我有一个存储缓存颜色的 plist 文件，它看起来像这样

<key>CachedColors</key>
<dict>
    <key>com.Halfbrick.Fruit</key>
    <string>0.00000,0.00000,0.00000</string>
    <key>com.apple.Preferences</key>
    <string>0.28824,0.37059,0.48235</string>
</dict>

我想要做的是使用 3 个值来创建 UIColor，UIColor 将根据捆绑 id 改变，值是红色、绿色和蓝色

但我希望 UIColor 在捆绑 ID 更改时自动更改，我将其用作横幅的背景颜色，并说如果我在主屏幕上并收到通知，则背景为白色，但是如果我打开“设置”应用程序，我希望它从 plist 中更改为 com.apple.Preferences 的 RGB 值，类似于在 iOS 6 中打开应用程序以匹配 UINavigationBar 时状态栏背景如何自动更改

我用了：

SBApplication *frontApp = [(SpringBoard*)[UIApplication sharedApplication] _accessibilityFrontMostApplication];
NSDictionary *statusBarCachedColors = [NSDictionary dictionaryWithContentsOfFile:@"/var/mobile/Library/Preferences/cc.tweak.statuscolor.plist"];
NSString *colorString = [statusBarCachedColors objectForKey:frontApp];
NSArray *components = [colorString componentsSeparatedByString:@","];
UIColor *tintColor = [UIColor colorWithRed:[components[0] floatValue] green:[components[1] floatValue] blue:[components[2] floatValue] alpha:1.0];

从 plist 中获取该字符串后：

NSArray *components = [string componentsSeparatedByString:@","];
UIColor *color = [UIColor colorWithRed:[components[0] floatValue] green:[components[1] floatValue] blue:[components[2] floatValue] alpha:1];

...或者在旧的编译器上

UIColor *color = [UIColor colorWithRed:[[components objectAtIndex:0] floatValue]
                                 green:[[components objectAtIndex:1] floatValue]
                                  blue:[[components objectAtIndex:2] floatValue] alpha:1];

如果问题包含其他内容，则很难遵循标点符号
