I have a setup where I have a Page View Controller
set up to navigate between different views
.
In some of these views I will have a custom drawing view
where the user can draw with their finger to create a picture.
The problem with this, the user is not able to make a drawing gesture left/right
because the page view controller
will take over and navigate to a different view.
I was wondering what a good approach would be to temporarily disable the swiping
for the page view controller
to allow the user to draw
.
I was thinking when the user first interacts with the drawing view
it would disable the page swiping
and create a finished drawing button
. When this button is clicked it would reenable the page swiping
. Does this seem reasonable, or does anybody know of any better approaches?
Using this you can stop Scrolling
for (UIScrollView *view in self.pageViewController.view.subviews) {
if ([view isKindOfClass:[UIScrollView class]]) {
view.scrollEnabled = NO;
}
}
I'd look into this UIGestureRecognizerDelegate
method:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;
Here you can "kill" the page view controller's gesture recognizer by disabling and re-enabling it:
if (/* otherGestureRecognizer is page view controller's */) {
otherGestureRecognizer.enabled = NO;
otherGestureRecognizer.enabled = YES;
}
