How to display a view made with Interface Builder

问题:

I'd like to design my views quietly in Interface Builder, then to be able to display them dynamically as an UIPopoverController.

I found this precious tutorial by Ray Wenderlich but I cannot extend it to my needs.

Anyone could help me?

Here is how I usually do it: let's say I have a parent view controller in which I want to present the popover. I declare a popover controller as a property for that VC ( @property (nonatomic, retain) UIPopoverController* popOverController; )

The code for presenting a popover with a new view controller, let's call it ViewController2, would be this one

ViewController2* viewController2 = [[ViewController2 alloc] initWithNibName:@"ViewController2"  bundle:nil];

self.popOverController = [[UIPopoverController alloc] initWithContentViewController:viewController2];

popOverController.popoverContentSize = CGSizeMake(350, 216); //or whatever size you need

//this will present the view controller from the sender's frame, assuming this code is used inside an IBAction 
//and the popover's arrow will point down
[popOverController presentPopoverFromRect:[sender frame] inView:self.view  permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES]; 

[viewController2 release];

[popOverController release];

That's pretty much it... If you run into any problems, I'll try to give you more infos.

P.S. I am not claiming this is the best way to do it, I have less than an year of experience with iOs, but that's how we usually do it where I work
