> If you want to implement night mode in Swift project without import Objective-C code. [NightNight](https://github.com/Draveness/NightNight)

 is the Swift version which does the same work.



# How To Get Started



DKNightVersion supports multiple methods for installing the library in a project.



## Installation with CocoaPods



[CocoaPods](https://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like DKNightVersion in your projects. See the [Get Started section](https://cocoapods.org/#get_started) for more details.



### Podfile



To integrate DKNightVersion into your Xcode project using CocoaPods, specify it in your `Podfile`:



```shell

pod "DKNightVersion"

```



Then, run the following command:



```shell

$ pod install

```



### Import



Import DKNightVersion header file



```objectivec

#import 

```



## Usage



Checkout `DKColorTable.txt` file in your project, which locates in `Pods/DKNightVersion/Resources/DKNightVersion.txt`.

```

NORMAL   NIGHT

#ffffff  #343434 BG

#aaaaaa  #313131 SEP

```



> You can also create another colour table file, and specify it with [DKColorTable](#dkcolortable).



A, set color picker like this with `DKColorPickerWithKey`, which generates a DKColorPicker block



```objectivec

self.view.dk_backgroundColorPicker = DKColorPickerWithKey(BG);

```



After the current theme version change to `DKThemeVersionNight`, the view background colour would switch to `#343434`.



```objectivec

[DKNightVersionManager nightFalling];

``` 



Alternatively, you could change the theme version by manager's property `themeVersion` which is a string



```objectivec

DKNightVersionManager *manager = [DKNightVersionManager sharedInstance];

manager.themeVersion = DKThemeVersionNormal;

```



## Advanced Usage



There are two approaches you can use to integrate night mode to your iOS App.



### DKNightVersionManager



The latest version for DKNightVersion add a readonly `dk_manager` property for `NSObject` returns the `DKNightVersionManager` singleton.



#### Change Theme



You can call `nightFalling` or `dawnComing` to switch the current theme version to `DKThemeVersionNight` or `DKThemeVersionNormal`.



```objectivec

[self.dk_manager dawnComing];

[self.dk_manager nightFalling];

```



Modify `themeVersion` property to switch the theme version directly.



```objectivec

self.dk_manager.themeVersion = DKThemeVersionNormal;

self.dk_manager.themeVersion = DKThemeVersionNight;

// if there is a RED column in DKColorTable.txt (default) or in 

// other `file` if you customize `file` property for `DKColorTable`

self.dk_manager.themeVersion = @"RED"; 

```



#### Post Notification



Every time the current theme version changes, `DKNightVersionManager` would post a `DKNightVersionThemeChangingNotification`. If you want to do some customisation, you can observe this notification and react with proper actions.



### DKColorPicker



`DKColorPicker` is the core of DKNightVersion. And this lib adds dk_colorPicker to every UIKit and Core Animation components. Ex:



```objectivec

@property (nonatomic, copy, setter = dk_setBackgroundColorPicker:) DKColorPicker dk_backgroundColorPicker;

@property (nonatomic, copy, setter = dk_setTintColorPicker:) DKColorPicker dk_tintColorPicker;

```



DKColorPicker is defined in `DKColor.h` file receives a `DKThemeVersion` as the parameter and returns a `UIColor`.



```objectivec

typedef UIColor *(^DKColorPicker)(DKThemeVersion *themeVersion);

```



+ Use `DKColorPickerWithKey(key)` to obtain `DKColorPicker` from `DKColorTable`



    ```objectivec

    view.dk_backgroundColorPicker = DKColorPickerWithKey(BG);

    ```



+ Use `DKColorPickerWithRGB` to generate a `DKColorPicker`



    ```objectivec

    view.dk_backgroundColorPicker =  DKColorPickerWithRGB(0xffffff, 0x343434);

    ```



### DKColorTable



`DKColorTable` is a new feature in DKNightVersion which providing us with an elegant way to manage colour setting in a project. Use as follows:



There is a file called `DKColorTable.txt`



```

NORMAL   NIGHT

#ffffff  #343434 BG

#aaaaaa  #313131 SEP

```



The first line of this file indicated different themes. **NORMAL is required column**, and others are optional. So if you don't need to integrate different themes in your app, leave the first column in this file, like this:



```

NORMAL

#ffffff BG

#aaaaaa SEP

```



`NORMAL` and `NIGHT` are two different themes, `NORMAL` is the default and for normal mode. `NIGHT` is optional and for night mode.



