UIKeyboard在iOS7中不会自动半透明 [英] UIKeyboard not automatically translucent in iOS7

问题描述

据我所知，在Xcode 5和iOS 7项目中进行开发时，与UITextField交互时弹出的键盘应该是半透明的，并通过背景中的任何颜色显示。在我的两个项目中都不是这种情况。我有一个彩色&模糊的背景，我希望通过键盘发现;但键盘仍然是默认的白色/灰色。

I understand that when developing in Xcode 5 with and iOS 7 project, the keyboard that pops up when interacting with a UITextField should be translucent and show through any colors in the background. This is not the case in both my projects. I have a colored & blurred background and I'm hoping for that to transpire through the keyboard; however the keyboard remains the default white/gray.

这就是我演示的内容：

UIColor *tintColor = [UIColor colorWithWhite:0.21 alpha:0.4];
UIColor *background = [[UIColor alloc] initWithPatternImage:[[UIImage imageNamed:@"universe.jpg"] applyBlurWithRadius:19
                                                                                                            tintColor:tintColor
                                                                                                saturationDeltaFactor:1.8
                                                                                                            maskImage:nil]];
self.view.backgroundColor = background;

UITextField *text = [[UITextField alloc] initWithFrame:CGRectMake(200, 200, 300, 60)];
[self.view addSubview:text];

我甚至尝试将键盘外观类型设置为UIKeyboardAppearanceDefault和UIKeyboardAppearanceLight

I have even tried to set the keyboard appearance type to both UIKeyboardAppearanceDefault and UIKeyboardAppearanceLight

有人可以指导/告诉我如何实现键盘半透明效果？这应该是自动的吗？
谢谢

Can someone please guide/tell me on how can I achieve the keyboard translucent effect? Should this be automatic? Thanks

推荐答案

我构建了一个简单的应用程序来测试以试图找到这个问题，但我除了将IPHONEOS_DEPLOYMENT_TARGET设置为较低的版本号（如6.0），然后在iOS 6.0上运行之外，它已无法复制它。在所有情况下，在所有iOS 7设备和模拟器上，默认键盘下面的内容都是半透明的模糊。

I built a simple app to test to try to find this issue, but I've been unable to replicate it except by setting IPHONEOS_DEPLOYMENT_TARGET to a lower version number like 6.0, then running on iOS 6.0. In all cases, on all iOS 7 devices and simulator, the default keyboard has a translucent blur of the content underneath it.

也许你可以分享图片或样本项目？
