您现在可以创建带有样式的 UIAlertView。

UIAlertView 现在有一个属性 - alertViewStyle，您可以将其设置为枚举值之一

1. UIAlertViewStyleDefault

2. UIAlertViewStyleSecureTextInput

3. UIAlertViewStylePlainTextInput

4. UIAlertViewStyleLoginAndPasswordInput

创建警报视图后，您可以设置它的样式并显示它。解除警报后，您可以使用警报视图的 textFieldAtIndex 属性访问字段的内容。

否则你也可以使用这个。,

IAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter Name"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];

UITextField *nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[nameField setBackgroundColor:[UIColor whiteColor]];
[dialog addSubview:nameField];
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 70.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];
[nameField release];

希望这些信息有所帮助。谢谢你。
