Change / Customize Picker Size

Thank you for your help. If there are delegates for the height and width can these be changed to change the size of the picker?

An example of a smaller size is found on an app like check please for the iphone.

Thanks for your help. I'm trying to experiment adding the code you should me of:

smallerPicker [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 120.0)

where exactly do I put this and do I need to change anything else?

Here is my implementation file coding:
//
// SingleComponentPickerViewController.m
// Pickers
//

#import "SingleComponentPickerViewController.h"


@implementation SingleComponentPickerViewController
@synthesize singlePicker;
@synthesize pickerData;

- (id)initWithNibName:(NSString *)nibNameOrNil
bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil
bundle:nibBundleOrNil]) {
// Custom initialization
}
return self;
}
- (IBAction)buttonPressed
{
NSInteger row = [singlePicker selectedRowInComponent:0];
NSString *selected = [pickerData objectAtIndex:row];
NSString *title = [[NSString alloc] initWithFormat:
@"You selected %@!", selected];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:@"Thank you for choosing."
delegate:nil
cancelButtonTitle:@"You're Welcome"
otherButtonTitles:nil];
[alert show];
[alert release];
[title release];
}
- (void)viewDidLoad {
NSArray *array = [[NSArray alloc] initWithObjects:@"Luke", @"Leia",
@"Han", @"Chewbacca", @"Artoo", @"Threepio", @"Lando", nil];
self.pickerData = array;
[array release];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceO rientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (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)dealloc {
[singlePicker release];
[pickerData release];
[super dealloc];
}

#pragma mark Picker Data Source Methods
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component
{
return [pickerData count];
}
#pragma mark Picker Delegate Methods
- (NSString *)pickerView:(UIPickerView *)pickervView
titleForRow:(NSInteger)row
forComponent:(NSInteger)component
{
return [pickerData objectAtIndex:row];
}
@end




and here is my header file coding:

@interface SingleComponentPickerViewController : UIViewController
<UIPickerViewDelegate, UIPickerViewDataSource> {
IBOutlet UIPickerView *singlePicker;
NSArray *pickerData;
}
@property (nonatomic, retain) UIPickerView *singlePicker;
@property (nonatomic, retain) NSArray *pickerData;
- (IBAction)buttonPressed;
@end

Here is a handy tidbit I received from a programmer.

- (void)viewDidLoad
{
CGRect frame = pickerView.frame;
pickerView.frame = CGRectMake(frame.origin.x, frame.origin.y, 120, frame.size.height);
}
