速遞花新特性介面滑動一段後scrollView才滾動的 實現方法，新特性scrollview

1.讓 scrollView不可以根據使用者手指滾動

self.scrollView.scrollEnabled =NO;

2.給 scrollView添加手勢

    UIGestureRecognizer *gesture = [[UIPanGestureRecognizeralloc] initWithTarget:selfaction:@selector(dragView:)];

    [self.scrollViewaddGestureRecognizer:gesture];

3.處理scrollView的手勢

#pragma mark 手勢辨識器回調方法

- (void)dragView:(UIPanGestureRecognizer *)gesture{

   switch (gesture.state) {

        caseUIGestureRecognizerStateBegan:

           _startPoint = [gesture translationInView:gesture.view];

           break;

            

        caseUIGestureRecognizerStateEnded:

           CGPoint endPoint = [gesture translationInView:gesture.view];

           if (_startPoint.x - endPoint.x >40) {

               CGPoint start = self.scrollView.contentOffset;

               CGPoint end = CGPointMake(start.x +100, 0);

                [self.scrollViewsetContentOffset:end animated:YES];

            }

           break;

    }

}
