Multiple sources for UIPickerView on textfield editing

Question

What i have so far is

@synthesize txtCountry,txtState;
int flgTextField;
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField { 
    [pickerView reloadAllComponents];

    // Make a new view, or do what you want here
    if(textField == txtCountry || textField == txtState){
        flgTextField = textField.tag;
        [UIView beginAnimations:nil context:NULL];
        //[pvState setFrame:CGRectMake(0.0f, 199.0f, 320.0f, 216.0f)];
        [UIView commitAnimations];  
        return NO;
    }
    else {
        return YES;
    }

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

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {

    if(flgTextField==1){
        return [arryCountry count];
    }
    else {
        return [arryState count];
    }

}

- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {

    if(flgTextField==1){
        return [arryCountry objectAtIndex:row];
    }
    else{
        return [arryState objectAtIndex:row];
    }

}

 - (void)viewDidLoad {
     arryCountry = [[NSMutableArray alloc] init];
     arryState = [[NSMutableArray alloc] init];
     [arryCountry addObject:@" 100 "];
     [arryCountry addObject:@" 200 "];
     [arryCountry addObject:@" 400 "];
     [arryCountry addObject:@" 600 "];
     [arryCountry addObject:@" 1000 "];
     [arryState addObject:@" a "];
     [arryState addObject:@" b "];
     [arryState addObject:@" c "];
     [arryState addObject:@" d "];
     [arryState addObject:@" e "];
      [super viewDidLoad];
 }

in my .m and

@interface Contact : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource> {

    IBOutlet UITextField *txtCountry;
    IBOutlet UITextField *txtState; 
    NSMutableArray *arryCountry;
    NSMutableArray *arryState;
    UIPickerView *pickerView;
}
@property(nonatomic,retain) IBOutlet UITextField *txtCountry;
@property(nonatomic,retain) IBOutlet UITextField *txtState;

in my .h file

Now the text fields are not editable and I need some help or guidance, or any tutorial on how to connect UIPicker with multiple sources that can be change when text fields are editing

In textFieldShouldBeginEditing, why do you return NO for country and state fields? — , Dec 01 '10 at 15:10

So i see no one cares :)

what i have now is 3 textFields and whenever i touch textField1 or textField2 Picker changes values and there is no keyboard. When i touch textField3 keyboard appears and the picker goes hidden.Now if i dismiss the keyboard by clicking return and then click textField1 picker appears again, but if i dont dismiss the keyboard BY CLICKING BUTTON it stays over the picker. What I need is when the keyboard is firstResponder (and i see it on the screen) to hide it if i click on the textField1 and only to see the picker

    int variabla;

        -(void)textFieldDidBeginEditing:(UITextField *)textField{
            [pickerView setHidden:YES];
            if (textField1.editing == YES) {
                [textField1 resignFirstResponder];
                [pickerView setHidden:NO];
                variabla = 1;
            }else if (textField2.editing == YES) {  
                [textField2 resignFirstResponder];
                [pickerView setHidden:NO];
                variabla = 2;
            }   
            NSLog(@"variabla %d",variabla); 
            [pickerView reloadAllComponents];
        }

        - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
        {
            return 1;
        }
        - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
        {
            if (variabla == 1) {
                return [pickerArray1 count];
            }else if (variabla == 2) {
                return [pickerArray2 count];
            }else {
                return 0;
            }   
        }
        - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;
        {   
            if (variabla == 1) {
                return [pickerArray1 objectAtIndex:row];        
            }else if (variabla == 2) {
                return [pickerArray2 objectAtIndex:row];
            }else {
                return 0;
            }   
        }
        - (void)textFieldShouldReturn:(UITextField *)textField{ 
            [textField resignFirstResponder];
        }
- (void)viewDidLoad {
    [super viewDidLoad];
    [pickerView setHidden:YES];
    pickerArray1 = [[NSMutableArray alloc] initWithObjects:@"0", @"1", @"2", nil];
    pickerArray2 = [[NSMutableArray alloc] initWithObjects:@"3", @"4", @"5", nil];
}
