Question

使用xcode 4.3.2

我是新手，所以请保持简单的答案。我试图按照例子但没有任何作用。我有一个包含文本字段的页面。底部被键盘隐藏。我想要的是能够向上滚动以便我可以填写那些隐藏的字段。我附上了我的.m文件。

您可以注册UIKeyboardDidShowNotification并设置滚动视图的contentInset，使底部插图等于键盘框架的高度（请参阅通知的UIKeyboardFrameEndUserInfoKey键{{1} }}）。同样，当您收到userInfo时，只需将UIKeyboardWillHideNotification重置为contentInset。

无法滚动ScrollView
