一、效果图
由于是模拟器缩得比较小，一些细线可能显示不出来，不是bug哈。
二、用法
LFPopupMenuItem *item1 = [LFPopupMenuItem createWithTitle:@"小视频" image:[UIImage imageNamed:@"icon_menu_record_normal"]]; LFPopupMenuItem *item2 = [LFPopupMenuItem createWithTitle:@"拍照" image:[UIImage imageNamed:@"icon_menu_shoot_normal"]]; LFPopupMenuItem *item3 = [LFPopupMenuItem createWithTitle:@"相册" image:[UIImage imageNamed:@"icon_menu_album_normal"]]; self.items = @[item1, item2, item3]; LFPopupMenu *menu = [[LFPopupMenu alloc] init]; [menu configWithItems:self.items action:^(NSInteger index) { NSLog(@"点击了第%zi个",index); }]; [menu showArrowToView:sender];
更多方法见.h文件，有详细注释

这只是LFKit的一个子库，LFKit地址https://github.com/zhanglinfeng/LFKit
只需LFPopupMenu的 pod 'LFKit/Component/LFPopupMenu'
需要LFKit中所有自定义控件的pod 'LFKit/Component'
需要总库的 pod 'LFKit'
