如果是在Controller中则代码如下

-(void)backClick{
    
    UIViewController *vc =  self;
    while (vc.presentingViewController) {
        vc = vc.presentingViewController;
    }
    [vc dismissViewControllerAnimated:YES completion:nil];
    
}

如果实在视图(View)中则代码如下

-(void)backClick{
    
    UIViewController *vc =  [self viewController];
    while (vc.presentingViewController) {
        vc = vc.presentingViewController;
    }
    [vc dismissViewControllerAnimated:YES completion:nil];
    
    
    
}
/** 获取当前view的controller */
- (UIViewController *)viewController
{
    for (UIView *next = [self superview]; next; next = next.superview) {
        UIResponder *nextResponser = [next nextResponder];
        
        if ([nextResponser isKindOfClass:[UIViewController class]]) {
            return (UIViewController *)nextResponser;
        }
    }
    return nil;
}

该代码可返回到根(通过present过来的)Controller
