如何在 iOS 中一起加载 webview 中的两个 url？

Question

我正在网络视图中加载 url。我有两种类型的数据要显示

1)文本(html 字符串)

2)url

这是我的代码

To display text

[self.webView loadHTMLString:[self.arr objectAtIndex:indexPath.row][@"text"] baseURL:nil];

To display url

NSString *str = [NSString stringWithFormat:@"%@%@",URL,strpdf];
        NSURL *websiteUrl = [NSURL URLWithString:str];
        NSURLRequest *urlRequest = [NSURLRequest requestWithURL:websiteUrl];
        [self.webView loadRequest:urlRequest];

问题是当我加载两个数据时，数据被覆盖。我想在 webview 中显示这两个数据但现在只有文字或图片显示。

有什么解决办法。

我的演示如下：

#import "ViewController.h"

@interface ViewController ()<UIWebViewDelegate>

@property(nonatomic, strong) UIWebView *webView;

@property (nonatomic, copy) NSString *html_str;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self initUI ];
}

- (void)initUI {

    _html_str = @"I love google...";  // the html text you want

    CGRect frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height);
    _webView = [[UIWebView alloc] initWithFrame:frame];
    _webView.delegate = self;

    NSString *str = [NSString stringWithFormat:@"http://chsezhsan195030.e-fae.cn/"];
    NSURL *websiteUrl = [NSURL URLWithString:str];
    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:websiteUrl];
    [self.webView loadRequest:urlRequest];

    [self.view addSubview:self.webView];


}

#pragma mark - webview delegate

- (void)webViewDidFinishLoad:(UIWebView *)webView {


     NSString *script_str = [NSString stringWithFormat:@"var body = document.getElementsByTagName('body')[0];\
     var script = document.createElement('div');\
     script.innerText = '12345678'%@;\
     script.style.width = window.innerWidth + 'px';\
     script.style.height = '300px';\
     script.style.backgroundColor = '#eeeeee';\
     body.appendChild(script); \
     body.insertBefore(script, body.childNodes[0]);",_html_str];

    NSString *function = [NSString stringWithFormat: @"var script = document.createElement('script');\
    script.type = 'text/javascript';\
    script.text = \'function myFunction() { \
 %@ };'\
    document.getElementsByTagName('head')[0].appendChild(script);", script_str];

    [self.webView stringByEvaluatingJavaScriptFromString:function];

    [self.webView stringByEvaluatingJavaScriptFromString:@"myFunction()"];

}

@end

但是你要注意大部分url是为了注入js代码而被阻止的，特别是httpsurl，所以你不能插入上面的html文本google 的索引页。
