In the “0142 Coding the add new thread functionality part 1” video, the speaker demonstrates how to add the functionality to create a new thread or conversation in their app. By adding an IBAction named “funk add button tapped” to the Thread List View Controller when the user presses the plus button, an alert controller appears, enabling users to input the name of the person they are chatting with. The alert controller consists of a text field for the person’s name, a cancel button, and a create button with a Handler that generates a new thread using the entered name and a randomly assigned color. In contrast, the speaker also mentions creating a new method called “add new thread” in the Thread class, which is called using “self.add new thread(),” but creating the “ThreadNew” object is left as a future task.
In the “0143 Coding the add new thread functionality part 2” video, the presenter tackles issues encountered while integrating the functionality to add a new thread to a list view controller. Remedial actions include prefixing “UIColor” before the problematic code and adjusting variable names from “mockThreads” to “threads” as required. They introduce a “getRandomRibbonColor” function to assign unique colors to new threads utilizing an array. The presenter proceeds to establish connections between the add button and the thread list view and implement an alert controller for initiating new conversations. However, they observe that newly created threads are not being stored locally. To address this, they propose invoking the thread manager whenever the add button is activated. Additionally, they acknowledge the necessity of refining the colors associated with added threads and encourage viewers to validate the code by creating new conversations and verifying their appearance in the thread list view. The subsequent lecture will concentrate on retrieving and storing threads.
In the “0144 Coding the add new thread functionality part 3” video, the presenter elucidates on incorporating the thread manager within the thread list to manage the storage and retrieval of conversations. They instantiate the thread manager within the thread list view, ensuring threads are added to it during the initial load. Subsequently, the threads variable is assigned to the thread manager’s threads. To integrate a new thread, adjustments are made to direct the addition to the thread manager rather than directly to the threads variable. The presenter validates the code’s functionality by setting breakpoints and running the app multiple times, confirming the successful saving and retrieval of threads by the thread manager. The forthcoming segments of the tutorial will focus on enabling the reading and deletion of threads.
