Ios 使用pangesture在父视图中移动UIView

我想移动父视图中的视图，我正在使用UIPanGestureRecognizer移动视图。我正在使用下面的代码

-(void)move:(UIPanGestureRecognizer *)recognizer {
    CGPoint touchLocation = [recognizer locationInView:self.customeView];

    self.view.center = touchLocation;
}

我想使用locationInView来移动视图，而不是TranslationView。有人能帮助我如何使用locationInView在parentview中移动视图吗？

您使用

UIPangestureRecognitizer的方法是正确的。您可能缺少开始和结束手势状态处理。这是我刚刚在样例项目（Swift）中整合的完整解决方案，其中panView是视图控制器根视图的一个子类

class ViewController: UIViewController {

    @IBOutlet weak var panView: UIView!

    // records the view's center for use as an offset while dragging
    var viewCenter: CGPoint!

    override func viewDidLoad() {
        super.viewDidLoad()
        panView.addGestureRecognizer(UIPanGestureRecognizer(target: self, action: #selector(self.dragView)))
    }

    func dragView(gesture: UIPanGestureRecognizer) {
        let target = gesture.view!

        switch gesture.state {
        case .began, .ended:
            viewCenter = target.center
        case .changed:
            let translation = gesture.translation(in: self.view)
            target.center = CGPoint(x: viewCenter!.x + translation.x, y: viewCenter!.y + translation.y)
        default: break
        }
    }

}

你可以试试这个

@interface ViewController ()
@property (weak, nonatomic) IBOutlet UIView *panView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    //self.panView = self.panView -> self.view . self.panView is direct child of self.view

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


    // Do any additional setup after loading the view, typically from a nib.
}

-(void)move:(UIPanGestureRecognizer *)recognizer {
    CGPoint centerPoint = [recognizer locationInView:self.view];
    self.panView.center = centerPoint;
}
}

将可拖动视图的坐标从子视图转换到父视图是否存在问题？或者让它移动？我在使用TranslationView时遇到问题，因此我使用locationInView。感谢您的回复@Kyle Clegg，但我想在UIPangestureRecognitor方法中使用locationInView。但您在上面的代码中使用的是视图中的平移。如何限制平移视图应仅在另一个视图中移动（具有特定帧）
