UIDatePicker and UITextView

Question

Hi

Sorry if i did wrong english typing

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 selected.

    - (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];
}
