Usage

Basic

The default RMActionController does not contain any content view. This means presenting an RMActionController only presents a set of buttons added to the RMActionController. For this task an UIAlertController can be used.

To add a content view RMActionController usually is subclassed. This project contains two subclasses of RMActionController (RMCustomViewActionController and RMMapActionController) which give two examples for a subclass of RMActionController.

Subclassing

When subclassing RMActionController you only have to overwrite one method. This method is called actionControllerWithStyle:title:message:selectAction:andCancelAction:.

+ (instancetype)actionControllerWithStyle:(RMActionControllerStyle)style title:(NSString *)aTitle message:(NSString *)aMessage selectAction:(RMAction *)selectAction andCancelAction:(RMAction *)cancelAction {
    //Create an instance of your RMActionController subclass
    RMMapActionController *controller = [super actionControllerWithStyle:style title:aTitle message:aMessage selectAction:selectAction andCancelAction:cancelAction];

    controller.contentView = [[MKMapView alloc] initWithFrame:CGRectZero];
    controller.contentView.translatesAutoresizingMaskIntoConstraints = NO;
    controller.contentView.accessibilityLabel = @"MapView";

    NSDictionary *bindings = @{@"contentView": controller.contentView};
    [controller.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[contentView(200)]" options:0 metrics:nil views:bindings]];

    return controller;
}

Presenting

Presenting any RMActionController works by using standard Apple API.

- (IBAction)openActionController:(id)sender {
    //Create select action
    RMAction *selectAction = [RMAction actionWithTitle:@"Select" style:RMActionStyleDone andHandler:^(RMActionController *controller) {
        NSLog(@"Action controller finished successfully");
    }];

    //Create cancel action
    RMAction *cancelAction = [RMAction actionWithTitle:@"Cancel" style:RMActionStyleCancel andHandler:^(RMActionController *controller) {
        NSLog(@"Action controller was canceled");
    }];

    //Create action controller and (optionally) set title and message
    RMMapActionController *actionController = [RMMapActionController actionControllerWithStyle:RMActionControllerStyleWhite selectAction:selectAction andCancelAction:cancelAction];
    actionController.title = @"Test";
    actionController.message = @"This is a test action controller.\nPlease tap 'Select' or 'Cancel'.";

    //Now just present the date selection controller using the standard iOS presentation method
    [self presentViewController:actionController animated:YES completion:nil];
}

Advanced

Presentation Style

You can use the property modalPresentationStyle to control how the action controller is shown. By default, it is set to UIModalPresentationOverCurrentContext. But on the iPad you could use UIModalPresentationPopover to present the action controller within a popover. See the following example on how this works:

- (IBAction)openActionController:(id)sender {
    //Create select and cancel action
    ...

    RMMapActionController *actionController = [RMMapActionController actionControllerWithStyle:RMActionControllerStyleWhite selectAction:selectAction andCancelAction:cancelAction];

    //On the iPad we want to show the date selection view controller within a popover.
    if([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) {
        //First we set the modal presentation style to the popover style
        actionController.modalPresentationStyle = UIModalPresentationPopover;

        //Then we tell the popover presentation controller, where the popover should appear
        actionController.popoverPresentationController.sourceView = self.view;
        actionController.popoverPresentationController.sourceRect = CGRectMake(...);
    }

    //Now just present the date selection controller using the standard iOS presentation method
    [self presentViewController:actionController animated:YES completion:nil];
}

Others

Finially, RMActionController can be used in both your main application and an action extension showing UI.
