如何在Ipod中创建可编辑列表，例如播放列表？

Question

In my Iphone App,which is a multiple view application using arc and storyboard, i want to create a editable list, like the playlist in the iphone's integrated ipod. when i click on the edit button there should be little red '-' images left of the items texts and there also should appear a '+' button on the navigation bar where i can add new items to the list.

You see it should be similar to the playlists in the ipod. Does anybody knows any tutorial about that or something else? I googled for 2 hours but found nothing -.-

I would be very happy if you can help me with this

Thanks

Answer 1

If you are using the lastest Xcode, try making a 'Master Detail' application.

That should provide with you with basic editing functionality in a UITableView .

Answer 2

Use a UITableView , for the small '-' and the '+' you can create buttons with the intended task as actions. If you want the specific red '-' buttons then I think they are available in the ios sdk.

Answer 3

The '+' and '-' signs are accessories for the tableViewCell . So to set them, you need to set the accessoryType property of the UITablewViewCell . If you look at the class reference, there's a list of them, including the buttons. What I would also do is have a bool value for each cell, and have the accessoryType be '+' or '-' depending on the value of the bool, and have the value itself change every time the user touches the cell. That way the sign will switch every time a cell is touched, and at the end you can go through and save or discard the things in each cell based on it's bool value.
