MFSideMenu full size pan gesture - objective-c

Question

I use MFSideMenu in my application, and i can show the menu using a pan gesture on the navigation bar only. I would like it to work on the whole screen, like on the facebook app.!
I've tried changing this line (l.39 in MFSideMenuManager.m)
[controller.navigationBar addGestureRecognizer:recognizer];
to this :
[controller.view addGestureRecognizer:recognizer];
but it just won't work.
Do you have any idea of what i should edit for it to work?
Thank you for your help

Answer 1

I finally succeeded making it work. The gesture is actually already implemented but working only if the menu is hidden. We have to remove 2 conditions to make sure it works both ways
There are two lines to edit in the MFSideMenuManager.m
In the gestureRecognizerShouldBegin: method
if([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
if([gestureRecognizer.view isEqual:self.navigationController.view] &&
self.navigationController.menuState != MFSideMenuStateHidden) return YES;
becomes
if([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
if([gestureRecognizer.view isEqual:self.navigationController.view]) return YES;
In the navigationControllerPanned: method, just remove the if line
- (void) navigationControllerPanned:(id)sender {
if(self.navigationController.menuState == MFSideMenuStateHidden) return;
[self handleNavigationBarPan:sender];
}
becomes
- (void) navigationControllerPanned:(id)sender {
[self handleNavigationBarPan:sender];
}
And it works!
It is not a really good practice to edit a library, but it is easy if you want to go further to add a boolean option to MFSideMenu to make it configurable.

Answer 2

I don't know the MFSideMenuManager but if the bar is draggable I expect it to have a UIPanGestureRecognizer with a line
[self.navigationController.navigationBar addGestureRecognizer:gestureRecognizer];
So what you do is replace the navigation bar with the view for the whole navigation controller
[self.navigationController.view addGestureRecognizer:gestureRecognizer];
