Is it possible to put UIPickerView into UIAlertView?If yes, 开发者_StackOverflow社区can you give an example?

There's an example here of adding a UITableView, you should be able to adapt it to suit your purposes.

but in UIActionSheet

[actionSheet addSubview:pickerMoney];

Heading

Nope. But you can embed a picker in a UIActionSheet, which lets you give the user a nice slide up and slide down animation when showing or dismissing the picker.

There are a couple of good examples of the technique here and here.

No, UIAlertView only has buttons and you can only set their titles.
