Question

如何在uipickerview的选择指示器上写文本

Answer 1

The simplest approach will be just to add UILabel with your text over the UIPickerView . You only need to find the right coordinates so text will be placed well.

Answer 2

If you want to display text on it try adding a UILabel as a subview to the view containing the picker. You just need to get the frame in the right spot - easy with IB, more trial and error through code. The set label to have a clear background. Just update the label value as needed.
