1.界面切換UI：(UIViewController + UIScrollView)

self.pagerController= [[DMPagerViewController alloc]initWithViewControllers: @[_controllerCamera,_controllerFeeds,_controllerTimeline,]];

self.window= [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]];

[_window makeKeyAndVisible];

_window.rootViewController=self.pagerController;

self.pagerController.delegate=self;

2.等待加載動(dòng)畫（類方法創(chuàng)建初始化對(duì)象，并且添加到容器中顯示）

[LBProgressHUD showHUDto:_vLoading color:CColor(255,255,255) size:48animated:YES];

[LBProgressHUD hideAllHUDsForView:_vLoading animated:YES];

3.彈出菜單框（UIWindow + WindowLevel + 類共創(chuàng)方法獲取創(chuàng)建配置好的對(duì)象 + 顯示方法）

ZFActionSheet *actionSheet = [ZFActionSheet actionSheetWithTitle:nil confirms:@[@"回復(fù)",[NSString stringWithFormat:@"分享%@的搜索號(hào)",_currentActionMoreFriend.username],@"清空已瀏覽消息",@"返回"]newsIndex:-1style:ZFActionSheetStyleDefault];

actionSheet.delegate=self;

[actionSheet showInView:self.view.window];
