问题 I always try to present a popover from a cell inside a tableView this way: [myPopover presentPopoverFromRect:cell.frame inView:self.tableView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; but I cannot use UIPopoverArrowDirectionRight or Left, because, depending on the position of the ipad (portrait or landscape), the popover appears someplace else. Am I presenting the popover the right way? PS: the table view is in the detailView of a splitView. 回答1: Here is the simple

Popover with embedded navigation controller doesn't respect size on back nav

阅读更多关于 Popover with embedded navigation controller doesn't respect size on back nav

I have a UIPopoverController hosting a UINavigationController, which contains a small hierarchy of view controllers. I followed the docs and for each view controller, I set the view's popover-context size like so: [self setContentSizeForViewInPopover:CGSizeMake(320, 500)]; (size different for each controller) This works as expected as I navigate forward in the hierarchy-- the popover automatically animates size changes to correspond to the pushed controller. However, when I navigate "Back" through the view stack via the navigation bar's Back button, the popover doesn't change size-- it remains

My app (iPad;iOS 6) is a landscape only application, but when I try using a UIPopoverController to display the photo library it throws this error: Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES.

Does anyone know if UIPopoverPresentationController can be used to present popovers on iPhones?
