問題描述

我想要一個帶有非透明鍵盤的鍵盤 - 我無法使用任何受支持的 UIKeyboardTypes 來實現.有沒有其他辦法解決這個問題?

I would like to have a keyboard with a non-transparent keyboard - I couldn't get this with any of the supported UIKeyboardTypes. Is there another way around this?

我想我可以用我想要的顏色覆蓋鍵盤下方的背景視圖 - 是否有一種好方法可以使背景視圖與鍵盤顯示動畫同步?

I suppose I could just overlay a background view under the keyboard with the color I want - would there be a good way to animate that background view in sync with the keyboard show animation?

推薦答案

在 Xcode 5 中使用 iOS 7 的 Base SDK 編譯應用時，iOS7 中的鍵盤是半透明的.
如果您在 Xcode 4.6.x 上構建應用程序，您將像以前一樣擁有非半透明鍵盤.
(我知道這是一個糟糕的修復，但我想我會建議它)

The keyboard in iOS7 is translucent when app is compiled in Xcode 5 with a Base SDK of iOS 7.
If you build the app on Xcode 4.6.x instead, you'll have the non-translucent keyboard as before.
(i know this is a shitty fix but nonetheless, i thought i'd suggest it)

無論如何，您也可以嘗試使用默認鍵盤通知:

anyways, you could alternatively try making use of the default keyboard notifications:

1. UIKeyboardWillShowNotification
2. UIKeyboardWillHideNotification

應該是這樣的:

-(void)viewWillAppear:(BOOL)animated
{
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillShow:)
                                                 name:UIKeyboardWillShowNotification
                                               object:nil];

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

-(void)viewWillDisappear:(BOOL)animated
{
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:UIKeyboardWillShowNotification
                                                  object:nil];

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

-(void)keyboardWillShow:(NSNotification *)note
{
    /*
     Would have used:
     CGRect rectStart = [note.userInfo[UIKeyboardFrameBeginUserInfoKey] CGRectValue];
     CGRect rectEnd = [note.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];

     Reason for not using:
     The above two keys are not being used although, ideally, they should have been
     since they seem to be buggy when app is in landscape mode

     Resolution:
     Using the deprecated UIKeyboardBoundsUserInfoKey since it works more efficiently
     */

    CGRect rectStart_PROPER = [note.userInfo[UIKeyboardBoundsUserInfoKey] CGRectValue];
    rectStart_PROPER.origin.y = self.view.frame.size.height;

    UIView *vwUnderlay = [self.view viewWithTag:8080];
    if (vwUnderlay) {
        [vwUnderlay removeFromSuperview];
    }

    vwUnderlay = [[UIView alloc] init];
    [vwUnderlay setFrame:rectStart_PROPER];
    [vwUnderlay setBackgroundColor:[UIColor orangeColor]];
    [vwUnderlay setTag:8080];
    [self.view addSubview:vwUnderlay];

    [UIView animateWithDuration:[note.userInfo[UIKeyboardAnimationDurationUserInfoKey] floatValue]
                          delay:0

                     }
                     completion:nil];
