Although this document has been reviewed for technical accuracy, it is not final. This Apple confidential information is for use only by registered members of the applicable Apple Developer program. Apple is supplying this confidential information to help you plan for the adoption of the technologies and programming interfaces described herein. This information is subject to change, and software implemented according to this document should be tested with final operating system software and final documentation. Newer versions of this document may be provided with future seeds of the API or technology. Notifications are concise, unobtrusive messages that appear in the top-right corner of the screen, alerting Mac users about a new message or a completed task. As a web developer, you can configure your website to send notifications to Mac users, even if you don’t have a native Cocoa app. Figure I-1 Notifications in Notification Center There are two kinds of notifications for websites: ● Safari Push Notifications, which is an Apple-exclusive technology and triggered remotely using Apple Push Notification service (APNs). ● Local Notifications, which are specified by a W3C standard and triggered locally using JavaScript. 2013-08-20 | Copyright © 2013 Apple Inc. All Rights Reserved. Apple Confidential Information. 4 About Notifications for Websites At a Glance Note: This document pertains to OS X only. Notifications for websites do not appear on iOS. At a Glance This document explains the key concepts of notifications for websites and how to implement them in your ecosystem. Users Control Their Notifications Review the preferences available to users to better understand how to implement your notification service. Relevant Chapter: “Understanding the User Experience” (page 7) Safari Push Notifications Are Deployed from Your Server In OS X v10.9 and later, you can send push notifications to your website users. Safari doesn’t need to be open for the notification to appear, and your visitors have control over their notification settings on a per-website basis. Relevant Chapter: “Configuring Safari Push Notifications” (page 12) Local Notifications Are Invoked with JavaScript In OS X v10.8 and later, you can tap into Notification Center through a JavaScript API. After visitors grant permission to receive local notifications, you can trigger notifications to appear as long as the webpage remains in an open tab. Relevant Chapter: “Configuring Local Notifications” (page 26) See Also ● WWDC 2013: Implementing OS X Push Notifications for Websites shows best practices for implementing push notifications for websites. ● Local and Push Notification Programming Guide describes how to send push notifications to iOS and OS X apps. 2013-08-20 | Copyright © 2013 Apple Inc. All Rights Reserved.

All Rights Reserved. Apple Confidential Information. 6 Understanding the User Experience To best serve notifications to your users, you must first understand how OS X displays notifications. In this chapter, you learn the difference between local notifications and push notifications for websites, how users grant permission for websites to display notifications, and how users manage their notification preferences. Local Versus Website Push Notifications Starting in OS X v10.8, Safari users can allow websites to display banners and alerts in Notification Center. Through a JavaScript API, you can create notifications that appear and behave like notifications from native Cocoa apps, as shown in Figure 1-1 and Figure 1-2. Figure 1-1 A banner showing a local notification Figure 1-2 A local notification in Notification Center Because local notifications are controlled entirely by JavaScript, the user must have your website open in a Safari window (or tab) for your notification to appear. Safari can be minimized or hidden, or your website could be loaded in an inactive tab, but it must be open to run the JavaScript that creates the notification. 2013-08-20 | Copyright © 2013 Apple Inc. All Rights Reserved. Apple Confidential Information. 7 Understanding the User Experience Local Versus Website Push Notifications Local notifications display the Safari icon, and appear under the Safari section in Notification Center. The Safari section in Notification Center is where local notifications from all websites appear. The notification title, domain, and body are shown. Because local notifications appear as coming from Safari, rather than from your website directly, the user’s notification preferences for Safari are applied. Push notifications are similar to local notifications. They exhibit the same appearance, except that they have their own icon and section in Notification Center, as shown in Figure 1-3 and Figure 1-4. Figure 1-3 A banner showing a push notification sent from a web server Figure 1-4 A push notification in Notification Center Unlike local notifications, push notifications don’t display the website domain, because the icon makes it clear which website it represents. More importantly, push notifications can be received even when Safari is closed. 2013-08-20 | Copyright © 2013 Apple Inc. All Rights Reserved. Apple Confidential Information. 8 Understanding the User Experience Opting In to Notifications Note: If you already have an OS X app, you should push notifications through your app. To avoid sending duplicate notifications to users who accept notifications from both your app and website, you need to add extra logic in your server-side scripts. See “Configuring Your Web Service Endpoints” (page 20). Opting In to Notifications Users must opt in to receive notifications. The opt-in process only occurs once per domain. The presentation of asking for permission is identical for all website notifications. In fact, the permission policy that a user chooses for push notifications applies to local notifications. Compare the appearance of requesting both kinds of notifications in Figure 1-5 and Figure 1-6. Figure 1-5 Requesting to display local notifications Figure 1-6 Requesting to display push notifications As you can see, the permission sheets for local and push notifications look very similar. The request appears only once; after a user sets the permission level, the preference is saved. 2013-08-20 | Copyright © 2013 Apple Inc. All Rights Reserved. Apple Confidential Information. 9 Understanding the User Experience Users Can Change Their Notification Preferences Remember: Allowing or denying a request for push notifications sets the same permission level for local notifications as well. Users Can Change Their Notification Preferences Users can adjust their notification preferences in Safari preferences and System Preferences. In Safari preferences, users can choose to allow or deny notifications from websites on a per-domain basis by selecting Notifications, as shown in Figure 1-7. In the Notifications pane, users can grant permission for some websites to send notifications while denying permission to others. Figure 1-7 Controlling which websites have authorization to send notifications 2013-08-20 | Copyright © 2013 Apple Inc.

