What is the difference between window and view in iphone

Some people are going to take advantage of the new Focus feature. Other people are just going to miss or dismiss the new features. Some people will simply dismiss iOS 15 altogether. It seems like a small change, but it actually says a lot about the current state of iOS. Apple considers iOS as a mature platform.

Apps should potentially work on older iOS versions for longer. But Apple has people who pre-ordered the iPhone 13 and will get iOS Image Credits: Apple. Chances are you spend a lot of time with your phone, and your device requires a lot of attention from you. With this new feature, it reverses the balance and puts you back in charge. But you can now create additional Focuses. Each Focus is customizable to your needs and you can create new Focuses from scratch. When you turn on a specific Focus, it basically blocks notifications by default.

You can then add people and apps so that notifications from those people and apps still go through. App developers can also mark a notification as time sensitive so that it always goes through.

There are three more settings that you can activate. First, you can optionally share that your notifications are currently silenced in Messages and compatible third-party apps. Second, you can hide home screen pages altogether.

Third, you can hide notifications from the lock screen and hide badges from the home screen. You can work with threads by submitting work items to the threadpool with RunAsync. You can use a timer to submit a work item with CreateTimer and create a repeating work item with CreatePeriodicTimer.

Submit a work item to the thread pool Use a timer to submit a work item Create a periodic work item Best practices for using the thread pool. Asynchronous programming. Avoid threading complexity by taking advantage of asynchronous programming patterns to keep the UI thread responsive. The use of threading is required to create your own asynchronous classes. Some built-in classes are asynchronous.

The use of threading is required is required to create your own asynchronous classes. You can use asynchronous patterns to avoid blocking the main thread when you create your own APIs, for example, using async and await in C and Visual Basic.

You can use the asynchronous built-in APIs which end in the word Async. List view optimization. Built-in patterns to aid with optimizing lists of data, which often have poor performance when large amounts of data need to be shown. The ViewHolder design pattern is used to avoid multiple view lookups, which allows you to use reusable UI elements.

A range of optimizations can be made to improve the performance of UITableView , nothing is built-in. You can use the ListView and GridView controls which provide UI virtualization out-of-box, providing a smooth panning and scrolling experience and a faster startup time.

You can also implement IList and INotifyCollectionChanged in your data source, providing data virtualization and further improving performance. In-app purchases. Platform features that allow users to make purchases in your apps. In-app billing is provided by Google Services. Products are added to the Google Play Developer Console. In-app purchases are implemented with the Google Play Billing Library.

Products are added to iTunes Connect. In-app purchases are implemented using the StoreKit framework. You create in-app product purchases for your app by adding them to your app and submitting them to the Store. You use the CurrentApp class to define in-app purchases. You use CurrentApp. Enable in-app product purchases. Consumable in-app purchases. In-app products which can be purchased, used and then purchased again.

Consumable purchases are enabled by making a regular purchase and then consuming it with consumePurchase , enabling it to be purchased, used, and then purchased again. Consumable products are defined as consumable products in iTunes Connect. You can support consumables by defining their product type as Consumable when you submit them to the Store. You then call CurrentApp. ReportConsumableFulfillmentAsync after a consumable purchase has been made to allow the customer to access it.

Enable consumable in-app purchases. Testing in-app purchases. Enabling you to test your in-app purchase code without putting your app in the Store.

Enabling you to easily limit content or remove advertising based on a trial version of an app. Google Play doesn't officially support app trials. Trials or removing advertising is achieved by creating an in-app purchase and taking the appropriate code path when confirming the purchase was successful. The App Store doesn't officially support app trials. You can offer a free trial version of your app by using the 'Free Trial' option when submitting your app to the Store. You can then use LicenseInformation.

IsTrial to check the trial status of the app and present different code paths accordingly. You can register for the LicenseChanged event to be notified when the user changes the trial status while the app is running.

Exclude or limit features in a trial version. Adaptive UI: flexible layouts. Supporting different screen sizes with a flexible height and width. Flexible layouts can be achieved using the adaptive model with universal Storyboards, making use of Auto Layout with constraints and traits such as horizontalSizeClass and displayScale which are applied to view controllers. You can create a fluid layout using layout properties and panels with a combination of fixed and dynamic sizing.

Adaptive UI: tailored layouts. Supporting different screen sizes with separate targeted layouts. Providing alternative layout files for different screen configurations in the resources directory using configuration qualifiers such as small , large , ldpi , and hdpi allows you to target custom layouts to screens of varying size and density.

Define a separate iPhone and iPad Storyboard to tailor layouts to different device families in a universal app. You can build a tailored layout by defining different XAML markup files per device family. Define layouts with XAML - tailored layouts. Adaptive UI: responsive layouts. Responding to changes in screen size, such as rotation, or a change in the size of a window. Use of flexible layouts with LinearLayout and RelativeLayout , or providing alternative layout files for different orientations enable responsive layouts.

When the size or traits of a view change, the constraints specified in storyboards are applied. You can easily reflow, reposition, resize, reveal, or replace sections of your UI at runtime in response to window size changes using VisualState , the VisualStateManager and AdaptiveTrigger. Supporting different device capabilities. Take advantage of advanced hardware features while still supporting devices without them.

