Three ways to reference iOS development WebView

1 simplest and most basic

Nsurl *url = [Nsurl urlwithstring:@ "http://www.baidu.com"];

Nsurlrequest *request = [Nsurlrequest Requestwithurl:url];

[Self.webview Loadrequest:request];

2 Refer to Import project files remember to put the corresponding JS CSS file

NSString * Htmlpath = [[NSBundle mainbundle] pathforresource:@ "Mall" oftype:@ "html"];

NSString * Htmlcont = [NSString stringwithcontentsoffile:htmlpath encoding:nsutf8stringencoding Error:nil]; Get the current app's root directory

NSString *path = [[NSBundle mainbundle] bundlepath];

Nsurl *baseurl = [Nsurl Fileurlwithpath:path]; HTML that is loaded by means of BaseURL

Files such as js,css,img can be loaded in HTML in relative directories

[Self.webview Loadhtmlstring:htmlcont Baseurl:baseurl];

3 referencing the files in the sandbox (files need to be downloaded to the sandbox, and subsequent collation of the relevant code)

Nsarray *paths = Nssearchpathfordirectoriesindomains (Nsdocumentdirectory,nsuserdomainmask,yes);

NSString *docdir = [Paths objectatindex:0];

NSString *filepath = [Docdir stringbyappendingpathcomponent:@ "mall.html"];

Nsurl *baseurl = [Nsurl Urlwithstring:filepath];

NSString *htmlstring=[[nsstring Alloc]initwithcontentsoffile:filepath encoding:nsutf8stringencoding Error:nil];

[Self.webview loadhtmlstring:htmlstring Baseurl:baseurl];
