objective-c - Objective-C : Can the Countdown timer Picker be used as a hour/min picker?

Question

我想知道我是否可以直接使用标准倒计时选择器作为小时/分钟选择器，例如用户可以选择小时数和分钟数作为 parking 时间等...

基本上，我希望在没有倒计时功能的情况下使用倒计时选择器界面。

Answer 1

是的，它非常适合这个。

参见 here :

The UIDatePicker class implements an object that uses multiple rotating wheels to allow users to select dates and times. iPhone examples of a date picker are the Timer and Alarm (Set Alarm) panes of the Clock application. You may also use a date picker as a countdown timer.

你也可以用它来发挥创意。
