有没有一种简单的方法在iPhone上创建模态按钮菜单？

Question

Plenty of applications seem to do this. For example, go to Apple's mail application and press the "reply" button on the toolbar. You'll get a menu with buttons that say "Reply", "Reply All", "Forward" and "Cancel" that will scroll up from the bottom.

The way I figure I could do this is to create a short view in IB with the buttons I want, present it modally, and right a view controller to handle the buttons.

It seems like this is so common that there must be an easier way to do it (like how easy it is to add to the toolbar and navigation bar).

Is there some widget or shortcut that I am missing?

Answer 1

This is actually just a UIActionSheet. You can create one pretty easily.

只需在IB中创建一个具有所需控件的视图控制器，然后在当前视图控制器上调用[self presentModalViewController:[[[MyModalViewController alloc] init] autorelease] animated:YES] 。
