一、顏色適配

• iOS13 之前 UIColor只能表示一種顏色，而從 iOS13 開(kāi)始UIColor是一個(gè)動(dòng)態(tài)的顏色，在Light Mode和Dark Mode可以分別設(shè)置不同的顏色。
• iOS13系統(tǒng)提供了一些動(dòng)態(tài)顏色

@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);

直接設(shè)置顏色即可：

[self.view setBackgroundColor:[UIColor systemBackgroundColor]];
[self.titleLabel setTextColor:[UIColor labelColor]];
[self.detailLabel setTextColor:[UIColor placeholderTextColor]];

• 根據(jù)當(dāng)前顯示模式動(dòng)態(tài)配色

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

二、圖片適配
圖片適配需要提供兩套相同名字的圖片，分別對(duì)應(yīng)any-dark位置，如下圖所示；
注意：圖片為同名，如"icon@2x.png"和"icon@2x-1.png",設(shè)置后圖片會(huì)根據(jù)當(dāng)前顯示模式自動(dòng)適配

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