Specify minimum width for child view controllers about frlayerednavigationcontroller

[mronkko]

This code (kind of) does what I would like to achieve. It should be called after pushing or popping view controllers. This is not a perfect solution, but something that worked for a prototype.

-(void) _adjustLayeredNavigationControllerLayerWidths{
NSInteger maxOverLap = 64;
NSInteger maxSpaceForLayers = 128;
NSInteger numberOfLayers = [self.layeredNavigationController.viewControllers count]-1;

if(numberOfLayers==0) return;

CGFloat nextItemDistance = MIN(maxOverLap, maxSpaceForLayers/(CGFloat) numberOfLayers);
CGFloat x=0;

for(UIViewController* viewController in self.layeredNavigationController.viewControllers){
    viewController.layeredNavigationItem.nextItemDistance = nextItemDistance;
    viewController.layeredNavigationItem.currentViewPosition = CGPointMake(x, viewController.layeredNavigationItem.currentViewPosition.y);
    viewController.layeredNavigationItem.initialViewPosition = CGPointMake(x, viewController.layeredNavigationItem.initialViewPosition.y);
    x=x+nextItemDistance;
}
[self.layeredNavigationController doLayout];

}
