【问题描述】：

我试图回到（QueryController）我来自的视图。 但是没有滑动动作发生...... 不知道我错过了什么。

@implementation ProfileController4


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) 
        // Custom initialization

        UISwipeGestureRecognizer * Swiperight=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swiperight:)];
        Swiperight.direction=UISwipeGestureRecognizerDirectionRight;
        [self.view addGestureRecognizer:Swiperight];

        UISwipeGestureRecognizer * Swipeleft=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeleft:)];
        Swipeleft.direction=UISwipeGestureRecognizerDirectionLeft;
        [self.view addGestureRecognizer:Swipeleft];
    
    return self;




-(void)swipeleft:(UISwipeGestureRecognizer*)gestureRecognizer

    //Do what you want here



-(void)swiperight:(UISwipeGestureRecognizer*)gestureRecognizer

    //Do what you want here

    [self performSegueWithIdentifier: @"friendsBackToQuerySeg" sender: self];

//      [[UIViewController alloc] initWithNibName:@"QueryController1" bundle:nil];

【问题讨论】：

使用 Navigation Stack 并将 ViewController 推送到手势的选择器目标

在viewDidLoad方法中添加initWithNibName 代码。

感谢@Dilip 等人。放入 viewDidLoad 方法修复了它。现在可以使用了。

【参考方案1】：

在viewDidLoad 方法中添加您的UISwipeGestureRecognizer 代码..

- (void)viewDidLoad

    [super viewDidLoad];

    UISwipeGestureRecognizer * Swiperight=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swiperight:)];
    Swiperight.direction=UISwipeGestureRecognizerDirectionRight;
    [self.view addGestureRecognizer:Swiperight];

    UISwipeGestureRecognizer * Swipeleft=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeleft:)];
    Swipeleft.direction=UISwipeGestureRecognizerDirectionLeft;
    [self.view addGestureRecognizer:Swipeleft];
