ios - 如何使用通知请求禁用 View ？

Question

如何启用和禁用本地通知？

当我第一次打开应用程序时，会出现带有通知请求的 View 。如何在应用程序开始时让这个 alertView 消失以进行通知？我想为此在设置中使用一个开关。

那么，这是一种从 AppDelegate 转换此代码的方法，在 settingsView 的切换中？

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)];
}

或者我可以设置从开始到开启通知？在我使用开关创建或不创建通知之后。

在 settingsView.m 文件中试试这个

       - (IBAction)switchValueChanged:(id)sender
     {
if (self.switchNotificationSetting.isOn)
{
    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)];
    }
}
 }

第二次以后它不会显示警报，用户允许通知或不允许，警报只出现一次。你需要添加 iboutlet 和 uiswitch 的 Action
