向左滑動推視圖控制器

Question

如何使用panGesture向左滑動視圖控制器（平移左側）？ 目前使用SwipeRightToPopController github庫來實現彈出視圖控制器的平移權。

Answer 1

試試這個：

在viewDidLoad中：

UISwipeGestureRecognizer *swipeLeftGesture=[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGesture:)]; 
[self.view addGestureRecognizer:swipeLeftGesture]; 
swipeLeftGesture.direction=UISwipeGestureRecognizerDirectionLeft;// change direction as per your needs 

其選擇方法：

-(void)handleSwipeGesture:(UIGestureRecognizer *) sender 
{ 
    NSUInteger touches = sender.numberOfTouches; 
    if (touches == 2) 
    { 
     if (sender.state == UIGestureRecognizerStateEnded) 
     { 
      //push view controller here  
     } 
    } 
} 

使用移動手勢

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panDetected:)]; 
[self.view addGestureRecognizer:panRecognizer]; 

- (void)panDetected:(UIPanGestureRecognizer *)panRecognizer 
{ 
    CGPoint velocity = [panRecognizer velocityInView:self.view]; 

    NSLog(@"Pan Detected."); 

    if (velocity.x > 0) 
    { 
     NSLog(@"Pan went right."); 
    } 
    else 
    { 
     NSLog(@"Pan went left.");  

     if (panRecognizer.state == UIGestureRecognizerStateChanged) 
      NSLog(@"push here "); 

     [self performSegueWithIdentifier:@"Settings" sender:panRecognizer]; 
    } 
}

嘗試這樣

在viewDidLoad中

let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipes)) 
let rightSwipe = UISwipeGestureRecognizer(target: self, action:#selector(handleSwipes)) 

leftSwipe.direction = .left 
rightSwipe.direction = .right 

view.addGestureRecognizer(leftSwipe) 
view.addGestureRecognizer(rightSwipe) 

func handleSwipes(sender:UISwipeGestureRecognizer) { 
    if (sender.direction == .left) 
    { 
     let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil) 
     let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "FirstViewController") as UIViewController 
     self.navigationController?.pushViewController(initialViewControlleripad, animated: false) 
    }if(sender.direction == .right){ 

     let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil) 
     let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "SecondViewController") as UIViewController 
     self.navigationController?.pushViewController(initialViewControlleripad, animated: false) 
    } 
}
