在UIAlertView中关闭UITextField的键盘

Question

我有一个自定义的UIAlertView.我在该AlertView中有一个UITextField,它一出现就成为firstResponder.现在,当用户触摸AlertView中的其他位置时,我需要关闭该UITextField的键盘.我已经接触过此次活动.

一切都到位并且工作正常,除非我在UITextField上调用resignFirstResponder,它从第一个响应者辞职但键盘没有被解雇.有没有办法解雇那个键盘.

我一直在寻找解决方案,并在这里发现了类似的帖子,没有答案

如果有人能找到出路请告诉我.我甚至尝试了以下方式,但它不起作用

UIWindow* tempWindow;

    // Because we cant get access to the UIKeyboard throught the SDK we will just use UIView. 
    // UIKeyboard is a subclass of UIView anyways
    UIView* keyboard;

    // Check each window in our application
    for(int c = 0; c < [[[UIApplication sharedApplication] windows] count]; c ++)
    {
        // Get a reference of the current window
        tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:c];
        for(int i = 0; i < [tempWindow.subviews count]; i++)
        {
            // Get a reference to the current view
            keyboard = [tempWindow.subviews objectAtIndex:i];

            // Loop through all views in the current window

            if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES){
                [keyboard removeFromSuperview];
            }

        }
    }

你必须在UIAlertField上调用resignFirstResponder,

例如:

[textField resignFirstResponder];[alertView resignFirstResponder];
