Unity2018接入第四方支付，采用WKWebView

unity跳转ios的webview，UnityAppController.mm

// 跳转方法
- (void)openBrower:(NSNotification *)notification
{
    NSString* strHtml = [notification.userInfo objectForKey:@"text"];
    BrowserViewController *browController = [[BrowserViewController alloc]init];
    browController.strHtml = strHtml;
    GetAppController().window.rootViewController = browController;
}
// 启动
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    //增加一个通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(openBrower:) name:@"OpenBrower" object:nil];
    return YES;
}

打开浏览器网页

NSString *base64String = [childdic valueForKey:@"strMessage"] ;
NSData *data = [[NSData alloc]initWithBase64EncodedString:base64String options:NSDataBase64DecodingIgnoreUnknownCharacters];
NSString *stringHtml = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
[[NSNotificationCenter defaultCenter] postNotificationName:@"OpenBrower" object:nil userInfo:@{@"text":stringHtml}];
