推荐答案
这可以在 WKWebView中实现
使用该方法的变体在 UIWebView
上调出 inputAccessoryView
。
This is possible in WKWebView
with a variant of the method for swizzling out the inputAccessoryView
on UIWebView
.
首先,添加这个小类:
@interface _NoInputAccessoryView : NSObject
@end
@implementation _NoInputAccessoryView
- (id)inputAccessoryView {
return nil;
}
@end
接下来,添加此方法:
Next, add this method:
- (void)removeInputAccessoryViewFromWKWebView:(WKWebView *)webView {
UIView *targetView;
for (UIView *view in webView.scrollView.subviews) {
if([[view.class description] hasPrefix:@"WKContent"]) {
targetView = view;
}
}
if (!targetView) {
return;
}
NSString *noInputAccessoryViewClassName = [NSString stringWithFormat:@"%@_NoInputAccessoryView", targetView.class.superclass];
Class newClass = NSClassFromString(noInputAccessoryViewClassName);
if(newClass == nil) {
newClass = objc_allocateClassPair(targetView.class, [noInputAccessoryViewClassName cStringUsingEncoding:NSASCIIStringEncoding], 0);
if(!newClass) {
return;
}
Method method = class_getInstanceMethod([_NoInputAccessoryView class], @selector(inputAccessoryView));
class_addMethod(newClass, @selector(inputAccessoryView), method_getImplementation(method), method_getTypeEncoding(method));
objc_registerClassPair(newClass);
}
object_setClass(targetView, newClass);
}
然后,您只需调用该方法并传入 WKWebView
:
Then all you have to do is call that method and pass in your WKWebView
:
[self removeInputAccessoryViewFromWKWebView:webView];
注意:我还不确定这是否会通过应用审核,但它是非常类似于我用于 UIWebView
的相同代码,并确实通过了审核。
Note: I do not yet know for sure if this will pass app review, but it is extremely similar to the same code I used for UIWebView
, and that did pass review.
更新:此代码位于已通过App Store审核的应用中。
Update: This code is in an app that has passed App Store review.
