iOS -OC调用js页面

我们这边和h5商量好传递一个结构体参数过去，然后由于解析的问题，导致我这里传递的参数，到h5那边不执行那边的方法

-(void)loginCallBack

{

NSDictionary *dic;

user = [IBKeychain loadValueForKey:kUserKey];

if (user) {

dic= @{

@"id":[user objectForKey:@"userId"],

@"token":[user objectForKey:@"access_token"],

@"appTag":@"IOS"

};

}else{

dic= @{

//               @"id":@"",

@"token":@"",

@"appTag":@"IOS"

};

}

NSData *jsonData = [NSJSONSerialization

dataWithJSONObject:dic options:0

error:nil];

NSString *result = [[NSString alloc] initWithData:jsonData  encoding:NSUTF8StringEncoding];

NSString *jsStr = [NSString stringWithFormat:@"appLoginCallBack('%@');",result];

[self.webView  stringByEvaluatingJavaScriptFromString:jsStr];

//    return;

}

然后这样就可以调用方法了

- (void)webViewDidFinishLoad:(UIWebView *)webView

{

[self hideLoadingView];

[self loginCallBack];

}
