开发中使用到UITableView的各个技术点

     直接上代码，进行注释，更加明了

     - (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view.

   // 设置标题

    self.navigationItem.title = @"我的";

    //设置视图的背景图片

    UIImage *backG = [UIImage imageNamed:@"250"];

    self.view.layer.contents = (__bridge id)(backG.CGImage);

    

   #ifdef moreThanIOS7

   //iOS7之后视图view从最顶点（0，0，0，0）开始。设置以后属性之后，与iOS7之前一致，从UINavigationBar下面开始

    self.edgesForExtendedLayout = UIRectEdgeNone;

   #endif

    //设置头像以及最新轻博客图片及内容

    [self headImageView];

   

    //注意要设置属性为UITableViewStyleGrouped，才能是设置多个section，如果继承于UITableViewController，默认是UITableViewStylePlain，无法设置多个section

     tableV = [[UITableView alloc]initWithFrame:CGRectMake(0,headImg.frame.size.height,ScreenWidth,Screenheight-headImg.frame.size.height-49) style:UITableViewStyleGrouped];

    tableV.delegate = self;

   //设置该属性，tableview无法滚动

//    _tableV.scrollEnabled = NO;
