修改UIDatePicker选择指示器的颜色 [英] Modify UIDatePicker selection indicator tint color

问题描述

是否可以修改 UIDatePicker 的选择指示器的颜色？还是可以删除它，以便我可以添加自己的选择指示符图像？

Is it possible to modify the tint color of a UIDatePicker's selection indicator? Or can it be removed so I can add my own selection indicator image?

在 UIPickerView 的情况下我知道您可以禁用选择指示器，以便提供自己的选择指示器图像。

I know in the case of UIPickerView´s you can disable the selection indicator so that you can provide your own selection indicator image.

推荐答案

没有可供更改的选项默认情况下，选择指示器的颜色。
不过，您可以采取解决方法。我将添加一个简单的 UIView ，该颜色具有您选择的颜色和透明度的alpha值。 Se的大小和坐标相应于原始选择指示器以覆盖它（大小为280x44，标准选择器的坐标为20/130-不确定，因此请找出正确的值，以防它们不匹配）。

There is no option to change the color of selection indicator by default. You can make a workaround though. I would add a simple UIView with a color of your choice and alpha value for transparency. Se the size and coordinates accordingly to the original selection indicator to overlay it (size 280x44, coordinates 20/130 for standard picker - not sure about that so find out the right values in case these don't match).

UIView *overlayIndicator = [[UIView alloc] initWithFrame:CGRectMake(20, 130, 280, 44)];
overlayIndicator.backgroundColor = [UIColor redColor];
overlayIndicator.alpha = 0.5f;
[yourDatePicker addSubview:overlayIndicator];

希望您可以从这里开始。

Hope it's something you can start with.
