The App Will Have Three Tabs As In Cs App The First Tab The ✓ Solved

The app will have three tabs (as in CS app). The first tab (the left one) will present five companies/persons and a switch for each. You can choose (update) these companies/persons as you wish. Once the user wants to see a company's twitter and/or facebook pages, she/he makes this company's radio button ON. So, a company/person is selected in "company" tab, then user may go (touch) to Twitter and FaceBook tabs.

Each of these tabs has UIWebView to display twitter and facebook pages for the selected company in the first tab. Make sure that once user started the app, the last company (ABC bank in above schema) will be selected by default. You need to keep this data in a file or in user setting permanently even if the app is closed. If the user makes all switches off, then Twitter and FaceBook tab will show an error/warning, such as "Please make a selection first". User will not be able to make more than "one" ON selection among five radio buttons. If she/he tries to make two "ON"s among them, automatically set previous switch ON to OFF. Make sure that you made https request in your app to FB and Twitter. Otherwise you need to configure your app's plist file so that you can load http sites.

HINT: How to use user default setting of an app to keep data: // This section is from FlagGame, model.swift private let guessesKey = "FlagQuizKeyGuesses" // get the NSUserDefaults object for the app let userDefaults = NSUserDefaults.standardUserDefaults() // get number of guesses let tempGuesses = userDefaults.integerForKey(guessesKey) if tempGuesses != 0 { numberOfGuesses = tempGuesses }

Paper For Above Instructions

The application described is a mobile app featuring three distinct tabs, each performing specific roles integral to user interaction and experience. The overarching design principle centers on simplicity and usability, allowing users to easily navigate between different functionalities while maintaining a cohesive and intuitive interface. The first tab, which prominently displays five selectable companies or individuals, acts as the control center for the rest of the app, controlling what information the user can view on the next two tabs.

Tab Structure and Functionality

The layout consists of three tabs: the "Company" tab on the left, followed by "Twitter," and "Facebook." In the "Company" tab, each of the five companies will have an accompanying radio button toggle, representing whether that particular company is selected. The functionality of these radio buttons is crucial, as only one button can be activated at any given time. When a user selects a company by turning its radio button on, the app will subsequently prepare to load content relevant to that company when the user navigates to the Twitter or Facebook tabs.

For instance, if the user wants to view the Twitter feed of "ABC Bank," they will first tap the radio button beside the "ABC Bank" option in the "Company" tab. This process will ensure that subsequent taps on the Twitter or Facebook tabs retrieve and display the correct information associated with ABC Bank. It's important to note that radio button functionality prevents the user from selecting more than one company at the same time, ensuring a focused browsing experience.

Default Selection and User Settings

When the app launches, it is crucial that the last selected company—based on the user's previous interactions—be selected by default. This default selection enhances user experience, as it minimizes waiting time for the user and offers a seamless transition between app sessions. To achieve this functionality, user settings will be utilized to store the latest selection. This could be achieved through persistent storage mechanisms such as the UserDefaults in iOS development, ensuring that selections persist even after the application has been closed. The implementation could mirror the provided code snippet for storing and retrieving user defaults effectively.

Error Handling and User Feedback

If a situation arises where all radio buttons are switched off, the app must provide feedback to the user. Navigating to the Twitter or Facebook tabs in such a scenario could trigger an error message, perhaps something like, "Please make a selection first." This prompts the user to interact with the Company tab and review their selection, thereby maintaining a seamless flow in navigation and interaction with the app.

Web Content Display with UIWebView

The "Twitter" and "Facebook" tabs are designed to display the respective feeds of the selected company via an embedded UIWebView. This allows users to view content directly within the app, enhancing convenience. However, it is important to ensure that HTTP requests are secure; thus, making HTTPS requests to Twitter and Facebook is crucial. This not only aligns with best practices for data security but also assures users that their app experience is safeguarded from potential vulnerabilities associated with unsecured data transmission.

Technical Configuration and Implementation

Furthermore, it may be necessary to configure the app's Info.plist file if there are issues loading paged content from unsecured sites. This configuration ensures the app can interact with HTTP sites while still prioritizing security by encouraging HTTPS usage. Developers must ensure that this aspect of the configuration is handled with care in order to preserve both user experience and safety.

Conclusion

The app's three-tab functionality embodies a rich user experience, enriched by seamless navigation, intuitive design, and thoughtful error handling. By focusing on user selection, appropriate error messaging, and secure content loading practices, this app stands to provide users with a comprehensive platform to engage with their selected companies' social media presence. As mobile applications continue to evolve, features like those described above will become increasingly necessary to ensure user satisfaction and retention.
