Package overview

Welcome to the documentation for JVMenuPopover, a customizable menu popover library for iOS. This library allows you to easily create and present a menu popover in your iOS app.

Installation

To install JVMenuPopover, you have a couple of options:

  • CocoaPods: Add pod 'JVMenuPopover' to your Podfile and run pod install.
  • Manual: Download the latest release from the GitHub repository and add the classes in your project.

Usage

The main class you will be working with is the JVMenuPopoverViewController. Here is an example of how you can create and present a menu popover:

// Create a menu popover view controller
JVMenuPopoverViewController *menuPopoverViewController = [[JVMenuPopoverViewController alloc] init];

// Customize the presentation attributes (optional)
menuPopoverViewController.arrowDirection = UIPopoverArrowDirectionUp;
menuPopoverViewController.sourceView = someView;

// Create menu items
JVMenuItem *item1 = [JVMenuItem itemWithTitle:@"Item 1" image:[UIImage imageNamed:@"item1"]];
JVMenuItem *item2 = [JVMenuItem itemWithTitle:@"Item 2" image:[UIImage imageNamed:@"item2"]];

// Add menu items to the menu popover view controller
menuPopoverViewController.items = @[item1, item2];

// Present the menu popover
[self presentViewController:menuPopoverViewController animated:YES completion:nil];

In the code above, we create a menu popover view controller and customize its presentation attributes such as the arrow direction and the source view. Then, we create menu items using the JVMenuItem class and add them to the menu popover. Finally, we present the menu popover.

Customization

JVMenuPopover provides several customization options to fit your app’s design. You can customize the appearance of the menu items, the background view, and the arrow.

Customizing menu items

You can customize individual menu items by setting their appearance properties:

JVMenuItem *menuItem = [[JVMenuItem alloc] init];
menuItem.title = @"Custom Title";
menuItem.font = [UIFont boldSystemFontOfSize:16.0];
menuItem.textColor = [UIColor redColor];

Customizing the background view

You can customize the background view of the menu popover by setting its appearance properties:

JVMenuPopoverBackgroundView *backgroundView = [[JVMenuPopoverBackgroundView alloc] init];
backgroundView.fillColor = [UIColor lightGrayColor];
backgroundView.cornerRadius = 5.0;

Customizing the arrow

You can customize the appearance of the arrow by setting the arrowImage property of the menu popover view controller. The image specified will be used as the arrow image:

UIImage *arrowImage = [UIImage imageNamed:@"custom_arrow"];
menuPopoverViewController.arrowImage = arrowImage;

Delegate

JVMenuPopover provides a delegate protocol JVMenuPopoverDelegate that allows you to respond to user interactions with the menu popover. You can implement the following optional methods:

Responding to item selection

You can implement the menuPopover:didSelectItemAtIndex: method to respond to item selection:

- (void)menuPopover:(JVMenuPopoverViewController *)menuPopover didSelectItemAtIndex:(NSUInteger)index {
    NSLog(@"Item at index %lu selected", (unsigned long)index);
}

In the code above, the method gets called when the user selects an item in the menu popover. You can perform any custom logic based on the selected item’s index.

Responding to dismissal

You can implement the menuPopoverDidDismiss: method to respond to the menu popover being dismissed:

- (void)menuPopoverDidDismiss:(JVMenuPopoverViewController *)menuPopover {
    NSLog(@"Menu popover dismissed");
}

In the code above, the method gets called when the menu popover is dismissed. You can perform any necessary cleanup or additional actions.

Conclusion
