WKWebView使用中遇到的坑

WKWebView使用中遇到的坑

1.在调试中，H5内置弹出框， 在原生中运行不弹出

解决方案：加上下面几行代码

- (void)webView:(WKWebView*)webView runJavaScriptAlertPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(void))completionHandler{

    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:message?:@"" preferredStyle:UIAlertControllerStyleAlert];

    [alertControlleraddAction:([UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

        completionHandler();

    }])];

    [self presentViewController:alertController animated:YES completion:nil];

}

- (void)webView:(WKWebView*)webView runJavaScriptConfirmPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(BOOL))completionHandler{

    //    DLOG(@"msg = %@ frmae = %@",message,frame);

    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:message?:@"" preferredStyle:UIAlertControllerStyleAlert];

    [alertControlleraddAction:([UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {

        completionHandler(NO);

    }])];

    [alertControlleraddAction:([UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

        completionHandler(YES);

    }])];

    [self presentViewController:alertController animated:YES completion:nil];

}

- (void)webView:(WKWebView*)webView runJavaScriptTextInputPanelWithPrompt:(NSString*)prompt defaultText:(NSString*)defaultText initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(NSString*_Nullable))completionHandler{

    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:prompt message:@"" preferredStyle:UIAlertControllerStyleAlert];

    [alertControlleraddTextFieldWithConfigurationHandler:^(UITextField*_NonnulltextField) {

        textField.text= defaultText;

    }];

    [alertControlleraddAction:([UIAlertAction actionWithTitle:@"完成" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

        completionHandler(alertController.textFields[0].text?:@"");

    }])];

    [self presentViewController:alertController animated:YES completion:nil];

}

2.设置cookie ,有时候H5会获取不到

解决办法：

-(void)setTheCookieOfWebView

{

    NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:self.baoFu_token,@"token", nil];

    NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

    //先删除Userid和isbind的cookie

    [_webView evaluateJavaScript:[NSString stringWithFormat:@"document.cookie ='json=%@'",[UIViewController convertToJsonData:dic]] completionHandler:nil];

    NSArray*cookieArray = [NSArrayarrayWithArray:[cookieStoragecookies]];

    for(idobjincookieArray) {

        [cookieStoragedeleteCookie:obj];

    }

}

+(NSString*)convertToJsonData:(NSDictionary*)dict{

    NSError*error;

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:kNilOptions  error:&error];

    NSString*jsonString;

    if(!jsonData) {

        NSLog(@"%@",error);

    }else{

        jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding];

    }

    NSMutableString*mutStr = [NSMutableStringstringWithString:jsonString];

    NSRangerange = {0,jsonString.length};

    //去掉字符串中的空格

    [mutStrreplaceOccurrencesOfString:@" " withString:@"" options:NSLiteralSearch range:range];

    NSRangerange2 = {0,mutStr.length};

    //去掉字符串中的换行符

    [mutStrreplaceOccurrencesOfString:@"\n" withString:@"" options:NSLiteralSearch range:range2];

    returnmutStr;

}
