如何在 ios objective c 中使用 uigesturerecognizer 滑动自定义五个子视图

Question

我正在使用 *UISwipeGesture Recognizer，但现在只能使用两个视图，我们可以左右进行操作，但现在需要五个 UIview 才能显示为滑动，请帮帮我？

我只需要以下两个方向：

@左方向。 @正确的方向。

我想在我的视图中向左和向右滑动五个视图。

Answer 1

您可以通过iOS中的方法实现。

使用UIScrollView添加你想滑动的视图然后设置contentSize，然后设置enablePaging = YES，就完成了。
如果您的视图属于视图控制器，您可以使用 UIPageViewController 并添加 set viewControllers 属性并设置滚动方向（垂直或水平）并完成。
如果你想通过 SwipeGestureRecognizer 处理它，你仍然可以这样做，在视图中添加手势识别器，然后将你想要滑动的所有视图作为子视图添加到其中，在向左和向右滑动时，您可以通过链接其框架将下一个或上一个视图放在前面，以跟踪哪个应该是当前可见视图以及上一个和下一个视图是什么，您可以保留一个适当的整数并在开始时将其值设置为 0 ，向左滑动递增 1，向右滑动递减，它应该始终为 0<=index<5.

编辑（使用滑动手势的示例代码） 代码仅用于为您指明正确的方向。我正在创建视图并将它们添加到 viewDidAppear 中的子视图，当然你可以在任何你想做的地方做（也可以在 viewDidLoad 中）。

添加两个属性

@property (nonatomic, strong) NSMutableArray *views;// to hold subviews
@property (nonatomic, assign) NSInteger index;// to keep track which view is currently visible
@property (nonatomic, assign) BOOL viewsCreated;

现在我要添加一些视图并将手势识别器添加到那里的超级视图

      - (void)viewDidAppear:(BOOL)animated
    {
        [super viewDidAppear:animated];
        // Adding an if condition so we create views only once other wise you can take this code to viewDidLoad method
        if (!_viewCreated)
        {
             _viewsCreated = YES;
             int xPos  = 0;
            _views = [NSMutableArray new];
            for (int i = 0; i< 5; i ++)
            {
                CGRect frame = CGRectMake(xPos, 0, self.view.bounds.size.width, self.view.bounds.size.height);
                if (i == 0)
                {
                    //  Create MapView object and add it to _views array
                    MKMapView *mapView = [[MKMapView alloc] initWithFrame:frame];
                    [self.view addSubview:mapView];
                    [_views addObject:mapView];
                }
                if (i == 1)
                {
                    // Create tableView object and add it to _views array
                    UITableView *tableView = [[UITableView alloc] initWithFrame:frame style:UITableViewStylePlain];
                    //set tableView delegate and datasource
                    tableView.delegate = self;
                    tableView.dataSource = self;
                    [_views addObject:tableView];
                    [self.view addSubview:tableView];
                }
                if (i == 2)
                {
                    // Create an imageView and add it to _views array
                    UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame];
                    //Set image
                    //imageView.image = <image>;
                    [_views addObject:imageView];
                    [self.view addSubview:imageView];
                }
                if (i == 3)
                {
                    //Create whatever view you want and add it to array and subView as to self.view as well
                }
                if (i == 4)
                {
                    //Create whatever view you want and add it to array and subView as to self.view as well
                }
            }

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

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

}

- (void)onSwipeLeft:(UISwipeGestureRecognizer*)swipe
{
    if (_index<4)
    {
        UIView *currentView = [_views objectAtIndex:_index];
        CGRect frame = currentView.frame;
        frame.origin.x = -self.view.bounds.size.width;

        UIView *nextView = [_views objectAtIndex:_index+1];
        [UIView animateWithDuration:0.5 animations:^{
            currentView.frame = frame;
            nextView.frame = self.view.bounds;
        }];
        _index++;
    }
}
    - (void)onSwipeRight:(UISwipeGestureRecognizer*)swipe
    {
        if (_index>1)
        {
            UIView *currentView = [_views objectAtIndex:_index];
            CGRect frame = currentView.frame;
            frame.origin.x = self.view.bounds.size.width;

            UIView *nextView = [_views objectAtIndex:_index-1];

            [UIView animateWithDuration:0.5 animations:^{
                currentView.frame = frame;
                nextView.frame = self.view.bounds;
            }];
            _index--;
        }
    }
