添加监听

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(changeContentViewPosition:)
                                             name:UIKeyboardWillShowNotification
                                           object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(changeContentViewPosition:)
                                             name:UIKeyboardWillHideNotification
                                           object:nil];

移除监听

[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];

事件处理函数

- (void) changeContentViewPosition:(NSNotification *)notification{

    NSDictionary *userInfo = [notification userInfo];
    NSValue *value = http://www.mamicode.com/[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey];>
