ColorPickerView

##学习Keynote，写了个属于自己的颜色选择器，用CALayer和其子类显示颜色条，用UIWindow自己封装成MenuController等等，代码高度内聚（一个类搞定），且简单实用。

CocoaPods集成

 pod 'LSLColorPickerView'

一、实用说明：

1.实例化

/// color picker view (size must be given)
_colorPickerView = [[LSLHSBColorPickerView alloc] initWithFrame:_contentView.bounds]; [_contentView addSubview:_colorPickerView]; /// selected color preview	
_currentSelectedColorPreview.backgroundColor = _colorPickerView.preColor;
/// selected color block	
__weak typeof(self) weakSelf = self; [_colorPickerView colorSelectedBlock:^(UIColor *color, BOOL isConfirm) { /// do something...	///	
weakSelf.currentSelectedColorPreview.backgroundColor = color; weakSelf.currentSelectedColor = color; }];	

2.保存（或清空）本地文档（归档）中的数据

#pragma mark - save or clean colors in archiver
- (IBAction)saveSelectedColorToArchiver {
if (self.currentSelectedColor) {
[self.colorPickerView saveSelectedColorToArchiver];
self.currentSelectedColor = nil;
}
}
- (IBAction)cleanCache:(id)sender {
[LSLHSBColorPickerView cleanSelectedColorInArchiver];
}
