只有第一次运行程序才出现 ，删除重新运行程序才会有。
我只展示最后一张图了。
首先创建一个viewcontroller的类
然后在APPDelegate中设为根视图
然后在
UseGuideViewController.h中写
FirstViewController是我的主界面。
宏定义宽和高
#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
下面的就是UseGuideViewController.m中的代码 ，有一些注释。
#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.}-(void)initGuide{ UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT)]; [scrollView setContentSize:CGSizeMake(WIDTH*4, 0)]; [scrollView setPagingEnabled:YES]; //视图整页显示 // [scrollView setBounces:NO]; //避免弹跳效果,避免把根视图露出来 scrollView.delegate=self; UIImageView *imageview = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT)]; [imageview setImage:[UIImage imageNamed:@"5.png"]]; [scrollView addSubview:imageview]; UIImageView *imageview1 = [[UIImageView alloc] initWithFrame:CGRectMake(WIDTH, 0, WIDTH, HEIGHT)]; [imageview1 setImage:[UIImage imageNamed:@"004.png"]]; [scrollView addSubview:imageview1]; UIImageView *imageview2 = [[UIImageView alloc] initWithFrame:CGRectMake(WIDTH*2, 0, WIDTH, HEIGHT)]; [imageview2 setImage:[UIImage imageNamed:@"006.png"]]; [scrollView addSubview:imageview2]; UIImageView *imageview3 = [[UIImageView alloc] initWithFrame:CGRectMake(WIDTH*3, 0, WIDTH, HEIGHT)]; [imageview3 setImage:[UIImage imageNamed:@"0.png"]]; imageview3.userInteractionEnabled = YES; //打开imageview3的用户交互;否则下面的button无法响应 [scrollView addSubview:imageview3]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];//在imageview3上加载一个透明的button [button setTitle:nil forState:UIControlStateNormal]; [button setFrame:CGRectMake(250, 20, 150, 40)]; [button addTarget:self action:@selector(firstpressed) forControlEvents:UIControlEventTouchUpInside]; [button setTitle:@"进入主界面" forState:0]; [button setTitleColor:[UIColor colorWithRed:0.305 green:1.000 blue:0.901 alpha:1.000] forState:0]; [imageview3 addSubview:button]; [self.view addSubview:scrollView]; }- (void)firstpressed { FirstViewController *firstvc=[FirstViewController new]; [self presentViewController: firstvc animated:YES completion:^{ NSLog(@"页面切换完毕.模态视图"); }]; }/*#pragma mark - Navigation// In a storyboard-based application, you will often want to do a little preparation before navigation- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { // Get the new view controller using [segue destinationViewController]. // Pass the selected object to the new view controller.}*/@end好了， 这个就是我简单的介绍了。或许不成熟， 但我为之努力。
