Problem in showing subview as popover - iphone

Question

I want to show the subview of a view in popover.
To elaborate,
I have a mainViewController.
I hava a subview 'songListView' in this mainViewController.
I have a button titled 'list' in the mainViewController' itself.
I want to show the songListView in popover on clicking the button 'list'.
So, how should I do this.

Answer 1

You could use the below code as a reference for showing PopOver from a UIButton
-(void) buttonAction:(id)sender {
//build our custom popover view
UIViewController* popoverContent = [[UIViewController alloc]
init];
UIView* popoverView = [[UIView alloc]
initWithFrame:CGRectMake(0, 0, 200, 300)];
popoverView.backgroundColor = [UIColor greenColor];
popoverContent.view = popoverView;
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover =
CGSizeMake(200, 300);
//create a popover controller
self.popoverController = [[UIPopoverController alloc]
initWithContentViewController:popoverContent];
//present the popover view non-modal with a
//refrence to the button pressed within the current view
[self.popoverController presentPopoverFromRect:popoverButton.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
//release the popover content
[popoverView release];
[popoverContent release];
}

My problem is solved.
I just created another View Controller class, i.e. 'TempPopoverView'.
Then I set the view of this TempPopoverView equal to the subview of my MainView
Here is the code snippet from my code:
TempPopoverView *viewController = [[TempPopoverView alloc]initWithNibName:#"TempPopoverView" bundle:nil];
[self. songListView setHidden:NO];//songListView is subview of MainView
viewController.view=self. songListView;
UINavigationController *navCont = [[UINavigationController alloc]initWithRootViewController:viewController];
navCont.navigationBar.tintColor = [UIColor colorWithRed:.102 green:.102 blue:.102 alpha:1];
[self showPopOverController:navCont andFrame:sender.frame andInView:self.view];//self.view is the MainView
[viewController release];
[navCont release];

Answer 3

U can use presentModalViewController on your main view.
For example
SongListView *songList = [[SongListView alloc] init];
[self presentModalViewController: songList animated: YES];
There are different animations possible as well.

Answer 4

as simple as you think to add subview in self.view
[popoverController.contentViewController.view addSubview:yourselfobject];
