(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
I am very confused，anyone can help me？

Answer 1

In your applicationWillEnterForeground in AppDelegate, put this code.
It works for me, specially with KLCPopup
- (void)applicationWillEnterForeground:(UIApplication *)application{
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
if (!IS_OS_8_OR_LATER) return;
[UIApplication.sharedApplication.windows enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(UIWindow *w, NSUInteger idx, BOOL *stop) {
if (!w.opaque && [NSStringFromClass(w.class) hasPrefix:#"UIText"]) {
// The keyboard sometimes disables interaction. This brings it back to normal.
BOOL wasHidden = w.hidden;
w.hidden = YES;
w.hidden = wasHidden;
*stop = YES;
}
}];}

Answer 2

This problem will appear in：
1、you changed keywindow‘s rootViewController;
2、enter background and return to the foreground;
So，restore UITextEffectsWindow can fixed it after your change everytime.
void TSRestoreKeyboardWindow(void)
{
if (!TSSystemVersionGreaterThanIOS8()) return;
[UIApplication.sharedApplication.windows enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(UIWindow *w, NSUInteger idx, BOOL *stop) {
if (!w.opaque && [NSStringFromClass(w.class) hasPrefix:#"UIText"]) {
// The keyboard sometimes disables interaction. This brings it back to normal.
BOOL wasHidden = w.hidden;
w.hidden = YES;
w.hidden = wasHidden;
*stop = YES;
}
}];
}
