Use of iOS UIAlertView and UIActionSheet

UIAlertView is similar to MessageBox on Windows. A small record, ah! I want to write down everything that I want to write down, even though it is simple and the related technical documents of Apple are also described. The initial stages of obsessive-compulsive disorder show up ....

Code:

General Usage

UIAlertView *alert =[[UIAlertView alloc] initWithTitle:@"hello"                      message:@"I'm Apple"                              delegate:self                              cancelButtonTitle:@"ok"                         otherButtonTitles:nil];[alert show];[alert release];

When there are multiple buttons

UIAlertView * alert = [[UIAlertView alloc] initWithTitle: @ "hello" message: @ "O ha" delegate: self cancelButtonTitle: @ "OK" otherButtonTitles: @ "cancel ", @ "Ignore", nil];

In UIAlertViewDelegate

-(Void) alertView :( UIAlertView *) alertview

ClickedButtonAtIndex :( NSInteger) buttonIndex

You can see the button you clicked.

 

UIActionSheet is a modal dialog box popped up from the bottom of the screen. Its usage is also very simple.

UIActionSheet *actionSheet = [[UIActionSheet alloc]        initWithTitle:@"Are you sure?"        delegate:self        cancelButtonTitle:@"No Way!"        destructiveButtonTitle:@"Yes, I'm sure!"        otherButtonTitles:nil];    [actionSheet showInView:self.view];
