每当用户点击外面的任何地方时，我都想隐藏侧边菜单。菜单出现了，但我找不到任何办法摆脱它。任何有关 hidesOnTap 的建议也将不胜感激。我还使用表格视图来显示侧边菜单内容，每当用户点击任何选项时，它都会被重定向到该页面。如何隐藏菜单而不进行任何选择。下面是代码

#import "MainMenuViewController.h"
#import "UIImageView+AFNetworking.h"
#import "ProfileViewController.h"
#import "ChatMenuHomeVC.h"


@interface MainMenuViewController ()
{
    NSString *username;
    NSString *profilestr;
}

@property (nonatomic, weak) IBOutlet UITableViewCell *cellMain;
@end

@implementation MainMenuViewController
@synthesize lblUserName,profilePic;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self)
    {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    //SideMenuToProfileView
    arrOfOptions = [[NSMutableArray alloc]init];

    [self addTitle:@"Home" imageName:@"icon-sidemenu-home.png" segueName:@"slidingToHome"];
    [self addTitle:@"My Chat" imageName:@"icon-sidemenu-chat.png" segueName:@"ChatHomeVc"];
     [self addTitle:@"Invite Friends" imageName:@"icon-sidemenu-invite.png" segueName:@""];
    [self addTitle:@"Settings" imageName:@"icon-sidemenu-setting.png" segueName:@"slidingToSettings"];


    [super viewDidLoad];

    UITapGestureRecognizer *tapAction1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(profileVC:)];
    tapAction1.numberOfTapsRequired = 1;
    profilePic.userInteractionEnabled = YES;
    [profilePic addGestureRecognizer:tapAction1];

    username  = [[NSUserDefaults standardUserDefaults]
                   stringForKey:@"UserName"];
    profilestr = [[NSUserDefaults standardUserDefaults] stringForKey: @"UserProfilePic"];
    self.lblUserName.text = username;
    [profilePic setImageWithURL:[NSURL URLWithString:profilestr] placeholderImage:[UIImage imageNamed:@"user"]];
    self.profilePic.layer.cornerRadius = self.profilePic.frame.size.width / 2;
    self.profilePic.clipsToBounds = YES;
    // Do any additional setup after loading the view.
}

-(void)addTitle:(NSString *)title imageName:(NSString *)imageName segueName:(NSString *)segue
{
    NSMutableDictionary *dic = [[NSMutableDictionary alloc]init];
    [dic setObject:title forKey:@"title"];
    [dic setObject:imageName forKey:@"image"];
    [dic setObject:segue forKey:@"segue"];
    [arrOfOptions addObject:dic];
}

- (void)profileVC:(UITapGestureRecognizer *)tapGesture
{
   [self performSegueWithIdentifier:@"SideMenuToProfileView" sender:self];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"SideMenuToProfileView"])
    {
        ProfileViewController *destViewController = segue.destinationViewController;
        destViewController.senderStr = @"fromUserSideMenu";
    }
}

【解决方案1】：

创建一个背景视图，其大小等于设备的宽度和高度。将点击手势识别器添加到视图并在点击视图时隐藏侧边菜单。或者您也可以使用按钮来获得相同的功能，在按钮操作方法中编写代码。

如下操作

 var backgroundView : UIView = UIView()

 func createBackgroundView()
{
    backgroundView = UIView(frame: CGRect(x: 0, y: 0, width: ScreenSize.SCREEN_WIDTH, height: ScreenSize.SCREEN_HEIGHT))
    backgroundView.tag = 10
    backgroundView.isHidden = true
}

您可以在侧边菜单出现时取消隐藏背景视图
