Appdalagate.h方法中
#import "AppDelegate.h"

#import "CurtainViewController.h"

@implementation AppDelegate

@synthesize window=_window;

- (void)dealloc

{
    [_window release];

    [super dealloc];

}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

    // Override point for customization after application launch.
    //简介的设置了初始化,和对界面的权限的

    self.window.rootViewController=[[CurtainViewController alloc]init];

   // CurtainViewController *curtainViewcontroler=[[CurtainViewController alloc]initWithNibName:CurtainViewController bundle:nil];
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;

}

在CurtainViewController.h类中实现方法

#import "CurtainViewController.h"

#import "DemoViewControler.h"

#import "UIViewController+RECurtainViewController.h"

                    //类别类似是(要继承的类名和新生成的类名)

@interface CurtainViewController ()

@end

@implementation CurtainViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {
        //对背景的设置如果是真为设置为11.jpg 假为其他的颜色

        self.view.backgroundColor=UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone?
        [UIColor colorWithPatternImage:[UIImage imageNamed:@"11.jpg"]]:[UIColor grayColor];
        //按钮的位置的设置点击事件和显示
        UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame=CGRectMake((self.view.frame.size.width-200)/2,self.view.frame.size.height/2-30,200,44);

        [button setTitle:@"水平" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(dismisshorizontalPressed) forControlEvents:UIControlEventTouchUpInside];

        [self.view addSubview:button];

        //水平的方法的

        button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

        button.frame = CGRectMake((self.view.frame.size.width - 200) / 2, self.view.frame.size.height / 2 + 30, 200, 44);
        [button setTitle:@"Dismiss Vertical" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(dismissVerticalPressed) forControlEvents:UIControlEventTouchUpInside];

        [self.view addSubview:button];
    }
    return self;
}

//事件发生要调用的界面初始化和调用重构的方法

-(void)dismisshorizontalPressed{

DemoViewControler *test=[[DemoViewControler alloc]init];

    [self curtainRevealViewController:test transitionStyle:RECurtainTransitionHorizontal];
}

- (void)dismissVerticalPressed

//水平的方法的事件处理

{
       UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:[[UITableViewController alloc] initWithStyle:UITableViewStyleGrouped]];

    [self curtainRevealViewController:nav transitionStyle:RECurtainTransitionVertical];
}

在DemoViewControler.m 中实现的方法

#import "DemoViewControler.h"
#import "CurtainViewController.h"
#import "UIViewController+RECurtainViewController.h"
@interface DemoViewControler ()

@end

@implementation DemoViewControler

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self) {

        //初始化进入第二个界面的背景和按钮的设置按钮的点击事件

        UIImageView *backgroundimage=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"22.jpg"]];

        [self.view addSubview:backgroundimage];

               UIButton *button
        =[UIButton buttonWithType:UIButtonTypeRoundedRect ];
        button.frame=CGRectMake((self.view.frame.size.width-200)/2, self.view.frame.size.height/2-20, 200, 44);

        [button setTitle:@"Test Button" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(pressbutton) forControlEvents:UIControlEventTouchUpInside];

        [self.view addSubview:button];
// Custom initialization
    }
    return self;

}

-(void)pressbutton{

    //按钮的点击的事件第二界面的初始化并调用重构的方法
    CurtainViewController *test = [[CurtainViewController alloc] init];

    [self curtainRevealViewController:test transitionStyle:RECurtainTransitionHorizontal];
}

//屏幕是否可以旋转'

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
