自定义Webview键盘问题 [英] Custom webview keyboard issues
问题描述
因此从该线程 UIWebView中的UIKeyboardAppearance 和TomSwift的很棒的答案，我得到了其中约99％的有效.
So adapting code form this thread UIKeyboardAppearance in UIWebView and TomSwift's awesome answer, I got about 99% of it working.
在iOS 7模拟器中，一切似乎都可以正常工作.但是，在iOS 8中，当键盘首次出现时，< >完成的栏是白色的.当我点击或选择其他输入时，它会更改为我指定的颜色.
In the iOS 7 simulator, everything appears to work just fine. However in iOS 8, when the keyboard first appears, the < > Done bar is white. When I tap or select another input, it changes to my specified color.
我的问题是，我该如何预防和/或更改该白色部分?
My question is, how can I prevent and or change that white portion?
其他线程中的所有代码都相同，除了我在键盘WillAppear中这样称呼的颜色.
All code in the other thread is identical, except for my color which I call like so in the keyboardWillAppear.
UIWindow *keyboardWindow = nil;
for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
if (![[testWindow class] isEqual : [UIWindow class]]) {
keyboardWindow = testWindow;
break;
}
}
// Locate UIWebFormView.
for (UIView *possibleFormView in [keyboardWindow subviews]) {
if ([[possibleFormView description] hasPrefix : @"<UIInputSetContainerView"]) {
for (UIView* peripheralView in possibleFormView.subviews) {
peripheralView.backgroundColor = [UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:0.75];
for (UIView* peripheralView_sub in peripheralView.subviews) {
peripheralView_sub.backgroundColor = [UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:0.75];
}
}
}
}
任何帮助将不胜感激.
推荐答案
因此，随着iOS 9+的发布，我发现它打破了上述方法.但是，经过一番修补并浏览了一些观点，我提出了以下我已经回答的内容的补充.
So with iOS 9+ out, I found it broke the mentioned methods. But with some tinkering and looking through some views, I came up with an addition to what i've already answered below.
现在，我决定放弃自定义颜色的东西，我只是在挖掘适合我的应用程序的黑色键盘.无论如何，这是对我有用的东西.在9.1 sim到7上进行了测试.也在我的6+运行9.0.2上进行了测试.
Now I've decided to ditch the custom color stuff, I'm digging just the black keyboard, suits my app. Anyways, here's what works for me. Tested on 9.1 sim to 7. Also on my 6+ running 9.0.2.
//Keyboard setting
@interface UIWebBrowserView : UIView
@end
@interface UIWebBrowserView (UIWebBrowserView_Additions)
@end
@implementation UIWebBrowserView (UIWebBrowserView_Additions)
- (id)inputAccessoryView {
return nil;
}
- (UIKeyboardAppearance) keyboardAppearance{
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
BOOL switchOn = [userDefaults boolForKey:@"darkKeyboard"];
if (switchOn) {
return UIKeyboardAppearanceDark;
}
else {
return UIKeyboardAppearanceDefault;
}
}
@end
@interface UITextInputTraits : UIWebBrowserView
@end
@interface UITextInputTraits (UIWebBrowserView)
@end
@implementation UITextInputTraits (UIWebBrowserView)
- (UIKeyboardAppearance) keyboardAppearance{
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
BOOL switchOn = [userDefaults boolForKey:@"darkKeyboard"];
if (switchOn) {
return UIKeyboardAppearanceDark;
}
else {
return UIKeyboardAppearanceDefault;
}
}
@end
我真的希望有人对这些答案有所帮助:D
I really hope somebody finds these answers helpful :D
更新的信息: 对完成的酒吧感到好奇，这是所有工作的开始.我重新启用它只是为了查看，并发现它将其更改为黑色.不错，尽管我放弃了它以隐藏滚动键盘.
UPDATED INFO: Was curious about the done bar, which is how this all got started. I re-enabled it just to see, and to find out it changed it to black. Nice bonus, although I've ditched it to hide the keyboard with scroll.
15年12月19日更新 因此，我决定从UIWebView过渡到WKWebView，只是发现显然两者之间存在差异.我设法使它再次工作.常规的UIKeyboardAppearanceDark调用会使键盘比我喜欢的更加透明.因此，我根据自己的喜好对其进行了修改.再说一次，可能不是标准的做事方式，但我不在乎，反正不会成功.
UPDATE 12/19/15 So I decided to make my transition from UIWebView to WKWebView, only to find out that obviously things are different between the two. I've managed to get it working again. Regular UIKeyboardAppearanceDark calls causes the keyboard to be more transparent than I like. So I modified it to my liking. Again, probably not the standard way of doing things, but I don't care, it's not going to apple anyways.
所有内容仍在AppDelegate中.
Everything is still being put in the AppDelegate.

我没有像以前一样设法找到一种隐藏inputAccessoryBar的方法，但是由于有了几个线程，我才能够正常工作.在我的视图控制器中，我调用:
I haven't managed to find a way to hide the inputAccessoryBar like I did before, but thanks to a couple threads I got it working. In my view controllers I call:
-(void)removeInputAccessoryView {
UIView* subview;
for (UIView* view in webView.scrollView.subviews) {
if([[view.class description] hasPrefix:@"WKContent"])
subview = view;
}
if(subview == nil) return;
NSString* name = [NSString stringWithFormat:@"%@SwizzleHelper", subview.class.superclass];
Class newClass = NSClassFromString(name);
if(newClass == nil)
{
newClass = objc_allocateClassPair(subview.class, [name cStringUsingEncoding:NSASCIIStringEncoding], 0);
if(!newClass) return;
Method method = class_getInstanceMethod([AppDelegate class], @selector(inputAccessoryView));
class_addMethod(newClass, @selector(inputAccessoryView), method_getImplementation(method), method_getTypeEncoding(method));
objc_registerClassPair(newClass);
}
object_setClass(subview, newClass);
}
然后在viewDidLoad中调用:
And in the viewDidLoad I call:
[self removeInputAccessoryView];
我计划进行更多修改，但就目前而言，这可以满足我的需要.
I plan on tinkering around some more, but for now, this works to what I need it to do.
