UIButton does not respond to touchupinside when in a uipopover - iphone

Question

I added a button to my UIPopoverController but it appears to not respond to touches. I don't know if I am supposed to set some property on the UIPopoverController or what. Here is the code that renders the popover view and button.
- (void)topicImageButtonPressed
{
CGRect aFrame = CGRectMake(0.0, 0.0, 1000.0, 600.0);
UIViewController *aView = [[UIViewController alloc] init];
aView.view.frame = aFrame;
UIImageView *iView = [[UIImageView alloc] init];
[iView setContentMode:UIViewContentModeScaleAspectFit];
[iView setImage:self.topicImageView1.image];
aView.view = iView;
UIButton *nextButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[nextButton addTarget:self
action:#selector(quizButtonPressed:)
forControlEvents:UIControlEventTouchUpInside];
[nextButton setTitle:#"Next" forState:UIControlStateNormal];
nextButton.frame = CGRectMake(700.0, 550.0, 160.0, 40.0);
[aView.view addSubview:nextButton];
//aView.view.backgroundColor = [UIColor colorWithPatternImage:self.topicImageView1.image];
imagePopoverController = [[UIPopoverController alloc]
initWithContentViewController:aView];
imagePopoverController.popoverContentSize = CGSizeMake(1000, 600);
imagePopoverController.passthroughViews = [NSArray arrayWithObject:nextButton];
[imagePopoverController presentPopoverFromRect:CGRectMake(212, 10, 1000, 600) inView:self.view
permittedArrowDirections:0 animated:YES];
}

Answer 1

Adding this made it work.
iView.userInteractionEnabled = YES;

Answer 2

UIViewController *popoverContent = [[UIViewController alloc]init];
UIView *popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 768, 1024)];
datepiker= [[UIDatePicker alloc]init];
[datepiker setFrame:CGRectMake(0, 0, 320, 216)];
datepiker.datePickerMode=UIDatePickerModeDateAndTime;
datepiker.hidden=NO;
datepiker.minimumDate=[NSDate date];
[self.view addSubview:datepiker];
[datepiker release];
// [datepiker addTarget:self action:#selector(changedDate:) forControlEvents:UIControlEventValueChanged];
btn_add=[[UIButton alloc]initWithFrame:CGRectMake(115, 250, 100, 30)];
[btn_add setTitle:#"Add" forState:UIControlStateNormal];
[btn_add setFont:[UIFont fontWithName:#"Arial-BoldMT" size:20]];
[btn_add setBackgroundColor:[UIColor redColor]];
[btn_add addTarget:self action:#selector(AddDate:) forControlEvents:UIControlEventTouchUpInside];
[popoverView addSubview:btn_add];
btn_cancel=[[UIButton alloc]initWithFrame:CGRectMake(115, 300, 100, 30)];
[btn_cancel setTitle:#"Cancel" forState:UIControlStateNormal];
[btn_cancel setFont:[UIFont fontWithName:#"Arial-BoldMT" size:20]];
[btn_cancel setBackgroundColor:[UIColor redColor]];
[btn_cancel addTarget:self action:#selector(CancelDate:) forControlEvents:UIControlEventTouchUpInside];
[popoverView addSubview:btn_cancel];
[popoverView addSubview:datepiker];
[popoverView addSubview:btn_add];
popoverContent.view = popoverView;
popoverContent.contentSizeForViewInPopover = CGSizeMake(320,350);
self.popoverController = [[UIPopoverController alloc]
initWithContentViewController:popoverContent];
[self.popoverController presentPopoverFromRect:CGRectMake(230,250, 320,220)
inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
[popoverView release];
[popoverContent release];
-(void)AddDate:(id)sender
{
}
-(void)CancelDate:(id)sender
{
[popoverController dismissPopoverAnimated:YES];
}
try this .. it works for me successfully.
