iOS8 键盘困惑，为什么会触发 Root View 的hitTest 方法？

Question

当触摸键盘区域时，触发根 View 的方法:

(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event

我很困惑，有人可以帮助我吗？

Answer 1

在 AppDelegate 的 applicationWillEnterForeground 中，放置此代码。
它对我有用，特别是 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;
    }
}];}
