在項目開發中使用iOS自帶的導航，因為其樣式修改起來比較麻煩，這裡我自己寫了一個類似的切換方式。我自己覺得還挺好用的，可能是因為代碼是自己寫的吧。。

先把代碼附上：

        } completion:^(BOOL finished) {

        }];
        
    }
    
    self.m_nCurrentViewControllerID = aViewControllersId;
}

-(void)popViewController:(EnViewControllersId) aViewControllersId

    NSString* pStrNewKeyOfViewControllerId = [NSString stringWithFormat:@"%d",aViewControllersId];
    
    if (pStrCurrentKeyOfViewControllerId == nil) {

    }
    else
    {

        } completion:^(BOOL finished) {
            [pCurrentViewController.view removeFromSuperview];
            
        }];
        
    }
    
    self.m_nCurrentViewControllerID = aViewControllersId;
}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

以上就是實現的代碼。

用法就是直接繼承，先使用

//存儲視圖控制器的方法

-(void)saveViewController:(UIViewController *) aUIViewController

ToDic:(EnViewControllersId) aViewControllersId;

方法將視圖控制器保存。

之後就可以用：

//推下向下一級視圖控制器
-(void)pushViewcController:(EnViewControllersId) aViewControllersId;
//返回上一級視圖控制器
-(void)popViewController:(EnViewControllersId) aViewControllersId;

兩個方法切換視圖控制器了。
