@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(, , self.view.frame.size.width, )];

    [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;

}
