list;
}

@end

PickerViewController.m

#import "PickerViewController.h"

@implementation PickerViewController


-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView{
	return 1;
}


-(NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger) forComponent:(NSInteger)component{
	return[list count];
}


-(NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
	return[list objectAtIndex:row];
}


-(void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
	NSLog(@"Selected item: %@ index of selected item: %i",[list objectAtIndex:row], row);
}


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
	
	list = [[NSMutableArray alloc] init];
	[list addObject:@"red"];
	[list addObject:@"blue"];
	[list addObject:@"yellow"];
	[list addObject:@"pink"];
}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];
    
    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


- (void)dealloc {
	[list release];
    [super dealloc];
}

At the moment pvController is giving me an error as its not declared, the tutorial has the following code in place:

@class PickerViewController;

@interface PickerViewAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
	PickerViewController *pvController;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;

@end

My PickerView is not setup as the AppDelegate, its a ViewController, so I'm not sure what to do ?

Please ignore this for the moment, I just saw something I forgot to do.

Sorry for the hassle....Stephen

I've updated the my code above with the problem.