Testing for device features at runtime using PackageManager. There is no single check you can perform at runtime to test for device features, you test for each feature in a specific way to decide if hardware specific code can be run.

You can add platform extension SDKs to your package to target additional functionality found in different device families including phone, desktop, and IoT. You use the ApiInformation API to test for the presence of types and members at runtime, and can call those types and members only if they're present.

Testing for the API level at runtime can be done using Build. Standard runtime checks are used to find out if APIs are available, such as the class method to check if a class exists and respondsToSelector: to check for methods on classes.

You can use ApiInformation. You also use the ApiInformation API to test for the presence of types and members at runtime, and can call those types and members only if they're present. Tiles and badges. Present updates to users on the home screen.

App Widgets are views on your application that can be embedded into the home screen and can receive periodic updates. No badge system exists on Android. No identical system to tiles exists. You can also add a badge to your icon with a number which can change in response to local or remote notifications.

There is no tiles system. Your app has a tile which can be pinned to the start screen and is used to display your choice of text, images, and a badge with glyphs and numbers. You can update the content of tiles from the app; via push notifications or at predefined schedules. Tiles can be adaptive, and can change according to where they are being displayed. Create tiles Create adaptive tiles Choose a notification delivery method Guidelines for tiles and badges.

Displaying notifications. Types of notifications that can be displayed. Notifications can be shown in the notification area and notification drawer , heads-up notifications present a notification in a small floating window. Notifications can have actions added to them by defining a PendingIntent. Pop-up notifications appear as banners or alerts. You can create adaptive pop-up notifications called toast notifications.

You can define toasts in XML with visual content, actions which can be buttons, or inputs and audio. Adaptive and interactive toast notifications Choose a notification delivery method Guidelines for toast notifications. Scheduling local notifications. Local notifications sent by your app at a scheduled time. Notifications and actions are defined using a NotificationCompat. Builder and can be scheduled and handled in-app using AlarmManager and BroadcastReceiver.

You can schedule a toast notification using ScheduledToastNotification. You can send a tile notification from your app using the TileNotification class , or schedule a tile notification with ScheduledTileNotification.

Adaptive and interactive toast notifications Send a local tile notification Sending push notifications. A notification sent from a push notification server and optionally handled in-app. Google Cloud Messaging provides push notification support for Android.

Using an intent such as MediaStore. Using the android. MediaRecorder APIs can be used to capture audio. The AVAudioRecorder class enables audio recording. You can interact with the camera at a low level, and capture audio with classes in Windows. The MediaPlayer and AudioManager classes are used to play audio and video files. You can use the MediaSource class , MediaElement , and MediaPlayer classes to play back audio and video from sources such as local and remote files. Media playback with MediaSource.

Editing media. Composing new media files from existing recordings and applying special effects. Low level classes such as MediaCodec , MediaMuxer , and android. You can use the Windows.

You are able to add video and image overlays, combine video clips, add background audio, and apply audio and video effects. Media compositions and editing. Detect device movement, position and environmental properties.

The sensor framework is used to access hardware and software sensors with classes such as SensorManager and SensorEvent.

The Core Motion framework is used to access raw and processed sensor data. You can use classes in Windows. Sensors to access sensor readings and events triggered when new reading data is received from the sensor.

Finding the device's current location and tracking changes. The Google Play services location APIs provide high-level access to the last known location with the fused location provider using the getLastLocation and requestLocationUpdates methods.

You can point your camera at any text, be it handwritten or typed, and Live Text will pull that information into copyable text. Siri also now processes speech entirely on device, allowing theoretically more secure and faster interactions, as well as offline Siri commands for the first time. Those are obviously limited in what they can do, but you can kick your phone into airplane mode and still accomplish basic tasks like opening apps, setting timers, and toggling settings.

The new subscription service is bundled with existing paid iCloud storage subscriptions, and adds a few new features. The biggest feature though, is Private Relay, a VPN-style service that aims to mask your internet traffic from your iPhone. Second is that it only works in Safari, not other apps or browsers. Apple Maps is rolling out a very fancy looking new 3D map. Despite the Dark Sky purchase, though, Apple is still relying on a combination of first-party data, The Weather Channel, and other third-party sources for its forecasts even though Dark Sky produced its own weather data API in the past.

Both the Notes and Reminders have a newly added tag system, along with smart folders that can automatically pull in those notes and reminders using those tags. The links and photo aspects are the most useful, surfacing old pictures that friends and family members had sent me over the years.

As I noted back in my beta hands-on over the summer, iPadOS 15 is virtually identical to iOS 15, except for a few iPad-specific improvements. Two mostly welcome changes are the addition of the widget and App Library system added to the iPhone in iOS Apple is offering an even bigger widget size option for the iPad, though, which takes up an entire third of the screen in a four-icon by two-icon grid and is physically about the same size as an iPhone 12 when viewed on a So far, the best implementation is the Photos app, which can act as a sizable photo frame on your home screen now.

As a side effect of the expanded widget support, though, Apple bewilderingly reduced the number of icons you can have on an iPad home screen in iPadOS On a
