Question

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将根据包ID更改，值为红色，绿色和蓝色

但我希望UIColor在包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获得通知，背景是白色，但如果我打开设置应用程序，我希望它从plist排序改为com.apple.Preferences的RGB值，在iOS 6中，状态栏背景在打开应用程序以匹配UINavigationBar时自动更改< / p>

我用过：

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中拿起那个字符串后：

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

...或者在较旧的编译器上

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
