有没有办法在iOS 7中禁用键盘上的透明度？ [英] Is there a way to disable transparency on the keyboard in iOS 7?

问题描述

我想要一个带有非透明键盘的键盘 - 我无法使用任何支持的UIKeyboardTypes。还有另一种解决方法吗？

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颜色覆盖键盘下的背景视图 - 是否有一种很好的方法来设置背景动画与键盘显示动画同步查看？

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?

推荐答案

当在Xcode 5中使用Base编译应用程序时，iOS7中的键盘是半透明的iOS 7的SDK。

如果您在Xcode 4.6.x上构建应用程序，您将拥有与之前一样的非半透明键盘。

（我知道这是一个糟糕的修复但是，我认为我建议它）

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)

无论如何，你可以尝试使用默认的键盘通知：

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

1. UIKeyboardWillShowNotification


2. UIKeyboardWillHideNotification

1. UIKeyboardWillShowNotification
2. UIKeyboardWillHideNotification

应该是这样的：

-(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
                        options:[note.userInfo[UIKeyboardAnimationCurveUserInfoKey] integerValue] << 16
                     animations:^{
                         [vwUnderlay setFrame:CGRectOffset(vwUnderlay.frame, 0, -vwUnderlay.frame.size.height)];
                     }
                     completion:nil];
