【问题描述】：

我想快速使用这个库。它是用 Obj-C 编写的。

我已经添加了标题和桥接等，现在我不知道这个语句的等价物是什么：

        //Color did change block declaration
    NKOColorPickerDidChangeColorBlock colorDidChangeBlock = ^(UIColor *color){
        //Your code handling a color change in the picker view.
    };

    NKOColorPickerView *colorPickerView = [[NKOColorPickerView alloc] initWithFrame:CGRectMake(0, 0, 300, 340) color:[UIColor blueColor] andDidChangeColorBlock:colorDidChangeBlock];

    //Add color picker to your view
    [self.view addSubview:colorPickerView];

【解决方案1】：

let colorPickerView = NKOColorPickerView(frame: CGRect(x: 0, y: 0, width: 300, height: 340), color: UIColor.blueColor()) { (color) -> Void in
    // Your code handling a color change in the picker view.
}

view.addSubview(colorPickerView)

或

var colorDidChangeBlock: NKOColorPickerDidChangeColorBlock = { (color) in
    // Your code handling a color change in the picker view.
}

let colorPickerView = NKOColorPickerView(frame: CGRect(x: 0, y: 0, width: 300, height: 340), color: UIColor.blueColor(), andDidChangeColorBlock: colorDidChangeBlock)
view.addSubview(colorPickerView)

我更喜欢第一种方式。它更清晰，更易于阅读。
