iOS引导页

每个客户端都会有自己的引导页,启动app时,通过引导页简单介绍客户端的个性化功能。

好了废话不多说,直接上代码:

AppDelegate.h文件:

#import "AppDelegate.h"#import "GuideVC.h"#import "ViewController.h"@interface AppDelegate ()@end@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // Override point for customization after application launch.    ViewController *vc = [[ViewController alloc] init];        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];        if([GuideVC everLaunched] == NO)//启动引导页    {        GuideVC *tGV = [[GuideVC alloc]init];        self.window.rootViewController = tGV;        [self.window makeKeyAndVisible];        return YES;    }else{        self.window.rootViewController = vc;    }    [self.window makeKeyAndVisible];        return YES;}

GuideVC.m代码:

#import "GuideVC.h"#import "AppDelegate.h"#import "ViewController.h"#define Main_Screen_Width [UIScreen mainScreen].bounds.size.width#define Main_Screen_Height [UIScreen mainScreen].bounds.size.height#define totalCounts 7  //引导页数量#define EVER_LAUNCHED @"GuideVC_EVER_LAUNCHED"@interface GuideVC ()<UIScrollViewDelegate>@property (strong, nonatomic)  UIScrollView *pageScroll;@property (strong, nonatomic)  UIPageControl *pageControl;@end@implementation GuideVC- (void)viewDidLoad {    [super viewDidLoad];    [[NSUserDefaults standardUserDefaults]setBool:YES forKey:EVER_LAUNCHED];    [[NSUserDefaults standardUserDefaults]synchronize];    [self createScrollView];}/** *  创建显示引导图片ScrollView */-(void)createScrollView{            self.pageScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, Main_Screen_Width, Main_Screen_Height)];    self.pageScroll.pagingEnabled = YES;    self.pageScroll.delegate = self;    self.pageScroll.contentSize = CGSizeMake(Main_Screen_Width * totalCounts, Main_Screen_Height);    self.pageScroll.backgroundColor = [UIColor groupTableViewBackgroundColor];    self.pageScroll.showsHorizontalScrollIndicator = NO;    self.pageScroll.showsVerticalScrollIndicator = YES;    [self.view addSubview:self.pageScroll];        /** 添加引导图片 */    [self AddGuideImg];        CGFloat w = 100;    CGFloat h = 20;    self.pageControl = [[UIPageControl alloc]init];    [self.pageControl setFrame:CGRectMake((Main_Screen_Width-w)/2, Main_Screen_Height-30, w, h)];    self.pageControl.numberOfPages = totalCounts;  //设置引导页有几个界面    self.pageControl.currentPage = 0;    self.pageControl.tintColor = [UIColor lightGrayColor];    [self.view addSubview:self.pageControl];    }/** *  添加引导图片 */-(void)AddGuideImg{    for (int i=0; i<totalCounts; i++) {        UIImageView* imageView = [[UIImageView alloc] initWithFrame:CGRectMake(i*Main_Screen_Width, 0, Main_Screen_Width, Main_Screen_Height)];        NSString* imageNameStr =[NSString stringWithFormat:@"Guide%i.jpg",i+1];//设置引导页图片        imageView.image = [UIImage imageNamed:imageNameStr];                if (i == totalCounts-1) {            /** 最后一张图片添加按钮 */            [imageView setUserInteractionEnabled:YES];            UIButton* start = [UIButton buttonWithType:UIButtonTypeCustom];            UIImage* startBtnImg = [UIImage imageNamed:@"btn"];            [start setImage:startBtnImg forState:UIControlStateNormal];                        [start setFrame:CGRectMake(20,Main_Screen_Height-100,Main_Screen_Width - 20*2,60)];            start.layer.borderWidth = 5;            start.layer.borderColor = [UIColor whiteColor].CGColor;            [start setTitle:@"朕已阅" forState:UIControlStateNormal];                        [start addTarget:self action:@selector(gotoMainView) forControlEvents:             UIControlEventTouchUpInside];            [imageView addSubview:start];                    }        [self.pageScroll addSubview:imageView];    }    }/** 跳转到首页(登录页) */-(void)gotoMainView{    ViewController *vc = [[ViewController alloc] init];    [self presentViewController:vc animated:YES completion:nil];}#pragma mark - UIScrollViewDelegate#pragma mark-(void)scrollViewDidScroll:(UIScrollView *)scrollView{    CGFloat pageWidth = self.view.frame.size.width;    int page = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;    self.pageControl.currentPage = page;}+(BOOL)everLaunched{    return [[NSUserDefaults standardUserDefaults]boolForKey:EVER_LAUNCHED];}
