#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;

}