Go to the iDevice FORUM, click HERE To find Apps that are free for a short time, click these 2 icons: Introducing the iWatch Click to see the video New iPhone Lock screen bypass discovered Here's how to protect against it! By Rene Ritchie, Monday, Jun 9, 2014 16 A new iOS 7.1.1 iPhone Lock screen bypass has been discovered. Lock screen bypasses in and of themselves aren't new — trying to protect a phone while also allowing access to convenient features results is an incredible tension — but this one can provide access to an app, which makes it one of the most serious to date. It does require physical access to your iPhone, but if you do lose possession, here's how the bypass works and, more importantly, how you can protect yourself from it. Note: iMore tested the exploit and its scope before reporting on it. We were able to duplicate it but also get a sense of its ramifications and limitations. First, in order to get around the passcode lock, this bypass requires that the iPhone be placed into Airplane mode, and that a missed phone call notification be present. When those conditions are met, tapping or swiping the missed call notification will cause a Settings popup to appear on top of whatever app was last active (in the foreground) on the iPhone prior to it being locked. Dismiss the popup and you have access to the app.

  • For Iphone & Ipad
    iOS Tips & Tricks For iPhone & iPad General Tips & Tricks Notification Center: Swipe down from the top to open the Notification Center. In the iOS 7 update, the notifications are broken up into today, all and missed. Today pulls information from your calendar to give you a daily briefing on the day's activities, and Missed gives you access to missed calls. Control Center: Swipe up from the bottom of the screen from anywhere in iOS and you get the phone's quick settings panel. There are five buttons that allow you to put your device in airplane mode, disable Wi-Fi, disable Bluetooth, turn on/off Do Not Disturb and adjust portrait lock. Brightness settings can be toggled with a slider, followed by the ability to control your music by skipping songs, pressing play/pause and adjusting the volume. AirDrop and AirPlay are found underneath. Apple has also added a torch (flashlight) and next to that is the quick button to the alarm clock, calendar and camera buttons. Spotlight Search: Just swipe down in the middle of any home page and you’ll find Spotlight Search is ready to go. Use it to find whatever you need on your iPhone. It’s a good way to quick launch an app, find an email, or a contact, but it no longer searches the Web. You can swipe up or tap twice to get rid of the search. Swipe to Go Back: You can just swipe from the left side of the screen in a supported app to jump back to what you were doing.
