how could i pop to root controller?

[cs13886]

I write a categary for FlipBoardNavigationController . So it has two new function

1. -(void)popToViewController:(UIViewController*)toViewController; you can use this pop to any controller in FlipBoardNavigationController.viewcontrollers

2-(void)popToRootViewController; you can easy pop to the root viewcontroller

***************FlipBoardNavigationController.h *** // FlipBoardNavigationController+extention.h // // Created by CHEN on 14-3-19. //

#import "FlipBoardNavigationController.h"

@interface FlipBoardNavigationController (extention)

-(void)popToViewController:(UIViewController*)toViewController; -(void)popToRootViewController;

@end

***************FlipBoardNavigationController.h end ***

***************FlipBoardNavigationController.m *** // // FlipBoardNavigationController+extention.m // // Created by CHEN on 14-3-19. //

#import "FlipBoardNavigationController+extention.h" #import <FlipBoardNavigationController.h>

@implementation FlipBoardNavigationController (extention)

-(void)popToViewController:(UIViewController*)toViewController{

NSMutableArray *controllers = self.viewControllers;
NSInteger index = [controllers indexOfObject:toViewController];
UIViewController *needRemoveViewController;

for (int i = controllers.count - 2; i >index; i--) {

    needRemoveViewController = [controllers objectAtIndex:i];
    [needRemoveViewController.view setAlpha:0];

    [needRemoveViewController removeFromParentViewController];
    [controllers removeObject:needRemoveViewController];
}

[self popViewController];

}

-(void)popToRootViewController{ UIViewController *rootController = [self.viewControllers objectAtIndex:0]; [self popToViewController:rootController]; }

************_FlipBoardNavigationController.m end_
