ios5 - 是否可以包含向预定义区域的向左或向右滑动？

Question

是否可以只允许在屏幕的某些区域滑动？例如，我有一个倒数计时器，要增加或减少它，我想随着时间的推移向左或向右滑动以增加或减少值。这可能吗？还是 UISwipGestureRecogniser 的唯一屏幕特定？

再次感谢！

Answer 1

这是在预定义的 UIView 中进行滑动的代码。确保为您的视图和滑动手势制作一个 IBOutlet：

.h 文件

#import <UIKit/UIKit.h>

@interface home_1_ViewController : UIViewController <UIGestureRecognizerDelegate>

//UISwipeGestureRecognizer properties
@property (strong, nonatomic) IBOutlet UISwipeGestureRecognizer *swipeGestureRecognizerRight;
@property (strong, nonatomic) IBOutlet UISwipeGestureRecognizer *swipeGestureRecognizerLeft;

@property (strong, nonatomic) IBOutlet UIView *viewGestureCountDown;

@end

.m 文件

- (void)viewDidLoad
{
    [super viewDidLoad];

    UISwipeGestureRecognizer *left = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerSwipeleft:)];
    [left setDirection:UISwipeGestureRecognizerDirectionLeft];
    [viewGestureCountDown addGestureRecognizer:left];

    UISwipeGestureRecognizer *right = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerSwiperight:)];    
    [right setDirection:UISwipeGestureRecognizerDirectionRight];
    [viewGestureCountDown addGestureRecognizer:right];
}


- (void)oneFingerSwipeleft:(UISwipeGestureRecognizer *)recognizer 
{ 
    NSLog(@"You swiped Left");
}

- (void)oneFingerSwiperight:(UISwipeGestureRecognizer *)recognizer
{ 
    NSLog(@"You swiped Right");
}

感谢那些帮助提出这个问题的人。完美运行。

您可以尝试使用 UISwipeGestureRecognizer 检测绑定到特定视图的手势，然后将后续逻辑附加到它，例如

 CGPoint point = [recognizer locationOfTouch:0 inView:MyView];
