如何发送固定时间的推送通知？

Question

我是新 IOS 开发人员，我以前从未使用过推送通知或本地。

用户需要设置一个小时，以获取推送通知。我的申请需要做什么？

我的应用程序，每天为每个在小时前设置推送通知的用户发送。推送通知始终相同。

谁能帮帮我？我该怎么做？

Answer 1

Link 参考设置本地通知：

//在第一个link的代码

中替换Appdelegate.m中的以下方法

- (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;
}

Answer 2

您可以为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];

您还可以使用 parse.com 中的框架进行远程通知
