iOS会像锁定屏幕一样显示锁定/解锁滑块吗？

Question

I'm trying to let the users of my app cancel an active alarm using a slider, like the timer app or the iPhone lock screen.

Is this control available to us as developers? If so, what's the name of it, and do I need to add it programmatically? I do not see it in the interface builder.

Thank you!

It's not a standard control - you'll need to create it yourself.

However, I think you should be able to customize the slider control. You can change the look and feel of that by supplying your own graphics, and it should be easy to simulate the behavior of the lock slider (such as making it slide back to 0 if it doesn't get all the way across).
