UIPicker view and UITable view

Question

I am facing on common error in both UIPickerview and UITableview, i.e.

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0x4d32080> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key CurrencyPicker.'

and

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0x4b2c070> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key tableView.'

Please help me why these are.

I think it is due to datasource and delegate connection of tableview and picker view to fileowner. but I have done every thing right.

Plz help me out.

Thanks.

Right click the XIB file with the errors and choose to open as source. Can you find the occurrences of the both `CurrencyPicker` and `tableView` and post it here? — Deepak Danduprolu, May 28 '11 at 03:25

@Aman: Here is code:

@ Aman:in setting.h

@interface Setting : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>{
    UIButton *button;

    NSMutableArray *CurrencyArray;
    IBOutlet UIPickerView *CurrencyPicker;
}

in setting.m

- (void)viewDidLoad {
    [super viewDidLoad];

    CurrencyArray = [[NSMutableArray alloc] init];
    [CurrencyArray addObject:@" Rs "];
    [CurrencyArray addObject:@" R$ "];
    [CurrencyArray addObject:@" $ "];
    [CurrencyArray addObject:@" ƒ "];
    [CurrencyArray addObject:@" ман "];

    button=(UIButton *)[self.view viewWithTag:1];

    [CurrencyPicker selectRow:1 inComponent:0 animated:NO];
    [button setTitle:[CurrencyArray objectAtIndex:[CurrencyPicker selectedRowInComponent:0]] forState:UIControlStateNormal];
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
    return 1;
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    [button setTitle:[CurrencyArray objectAtIndex:row] forState:UIControlStateNormal];
}

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

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