iOS开发之抽屉效果实现
说道抽屉效果在iOS中比较有名的第三方类库就是PPRevealSideViewController。一说到第三方类库就自然而然的想到我们的CocoaPods，今天的博客中用CocoaPods引入PPRevealSideViewController,然后在我们的工程中以代码结合storyboard来做出抽屉效果。
一.在工程中用CocoaPods引入第三方插件PPRevealSideViewController.
(1).在终端中搜索PPRevealSideViewController的版本
(2).在Podfile中添加相应的版本库
(3).之后保存一下Podfile文件，然后执行pod install即可
二、为我们的工程添加pch文件
因为用的是XCode6, 上面默认是没有pch文件的，如果我们想使用pch文件，需要手动添加，添加步骤如下
1.在XCode6中是么有pch文件的，如下图
2.创建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，入下图
三、使用PPRevealSideViewController来实现抽屉效果
当然了首先在pch文件中引入我们的第三方类库，然后使用即可
1.在storyboard拖出来我们要用的视图控制器，点击主界面上的按钮会以抽屉的形式展示出导航页，然后在导航页导航到各个界面，之后在从各个页面回到主界面
2.在AppDelegate中初始化我们的PPRevealSideViewController并设置为启动页面代码如下：
1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
2 // Override point for customization after application launch.
3
4 self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
5
6 //获取主视图的导航控制器
7 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
8 UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"NavigationController"];
9
10 //新建PPRevealSideViewController,并设置根视图（主页面的导航视图）
11 PPRevealSideViewController *sideViewController = [[PPRevealSideViewController alloc] initWithRootViewController:vc];
12
13 sideViewController.fakeiOS7StatusBarColor = [UIColor whiteColor];
14
15 //把sideViewController设置成根视图控制器
16 self.window.rootViewController = sideViewController;
17
18 [self.window makeKeyAndVisible];
19
20 return YES;
21 }3.在主界面使用PPRevealSideViewController来推出导航页
1 - (IBAction)tapItem:(id)sender {
2
3 UIStoryboard *storybaord = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
4 UITableViewController *table = [storybaord instantiateViewControllerWithIdentifier:@"CustomViewViewController"];
5 [self.revealSideViewController pushViewController:table onDirection:PPRevealSideDirectionLeft animated:YES];
6 }4.在导航页点击不同的按钮使用PPRevealSideViewController跳转到不同的controller
1 - (IBAction)tap1:(id)sender {
2 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
3 UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"one"];
4 [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];
5 }
6
7 - (IBAction)tap2:(id)sender {
8
9 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
10 UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"two"];
11 [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];
12
13 }
14
15 - (IBAction)tap3:(id)sender {
16 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
17 UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"three"];
18 [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];
19 }
20
21 - (IBAction)tap4:(id)sender {
22 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
23 UIViewController *one = [storyboard instantiateViewControllerWithIdentifier:@"four"];
24 [self.revealSideViewController popViewControllerWithNewCenterController:one animated:YES];
25 }5.各个页面返回到主界面的代码如下：
1 - (IBAction)tapPage:(id)sender {
2 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
3
4 UIViewController *view = [storyboard instantiateViewControllerWithIdentifier:@"NavigationController"];
5
6 [self.revealSideViewController popViewControllerWithNewCenterController:view animated:YES];
7 }四.到此效果实现完毕，下面是效果图：
