用戶可以滑動或單擊按鈕以在視圖控制器之間導航

Question

我做了什么 ！！

1）我可以在視圖控制器（View1和View2）之間滑動，如下圖所示

圖片1

2）我在ContainerViewController中創建了“拖曳”按鈕，該按鈕允許用戶單擊每個按鈕在這兩個頁面之間導航[類似於輕掃，但單擊此按鈕后便可以進行瀏覽]

這是我的程序的大圖，如下圖所示

我需要什么幫助？

1）我希望有人幫助我實現這兩個按鈕，以在這兩個頁面之間導航[類似於滑動]。 此外，用戶可以滑動或單擊按鈕在頁面之間導航。

我很高興在這里找到願意幫助我和其他人的人

1-ContainerViewController我只創建了兩個按鈕。

2-View1和View2我在這里沒有做任何編碼。

3- ViewSwipe代碼如下

#import "ScrollViewController.h"
#import "View1.h"
#import "View2.h"

@interface ViewController ()
@property (weak, nonatomic) IBOutlet UIScrollView *scrollView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    View1 * V1 = [[View1 alloc]initWithNibName:@"View1" bundle:nil];
    View2 * V2 = [[View2 alloc]initWithNibName:@"View2" bundle:nil];



    [self addChildViewController:V1];
    [self.scrollView addSubview:V1.view];
    [V1 didMoveToParentViewController:self];


    [self addChildViewController:V2];
    [self.scrollView addSubview:V2.view];
    [V2 didMoveToParentViewController:self];

    CGRect V2Frame = V2.view.frame;
    V2Frame.origin.x= self.view.frame.size.width;
    V2.view.frame = V2Frame;

    self.scrollView.contentSize=CGSizeMake(self.view.frame.size.width * 2, self.view.frame.size.height);

}

    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

Answer 1

您可以通過使用UISwipeGestureRecognizer達到Darji所說的

- (void)viewDidLoad {
    [super viewDidLoad];
    UISwipeGestureRecognizer *leftToRightGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftToRightSwipeDidFire)];
    leftToRightGesture.direction = UISwipeGestureRecognizerDirectionRight;
    [self.tabBarController.tabBar addGestureRecognizer:leftToRightGesture];

    UISwipeGestureRecognizer *rightToLeftGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightToLeftSwipeDidFire)];
    rightToLeftGesture.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.tabBarController.tabBar addGestureRecognizer:rightToLeftGesture];
}


- (void)leftToRightSwipeDidFire {
    UITabBar *tabBar = self.tabBarController.tabBar;
    NSInteger index = [tabBar.items indexOfObject:tabBar.selectedItem];
    if (index > 0) {
        self.tabBarController.selectedIndex = index - 1;
    } else {
        return;
    }
}

嘗試此代碼，以便您可以滑動標簽欄

- (void)viewDidLoad {
    [super viewDidLoad];
    UISwipeGestureRecognizer *leftToRightGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftToRightSwipeDidFire)];
    leftToRightGesture.direction = UISwipeGestureRecognizerDirectionRight;
    [self.tabBarController.tabBar addGestureRecognizer:leftToRightGesture];

    UISwipeGestureRecognizer *rightToLeftGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightToLeftSwipeDidFire)];
    rightToLeftGesture.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.tabBarController.tabBar addGestureRecognizer:rightToLeftGesture];
}


- (void)leftToRightSwipeDidFire {
    UITabBar *tabBar = self.tabBarController.tabBar;
    NSInteger index = [tabBar.items indexOfObject:tabBar.selectedItem];
    if (index > 0) {
        self.tabBarController.selectedIndex = index - 1;
    } else {
        return;
    }
}
- (void)rightToLeftSwipeDidFire {
    UITabBar *tabBar = self.tabBarController.tabBar;
    NSInteger index = [tabBar.items indexOfObject:tabBar.selectedItem];
    if (index < tabBar.items.count - 1) {
        self.tabBarController.selectedIndex = index + 1;
    } else {
        return;
    }
}
