How to Come up with the Perfect iPhone Apps

• The 1st factor: Defining the Concept
  Even before Xcode is opened for the first time, a well-conceived app should be planned with features that stand out. The design document outlines app functionality and details UI and flows between screens. Basic ideas of types of systems that have to undergo implementation are also crucial.
  The design document should be adhered to while coming up with the app. You need to focus on features you need and draw the sketch for each screen in the application.At least one thumbnail sketch is a must
• The 2nd Factor: Assessing your Audience
  You need to be very clear about who the app is being designed for. The target audience is an essential point to consider. As this app development is for iPhones, you need to consider aspects like functionality, practicality, and efficiency
• The 3rd Factor: If there is a Problem, Your App Should be the Solution
  You also need to be clear about the requirements you are meeting with the app. In case the app is a game, it has unique features that set it apart and attract gamers
• The 4th Factor: Consider the Content
  The user interface will be assessed by nature oft the contents one is displaying to the user of the app. If the app deals with fitness, you need a user interface that is easy to navigate and use during workouts
• The 5th Factor: Working on the User Interface
  Good UI design processes need to be practiced. The user interface should always be designed keeping the needs of the user in mind. It should be intuitive and ergonomic. Navigation via the app should be smooth and seamless. Remember, the user interface is as much an art as it a science.

App Creation: Key Phases

In the first phase, you need to create a project in Xcode. You can open up Xcode and commence with a new project from the File menu. In the template section, you need to select an empty application.

Numerous templates are available for differing kinds of tasks. Start with a blank template and fill it as you go along. Try one of the more complex templates once you have exhausted the simple ones. One also needs to provide the product name, class prefixes and company identifiers. Apple provides the company identifier.

In the second phase, you need to come up with the storyboard which is basically a visual representation of the different screens of an app. This displays the contents of the screen as well as changes between them.

In the third phase, the created storyboard has to become the main interface of your application. This loads the storyboard once the app has been launched. Add screens using the view controller and complete scenes using the object library.

Finally, you need to click and drag objects from the list to add to the screen. Many objects can be resized through boxes which can be clicked and dragged towards the end of the object. Customization of objects is the next step. Properties for each object have to be adjusted creating a personalized and user-friendly interface. Choose the object which is you seeking to customize and design it using the Attributes Inspector. Switch between font style, size, text, color, alignment, placeholder text, border style and more.

As the app grows in size, more screens need to be added. You also need to add a navigation bar so users and move between screens and the navigation controller should appear towards the start of the screen. You need to make the navigational bar functional and add a title and a property enriched button to it. The new button should be linked to the existing screen. For the button to function effectively, it needs to be connected to another screen. Linking the button involves holding control and dragging the button onto the second screen. In this way, multiple screens can be linked. Cancel and done buttons need to be created as well. iPhone apps must have data handling capacities and a navigable interface prototype. A working interface translates into easier coding.

App Testing

Finally, testing the app involves the use of the iOS simulators that enable users to test the app on numerous simulated iOS devices. App building is the key step that follows. You need to click the build button. Once the process is complete, the app can be tested. A litmus test of whether the app is effective or not is how it fares on your iPhone.

App Debugging

If your application keeps crashing, you need to figure out what is happening and how. Googling the error message may work but visiting the Apple development forum is a better idea. Chances are high that if you are caught in a storm of queries, a seasoned developer may be able to rescue you and be the bridge over troubled waters.

Debugging per say is a time-consuming process which is also extremely tedious. Persisting will get you somewhere because you will recognize errors, track them effectively and expect them on occasions. Forgetting to allocate memory and initializing the object prior to adding or assigning to it can be detrimental. Moreover, if the object is released more than a single time from memory, common mistakes will follow. Errors will only lessen if you put in more effort.

You also need to check memory usage and allocate each object with some memory. iPhone SDK tool can be used to view and engage in analyzing memory usage, apart from other functions. Running with the performance tools will launch the instruments and kickstart the app on your device. You have to use the app in a normal way, but ensure that it has extraordinary properties. Leaked objects should be clicked so that you can take on a responsible code and where the leak is detected is not necessarily where it has originated from. If you have an issue, try eliminating areas of the code and then running it. Internal Apple forums or documentation could prove to be useful too.

When it comes to app testing and development, there is no such thing as too many cooks spoiling the broth. Instead, the app has to be tested in simulated settings to ensure that it works and the interface looks amazing. Best testing is done when there are more users. In the case of app testing, it is clear that the more, the merrier ( or rather technologically advanced app) will result. Another very important point is that external testers provide an unbiased view of the entire situation and you can access the unique identification number of each device.

