UIAlertView not displaying complete message

问题

I have the following function to display error messages to user. But it does not seem to show the complete message. It will display upto certain characters followed by ....

How can I make it show the entire message?

(void) showAlert:(NSString*)title forMessage:(NSString*) body
{
    UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:title message:body delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];
    [alertView release];
}

There is a way.

When you present your alert, you can just implement this method:

- (void)willPresentAlertView:(UIAlertView *)alertView {
alertView.frame = CGRectMake(alertView.frame.origin.x, alertView.frame.origin.y -50
                             ,alertView.frame.size.width, 300);
}

Adjust the height to fit your need. It will look something like this:

If you need to move the button around, you can just add new lines (\n) to your message, and it will move the button down.

As mentioned by sudo rm -rf, UIAlertView has a limit.

You can try creating your own "alert" that doesn't clip by creating a view controller and showing it using presentModalViewController:animated:.
