如何发送固定时间的推送通知？

Question

我是一个新的IOS开发人员，我以前从未做过推送通知或本地的工作。

用户需要设置一个小时，以采取推送通知。什么需要做我的申请？

我的应用程序，每天发送给每一个在小时前设置推送通知的用户。推送通知总是相同的。

有谁可以帮我？我怎么能这么做？

用于设置本地通知的参考链接：

//替换第一个链接的代码中的下面的方法

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.

//-- Set Notification
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

// Handle launching from a notification
UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (locationNotification) {
    // Set icon badge number to zero
    application.applicationIconBadgeNumber = 0;
}

return YES;
}

您可以对本地通知执行此操作。

NSDate *date = self.datePicker.date;

UILocalNotification *note = [[UILocalNotification alloc] init];
note.alertBody = @"Say Hello!";
note.fireDate = date;

[[UIApplication sharedApplication] scheduleLocalNotification:note];

此外，您还可以使用来自parse.com的框架进行远程通知。
