只有第一次進入帶導航視圖

只有第一次運行程式才出現 ，刪除重新運行程式才會有。

我只展示最後一張圖了。

首先創建一個viewcontroller的類

然後在APPDelegate中設為根視圖

然後在

UseGuideViewController.h中寫

FirstViewController是我的主界面。

 巨集定義寬和高

#import <UIKit/UIKit.h>
#import "FirstViewController.h"
#define WIDTH  self.view.frame.size.width
#define HEIGHT self.view.frame.size.height

@interface UseGuideViewController : UIViewController<UIScrollViewDelegate>

@end

 下麵的就是UseGuideViewController.m中的代碼 ，有一些註釋。

#import "UseGuideViewController.h"

@interface UseGuideViewController ()

@end

@implementation UseGuideViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self initGuide];
}

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

         [scrollView setContentSize:CGSizeMake(WIDTH*4, 0)];

         //    [scrollView setBounces:NO]; //避免彈跳效果,避免把根視圖露出來

 好了， 這個就是我簡單的介紹了。或許不成熟， 但我為之努力。
