The implementation method of scrollView rolling after sliding a segment on the courier flower new feature interface. The new feature scrollview

1. Make scrollView not scroll by user finger

Self. scrollView. scrollEnabled = NO;

2. Add a gesture to scrollView

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

[Self. scrollViewaddGestureRecognizer: gesture];

3. Process scrollView gestures

# Pragma mark Gesture Recognition callback Method

-(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;

}

}
