    #import "ViewController.h"
    
    @interface ViewController ()
    
    @end
    
    @implementation ViewController
    
    - (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;
        
    }
    
    
    @end
