UIDatePicker：获取出现在两个文本字段中的日期

Question

I have searched the internet and this site for many hours - I have found a number of similar questions, and have tried the suggestions people made, but I can't seem to get anything to work with the code I am using.

Here is what is going on:

I have two text fields (dateOpened and dateClosed) that I would like the date to appear in. When you click on each textfield the datepicker appears (I was able to get that part to work). However, I am having an issue getting the date to appear in the dateClosed textfield.

For dateOpened - when I click on the textfield, the datepicker comes up, I select a date, and it appears in that textfield. It works great!

The Problem:

For dateClosed - when I click on the textfield, the datepicker comes up (works great), I select a date, but it appears in the dateOpened textfield, not dateClosed like it is supposed to.

I would really appreciate any suggestions on how to get the date to appear in the dateClosed textfield. Thank you!!! :)

3 steps

• Identify which text field to be filled [start date or end date],use a flag[using delegates ]
• Show date picker and get date collected by user
• according to the first methods identified result[flag] save the date value for further use accordingly as start date and end date[if loop]

here your method didn't implement getting value to self.closedDate
