UIPopover ¿Cómo hago una ventana emergente con botones como este?

Question

Me pregunto cómo puedo crear una ventana emergente con botones como este.

RESPONDER:

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];

En otro lugar en tu clase de objeto delegado ...

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
// take photo...
}
else if (buttonIndex == 1) {
// choose existing photo...
}
}

Este es un UIActionSheet . En el iPhone, se anima desde la parte inferior. En el iPad aparece en una ventana emergente.

Suponiendo que esté haciendo esto presionando un botón:

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];

En iOS8 +, debes usar la nueva clase UIAlertController :

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];

o en Swift

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)

Similar a las otras respuestas, pero esto es muy fácil de implementar en comparación.

Haga que su clase use el UIActionSheetDelegate.

Ejemplo:

@interface ExampleViewController : UIViewController <UIActionSheetDelegate>

Luego agregue a su ExampleViewController.mm/m

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { //Get the name of the current pressed button
NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex];
if ([buttonTitle isEqualToString:@"Remove"]) {
NSLog(@"Remove this actionSheet"); }
if ([buttonTitle isEqualToString:@"Button 1"]) {
NSLog(@"Button 1 pressed"); }
if ([buttonTitle isEqualToString:@"Button 2"]) {
NSLog(@"Button 2 pressed"); }
if ([buttonTitle isEqualToString:@"Button 3"]) {
NSLog(@"Button 3 pressed"); }
if ([buttonTitle isEqualToString:@"Cancel"]) {
NSLog(@"Cancel clicked (anywhere away from it)"); } }

Ahora, en un evento de botón presionado o cuando / cuando desee que aparezca un mensaje emergente, haga lo siguiente:

 - (IBAction)aButtonPressed:(id)sender {
NSString *actionSheetTitle = @"Action Sheet"; // Title
NSString *destroyTitle = @"Destroy"; // Button titles
NSString *button1 = @"Button 1";
NSString *button2 = @"Button 2";
NSString *button3 = @"Button 3";
NSString *cancelTitle = @"Cancel";
UIActionSheet *actionSheet = [[UIActionSheet alloc]
                              initWithTitle:actionSheetTitle
                              delegate:self
                               cancelButtonTitle:cancelTitle
                             destructiveButtonTitle:destroyTitle
                              otherButtonTitles:button1, button2, button3, nil]; [actionSheet showInView:self.view];
}
