UIAlertView - 使两个输入字段安全

Question

是否可以将UIAlertView的两种输入类型都作为密码类型？
我正在实施 更改密码 功能，想知道这是否可行。

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Change password" message:nil delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Change password", nil];
alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
[alert textFieldAtIndex:0].placeholder = @"New password";
[alert textFieldAtIndex:1].placeholder = @"Confirm password";
[alert show];

Answer 1

好了：

[alert textFieldAtIndex:0].secureTextEntry = YES;
[alert textFieldAtIndex:1].secureTextEntry = YES;
