左右侧滑菜单功能的实现
左右侧滑功能是比较常见的效果,此实例实现如下的效果:
这边使用到的SlideNavigationController开源类(引入源代码中的Source),其为NavigationController子类,在运用程序AppDelegate就设置为其根视图;主要代码如下:
1:AppDelegate主要代码如下:
#import "AppDelegate.h" #import "SlideNavigationController.h" #import "leftViewController.h" #import "rightViewController.h" #import "ViewController.h" - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; self.window.backgroundColor = [UIColor whiteColor];
//设置根导航视图 ViewController *homeVc = [[ViewController alloc] init]; [self.window setRootViewController:[[SlideNavigationController alloc] initWithRootViewController:homeVc]];
//设置左右视图 leftViewController* leftController=[[leftViewController alloc]init]; rightViewController* rightController=[[rightViewController alloc]init]; [SlideNavigationController sharedInstance].rightMenu = rightController; [SlideNavigationController sharedInstance].leftMenu = leftController; [SlideNavigationController sharedInstance].menuRevealAnimationDuration = .18; [self.window makeKeyAndVisible]; return YES; }
2:主页面ViewController代码:
#import <UIKit/UIKit.h> #import "SlideNavigationController.h" @interface ViewController : UIViewController<SlideNavigationControllerDelegate> @end
#import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor=[UIColor yellowColor]; self.title=@"首页"; UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 40, 30)]; [button setTitle:@"右边" forState:UIControlStateNormal]; [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [button addTarget:[SlideNavigationController sharedInstance] action:@selector(toggleRightMenu) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button]; [SlideNavigationController sharedInstance].rightBarButtonItem = rightBarButtonItem; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #pragma mark - SlideNavigationController Methods - - (BOOL)slideNavigationControllerShouldDisplayLeftMenu { return YES; } - (BOOL)slideNavigationControllerShouldDisplayRightMenu { return YES; } @end
注意要实现SlideNavigationControllerDelegate的两个是否有左跟右的菜单,还可以设置其导航栏的按键样式,如果没有设置会像左边出现的这种默认的;
3:左边视图leftViewController
#import <UIKit/UIKit.h> #import "SlideNavigationController.h" #import "OneViewController.h" #import "TwoViewController.h" @interface leftViewController : UIViewController<UITableViewDelegate, UITableViewDataSource> @end
#import "leftViewController.h" @interface leftViewController() @property(nonatomic,strong)UITableView *tableView; @property(strong,nonatomic) NSArray *listData;
@property(assign,nonatomic) bool slideOutAnimationEnabled;
@end @implementation leftViewController -(void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor=[UIColor redColor]; [self ininLoadTable]; } -(void)ininLoadTable { self.tableView=[[UITableView alloc]initWithFrame:self.view.frame style:UITableViewStylePlain]; self.tableView.delegate=self; self.tableView.dataSource=self; [self.view addSubview:self.tableView]; self.listData=[[NSArray alloc] initWithObjects:@"朋友圈",@"个人好友",@"最近联系人", nil]; } #pragma mark - UITableView Delegate & Datasrouce - - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return self.listData.count; } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 20)]; view.backgroundColor = [UIColor clearColor]; return view; } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { return 20; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"]; if (cell==nil) { cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"]; } cell.textLabel.text=self.listData[indexPath.row]; cell.backgroundColor = [UIColor clearColor]; return cell; } //跳转 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UIViewController *vc ; switch (indexPath.row) { case 0: vc = [[OneViewController alloc]init]; break; case 1: vc = [[TwoViewController alloc]init]; break; case 2: vc = [[OneViewController alloc]init]; break; case 3: [self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:YES]; [[SlideNavigationController sharedInstance] popToRootViewControllerAnimated:YES]; return; break; } [[SlideNavigationController sharedInstance] popToRootAndSwitchToViewController:vc withSlideOutAnimation:self.slideOutAnimationEnabled andCompletion:nil]; } @end
注意:这边主要是进行导航跳转时要注意,popToRootViewControllerAnimated跟popToRootAndSwitchToViewController
4:右边的rightViewController
#import "rightViewController.h" @implementation rightViewController -(void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor=[UIColor blueColor]; } @end
