ios - ios8 键盘高度有所不同

Question

我使用下面的代码来获取键盘高度，与使用ios8的iPhone 5s设备相比，使用ios7的iPhone4s设备，键盘高度有所不同。因此，当我在使用ios8的iPhone5s中点击它时，我的文本字段移动得非常高，而相同的代码有效在 iPhone 4s 和 ios7 上都可以。有人可以指导如何在两个版本中解决该问题吗？

- (void)keyboardWasShown:(NSNotification*)notification
{
    NSDictionary* info = [notification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    float kbHeight;
    if (([UIApplication sharedApplication].statusBarOrientation== UIDeviceOrientationPortraitUpsideDown)||([UIApplication sharedApplication].statusBarOrientation== UIDeviceOrientationPortrait))
    {
        kbHeight=kbSize.height;
    }
    else
    {
        kbHeight=kbSize.width;
    }



    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbHeight, 0.0);

    self.scroll.contentInset = contentInsets;
    self.scroll.scrollIndicatorInsets = contentInsets;

    CGRect rect = self.view.frame;
    rect.size.height -= (kbHeight);


    if (!CGRectContainsPoint(rect, self.activeField.frame.origin))
    {
        CGPoint scrollPoint = CGPointMake(0.0, self.activeField.frame.origin.y - ((kbHeight) - self.activeField.frame.size.height));
        [self.scroll setContentOffset:scrollPoint animated:NO];
    }
}

Answer 1

只需替换代码中的行

CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

与

CGSize kbSize = [[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;

让我知道它是否有效
