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 ....

如何让它显示整个消息？

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];
}

推荐答案

有一种方法。

当您出示提醒时，您可以实施此方法：

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);
}

调整高度以满足您的需要。它看起来像这样：

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

如果你需要移动按钮，你可以添加新行（ \ n ）到你的消息，它将按下按钮。

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.
