UIDatePicker and UITextView

I want to show a text in UITextView depend on the date, some thing like "in This Day App", I have this code in action

-(void)changingText:(id)sender {

    NSDateFormatter *df = [[NSDateFormatter alloc] init];

    df.dateStyle = NSDateFormatterMediumStyle;

    label.text = [NSString stringWithFormat:@"%@", [df stringFromDate:datePicker.date]];
    NSDictionary *pageData = [[DataSource sharedDataSource] dataForPage:pageIndex];

    NSString *dateText = [pageData objectForKey:@"pageName"];

    NSString *dateInfo = [df stringFromDate:datePicker.date];

    if ([dateText isEqualToString: dateInfo]) {
        myText.text = [pageData objectForKey:@"pageText"];
    }
    [df release];
}

My qustion is how to update UITextView With the data from NSDictionery ForKey@"pageText" , because it shows just the first object.

here is the Object that i want to triger when the date been se开发者_开发百科lected.

- (id)init {
    self = [super init];
    if (self != nil)
    {
        dataPages = [[NSArray alloc] initWithObjects:
                     [NSDictionary dictionaryWithObjectsAndKeys:
                      @"Oct 3, 2009", @"pageName",
                      @"First Object", @"pageText",
                      nil],

                     [NSDictionary dictionaryWithObjectsAndKeys:
                      @"Oct 10, 2009", @"pageName",
                      @"second Object", @"pageText",
                      nil],

                     [NSDictionary dictionaryWithObjectsAndKeys:
                      @"Oct 27, 2009", @"pageName",
                      @"Third Object", @"pageText",
                      nil],                      
                     nil];
    }
    return self;
}

I'm not sure if I understand your question, but I think you need to make the object from your dictionary into an NSString like this:

-(void)changingText:(id)sender{
    NSDateFormatter *df = [[NSDateFormatter alloc] init];

    df.dateStyle = NSDateFormatterMediumStyle;

    NSDictionary *pageData = [[DataSource sharedDataSource] dataForPage:pageIndex];
    NSString *dateText = (NSString *)[pageData objectForKey:@"pageName"];
    NSString *dateInfo = [df stringFromDate:datePicker.date];

    label.text = [NSString stringWithFormat:@"%@", [df stringFromDate:dateInfo]];
    if ([dateText isEqualToString: dateInfo]) {
        myText.text = dateText;
    }

    [df release];
}
