引导页实现

Demo下载链接地址：https://github.com/tryingx/iPhone-IntroductionTutorial

1.把下载的demo中的

MYIntroductionView.h    

MYIntroductionView.m

MYIntroductionPanel.h

MYIntroductionPanel.m

这四个文件，再加上一些图像资源加到你的工程中去。（之后如果要修改图像等资源只要在相应位置修改就好了。）。

2.在你的主界面(打开应用显示的第一个界面)

在对应的.h文件中引入头文件并且设置协议。

如我的是  mainView.h 

 1 //  
 2 //  mainView.h  
 3 //  softwareApp  
 4 //  
 5 //  Created by *** on 13-9-27.  
 6 //  Copyright (c) 2013年 ***. All rights reserved.  
 7 //  
 8   
 9 #import <UIKit/UIKit.h>  
10 #import "MYIntroductionView.h"  
11   
12 @interface mainView : UITabBarController<MYIntroductionDelegate>  
13   
14 @end

3.在主界面对应的.m文件中加入如下代码。

如我的mainView.m 

 1 -(void)viewWillAppear:(BOOL)animated{  
 2       
 3     //读取沙盒数据  
 4     NSUserDefaults * settings1 = [NSUserDefaults standardUserDefaults];  
 5     NSString *key1 = [NSString stringWithFormat:@"is_first"];  
 6     NSString *value = [settings1 objectForKey:key1];  
 7     if (!value)  //如果没有数据  
 8     {  
 9         //STEP 1 Construct Panels  
10         MYIntroductionPanel *panel = [[MYIntroductionPanel alloc] initWithimage:[UIImage imageNamed:@"SampleImage1"] description:@"Welcome to MYIntroductionView, your 100 percent customizable interface for introductions and tutorials! Simply add a few classes to your project, and you are ready to go!"];  
11           
12         //You may also add in a title for each panel  
13         MYIntroductionPanel *panel2 = [[MYIntroductionPanel alloc] initWithimage:[UIImage imageNamed:@"SampleImage2"] title:@"Your Ticket!" description:@"MYIntroductionView is your ticket to a great tutorial or introduction!"];  
14           
15         //STEP 2 Create IntroductionView  
16           
17         /*A standard version*/  
18         //MYIntroductionView *introductionView = [[MYIntroductionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) headerImage:[UIImage imageNamed:@"SampleHeaderImage.png"] panels:@[panel, panel2]];  
19           
20           
21         /*A version with no header (ala "Path")*/  
22         //MYIntroductionView *introductionView = [[MYIntroductionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) panels:@[panel, panel2]];  
23           
24         /*A more customized version*/  
25         MYIntroductionView *introductionView = [[MYIntroductionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) headerText:@"MYIntroductionView" panels:@[panel, panel2] languageDirection:MYLanguageDirectionLeftToRight];  
26         [introductionView setBackgroundImage:[UIImage imageNamed:@"SampleBackground"]];  
27           
28         //Set delegate to self for callbacks (optional)  
29         introductionView.delegate = self;  
30           
31         //STEP 3: Show introduction view  
32         [introductionView showInView:self.view];  
33           
34         //写入数据  
35         NSUserDefaults * setting = [NSUserDefaults standardUserDefaults];  
36         NSString * key = [NSString stringWithFormat:@"is_first"];  
37         [setting setObject:[NSString stringWithFormat:@"false"] forKey:key];  
38         [setting synchronize];  
39     }  
40 }

　　viewWillAppear是在视图即将显示时候调用的方法。 这里看头寻找沙盒中 is_first中是否有数据，如果没有，就说明是第一次运行程序，则显示引导页并且在沙盒对应位置写入数据。

　　如果有数据，就说明不是第一次运行，则跳过，不显示引导页。
