iPhone自定义UIActionSheet
iPhone应用能不能自定义UIActionSheet的样式，默认的那个黑了吧唧太丑了
我看有些应用类似的UIActionSheet很漂亮，他们这种是完全自己实现的，还是框架有什么接口可以调用的？
类似这种：
回答：
用一个黑色的底做透明度渐变动画，同时底部放按钮的视图做位移动画就可以了。
另外我建议楼主把翻页控件的贴结了~

回答：
自己实现，自定义个view，写一个delegate，showInView，hide方法。
- (void)showInView:(UIView *)v
{
[v addsubview:self];
//通过view动画将self.center上移。
}
hide时将[self removeFromSuperView].
delegate 中定义点击了哪个按钮，在实现delegate的viewcontroller中去实现就行。
