ToDo List App – Objective-C Workshop

A professional task management application built using Objective-C and UIKit. This app is designed for efficient task organization, local data persistence, and clear prioritization using a structured categorization system.

Features

Core Functionality

• Task Creation: Add new tasks with a name, detailed description, and priority level.
• Priority Visuals: Features three priority levels (High, Medium, and Low), each represented by its own unique image for clear identification.
• Task States: Manage the lifecycle of a task through three stages:
  • To-Do: The initial state.
  • In Progress: Once started, a task cannot be reverted to "To-Do."
  • Done: Once finished, a task cannot be moved back to "In Progress."
• Data Persistence: All tasks are saved locally, ensuring your data is preserved every time you visit the app.

Management & Organization

• Segmented Control Navigation: Effortlessly switch views between:
  • All Notes: A complete list of your tasks.
  • Status Views: Filter by To-Do, In Progress, or Done.
  • Priority View: Tasks are organized into different sections based on their priority level (High/Med/Low).
• Search Interface: Quick search by task name. If no results are found, a "pretty" empty state is displayed to inform the user.
• Edit & Remove:
  • Edit existing tasks with a mandatory confirmation dialog before changes are finalized.
  • Delete any task from the list at any time.

What's New — Xcode 14.3 Refactor

The project was refactored and migrated to Xcode 14.3 with the following additions:

App Icon

Custom app icon added to Assets.xcassets, covering all required iOS sizes (20pt–1024pt) across 1x, 2x, and 3x scales.

Splash Screen

A branded launch screen configured via LaunchScreen.storyboard, displayed on cold launch before the main view controller loads.

Local Notifications — Task Reminders

Integrated UNUserNotificationCenter to schedule local push notifications that remind you about pending tasks — even when the app is backgrounded or closed.

Permission request on first launch:

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert |
                                         UNAuthorizationOptionSound |
                                         UNAuthorizationOptionBadge)
                      completionHandler:^(BOOL granted, NSError *error) {
    if (granted) {
        NSLog(@"Notification permission granted.");
    }
}];

Scheduling a reminder when a task is created or updated:

UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = @"Task Reminder";
content.body  = task.name;
content.sound = [UNNotificationSound defaultSound];

UNTimeIntervalNotificationTrigger *trigger =
    [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:3600 repeats:NO];

UNNotificationRequest *request =
    [UNNotificationRequest requestWithIdentifier:task.taskID
                                         content:content
                                         trigger:trigger];

[[UNUserNotificationCenter currentNotificationCenter]
    addNotificationRequest:request
     withCompletionHandler:nil];

Note: For full notification behavior (background delivery), testing on a physical device is recommended.
