We can create animated and customisable bubble menu for iOS using LIVBubbleMenu. Here is a link from GitHub for the project https://github.com/limitlessvirtual/LIVBubbleMenu-iOS.

In the following example we are going to show bubble menu on the click of a UIButton.

First include the cocoaPod for it :- 

pod 'LIVBubbleMenu'

In your Xcode project, in the Main.Storyboard drag a UIButton and create its IBAction and IBOutlet. Then in the ViewController import the LivBubbleMenu framework and also include its delegate as :-

#import <LIVBubbleMenu/LIVBubbleMenu.h>

@interface ViewController : UIViewController <LIVBubbleButtonDelegate>

In this example we are displaying images in the bubbles when the button is clicked so we take an array of images. In the ViewController.m include the following lines of code :-

@interface ViewController (){
    LIVBubbleMenu *bubbleMenu; 
    NSArray *images;
}

@end

@implementation ViewController

- (void)viewDidLoad {
   
     [super viewDidLoad];

     images = [NSArray arrayWithObjects:
                       [UIImage imageNamed:@"backgrounds"],  
                       [UIImage imageNamed:@"background3"],
                       [UIImage imageNamed:@"background2"],
                       [UIImage imageNamed:@"date"],
                       [UIImage imageNamed:@"first"],
                       [UIImage imageNamed:@"home"],
                       [UIImage imageNamed:@"index"],
                       nil];
}

Now in the action of the button perform the following lines of code :-

- (IBAction)btnShowBubbleMenu:(id)sender {
    
    bubbleMenu = [[LIVBubbleMenu alloc] initWithPoint:self.btnShowBubbleMenuOutlet.center radius:200 menuItems:images inView:self.view];
   
    bubbleMenu.delegate = self;
   
    bubbleMenu.easyButtons = NO;
  
    [bubbleMenu show];
}

As we have set the delegate to self, so we have to implement its delegates methods as :-

-(void)livBubbleMenu:(LIVBubbleMenu *)bubbleMenu tappedBubbleWithIndex:(NSUInteger)index {   // called when bubble is selected

    NSLog(@"User has selected bubble index: %tu", index);
}

-(void)livBubbleMenuDidHide:(LIVBubbleMenu *)bubbleMenu { // called on bubbles hide

    NSLog(@"LIVBubbleMenu has been hidden");
}

Build the program and see the effects. The output will be as shown below:-
