【Beta】 6月22日
1. ** Pasted from *** 提示
苹果强化了对系统剪切板内容访问的提示，适度减少访问频次吧。
不过在大家都玩口令的年代，这很难控制住...
2. 系统输入法（中文输入法），某些情况下输出字符与点击字符不对应。
最初升级完成时偶现，暂不能复现。
3. 子类覆盖父类的属性
以前的版本只会提示警告⚠️ ，iOS 14上开始直接报错了，编译会无法通过。
*.h
@property (nonatomic, assign, readonly, getter=isEditing) BOOL editing;
*.m
Auto property synthesis will not synthesize property 'editing'; it will be implemented by its superclass, use @dynamic to acknowledge intention
- 原因 自动属性合成机制在覆盖父类属性时罢工，手动修复即可。
@synthesize editing = _editing;
4. UIPageControl 子视图层级变更 及 新增 API
自定义页码标签形态的需求，如： 长条形状 或 其它
iOS 14 UIPageControl 子视图层级.png
- 曾经的方案是遍历
UIPageControl子视图，添加UIImageView来达到定制目的。
if ([self.subviews count] == 0) {
UIImageView * imageItem = [[UIImageView alloc] init];
[self addSubview:imageItem];
}
- 新增API
看来苹果终于是注意到产品汪们的定制需求了，然并卵
看似新增的API表面上满足了定制需求，但是经过尝试仅有一条是有用的。
preferredIndicatorImage，并且需要搭配pageIndicatorTintColor、currentPageIndicatorTintColor才能完成有限的简单定制。
如果产品汪们需要通过间距或者其它自定义图片来提现设计感，那么就实现不了了。
typedef NS_ENUM(NSInteger, UIPageControlInteractionState) {
/// The default interaction state, where no interaction has occured.
UIPageControlInteractionStateNone = 0,
/// The interaction state for which the page was changed via a single, discrete interaction.
UIPageControlInteractionStateDiscrete = 1,
/// The interaction state for which the page was changed via a continuous interaction.
UIPageControlInteractionStateContinuous = 2,
} API_AVAILABLE(ios(14.0));
typedef NS_ENUM(NSInteger, UIPageControlBackgroundStyle) {
/// The default background style that adapts based on the current interaction state.
UIPageControlBackgroundStyleAutomatic = 0,
/// The background style that shows a full background regardless of the interaction
UIPageControlBackgroundStyleProminent = 1,
/// The background style that shows a minimal background regardless of the interaction
UIPageControlBackgroundStyleMinimal = 2,
} API_AVAILABLE(ios(14.0));
/// The preferred background style. Default is UIPageControlBackgroundStyleAutomatic on iOS, and UIPageControlBackgroundStyleProminent on tvOS.
@property (nonatomic, assign) UIPageControlBackgroundStyle backgroundStyle API_AVAILABLE(ios(14.0));
/// Returns YES if the continuous interaction is enabled, NO otherwise. Default is YES.
@property (nonatomic, assign) BOOL allowsContinuousInteraction API_AVAILABLE(ios(14.0));
/// The preferred image for indicators. Symbol images are recommended. Default is nil.
@property (nonatomic, strong, nullable) UIImage *preferredIndicatorImage API_AVAILABLE(ios(14.0));
/*!
* @abstract Returns the override indicator image for the specific page, nil if no override image was set.
* @param page Must be in the range of 0..numberOfPages
*/
- (nullable UIImage *)indicatorImageForPage:(NSInteger)page API_AVAILABLE(ios(14.0));
/*!
* @abstract Override the indicator image for a specific page. Symbol images are recommended.
* @param image The image for the indicator. Resets to the default if image is nil.
* @param page Must be in the range of 0..numberOfPages
*/
- (void)setIndicatorImage:(nullable UIImage *)image forPage:(NSInteger)page API_AVAILABLE(ios(14.0));
- 老调重弹 为了满足别出心裁的设计，仍然需要通过遍历的方法。
//遍历到如下层级 并添加 UIImageView 来完成定制
UIPageControlindicatorContentView
5. Xcode 12 beta 真机调试崩溃 TXIJKSDLGLView 相关
模拟器 及 真机非调试运行，无崩溃。

6. UITableViewCell 层级调整 强制要求
自定义子视图，曾经可以添加在
self、contentView上均可。
以后需要注意了，必须按照苹果的规范。
// Custom subviews should be added to the content view.
@property (nonatomic, readonly, strong) UIView *contentView;
- 影响： 不添加在
contentView上的子视图，存在点击事件无法响应以及视图被系统默认高亮效果覆盖的问题。
7. YYTextView 拼音输入法 联想词功能失效
模拟器看起来正常
真机上目前是必现的
这里要说声抱歉咯，如果曾经有人参照我的方法来解决不释放的问题。那么记得改回来哦
改回来，你就会发现正常了 🤣
YYTextView.m
line: 3268
#pragma mark - @protocol UIKeyInput
`复原此方法 ！！！`
- (BOOL)hasText {
//return NO;
return _innerText.length > 0;
}
8. 腾讯短视频 SDK 需要等待适配
TXVideoEditer
视频文件裁剪功能异常，视频音频数据会被破坏从而造成收音机噪声的效果。
9. Xcode12 beta 旧项目创建 Widget 扩展项目报错
注意两点：
- Build System:
Legacy Build System (Depercate)-->New Build System (Default)- Per-User Workspace Settings:
Build System: Use Shared Setting

10. 系统原生导航栏按钮长按触发 _UIContextMenuContainerView
iOS 14 UIMenu新增能力，苹果不地道的没有留属性控制。
