iOS开发 将html加载到页面上

//记得要引入头文件 #import "WebKit/WebKit.h"
weakself.myWebView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 206,[weakself.view com_width], [weakself.view com_height] - 206)];
NSString *content = result.content;
//给富文本追加js 为了适应屏幕  写死就好 固定的
NSString *headerString = @"<header><meta name='viewport' content='width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no'><style>img{max-width:100%}</style></header>";
[weakself.myWebView loadHTMLString:[headerString stringByAppendingString:content] baseURL:nil];
//注意要把webview加到页面上
[weakself.view addSubview:weakself.myWebView];
