UIAlertView - 使兩個輸入字段都安全

Question

是否可以將UIAlertView這兩種輸入類型作爲密碼類型？
我正在實施更改密碼功能，並想知道這是否可能。

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

你去那裏：

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