ios 极光推送获取当前控制器进行界面跳转

#pragma mark - 通过推送返回的数据决定跳转到那个页面
- (void)JPushjudgeToWhichVC{
    if ([self.type isEqualToString:@"1"]) {
        //外链和APP内活动页
        KindDetailViewController * KindVC = [[KindDetailViewController alloc] init];
        KindVC.url = self.redirect;
        [[self getCurrentVC] presentViewController:KindVC animated:YES completion:nil];
        
    }
}

#pragma mark - 获取当前的显示的控制器
- (UIViewController *)getCurrentVC{

    UIViewController *currVC = nil;
    UIViewController *rootvc = self.window.rootViewController;
    do {
        if ([Rootvc isKindOfClass:[UINavigationController class]]) {//控制器为UINavigationController
            UINavigationController *nav = (UINavigationController *)rootvc;
            UIViewController *vc = [nav.viewControllers lastObject];
            currVC = vc;
            rootvc = vc.presentedViewController;
            
        }else if ([Rootvc isKindOfClass:[UITabBarController class]]){//控制器为UITabBarController
            UITabBarController *tabVC = (UITabBarController *)rootvc;
            currVC = tabVC ;
            rootvc = [tabVC.viewControllers objectAtIndex:tabVC.selectedIndex];
            continue;
        }else {//控制器为UIViewController
            UIViewController *VC = (UIViewController *)rootvc;
            currVC = VC;
            Rootvc = VC.presentedViewController;
        }
    } while (Rootvc != nil);
    return currVC;
}
