iOS13暗黑模式适配

一、颜色适配

  • iOS13 之前 UIColor只能表示一种颜色,而从 iOS13 开始UIColor是一个动态的颜色,在Light Mode和Dark Mode可以分别设置不同的颜色。
  • iOS13系统提供了一些动态颜色
@property (class, nonatomic, readonly) UIColor *systemBrownColor        API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *systemIndigoColor       API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *systemGray2Color        API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *systemGray3Color        API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *systemGray4Color        API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *systemGray5Color        API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *systemGray6Color        API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *labelColor              API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *secondaryLabelColor     API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *tertiaryLabelColor      API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *quaternaryLabelColor    API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *linkColor               API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *placeholderTextColor    API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *separatorColor          API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *opaqueSeparatorColor    API_AVAILABLE(ios(13.0), tvos(13.0)) API_UNAVAILABLE(watchos);
@property (class, nonatomic, readonly) UIColor *systemBackgroundColor                   API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *secondarySystemBackgroundColor          API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *tertiarySystemBackgroundColor           API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *systemGroupedBackgroundColor            API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *secondarySystemGroupedBackgroundColor   API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *tertiarySystemGroupedBackgroundColor    API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *systemFillColor                         API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *secondarySystemFillColor                API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *tertiarySystemFillColor                 API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);
@property (class, nonatomic, readonly) UIColor *quaternarySystemFillColor               API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(tvos, watchos);

直接设置颜色即可:

[self.view setBackgroundColor:[UIColor systemBackgroundColor]];
[self.titleLabel setTextColor:[UIColor labelColor]];
[self.detailLabel setTextColor:[UIColor placeholderTextColor]];
  • 根据当前显示模式动态配色

view.backgroundColor = [UIClolor generateDynamicColor:UIColor.blackColor darkColor:UIColor.redColor] ;

二、图片适配
图片适配需要提供两套相同名字的图片,分别对应any-dark位置,如下图所示;
注意:图片为同名,如"[email protected]"和"[email protected]",设置后图片会根据当前显示模式自动适配

UIImage *icon = [UIImage imageNamed:@"icon"];
