• Q: How to use PPDragDropBadgeView?

• A: Very simple, you only follow the down code.

PPDragDropBadgeView* badgeView
= [[PPDragDropBadgeView alloc] initWithFrame:CGRectMake(0, 0, 20, 20) dragdropCompletion:^{ NSLog(@"Drag drop done."); }]; badgeView.text = @"6";

• Q: Does it can be customized?
• A: Of course, You can see the propertys provided by me.

    /** The completion block when drag drop done. */
    @property (nonatomic, copy) void(^dragdropCompletion)();
    
    /** The tint color of badge view. Default is red */
    @property (nonatomic, strong) UIColor* tintColor;
    
    /** The text of badge view. */
    @property (nonatomic, strong) NSString* text;
  

you must use addSubview instead of directly use it. like

PPDragDropBadgeView* badge = [[PPDragDropBadgeView alloc] initWithFrame:CGRectMake(10, 10, 25, 25)];
badge.text = @"8";

//you must add to container first instead of [[UIBarButtonItem alloc] initWithCustomView:badge]
UIView* container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
container.backgroundColor = [UIColor clearColor];
[container addSubview:badge];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:container];
