New Features in iOS & iPadOS 15 beta

• For apps compiled against the iOS 15 beta SDK, key commands no longer intercept text input and text editing commands while typing into text views and text fields. For example, pressing the Delete key always deletes a character and doesn’t trigger a Delete key command if one is present. To have a key command intercept text input, set the wantsPriorityOverSystemBehavior property to true on the key command. This is also required to have key commands take priority over focus keyboard navigation commands, such as arrow and tab key presses. (55118263)
  针对iOS 15 beta SDK编译的应用程序，关键命令不再拦截文本输入和文本编辑命令，而输入文本视图和文本字段。例如，按下Delete键总是删除一个字符，并且不会触发Delete键命令(如果存在的话)。要获得密钥命令拦截文本输入，在密钥命令上设置wantsPriorityOverSystemBehavior属性为true。这也要求按键命令优先于焦点键盘导航命令，如箭头和tab键按下。
• In iOS 14 and iPadOS 14 and earlier, when autocorrectionType is set to UITextAutocorrectionTypeNo, the QuickType bar is disabled. For apps linked against iOS 15 and iPadOS 15 or later, the QuickType bar is enabled, and shows spellchecking candidates. If the new behavior isn’t desirable for your use case, set spellCheckingType to UITextSpellCheckingTypeNo to hide the QuickType bar. (68874861)
  在iOS 14和iPadOS 14及以前版本中，当“autocorrectionType”设置为“UITextAutocorrectionTypeNo”时，QuickType栏被禁用。对于iOS 15和iPadOS 15或更高版本的应用程序，QuickType栏是启用的，并显示拼写检查候选。如果新的行为不适合你的用例，将spellCheckingType设置为UITextSpellCheckingTypeNo以隐藏QuickType栏。
• When compiling with the iOS 15 beta SDK, several key window related properties, methods, and notifications change behavior:
  当使用iOS 15 beta SDK编译时，几个关键窗口相关的属性、方法和通知改变行为:

1. isKeyWindow returns true if the window is key in its scene instead of the app.
   isKeyWindow返回true如果窗口在它的场景中是关键而不是应用程序。
2. becomeKeyWindow is called when the window becomes key in its scene instead of the app.
   当窗口成为场景中的关键而不是应用程序时，调用becomeKeyWindow。
3. didBecomeKeyNotification posts when the window becomes key in its scene instead of the app.
   当窗口在它的场景中成为关键而不是应用程序时，didBecomeKeyNotification发布
4. resignKeyWindow is called when the window resigns key window status in its scene instead of the app.
   当窗口退出场景中的关键窗口状态而不是应用程序时调用resignKeyWindow。
5. didResignKeyNotification posts when the window resigns key window status in its scene instead of the app. (72873846)
   当窗口在其场景中退出关键窗口状态而不是应用程序时，didResignKeyNotification将发布。

• Support for cleartext HTTP URL schemes for Proxy Automatic Configuration (PAC) is now deprecated. Use only HTTPS URL schemes for PAC. This affects all PAC configurations, including, but not limited to, configurations set via Settings, System Preferences, profiles, and URLSession APIs such as connectionProxyDictionary and CFNetworkExecuteProxyAutoConfigurationURL(:::??. If you configure a cleartext HTTP PAC URL, the system may upgrade it to HTTPS during PAC file loads. Web Proxy Auto-Discovery (WPAD) Protocol via DNS isn’t affected. Dynamic Host Configuration Protocol (DHCP) Option 252 WPAD may attempt to upgrade cleartext HTTP URLs to HTTPS during PAC file loads. (61981845)
