Second, simple usage

Super simple, 2 lines of code integration, Xib 0 code integration, just drag a view associated Lfbadge class to

Pod import pod ' Lfkit/lfbadge ' supported

// general view _badge1 = [[Lfbadge alloc] init];[ _badge1 Addtotabbaritem:_view1]; // barbuttonitem superscript _badge2 = [[Lfbadge alloc] init];[ _badge2 AddToBarButtonItem:self.navigationItem.rightBarButtonItem]; // tabbaritem superscript _badge3 = [[Lfbadge alloc] init];[ _badge3 AddToTabBarItem:self.tabBarItem];

Assign value
@ "0" or nil hidden, @ "" shows red dots, numeric strings greater than Maxcount display maxcount++, other strings are displayed as they are (you can also display new)
_badge1.count = @ "1"

Iii. more Usage 1. Drag-and-drop removal

Add a clear callback has a drag function, no drag-and-drop function

_badge1.clearblock = ^{        NSLog (@ " clear Unread message corner Mark ");    };
