推荐答案
这可能违反 HIG 指南，即不关闭 UIAlertView.
That might be against HIG Guidelines to NOT to dismiss an UIAlertView.
解决方法:我不知道您的应用程序中发生了什么，但要实现此目的，您可以做的是关闭 AlertView，然后检查是否设置了 textView 的文本.如果设置为nil，则再次调出alertview！
WORKAROUND : I don't know what goes on in your app, but to acheive this thing, what you could do is dismiss the AlertView and then check if textView's text is set or not. If it is set to nil, then bring up the alertview again!
