This session focuses on the 3D touch feature, which is roughly described:</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-enhanced Force Touch (pressure Touch) technology, which was previously applied to Apple Watch</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-depending on the dynamics, this leads to a more diverse user experience. For example, pressing the fast-forward button will make fast-forward faster, with a touch of force instead of a long-press drag-and-drop option, the user can adjust the application interface when pressing the screen, etc.</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-on the basis of click, swipe, and zoom, Two new gestures have been introduced for the iphone: preview (Peek) and tap (Pop). This feature allows pictures, messages, messages, and other content to float to the surface of the screen while making other content appear to be bokeh. Content highlighting effect varies with finger press force</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-with a capacitive sensor integrated with the retina screen, you can detect finger force size by detecting the distance between the glass and the backlight</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-currently supports 3D touch devices only iphone 6s and iphone 6s Plus, even with the powerful Apple Pencil such as ipad Pro, is not supported. however, following Apple's usual approach, the new enhanced version of the ipad Pro should integrate the feature</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-the 3D Touch feature is turned on by default, but the user can also turn it off in system settings (Settings > General > Accessibility > 3D touch)</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-minimum system requirements for 3D touch are IOS 9, and developers need to use at least Xcode 7 GM, the latest version of Xcode 7.1 beta</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;"></span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">More closely related to the Developer:</span></p></p><p align="left"><p align="left"><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-pressure sensitivity: pressure sensitivity that can be used in conjunction with painting and other authoring software, such as changing the stroke/line thickness values based on the size of the Pressure. Some new properties are added primarily for the Uitouch class, such as Estimatedproperties (touch properties), updatedproperties (touch object update), and so on, and the new API is mainly focused on the precision part of obtaining x/y coordinates, such as- Preciselocationinview:,-precisepreviouslocationinview: etc., There is a need to pay special attention to the uiforcetouchcapability, the function before the use of functional availability testing must be</span></p></p><p align="left"><p align="left"><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-Peek and Pop: the newly introduced gesture, which allows the user to preview the content and even manipulate it. such as the document preview shortcut in mac, the snapshot content in the browser, etc.</span></p></p><p align="left"><p align="left"><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-quick actions: Shortcut menu, full name is Home screen quick actions, similar to the right-click menu in the computer, mainly for the quick operation, this from its API name can be seen: Uiapplicationshortcutitem. As Apple describes it, it allows users to use fewer steps to get the most out of their most commonly used operations, and concludes by saying "one-click operation." This section is also divided into 2 types: static & dynamic, where static mode is configured in info.plist, dynamic code-level dynamic configuration processing through APIs such as Uiapplicationshortcutitem. The system defaults to show static Actions. If the app is never opened after installation, only static actions will be shown by default, and dynamic actions will only appear after at least one full boot. This section will be followed by a special Introduction.</span></p></p><p style="text-align: center;"><p style="text-align: center;"><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;"></span></p></p><p style="text-align: center;" align="left"><p style="text-align: center;" align="left"><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">Figure 1 Quick Actions</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">Small details</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-in a real-time device that supports 3D touch, the system calls the Touchesmoved:api method when the touch pressure Changes. One problem with this is that the x/y coordinates may not have changed in the touch move event ~ ~ ~ The best compatible preparation in the recommended app</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-app refresh rate will change after IPad Pro is paired with Apple Pencil. For example, the original 20/s, paired with Apple pencil, will become 40/s. The increase in refresh rate may be more accurate in order to obtain x/y coordinates, but will have an impact on app UI updates, such as frequent build/delete of memory Objects.</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-currently 3D Touch can only be tested in a real-machine device and cannot be debugged/tested temporarily in the simulator ~ ~</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-there have been other ways for developers to emulate the Quick actions effect in the low version (below IOS 9) system, which is interesting to search</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;"></span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">Reference links</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-https://developer.apple.com/ios/3d-touch/</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-https://developer.apple.com/library/prerelease/ios/documentation/UserExperience/Conceptual/Adopting3DTouchOniPhone/</span></p></p><p><p><span style="font-family: ‘Microsoft YaHei‘; font-size: 14px;">-https://developer.apple.com/library/prerelease/ios/releasenotes/General/RN-iOSSDK-9.1/index.html#//apple_ref/ doc/uid/tp40016570</span></p></p><p><p></p></p><p><p></p></p><p style="text-align: center;"><p style="text-align: center;"><span style="color: #ff0000; font-family: ‘Microsoft YaHei‘; font-size: 14px;">All rights reserved, reprint must indicate the author (jintian) and original source (original).</span></p></p><p><p>IOS 9 3D Touch</p></p></span>
