接触到了向左右滑动的手势,上代码。
以下实现了,向左滑动时,提出向左滑动的提示,当向右滑动时,提出向右滑动的提示。
- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.title=@"可以向左(右)滑动"; //向右滑动 UISwipeGestureRecognizer *recognizerLeft; recognizerLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFromLeft:)]; [recognizerLeft setDirection:(UISwipeGestureRecognizerDirectionLeft)]; [self.view addGestureRecognizer:recognizerLeft]; //向左滑动 UISwipeGestureRecognizer *recognizerRight; recognizerRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFromRight:)]; [recognizerRight setDirection:(UISwipeGestureRecognizerDirectionRight)]; [self.view addGestureRecognizer:recognizerRight]; } #pragma -mark -手势滑动 //向左滑动 -(void)handleSwipeFromLeft:(UISwipeGestureRecognizer *)recognizer { NSLog(@"-------进入向左手势滑动姿势-------------"); if (recognizer.direction==UISwipeGestureRecognizerDirectionLeft) { UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"提醒" message:@"进入向左手势滑动姿势" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil]; [alert show]; } } //向右滑动 -(void)handleSwipeFromRight:(UISwipeGestureRecognizer *)recognizer { NSLog(@"-------进入向右手势滑动姿势-------------"); if (recognizer.direction==UISwipeGestureRecognizerDirectionRight) { UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"提醒" message:@"进入向右手势滑动姿势" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil]; [alert show]; } }
