Question

I m curious about how to implement a drop down menu from a UIBarButtonItem like in the portrait orientation on iPad s split view. How is this done? I would have tried searching for it myself, but I don t really know exactly what I should be searching for.

Thanks in advance!

然后,在班次中,你想要打开这个pop。

@interface TheClassWerePopoverIsShown : UIViewController {
    UIPopoverController *popover;
}

if ([popover isPopoverVisible]) {
        [popover dismissPopoverAnimated:YES];
    }
    else {
        THECLASSTOSHOW *popie = [[THECLASSTOSHOW alloc]init];
        popover = [[UIPopoverController alloc]
                   initWithContentViewController:popie];
        popover.popoverContentSize = CGSizeMake(300, 700);
        [popie release];
        [popover presentPopoverFromBarButtonItem:THEBARBUTTONITEM permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
