Hi all,
I have a couple of problems with the Xcode programming for IOS. I'm a newbie in Xcode programming, and english is not my first language. So please bear with me.
Basically, I have a tableview with 2 custom tableviewcells. I have tap gesture recognition in tableview. In one of the custom tableviewcells I have a uitextfield for selecting the date. I used to be using action sheet, but since I use the newest Xcode, it generate warning. So I switch to using uiview show the date picker with one toolbar button, done button.
The first problem that I encountered was the button click was not registered to target selector of the button. I searched the google, and found out that the tap gesture in tableview was the problem. So I create another tap gesture to point to the view. It works.
When I click the uitextfield in tableview, it shows the uiview (half screen) with date picker and done button. It works as expected, even the date picker delegate works correctly.
The problem was, in the selector target of the gesture recognition, I can't refer to uiview that I created before. So I'm at lost how to dismiss the uiview after the button was click.
Thanks all for your help
