// Header .h
#include "WEPopoverController.h"

// Create a label with custom text 
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 40)];
[label setText:@"Bookmark it!"];
[label setBackgroundColor:[UIColor clearColor]];
[label setTextColor:[UIColor whiteColor]];

[label setFont:font];
CGSize size = [label.text sizeWithFont:font];
CGRect frame = CGRectMake(0, 0, size.width + 10, size.height + 10); // add a bit of a border around the text
label.frame = frame;

//  place inside a temporary view controller and add to popover
UIViewController *viewCon = [[UIViewController alloc] init];
viewCon.view = label;
viewCon.contentSizeForViewInPopover = frame.size;		// Set the content size

navPopover = [[WEPopoverController alloc] initWithContentViewController:viewCon];
