在自定义的uiscroview里添加方法。

左边侧滑:
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    CGPoint velocity = [(UIPanGestureRecognizer *)gestureRecognizer velocityInView:self];
    CGPoint location = [gestureRecognizer locationInView:self];
    
    NSLog(@"velocity.x:%f----location.x:%d",velocity.x,(int)location.x%(int)[UIScreen mainScreen].bounds.size.width);
    if (velocity.x > 0.0f&&(int)location.x%(int)[UIScreen mainScreen].bounds.size.width<60) {
        return NO;
    }
    return YES;
}

 

 

右边侧滑:
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    CGPoint velocity = [(UIPanGestureRecognizer *)gestureRecognizer velocityInView:self];
    CGPoint location = [gestureRecognizer locationInView:self];
    
    NSLog(@"velocity.x:%f----location.x:%d",velocity.x,(int)location.x%(int)[UIScreen mainScreen].bounds.size.width);
    if (velocity.x > 0.0f&&(int)location.x%(int)[UIScreen mainScreen].bounds.size.width>[UIScreen mainScreen].bounds.size.width-60) {
        return NO;
    }
    return YES;
}
