1.創建webview

UIWebView *_myWebView = [[UIWebView allow]initWithFrame :bounds];

_myWebView.delegate=self;//代理

[self.view addSubview:_myWebView];

2.網絡請求數據加載到webview上

NSString * urlString=[NSString stringWithFormat:@"%@",@"http://www.baidu.com"]; //l鏈接一定加http或者https不然加載不出來

NSString *encodeStr = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; ?//轉碼防止鏈接有中文

NSURL *url = [NSURL URLWithString:encodeStr];?

[_myWebView loadRequest:request];

3.實現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; ?//獲取當前的URL ?根據當前的URL判斷跳轉邏輯

NSLog(@"host == %@",host);

return YES;

}

4 原生點擊事件 webview返回上個webview

[_myWebView goBack];
