推荐答案

在深入研究Webkit源数周后，我已经设法通过调整来实现iOS 9的工作_startAssistingNode：userIsInteracting：blurPreviousNode：userObject on WKContentView 并覆盖userIsInteracting值：

After digging into the Webkit sources for a couple of weeks, I've managed to get this working on iOS 9 by swizzling _startAssistingNode:userIsInteracting:blurPreviousNode:userObject on WKContentView and overriding the userIsInteracting value:

伪代码：

swizzle_intercept("WKContentView", "_startAssistingNode:userIsInteracting:blurPreviousNode:userObject:", &hackAssist);

void hackAssist (id self, SEL _cmd, void* arg0, BOOL arg1, BOOL arg2, id arg3) {
    ((void (*)(id,SEL,void*,BOOL,BOOL,id))swizzle_interceptee(hackAssist))(self, _cmd, arg0, TRUE, arg2, arg3);
}

干杯！
