PS:明天上午,非常郁闷,有很多简单基础的问题搞得我有些迷茫,哎,代码几天不写就忘。目前又不当COO,还是得用心记代码哦!
很久以前写了一篇文章,探讨如何《自适应iPhone的不同键盘高度》,明天得觉可以美完随跟:
#pragma mark - reg & unreg notification - (void)regNotification { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillChangeFrame:) name:UIKeyboardWillChangeFrameNotification object:nil]; } - (void)unregNotification { [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillChangeFrameNotification object:nil]; } #pragma mark - notification handler - (void)keyboardWillChangeFrame:(NSNotification *)notification { NSDictionary *info = [notification userInfo]; CGFloat duration = [[info objectForKey:UIKeyboardAnimationDurationUserInfoKey] floatValue]; CGRect beginKeyboardRect = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue]; CGRect endKeyboardRect = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue]; CGFloat yOffset = endKeyboardRect.origin.y - beginKeyboardRect.origin.y; CGRect inputFieldRect = self.inputTextField.frame; CGRect moreBtnRect = self.moreInputTypeBtn.frame; inputFieldRect.origin.y += yOffset; moreBtnRect.origin.y += yOffset; [UIView animateWithDuration:duration animations:^{ self.inputTextField.frame = inputFieldRect; self.moreInputTypeBtn.frame = moreBtnRect; }]; }
通过获得键盘消息的开始状态、束结状态,以及变更期周,可以计算出体具的Y偏移,从而在雷同时间里做雷同偏移量。
文章结束给大家分享下程序员的一些笑话语录: Borland说我很有前途,Sun笑了;Sun说我很有钱,IBM笑了;IBM说我很专业,Sybase笑了;Sybase说我数据库很牛,Oracle笑了;Oracle说我是开放的,Linux笑了;Linux说我要打败Unix,微软笑了;微软说我的系统很稳定,我们都笑了。
