1.创建webview
UIWebView *_myWebView = [[UIWebView allow]initWithFrame :bounds];
_myWebView.delegate=self;//代理
[self.view addSubview:_myWebView];
2.网络请求数据加载到webview上
NSString * urlString=[NSString stringWithFormat:@"%@",@"http://www.baidu.com"]; //l链接一定加http或者https不然加载不出来
NSString *encodeStr = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; //转码防止链接有中文
NSURL *url = [NSURL URLWithString:encodeStr];
[_myWebView loadRequest:request];
3.实现webview 代理
#pragma mark - NJKWebViewProgressDelegate
-(void)webViewProgress:(NJKWebViewProgress *)webViewProgress updateProgress:(float)progress
{
self.title = [_myWebView stringByEvaluatingJavaScriptFromString:@"document.title"];
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSString *host = request.URL.absoluteString; //获取当前的URL 根据当前的URL判断跳转逻辑
NSLog(@"host == %@",host);
return YES;
}
4 原生点击事件 webview返回上个webview
[_myWebView goBack];
