ios 11中tableView的新特性

1.LargeTitle：

       a. 全局使用：

//    if (@available(iOS 11.0, *)) {

//        [[UINavigationBar appearance] setPrefersLargeTitles:true];

//    } else {

//        // Fallback on earlier versions

//    }

 

    b.在某个controller中使用：

    [self.navigationController.navigationBar setPrefersLargeTitles:YES];

2.ios 10 系统的刷新控件：UIRefreshControl   

UIRefreshControl *refreshControl = [[UIRefreshControl alloc]init];

    [refreshControl addTarget:self action:@selector(beginRefresh) forControlEvents:UIControlEventValueChanged];

    if (@available(iOS 10.0, *)) {

        [table setRefreshControl:refreshControl];

    } else {

        // Fallback on earlier versions

    }

-(void)beginRefresh{

    if ( [table.refreshControl isRefreshing]) {

            [table.refreshControl endRefreshing];

    }

}

 

 

3.UISearchController 

  searchController = [[UISearchController alloc]initWithSearchResultsController:nil];

 

    if (@available(iOS 11.0, *)) {

        self.navigationItem.searchController = searchController;

        self.navigationItem.hidesSearchBarWhenScrolling = false; // 重要，没有这句，会没有效果

    } else {

        table.tableHeaderView = searchController.searchBar;

    }
