In Demo

1. create TestTableViewCell class, also create xib.
2. dray label and button, layout like TableViewCell, set the text color (Red or else) using xib
3. don't set textColor for TestTableViewCell, only set nightTextColor, like this

- (void)awakeFromNib {
    [DKNightVersionManager addClassToSet:self.class];

    self.label.numberOfLines = 0;
    self.label.text = @"DKNightVersion is a light wei-ght framework adding night   version to your iOS app.";
//    self.label.textColor = [UIColor darkGrayColor];
    self.label.lineBreakMode = NSLineBreakByCharWrapping;
    self.nightBackgroundColor = UIColorFromRGB(0x343434);
}

1. register this nib, and use it replace TableViewCell
2. run
3. switch night and day theme, then you will see label color can't change back to Red color.

I think this code cause the problem:

- (void)hook_setTextColor:(UIColor*)textColor {
    if ([DKNightVersionManager currentThemeVersion] == DKThemeVersionNormal) [self setNormalTextColor:textColor];
    [self hook_setTextColor:textColor];
}

May be UILabel don't call setTextColor: method, instead directyly using _textColor = [UIColor xxxColor]

Hi,Draveness Your work great, like the sunshine. hah

At iPhone 6Plus, click cell and go into the detail view, then come back and change the neight mode, it will crash.

Wating for your message.

I want to customize my own theme for night mode. However, when I finish editing the property.json and run rake, it raise an error.

The error log goes like this:

......

I'm not in good command of ruby, sorry.

为什么我pod 下来之后，项目中有DKColorTable.txt这个文件，但是代码执行完成之后为 nil,提示这个这个文件名无效，如下 ：

2017-03-10 16:54:49.586110 ******[19741:7217448] Error reading file: The file name is invalid. 2017-03-10 16:54:51.134092 ******[19741:7217448] DKColorTable: (null)

本想 pull requests的，但是发现UIKit部分都是模板生成的，所以就尴尬了。夜间模式时，希望给UIImageView的alpha值改小一点，不然有点刺眼。 所以加了一个这个：

@property (nonatomic, copy, setter = dk_setAlphaPicker:) DKAlphaPicker dk_alphaPicker;

然后有个

typedef CGFloat (^DKAlphaPicker)(DKThemeVersion *themeVersion);

DKAlphaPicker DKAlphaPickerWithAlphas(CGFloat normal, ...);

@interface DKAlpha : NSObject
+ (DKAlphaPicker)alphaPickerWithAlpha:(CGFloat)alpha;
@end

在tableViewCell点击的时候设置了，[self.tableView deselectRowAtIndexPath:indexPath animated:YES]; // 取消选中状态，在日间模式下选中到取消选中过度很流畅，但是夜间模式会有跳跃，在突然冲选中到取消；对于键盘的夜间模式：发现在夜间模式下也对textFile做了处理，感觉很不错，但是textView和searchBar没有做出相应的处理希望能够完善。还有在已经完成的项目中添加这个库，我使用的办法是在每一个控件都添加一句代码实现夜间模式，你有什么好的建议来更好的使用这个库吗？

Hi, @Draveness , as title said, it's a bit difficult to increase theme dynamically in one file (ColorTable.txt), so I think it's better to refactor and abstract picker getter layer and storage layer.

Limit:

• all themes in one files.
• picker getter layer strongly couple with storage layer.

Enhancement:

• abstract picker getter layer and storage layer.

As A Result:

After refactor and abstract, we can save themes into respective file. and have custom picker getter from storage layer, which has been abstracted. if user can download theme, they only have to download one theme file, into sandbox, the directory structure maybe:

Documents
└── Themes
    ├── Night.theme
    ├── Normal.theme
    └── Summer.theme

if you think it right, and no time to refactor, I'm glad to send PR :) .

The only way to set self.navgitaionItem.title's color is to set TitleTextAttributes instead of the color. for example. NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys: [UIColor blackColor],NSForegroundColorAttributeName, nil]; [self.navigationController.navigationBar setTitleTextAttributes:dic]; self.navigationItem.title = @"theTitleIWantToChangeColor";

but the way you offer can;t solve this.

So, I overwrite the method - (void)night_updateColor in UINavigationBar+Night.m and add a property to support that, but this is just a temp way to solve this. Hope you offer a better way to solve this.

• (DKColorPicker)dk_titleTintColorPicker { return objc_getAssociatedObject(self, @selector(dk_barTintColorPicker)); }

• (void)dk_setTitleTintColorPicker:(DKColorPicker)picker{ objc_setAssociatedObject(self, @selector(dk_titleTintColorPicker), picker, OBJC_ASSOCIATION_COPY_NONATOMIC); UIColor *color = picker(self.dk_manager.themeVersion); NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys: [color copy],NSForegroundColorAttributeName, nil]; [self setTitleTextAttributes:navbarTitleTextAttributes]; [self.pickers setValue:[picker copy] forKey:@"setTitleTextAttributes:"]; }

• (void)night_updateColor { [self.pickers enumerateKeysAndObjectsUsingBlock:^(NSString * _Nonnull selector, DKColorPicker _Nonnull picker, BOOL * _Nonnull stop) { SEL sel = NSSelectorFromString(selector); id result = ((DKColorPicker)picker)(self.dk_manager.themeVersion); if([selector isEqualToString:@"setTitleTextAttributes:"]) { result = [NSDictionary dictionaryWithObjectsAndKeys: [result copy],NSForegroundColorAttributeName, nil]; } [UIView animateWithDuration:DKNightVersionAnimationDuration animations:^{ #pragma clang diagnostic push #pragma clang diagnostic ignored "-Warc-performSelector-leaks" [self performSelector:sel withObject:result]; #pragma clang diagnostic pop }]; }]; }

之前可以正常编译运行，重新pod install后报错。 是版本更新的问题吗？按照readme的文档改了之后还是报错。

_backView.dk_backgroundColorPicker = DKColorWithColors(KCOLOR_YELLOW_FDF5D8, [UIColor colorWithRGBHex:0x343434]);

We are using 0.9.3. If you fix this bug in the latest release, feel free to close it.

if in two class use @pickerify(TableViewCell, cellTintColor),a warning to me, it said "same method from another category",how to fix it? Thanks

instance.themeVersion = themeVersion;这句代码使用了setter方法，在setter方法中发送通知修改主题，而如果某控制器中在自定义方式获取单例self.dk_manage就与该方法冲突造成了循环锁错误。本人认为解决办法应该是改成instance->_themeVersion = themeVersion.

I've been using this library since a long time and I love it. I am able to change from dark to light mode before iOS13.

How can I use this library in multiwindow? When a scene goes away the system calls dark/light mode methods repeatedly... I think this should not be a singleton anymore to be able to alloc and pass an instance to each scene.

What do you think?
