これはUIActionSheet
です。iPhoneでは、下からアニメートします。iPadではポップオーバーで表示されます。
ボタンを押すだけでこれを実行していると仮定します。
UIActionSheet * actionSheet = [[UIActionSheet alloc] initWithTitle: nil
delegate: self
cancelButtonTitle: nil
destructiveButtonTitle: nil
otherButtonTitles: @"Take Photo",
@"Choose Existing Photo", nil];
[actionSheet showFromRect: button.frame inView: button.superview animated: YES];
iOS8 +では、新しいUIAlertController
クラスを使用する必要があります。
UIAlertController * alertController = [UIAlertController alertControllerWithTitle: nil
message: nil
preferredStyle: UIAlertControllerStyleActionSheet];
[alertController addAction: [UIAlertAction actionWithTitle: @"Take Photo" style: UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
// Handle Take Photo here
}]];
[alertController addAction: [UIAlertAction actionWithTitle: @"Choose Existing Photo" style: UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
// Handle Choose Existing Photo here
}]];
alertController.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController * popover = alertController.popoverPresentationController;
popover.permittedArrowDirections = UIPopoverArrowDirectionUp;
popover.sourceView = sender;
popover.sourceRect = sender.bounds;
[self presentViewController: alertController animated: YES completion: nil];
またはSwiftで
let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)
alertController.addAction(UIAlertAction(title: "Take Photo", style: .Default, handler: { alertAction in
// Handle Take Photo here
}))
alertController.addAction(UIAlertAction(title: "Choose Existing Photo", style: .Default, handler: { alertAction in
// Handle Choose Existing Photo
}))
alertController.modalPresentationStyle = .Popover
let popover = alertController.popoverPresentationController!
popover.permittedArrowDirections = .Up
popover.sourceView = sender
popover.sourceRect = sender.bounds
presentViewController(alertController, animated: true, completion: nil)
