PinterestLikeMenu

A kind of pop-up menu

How to:

First, the menu can be initialized with:

    PinterestLikeMenuItem *item0 = [[PinterestLikeMenuItem alloc] initWithImage:[UIImage imageNamed:@"center"]
                                                                       selctedImage:[UIImage imageNamed:@"center-highlighted"]
                                                                      selectedBlock:^(void) {
                                                                          NSLog(@"item 0 selected");
                                                                      }];
    PinterestLikeMenuItem *item1 = [[PinterestLikeMenuItem alloc] initWithImage:[UIImage imageNamed:@"center"]
                                                                       selctedImage:[UIImage imageNamed:@"center-highlighted"]
                                                                      selectedBlock:^(void) {
                                                                          NSLog(@"item 1 selected");
                                                                      }];
    PinterestLikeMenuItem *item2 = [[PinterestLikeMenuItem alloc] initWithImage:[UIImage imageNamed:@"center"]
                                                                       selctedImage:[UIImage imageNamed:@"center-highlighted"]
                                                                      selectedBlock:^(void) {
                                                                          NSLog(@"item 2 selcted");
                                                                      }];
    NSArray *submenus = @[item0, item1, item2];
    
    self.menu = [[PinterestLikeMenu alloc] initWithSubmenus:submenus];

To use this pop-up menu, you should add a long press gesture recognizer to the target view with:

- (void)popPinterestMenu:(UIGestureRecognizer *)gesture
{
    CGPoint location = [gesture locationInView:self.view.window];
    if (gesture.state == UIGestureRecognizerStateBegan)
    {
        // set the start point where the menu showing up
        self.menu.startPoint = location;
        [self.menu show];
    }
    else if (gesture.state == UIGestureRecognizerStateChanged)
    {
        [self.menu updataLocation:location];
    }
    else
    {
        [self.menu finished];
        self.menu = nil;
    }
}
