iOS引导页面（点击进入主界面的）

首先定义几个全局属性

{
UIScrollView *scroll;//滚动视图
NSArray *imgarr;//图片数组
UIPageControl *page;//分页
}

在viewDidLoad里:

//创建滚动视图
scroll = [[UIScrollView alloc]initWithFrame:self.view.frame];
//代理
scroll.delegate = self;
//添加到视图
[self.view addSubview:scroll];
//图片数组
imgarr = @[@"1",@"2",@"3",@"4"];//添加图片
//for循环添加图片
for (int i = 0; i < imgarr.count; i++)
{
//创建图片框
UIImageView *imgview = [[UIImageView alloc]initWithFrame:CGRectMake(self.view.frame.size.width *i, 0, self.view.frame.size.width, self.view.frame.size.height)];
//设置图片
imgview.image = [UIImage imageNamed:imgarr[i]];
//是否与用户交互
imgview.userInteractionEnabled = YES;
//判断，最后一张图片就添加按钮
if (i == 3)
{
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
//设置按钮位置
btn.frame = CGRectMake((self.view.frame.size.width - 100)/2, 600, 100, 44);
//按钮文字
[btn setTitle:@"立即体验" forState:UIControlStateNormal];
//注册监听事件
[btn addTarget:self action:@selector(click) forControlEvents:UIControlEventTouchDown];
//设置圆角
btn.layer.cornerRadius = 8;
//裁剪
btn.layer.masksToBounds = YES;
//背景颜色
btn.backgroundColor = [UIColor blueColor];
//添加到视图
[imgview addSubview:btn];
}
//添加到滚动视图
[scroll addSubview:imgview];
}
//设置吧滚动范围
scroll.contentSize = CGSizeMake(self.view.frame.size.width *imgarr.count, self.view.frame.size.height);
//设置分页效果
scroll.pagingEnabled = YES;
//去除弹窗效果
scroll.bounces = NO;
//隐藏水平滚动条
scroll.showsHorizontalScrollIndicator = NO;
//创建分页控件
page = [[UIPageControl alloc]initWithFrame:CGRectMake((self.view.frame.size.width)-100, 650, 100, 30)];
//设置分页个数
page.numberOfPages = imgarr.count;

//隐藏tabbar和navigation
self.navigationController.navigationBar.hidden = YES;
self.tabBarController.tabBar.hidden = YES;

在下面点击事件:

-(void)click{

//取消隐藏tabbar和navigation
self.navigationController.navigationBar.hidden = NO;
self.tabBarController.tabBar.hidden = NO;

//在里面写内容

}
