- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    // 创建textView
    UITextView *textV = [[UITextView alloc] initWithFrame:CGRectMake(0, 100, self.view.frame.size.width, 400)];
    [self.view addSubview:textV];
    
    // 设置textView边框宽度和颜色
    textV.layer.borderWidth = 2.0f;
    textV.layer.borderColor = [UIColor blackColor].CGColor;
    
    // 获取html数据
    NSString *htmlString = @"<h1>Header</h1><h2>Subheader</h2><p>Some<em>text</em></p><img src='http://blogs.babble.com/famecrawler/files/2010/11/mickey_mouse-1097.jpg'width=70 height=100 />";
    
    // 利用可变属性字符串来接收html数据
    NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType} documentAttributes:nil error:nil];
    
    // 给textView赋值的时候就得用attributedText来赋了
    textV.attributedText = attributedString;
