iOS实现简单的抽屉效果
作者：青玉伏案
说到抽屉效果在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，本文用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：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//获取主视图的导航控制器
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"NavigationController"];
//新建PPRevealSideViewController,并设置根视图（主页面的导航视图）
PPRevealSideViewController *sideViewController = [[PPRevealSideViewController alloc] initWithRootViewController:vc];
sideViewController.fakeiOS7StatusBarColor = [UIColor whiteColor];
//把sideViewController设置成根视图控制器
self.window.rootViewController = sideViewController;
[self.window makeKeyAndVisible];
return YES;
}
3.在主界面使用PPRevealSideViewController来推出导航页
- (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.在导航页点击不同的按钮使用PPRevealSideViewController跳转到不同的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.各个页面返回到主界面的代码如下：
- (IBAction)tapPage:(id)sender {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
UIViewController *view = [storyboard instantiateViewControllerWithIdentifier:@"NavigationController"];
[self.revealSideViewController popViewControllerWithNewCenterController:view animated:YES];
}
四、到此效果实现完毕，下面是效果图：
