如何将手势切换回上一个查看ios？

我正试图回到（QueryController）我来自的视图。 但不会发生刷卡操作。。。 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];

}

在

viewDidLoad

方法中添加您的

uisweegesturecognizer

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];
}

在

viewDidLoad

方法中，使用导航堆栈并在gestureAdd

initWithNibName

code的选择器目标处按下ViewController。感谢@Dilip等人。加入viewDidLoad方法修复了它。它现在可以工作了。使用导航堆栈并在
