问题 I'm using UIPickerView with (for example) 4 rows. The first value is "Pick a value" with gray text. The others are values the user should pick with black text. The picking is optional, so users could just skip it. But if they don't, how to make first value unselectable back after user will start picking? Thanks. Regards. 回答1: Use the UIPickerView delegate method - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component to change the selected

问题 I have a UIActionSheet containing a picker and a UIToolbar. On the UIToolBar there is a save button. However, some of my users reported pressing the save button before the UIPickerView stops spinning thus only retrieving the initial value (before spinning).

Thanks 回答1: Even if they dismiss the picker while it's still spinning, the

问题 I've got a Picker that comes up as the inputView for UITextField instead of a keyboard. The user dials in their choice, saves and then dismisses the view. When you come back to that view and go to dial in a new choice the picker is out of sync with the data that was saved. The picker is using an array of strings for a datasource. So for example looking at the picture below you can see that the picker is in it's first position which is empty. But what I want is for the picker to dial in to RE2
