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 }

View Code

　　　　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 }

View Code

　　　　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 }

View Code

　　　　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 }

View Code

　　四.到此效果实现完毕，下面是效果图：