You can add multiple columns in this `DKColorTable.txt` file as many as you want.



```

NORMAL   NIGHT    RED

#ffffff  #343434  #ff0000 BG

#aaaaaa  #313131  #ff0000 SEP

```



The last column is the key for a colour entry, DKNightVersion uses the current `themeVersion` (ex: `NORMAL` `NIGHT` and `RED`) and key (ex: `BG`, `SEP`) to find the corresponding colour in DKColorTable.



`DKColorTable` has a property `file`, it will loads the color setting in this `file` when `+ [DKColorTable sharedColorTable` is called. Default value of `file` is `DKColorTable.txt`.



```objectivec

@property (nonatomic, strong) NSString *file;

```



You can also add another file into your project and fill your colour setting in that file.



```

// color.txt

NORMAL   NIGHT

#ffffff  #343434 BG

```



Also, do not forget to change the `file` property of the colour table.



```objectivec

[DKColorTable sharedColorTable].file = @"color.txt"

```



The code above would reload colour setting from `color.txt` file.



### Create temporary DKColorPicker



If you'd want to create some temporary DKColorPicker, you can use these methods.



```objectivec

view.dk_backgroundColorPicker =  DKColorPickerWithRGB(0xffffff, 0x343434);

```



`DKColorPickerWithRGB` will return a DKColorPicker which set background color to `#ffffff` when current theme version is `DKThemeVersionNormal` and `#343434` when it is `DKThemeVersionNight`.



There are also some similar functions like `DKColorPickerWithColors`



```objectivec

DKColorPicker DKColorPickerWithRGB(NSUInteger normal, ...);

DKColorPicker DKColorPickerWithColors(UIColor *normalColor, ...);

```



`DKColor` also provides a cluster of convenient `API` which returns `DKColorPicker` block, these blocks **return the same colour in different themes**.



```objectivec

+ (DKColorPicker)colorPickerWithUIColor:(UIColor *)color;



+ (DKColorPicker)colorPickerWithWhite:(CGFloat)white alpha:(CGFloat)alpha;

+ (DKColorPicker)colorPickerWithHue:(CGFloat)hue saturation:(CGFloat)saturation brightness:(CGFloat)brightness alpha:(CGFloat)alpha;

+ (DKColorPicker)colorPickerWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha;

+ (DKColorPicker)colorPickerWithCGColor:(CGColorRef)cgColor;

+ (DKColorPicker)colorPickerWithPatternImage:(UIImage *)image;

#if __has_include()

+ (DKColorPicker)colorPickerWithCIColor:(CIColor *)ciColor NS_AVAILABLE_IOS(5_0);

#endif



+ (DKColorPicker)blackColor;

+ (DKColorPicker)darkGrayColor;

+ (DKColorPicker)lightGrayColor;

+ (DKColorPicker)whiteColor;

+ (DKColorPicker)grayColor;

+ (DKColorPicker)redColor;

+ (DKColorPicker)greenColor;

+ (DKColorPicker)blueColor;

+ (DKColorPicker)cyanColor;

+ (DKColorPicker)yellowColor;

+ (DKColorPicker)magentaColor;

+ (DKColorPicker)orangeColor;

+ (DKColorPicker)purpleColor;

+ (DKColorPicker)brownColor;

+ (DKColorPicker)clearColor;

```



### pickerify



DKNightVersion provides a powerful feature which can generate dk_xxxColorPicker with a macro called `pickerify`.



```objectivec

@pickerify(TableViewCell, cellTintColor)

```



It automatically generates `dk_cellTintColorPicker` for you.



### DKImagePicker



Use `DKImagePicker` to change images when `manager.themeVersion` changes.



```objectivec

imageView.dk_imagePicker = DKImagePickerWithNames(@"normal", @"night");

```



The first argument passed into the function is used for `NORMAL` theme, and the second is used for `NIGHT` theme, the themes order is determined by the configuration in 

DKColorTable.txt file which is NORMAL and NIGHT.



If your file like this:



```

NORMAL   NIGHT    RED

#ffffff  #343434  #fafafa BG

#aaaaaa  #313131  #aaaaaa SEP

#0000ff  #ffffff  #fa0000 TINT

#000000  #ffffff  #000000 TEXT

#ffffff  #444444  #ffffff BAR

```



Set your image picker in this order:



```objectivec

imageView.dk_imagePicker = DKImagePickerWithNames(@"normal", @"night", @"red");

```



The order of images or names is the same in DKColorTable.txt file.



```objectivec

DKImagePicker DKImagePickerWithImages(UIImage *normalImage, ...);

DKImagePicker DKImagePickerWithNames(NSString *normalName, ...);

```
