How to add it to UITabbarController like path

[sushipan]

I want to do the effect like Path ,and how to add it to UITabbarController?
when I add it to UITabbarController,I can't add the gray background view to the key window correctly ,because when I use PushView Controller,the AwesomeMenu will not disappear.

I find a solution

Notice this: “self” is a UIView,the custom tabbar
-(void)iniMenu:(CGFloat )itemWidth{

CGFloat delta = [UIScreen mainScreen].bounds.size.height-64-self.bounds.size.height;
self.menu = [[AwesomeMenu alloc] initWithFrame:CGRectMake(0, -delta, self.bounds.size.width, delta+self.bounds.size.height) startItem:self.startMenuItem menuItems:self.menuItems];
self.menu.delegate = self;


CGPoint startPoint =  CGPointMake((itemWidth-self.startMenuItem.bounds.size.width)/2.0,(self.bounds.size.height-self.startMenuItem.bounds.size.height)/2.0+delta);

self.menu.startPoint = startPoint;

self.menu.menuWholeAngle = M_PI_2;

self.menu.timeOffset = 0.0;

[self addSubview:self.menu];

}
-(id)hitTest:(CGPoint)point withEvent:(UIEvent *)event {

CGPoint hitpoint = [self convertPoint:point fromView:self];

if ([self pointInside:hitpoint withEvent:event]) {//hit custom tabbar

    return [super hitTest:point withEvent:event];
}

for (AwesomeMenu Item *item in self.menu.menuItems) {

    CGPoint hitPoint = [item convertPoint:point fromView:self];
    if ([item pointInside:hitPoint withEvent:event]){
        NSLog(@"item");
        return item;
    }

}

if(self.menuReallyExpanded){//because one tap will call this method two times ,so we have to detect if the menu is really expanded or really close 
    [self.menu close];
    return self;
}else{
    return [super hitTest:point withEvent:event];
}

}
