ios - 使用 secureTextEntry 为 UITextField 选择键盘语言

Question

我遇到了更改密码字段语言的问题。在我的应用程序中，我需要在不关心当前语言环境的情况下以希伯来语输入登录名/密码。当我尝试输入登录名时，一切正常，我可以将键盘更改为希伯来语并输入登录名。但是当我尝试在安全文本字段中输入密码时，键盘出现时没有选择语言按钮，所以我只能输入英文字母。

问题是登录名/密码可以是英语或希伯来语。

如何将选择语言按钮放到 protected 文本字段中？

没有找到解决方案。不得不制作这个片段:

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
textField.text = [textField.text stringByReplacingCharactersInRange:range withString:string];

NSString *pass = password;
pass = [pass stringByReplacingCharactersInRange:range withString:string];

[password release];
password = nil;

password = [[NSString stringWithString:pass] retain];

[self hideTextInTextFieldExceptOne:string];

[self performSelector:@selector(hideTextInTextField) withObject:self afterDelay:1.0];

return NO;
}

- (void)hideTextInTextFieldExceptOne:(NSString *)string
{    
int lenght = [passwordTextField.text length];

for (int i = 0; i < lenght-1; i++)
{
    NSRange range = NSMakeRange(i, 1);
    passwordTextField.text = [passwordTextField.text stringByReplacingCharactersInRange:range withString:@"*"];
}
}

- (void)hideTextInTextField
{
NSUInteger lenght = [passwordTextField.text length];
passwordTextField.text = @"";

for (int i = 0; i < lenght; i++)
{
    passwordTextField.text = [passwordTextField.text stringByAppendingString:@"*"];
}
}
