Picker and Label

[benblanchard]

Hello!

I'm quite new, so, if this is in the wrong place, I'm sorry.

Heres the problem:

I have started on a little app to improve my skills (I'm just a beginner!), and so far, I have created a Picker with quite a few rows in. Each of these rows displays a different language. Basically, they say "English", "French", "Spanish" etc.

What I want to do is have a Label that displays a piece of text in the language that is selected in the Picker. So basically, if the picker selects "Spanish", I want a piece of text displayed in the label. Whereas, when "French" is selected, it displays another piece of text.

At the moment, I have got the label to display the text in the Picker already. So it displays "Spanish" when the row on the Picker is "Spanish", but ultimately, I would like it to display a different piece of text, that is in Spanish.

Hopefully you understand me.

If it helps, heres my code so far . . .

In the .h file:

#import <UIKit/UIKit.h>

@interface HILPickerViewController : UIViewController {
	IBOutlet UIPickerView *picker;
	NSArray *languagesColumn;
	
	IBOutlet UILabel *helloLabel;
}

@property (nonatomic, retain) IBOutlet UIPickerView *picker;
@property (nonatomic, retain) NSArray *languagesColumn;
@property (nonatomic, retain) IBOutlet UILabel *helloLabel;


@end

In the .m file:

#import "HILPickerViewController.h"

@implementation HILPickerViewController

@synthesize helloLabel;
@synthesize picker;
@synthesize languagesColumn;

- (void)viewDidLoad {
    [super viewDidLoad];
	NSArray *array = [[NSArray alloc] 
			  initWithObjects:@"English",
						@"Dutch",
					  	@"French",
					  	@"German",
					  	@"Greek",
					  	@"Italian",
					  	@"Japanese",
					  	@"Korean",
					  	@"Polish",
					  	@"Portuguese",
					  	@"Russian",
					  	@"Spanish",
					        nil];
	self.languagesColumn = array;
	[array release];
}


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

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

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

- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
	
		helloLabel.text = [languagesColumn objectAtIndex:row];
	
}

Hi,
if I take it well, you need this:

.h file:
NSArray *another_array;

.m file:
- (void)viewDidLoad {
...
NSArray *array = [[NSArray alloc] initWithObjects:@"English", @"Dutch", @"French", @"German", @"Greek", @"Italian", @"Japanese", @"Korean", @"Polish", @"Portuguese", @"Russian", @"Spanish", nil];

another_array = [[NSArray alloc]
initWithObjects:@"text when select: English",
@"text when select: Dutch",
@"text when select: French",
@"text when select: German",
@"text when select: Greek",
@"text when select: Italian",
@"text when select: Japanese",
@"text when select: Korean",
@"text when select: Polish",
@"text when select: Portuguese",
@"text when select: Russian",
@"text when select: Spanish",
nil];
...
}

- (void)pickerViewUIPickerView *)thePickerView didSelectRowNSInteger)row inComponentNSInteger)component {
// helloLabel.text = [languagesColumn objectAtIndex:row];
helloLabel.text = [another_array objectAtIndex:row];
}

Thankyou!

But, thankyou very much!
