Question

我希望在用户提供推送通知权限时显示thanku.html页面（即，当用户点击“确定”按钮以允许通知时）。此页面只能显示一次。

面临的问题：

thanku.htlml页面在后台重新加载。
如果接受通知权限，则每次启动应用时都会打开thanku.html页面。然而，它不应该在重新启动时显示。

我编写的代码：

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    // For show the thank you page
    NSArray *controllers = [SlideNavigationController sharedInstance].viewControllers;

    for (id obj in controllers) {
        if([obj isKindOfClass:[ViewController class]])
        {
            ViewController *controller = (ViewController *)obj;

            controller.titleOfController = @"Thank you";
            controller.urlStr = @"http://www.7dci.com.au/lagarto/thankyou.html";
            [controller showAtAppearTime];

            [[SlideNavigationController sharedInstance] popToViewController:controller animated:YES];
            return;
        }
    }

    ViewController *controller = [[UIStoryboard storyboardWithName:@"Main" bundle:nil ] instantiateViewControllerWithIdentifier:@"ViewController"];
    controller.titleOfController = @"Thank you";
    controller.urlStr = @"http://www.7dci.com.au/lagarto/thankyou.html";
    [controller showAtAppearTime];
    [[SlideNavigationController sharedInstance] pushViewController:controller animated:YES];
}

在viewdidload视图控制器中：

 [self showAtAppearTime];

而showAtAppearTime是：

- (void)showAtAppearTime
{
    [webView setDelegate:self];

    [self setEmptyWebview];

    titleLbl.text = @"saurabh";
    if(self.titleOfController.length > 0)
        titleLbl.text = self.titleOfController;
    [[NSURLCache sharedURLCache] removeAllCachedResponses];
    NSString *urlAddress = @"http://7dci.com.au/lagarto/menu.html";
    if(self.urlStr.length > 0)
        urlAddress = self.urlStr;
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [webView loadRequest:requestObj];
}

而setEmptyWebview是

NSString *urlAddress = @"";

NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
if(![[[NSUserDefaults standardUserDefaults] objectForKey:@"isFirstTime"] isEqualToString:@"Yes"]){
    [[NSUserDefaults standardUserDefaults] setObject:@"Yes" forKey:@"isFirstTime"];
    [[NSUserDefaults standardUserDefaults] synchronize];
    //Write your required code to set html here
} }

希望这会对你有所帮助
