如何在popover中呈现键盘？，ipad密码锁定风格 [英] How to present keyboard inside popover?, ipad passcode lock style

问题描述

当您为ipad设置密码时，是否可以显示键盘的方式？

Is it posible to present a keyboard the way is shown when you set a passcode for your ipad?

推荐答案

不幸的是没有，但我复制的是，使用界面构建器在我的密码视图中构建了一堆键盘，如键盘。然后将每个按钮链接到将更改文本字段的命令。

Unfortunately no, But what i did to replicate this was, built a bunch of buttons like a keyboard inside my passcode view using interface builder. Then linked each button to a command that would change the text field.

- (IBAction) button9_clicked:(id) sender{

    if ([self textField:theTextField shouldChangeCharactersInRange:range replacementString:@"9"]){
        self.theTextField.text=[self.theTextField.text stringByAppendingString:@"9"];
        range.location = self.theTextField.text.length;
    }
    else 
        range.location = self.theTextField.text.length;
}
