PopoverView is a simple resolution-independent UIView written entirely in CoreGraphics and QuartzCore for display of modal content on both iPhone and iPad. It can display singular UIView contentViews, arrays of UIViews, display titles, or even allow selection from a list of strings. It is implemented via a very simple static interface that allows you to show the popover with just a single line. All animation, positioning, and memory allocations are handled by the component at runtime. We are releasing under the MIT License.

Demonstration

As a quick demonstration, I used a UIView from another one of my components called OCCalendar[^1]. To display this to the user on tap, I simply allocate and initialize the view, then I use a single line to display it to the user. The PopoverView handles positioning above/below the point of interest, handles all of the memory management, and manages the view stack so it gets displayed to the user at the correct location.

OCDaysView *daysView = [[OCDaysView alloc] initWithFrame:CGRectMake(0, 0, 150, 100)];
[daysView setMonth:10];
[daysView setYear:2012];
//[PopoverView showPopoverAtPoint:point inView:self.view withContentView:[daysView autorelease] delegate:self];
[PopoverView showPopoverAtPoint:point inView:self.view withTitle:@"October 2012" withContentView:[daysView autorelease] delegate:self];

As you may note, I have two versions of the display code here. One of them displays the daysView as a single contentView with no title, and the other displays the same view with a "October 2012" title.

Demo Project

The structure of the demo project is very simple. The PopoverView.h and .m files are in the "PopoverView" folder in the root directory. The demo project files are in the "popover/demo" subdirectory.
