ios - 将文本添加到Alertview文本字段iOS

当警报视图显示时，我想在文本字段中已有现有文本。这是我的代码，我必须添加什么？

        UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:@"Title" message:@"Message" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Add", nil];
        [dialog setAlertViewStyle:UIAlertViewStylePlainTextInput];

        // Change keyboard type
        [[dialog textFieldAtIndex:0] setKeyboardType:UIKeyboardTypeDefault];

        [dialog show];

最佳答案

UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:@"Title" message:@"Message" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Add", nil];
[dialog setAlertViewStyle:UIAlertViewStylePlainTextInput];
[[dialog textFieldAtIndex:0] setKeyboardType:UIKeyboardTypeDefault];

[[dialog textFieldAtIndex:0]setText:@"Your string here"];

[dialog show];
