Question

这是我在使用此代码时得到的结果：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"Rank on ScoreBoard: %d",positionOnBoard] message:@"" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"Submit", nil];
nameField = [[UITextField alloc] initWithFrame:CGRectMake(12, 25, 260, 21)];

[nameField setBackgroundColor:[UIColor whiteColor]];
[nameField setPlaceholder:@"Your Name Here!"];

[alert addSubview:nameField];

[alert show];

[nameField becomeFirstResponder];

[alert release];

如你所见，它搞砸了。 它只发生在将我的项目升级到iOS 4.0时。

最终我通过在InitWIthTitle参数中添加“\ n”（YES，它是\ n后面的空格）来增加UIAlertView的高度来解决它，然后我有足够的空间来正确放置UITextField。
