[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardWillShowNotification object:nil];//键盘的弹出
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillBeHidden:) name:UIKeyboardWillHideNotification object:nil];//键盘的消失
#pragma mark ----- 键盘显示的时候的处理
- (void)keyboardWasShown:(NSNotification*)aNotification
