禁用UIPickerView中的特定行值 [英] Disable particular row value in UIPickerView
问题描述
我正在尝试禁用pickerView中的特定行。
I am trying to disable particular row in pickerView.
我有一个pickerView的字符串数组。当用户选择特定行时,我在array1中追加值。
I have an array of strings for pickerView. I am appending values in array1 when user selects particular row.
之后我想在用户再次打开pickerView时执行此操作,如果array1具有数组值,则应禁用pickerView的值。
After that I want to do that when user again opens pickerView if array1 has values of array, pickerView's that value should be disabled.
我该怎么做?
