說到抽屜效果在iOS中比較有名的第三方類庫就是PPRevealSideViewController。一說到第三方類庫就自然而然的想到我們的CocoaPods，本文用CocoaPods引入PPRevealSideViewController,然后在我們的工程中以代碼結合storyboard來做出抽屜效果。

一、在工程中用CocoaPods引入第三方插件PPRevealSideViewController.

(1).在終端中搜索PPRevealSideViewController的版本

(2).在Podfile中添加相應的版本庫

(3).之后保存一下Podfile文件，然后執行pod install即可

二、為我們的工程添加pch文件

因為用的是XCode6, 上面默認是沒有pch文件的，如果我們想使用pch文件，需要手動添加，添加步驟如下

1.在XCode6中是么有pch文件的，如下圖

2.創建pch文件

3.配置pch文件

(1)、找工程的Targets->Build Settings->Apple LLVM 6.0 - Language

(2)在Prefix Header下面的Debug和Release下添加$(SRCROOT)/工程名/pch文件，入下圖

三、使用PPRevealSideViewController來實現抽屜效果

當然了首先在pch文件中引入我們的第三方類庫，然后使用即可

1.在storyboard拖出來我們要用的視圖控制器，點擊主界面上的按鈕會以抽屜的形式展示出導航頁，然后在導航頁導航到各個界面，之后在從各個頁面回到主界面

2.在AppDelegate中初始化我們的PPRevealSideViewController并設置為啟動頁面代碼如下：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch.  self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];  //獲取主視圖的導航控制器 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"NavigationController"];  //新建PPRevealSideViewController,并設置根視圖（主頁面的導航視圖） PPRevealSideViewController *sideViewController = [[PPRevealSideViewController alloc] initWithRootViewController:vc];  sideViewController.fakeiOS7StatusBarColor = [UIColor whiteColor];  //把sideViewController設置成根視圖控制器 self.window.rootViewController = sideViewController;  [self.window makeKeyAndVisible];  return YES;}

3.在主界面使用PPRevealSideViewController來推出導航頁

- (IBAction)tapItem:(id)sender {  UIStoryboard *storybaord = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; UITableViewController *table = [storybaord instantiateViewControllerWithIdentifier:@"CustomViewViewController"]; [self.revealSideViewController pushViewController:table onDirection:PPRevealSideDirectionLeft animated:YES];}

4.在導航頁點擊不同的按鈕使用PPRevealSideViewController跳轉到不同的controller

- (IBAction)tap1:(id)sender {  UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"one"]; [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];}- (IBAction)tap2:(id)sender {  UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"two"]; [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES]; }- (IBAction)tap3:(id)sender { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"three"]; [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];}- (IBAction)tap4:(id)sender { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"four"]; [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];}

5.各個頁面返回到主界面的代碼如下：

- (IBAction)tapPage:(id)sender { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];  UIViewController *view = [storyboard instantiateViewControllerWithIdentifier:@"NavigationController"];  [self.revealSideViewController popViewControllerWithNewCenterController:view animated:YES];}

四、到此效果實現完畢，下面是效果圖：
