ios - 滑动手势 View Controller Xcode 5.1.1

Question

我是 Objective-C 和 Xcode 的新手，并且在更改 View 时遇到困难。我知道您可以使用 UIScrollView 在 ImageView 之间滑动，但我想简单地向右滑动以更改 View ，然后向左滑动以返回。我有 AppDelegate.h 和 AppDelegate.m 尚未更改。 ViewController.h 和 ViewController.m 如下:

ViewController.h:

#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@end

ViewController.m:

#import "ViewController.h"
#import "ViewController2.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    //sets up gesture recognizer
    UISwipeGestureRecognizer *swipeRightGesture=[[UISwipeGestureRecognizer alloc]               initWithTarget:self action:@selector(handleSwipeGesture:)];
    [self.view addGestureRecognizer:swipeRightGesture];
    swipeRightGesture.direction=UISwipeGestureRecognizerDirectionRight;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)handleSwipeGesture:(UISwipeGestureRecognizer *)sender 
{
    NSUInteger touches = sender.numberOfTouches;
    if (touches == 2)
    {
        if (sender.state == UIGestureRecognizerStateEnded)
        {
            ViewController2 *vc2 = [[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:nil];
            [self.navigationController pushViewController:vc2 animated:YES];
        }
    }
}

@end

我还有 ViewController2.h 和 ViewController2.m，我已将它们链接到 Storyboard 中的第二个 View ，以及链接到 的手势上面的handleSwipeGesture方法。

Answer 1

- (void)viewDidLoad
{
    [super viewDidLoad];

    UISwipeGestureRecognizer *oneFingerSwipeLeft = [[UISwipeGestureRecognizer alloc]
                                                    initWithTarget:self
                                                    action:@selector(oneFingerSwipeLeft:)] ;
    [oneFingerSwipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
    [[self view] addGestureRecognizer:oneFingerSwipeLeft];
}

- (void)oneFingerSwipeLeft:(UITapGestureRecognizer *)recognizer
{
    NSLog(@"Swiped left");
  // Add your navigation Code Here
}

如果你想使用单指滑动，你可以使用这个。如果您想添加两个手指滑动添加您的

NSUInteger touches = sender.numberOfTouches;
    if (touches == 2)
    {
        if (sender.state == UIGestureRecognizerStateEnded)
        {
        }
    }

以上代码在(void)onefingerSwipeLeft方法中
