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];
}
}
