OC用UIWebView加载这个链接

OC代码:

.h

#import "ZWBaseVC.h"

#import <WebKit/WebKit.h>

#import <JavaScriptCore/JavaScriptCore.h>

@interface ZWPayVC : ZWBaseVC<UIImagePickerControllerDelegate,UINavigationControllerDelegate,UIWebViewDelegate>

/**  加载html的容器webView  */

@property (nonatomic, strong) UIWebView *webview;

/**  js与oc 交互桥梁  */

@property (nonatomic, strong) JSContext *jsContext;

/**  链接参数字符串  */

@property (nonatomic, strong) NSString *urlmsg;

@end

.m

#import "ZWPayVC.h"

@interface ZWPayVC ()

@end

@implementation ZWPayVC

- (void)viewDidLoad {

         [super viewDidLoad];

         [self loadWebView:self.urlmsg];

}

//加载网页

- (void)loadWebView:(NSString *)url_aa {

            CGRect rect = [UIScreen mainScreen].applicationFrame;

            _webview = [[UIWebView alloc] initWithFrame:rect];

            NSURL *url = [NSURL URLWithString:url_aa];

            NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

            [_webview loadRequest:request];

            [self.view addSubview:_webview];

            _webview.delegate=self;

}

- (BOOL) webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType) navigationType {

               NSDictionary *headers = [request allHTTPHeaderFields];

               BOOL hasReferer = [headers objectForKey:@"Referer"]!=nil;

               if (hasReferer) {

                             // .. is this my referer?

                             return YES;  

              } else {

                          // relaunch with a modified request 

                dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

dispatch_async(dispatch_get_main_queue(), ^{

                                NSURL *url = [request URL];

                                NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

                               [request setHTTPMethod:@"GET"];

                               [request setValue:@"ja.longliqi.com://" forHTTPHeaderField: @"Referer"]; 

                               [self.webview loadRequest:request];

                           });

                 });

          return NO;
