iPhone常用控件、UIActionSheet、UIAlertView

核心提示：actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{ if (buttonIndex != [actionSheet cancelButtonIndex]) { NSString *text

actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{ if (buttonIndex != [actionSheet cancelButtonIndex]) { NSString *text = [[NSString alloc] initWithFormat:@"test alert"]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Something was done." message:text delegate:self cancelButtonTitle:@"OK!" otherButtonTitles:nil]; [alert show]; [alert release]; [text release]; }}//- (void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex//{// NSLog(@"%d",buttonIndex);//}

示例：

视图有一个UISegmentedControl,"Switches"下有两个UISwitch

"Button"下有一个“Do Something"的UIButton

触摸"Do Something"Button时弹出UIActionSheet

触摸选择"Yes,I'm sure."时弹出 UIAlertView
