报错```Attempt to present <UIAlertController: 0x7f8d50193c00> on
<UINavigationController: 0x7f8d4f022000> whose view is not in the window
hierarchy!```
## Problem
当我presentViewController出来一个WXBaseViewController时候，进行alert弹框会报错
报错```Attempt to present <UIAlertController: 0x7f8d50193c00> on
<UINavigationController: 0x7f8d4f022000> whose view is not in the window
hierarchy!```
### What is expected to happen?
在类CDVWKWebViewUIDelegate中
```
UIViewController* rootController = [UIApplication
sharedApplication].delegate.window.rootViewController;
[rootController presentViewController:alert animated:YES completion:nil];
```
会有问题，
是否考虑修改为
```
UIViewController* rootController = [UIApplication
sharedApplication].delegate.window.rootViewController;
if ([rootController isKindOfClass:[UINavigationController class]]) {
rootController = [(UINavigationController *)rootController
visibleViewController];
}
[rootController presentViewController:alert animated:YES completion:nil];
```