Release the Project

You need to launch the app finally. This involves creating the own distribution build. Then, you need to connect with the iTunes dashboard and manage your applications. You can fill out forms providing app description, support site, category, copyright, contact emails, and keyword. iTunes artwork should be ready. The next stage in the process is to upload your app. You need to install the Application loader tool and launch it, which will then verify the iTunes Connect account.

Promoting your app is one thing; waiting for its review is another. When the application status changes to review and fails the initial gamut of tests, rejection emails will be passed to you and suggestions are given for improvement. In case Apple approves your app, you can go home ‘happy, secure in the knowledge that your app is ready for sale. You also need to promote your app and spread the word using social media. Use YouTube videos as well as get other people to talk about the particular app.

Free copies can also be sent to the reviewers writing about the app. Another key indicator of how an app will fare is its sales. You need to log in every day and check, sales and marketing as well as countries where the sale is being made. Apple will also send the latest sales data and it can be downloaded for the records.

Prerequisites for iPhone app development and training

There should be prior programming experience and deep comprehension of programming concepts such as variables, if statements, functions, classes and loops. You also need to access Mac computers with the latest OS. This is a technical requirement.

Decoding Xcode

This is the tool which serves as a medium for writing apps. One becomes familiar with project structure in Xcode and navigates between the components. You should be able to create a project in Xcode, identify key functions of the files, open and switch between files within the project and run the app through simulations. Pre-Configuration of interfaces and easy coding are some of the advantages of iPhone apps training. Product name refers to a particular title. Other values which are important for the dialog include organization name and identifier, bundle identifier, language, and devices.

The universal app is one that uses core data and runs on iPhone and iPad. You need to also select the location and save the project. In fresh workspace windows, new projects can be opened through Xcode. Xcode has everything you could possibly require to build an application. Xcode includes everything needed to create the app, build and run it without any bugs.

The next obvious step to take is to set up a Single View Application template without additional configuration and to run the app in the simulator.

Coding iPhone apps is easy. A fast job is possible through the Swift Code and iOS development basics.

What You Need to Known for iPhone Apps Training

You should primarily know how to read and write the Swift code and write Xcode 7. Constructing app interfaces and using an auto layer to position user elements is also imperative. User interaction should also be handles and multiple screens are there to navigate between them. Those who are keen to take part in iPhone apps training should also use interface elements such as buttons, table, and scroll views. Everything from knowing how to play sounds and use the timer to save data is a prerequisite for iPhone Apps training. You should also know how to parse data feeds to display in the app and manage varied orientations as well as expressing conditional logic within the app. Debugging and troubleshooting codes is also part and parcel of the programming process. Towards the close, you will become less of a beginner and more of an expert. This is what makes iPhone apps so unique. Although the learning curve is moderately tough, acquiring iPhone apps training is completely beneficial.

Who Should Learn?

Developers would really benefit from iPhone Apps training in how to create great mobile applications of iOS. Another key beneficiary could be students and users. Almost anyone can acquire iPhone Apps training because it needs very little programming experience.

Features of a Great iPhone Mobile App

iPhone is a unique device and developing apps for it requires special expertise to some extent also. Hardware, as well as software systems, open up a world of possibilities when it comes to iPhone Apps training users how to utilize iPhone apps. The combination of hardware and software offers design advantages few other conventional devices can replicate

• One App, Multi-Finger Gestures
  Applications respond to finger gestures. So clicking a mouse will not get you very far. Designing apps with single finger tap almost as if they were computer based apps is counterproductive. multi-finger gestures will lead to the design of more comprehensive user experience
• Detecting Orientation, on the Move
  iPhone has an accelerometer. Apps need to keep up with this as well as changing display for different orientations
• Unique Keyboards, Multiple Split Views
  The Split view can be used on the iPad to display more than a single view on the screen at a given time. Evert device provides a special keyboard associated with unique tasks such as numeric keyboards appearing on the numbers app

iPhone Apps: Special Advantage, General Features

Users can receive as well as send emails and browse online using iPhone apps. These applications can also be used for syncing contacts, calendars, and notes online. Even if you want to download content from the Apple stores, these apps can help. Apps go an extra mile without storing lots of data.

• TV/ Projection Connections
• Users can also connect the iPhone or iPad to HDTV or projection system for displaying content to a wider audience. Airplay and Apple TV ensures that physical connections are not required
• A System Environment that is Consistent

The Home button leads to apps being closed. Volume button takes care of audiences. iOS apps can exist alongside web services and apps created on HTML5. With excellent photos and videos, iPhone app can be set to 24 bits including an 8-bit alpha channel to display how the color of the pixel can be merged with another.
