UIAlertView - 使两个输入字段都安全

Question

是否可以将UIAlertView这两种输入类型作为密码类型？
我正在实施更改密码功能，并想知道这是否可能。

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

你去那里：

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