为什么UIPickerView是半透明的 [英] Why UIPickerView is semi transparent

问题描述

为什么UIPickerView不是％100不透明的? 当我将文本颜色设置为白色并将UIPickerView放在红色背景上时，UIPickerView项的文本颜色为红白色.

Why UIPickerView is not %100 opaque? When I set text color to white and put UIPickerView on a red background, the UIPickerView items have a reddish white text color.

我尝试使用viewForRow进行自定义视图，但是仍然没有效果.

I tried custom views using viewForRow, but still no effect.

如何将UIPickerView的不透明度设置为％100? 在IB中，alpha为1，但实际上在运行时并非如此

How can I set opacity of UIPickerView to %100? In IB it's alpha is 1 but actually in runtime it isn't

推荐答案

请尝试使用此委托并创建自己的自定义视图并返回.

Please try this delegate and make your own customize view and return it.

-(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:
