iOS 带箭头菜单选项弹窗LFPopupMenu

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];

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'
